The real amazing part is that those half dozen hvac units, plus designing them all to work in sync like a concert symphony--have a total price tag equivalent to my entire house.
Matt as a 40 year HVAC contractor you guys did a bang up job designing and installing these systems. If only all owners and contractors put forth the effort and money to do it right the first time. No second chances down the road with out gutting the house to get at a poorly designed duct system. I can attest workmanship and equipment like this ain’t cheap. But the best never is. Pay me now or pay me and the energy companies later. 👍👍
Great Vid. I fixed my homes comfort issues by: 1. Aero sealing the attic 2. Installing radiant barrier in attic 3. Installing 6” jumper returns to the other 3 upstairs BRs back to the 16” main return 4. Blowing 22” all borate cellulose into attic I have 2 story home with only one 4 tone system on only 1 zone. Before I made these improvements to my attic my home was miserable in the summer. It only had about an R15 of attic insulation and would be 85F on the top floor and 68F in finished basement where the HVAC blower unit is located. After the improvements in attic it’s 72F on the top floor & 70F in basement. No room for whole homer dehumidifier so use portable 60 pint dehumidifier next to blower in basement. My home is wonderfully pleasant now in the entirety of the home. I did all work myself and it probably cost me $2500 in materials to do everything but a lot of hours in the attic. I am so very pleased I did it though as I now have the most comfortable home in our entire community that was built by Ryan Homes in 2002.
Beautiful home! As an HVAC professional the only advice I would have is to get your contractors to plan ahead better on installation, that mini split will work great, but the pump will shortly fail, and is often loud. I've replaced that exact model in a few different places this year already. We always gravity drain and avoid the pumps unless its impossible, but in new construction there normally always a path when its still open framing. Also with a little better planning they could have roughed in the lines to have it sit centered on the wall, over the centered TV and speaker, right now it looks a little out of place. Very carefully planning and measuring at the rough in stage always seems to be a week point with HVAC companies, and it drives me crazy. Love your videos, not trying to be critical, your HVAC ones just always catch my attention and I hope my comments can help someone, thanks!
Ethan Hill, nothing wrong with friendly critiquing. I agree with you 100%. Matt pointed out how all the supply was rigid metal duct. In theory it seems like a good idea. But the down side is that its actually noisier, because there is no flexibility. Ran into this problem on my bosses house. We ended up going back and cutting out some straight pipe and adding in flex on the supply side. You can hear the air travel through the diffusers, especially at a high cfm
@@jamesread8662 I would check the supply register data for cfm delivery between 500 and 700 FPM. You will likely find the registers selected can not handle the CFM without added noise. In most cases 3-5 ft of flex is more than adequate to dampen noises. Swap those registers to something closer to 500 FPM if the throw will still be sufficient and it will likely solve the issues
I don't get why they had that mini split when they had 5 zones and 5 separate HVAC's? That seems to be excessive... You'd think the 5 HVAC systems would be enough!?
I've worked in a number of airtight houses in NH and ME. The most impressive system I saw (and can't give any specifics on) could also humidify in the winter, and all flow with the outside passed through heat exchangers. Bath vents were silent because the fans were remote.The wood stove in the common/dining room had it's own outside air intake. I really like working for rich people. They're the ones who pay for exceptional work. I enjoy your content.
Gotta love the mechanical rooms providing decent access for maintenance - some builders I once worked with wouldn’t have allowed so much “wasted” space. Great job, Matt.
We install this stellar product every day and it is the Best. Complements to your HVAC installer, only suggestion I would give is that all filters should be the same size throughout the entire house, that way you only have to stock 1 size filter and this makes it more likely the filters are changed.
Hope you can help me OFFSHOREAIR. The critics I see above worried me as I was leaning towards MITSUBISHI ELECTRIC TRANE HVAC. The fella above said he's replaced several units like this. Now I am confused what is best AC manufacturer to focus on.
@@cahoonm I dont care for trane due to the parts cost, carrier/goodman have a 10 year warranty. They all have their problems, I like Copeland compressors, trane does make a really good compressor, owning a trane is like having a Mercedes parts are expensive after the warranty ends. I'm a service technician and I used to install for a company so I've seen them all break down. Stay away from rheem-Rudd they suck
@@C.dieslevonankwek7 you must be new to the trade. 90 percent of all the parts in trane, carrier, goodman, are all the same. Parts for trane are no more expensive than others. Infact, trane parts are easier to get than most carrier parts.
I did a somewhat similar system in my house - 3 zones with the Ultra-Aire. Struggled with it all for 10 years, ripped it all out and put in 6 one ton Gree Sapphire Ductless Minis. Fabulous improvement in comfort, control and cost.
@@Floreypottery For what it's worth, because of my age and the humidity of North Carolina, I decided on separate one ton systems. I wanted redundancy for when a system goes down. And I wanted the ability to swap parts. Clean the filters monthly, always use X-Fan with Dry Mode. The Gree+ app works quite well on the Sapphires. They probably have a B series (2nd iteration) by now and I'd inquire about that. Zero complaints though you must carefully make your own template for locating the units and its screws. Use more screws for the brackets especially up top.
Oh yes, and most importantly any one of the Gree Sapphires dumps more water out of the house than the large central Ultra-Aire. The ultra aire is a hot air heater so you are stupidly adding heat to your house. The Gree Sapphires just run a low fan without the heat. Pipe carefully.
Very good detailed information. So refreshing to see a builder actually install havoc systems that will keep the home owner comfortable in all seasons in all area’s of the home. I’m 18years in the hvac industry (mid-west) and more often than not the hvac systems builders installed were the cheapest most basic equipment with poor design, sizing and airflow. Just because you can’t see it doesn’t mean it’s not one of the most important investments in your home.
That trim work is amazing. I do commercial large scale building automation, this residential work is starting to resemble what you’d find in a hospital for their HVAC
It’s hard to just talk about the AC in a house that beautiful thanks for the info... but please revisit the house, it would be nice just to see the craftsmanship thank you!!
Matt: I was an HVAC tech for over 45 years with the last 15 spent as a contractor and I must say that this is one of the most beautiful systems that I've ever seen. I've done both residential and commercial over the years (mostly commercial) and I'm really impressed. I've been retired for about 15 years and I can't believe the changes in technology. Well done.
Beg to differ as a HVAC I am screaming at the nightmare maintenance of these monstrosity. Lazy ass homeowners will never change those filters, way to many systems to track where everything goes to what part of the house. Way too complicated for a homeowners, this will be the house all the companies will avoid.
In 2008, had to replace our first floor furnace & compressor for a 2,800 sq.ft. typical NJ colonial built in '82. After some research I ended up with a Ruud/Rheem Comfort Modulating Furnace/Compressor combo. At that time, not many wanted to touch this product. The guy who installed it for me basically was the kind who could learn something new in 15 minutes (super-smart, not over-smart). He kept saying I was nuts to want to go with something so new and different. On the heating end, the furnace could modulate heat between 5-100% and the fan speed between 10-100%. Cannot remember the cooling ranges. Super happy with the decision to go with a modulating system. The house was always super comfortable with almost no hot or cold spots and my energy bills dropped by close to 40% (not just because of a new unit). In 2005, when it was time to replace the upstairs one, did the same!
Nice to see a high efficiency heat peat pump/AC installation similar to what I installed. "Yes" - these units are efficient for heating down to about 0 deg. F. - which was a big plus for our remodel in the Northwest (winters usually get down to only about to mid 20's F west of the Cascades - so plenty of margin for heat-pump-only heating in the winter). I wish I had the choice of using the Mitsubishi, but I think that one wasn't quite on the market at that time (or something like that). Lennox had a competing unit, but I didn't want a washing machine-shaped outdoor unit in my front yard. I went with the Daikin SkyAir, with a quiet outdoor unit that could hidden behind a bush - that system has been fantastic!
I'm surprised I've never seen a video from you regarding a ground source heat pump. Given the quality of insulation standards you apply to your homes, to me it would make sense to install the most efficient HVAC system available. Granted, from what I've read about to ground temperatures in Texas, this would be the limiting factor on horizontal closed loops. But, the other loop systems seem feasible. I'm just curious if you've ever investigated a GSHP for your homes.
Matt, house looks great. You mentioned how all of your supply side is metal duct. Which in theory seems like a good idea, but it actually creates an acoustical issue. You can hear the air traveling through the ducts at the diffusers. Ran into this problem on a 4000sqft home. We ended up going back and cutting some straight pipe out and adding flex instead. This remedied the situation. Long island new york. Cheers
And just like that, Matt makes the only impeccably well constructed, well insulated, easy and efficient to heat and cool McMansion in the world. Though I do really like some of the interior design touches as well.
I first came across your videos in high school when I was looking into what materials to include in wall cross sections and what not. We all drafted the house we'd like to build some day and this house has pretty much the exact wall systems I designed back in sophomore year like 7 years ago this is awesome
I’m in HVAC/R So Cal. House looks amazing and Mitsubishi VRF is top of the line but that ductless head unit on the wall looks like an afterthought. All your beautiful finish work and that plastic thing slapped on the wall. I was a part of designing a VRF system that cost $250K for a house in Newport Beach and believe me there wasn’t a sign of the HVAC anywhere. You do great stuff.
I don't think the plastic will look as bad in a room full of exercise equipment. The client must think so too otherwise they would have gone another direction.
WOW. wish I was a close relative to the homeowners to have a first hand tour. The design of the equipment looks very pleasing and well formed. This house will no doubt be a very comfortable living space. Thanks for showing.
Matt: I’ve been watching you for years now and I’m going to build a new house in El Paso, Tx next year and will be using many of your tips,tricks and will be calling the company who built these HVAC systems from Austin..Thanks!!,
Nice house liked the boiler room where you had enough room to work instead of being a Chinese contortionist or playing Tetris with additional boilers and furnaces in the way. Keep it neat, as maintenance free as you can and always consider working in that environment yourself.
Besides the cook, maid and chauffeur living there, over the years an electrician, an HVAC technician and a plumber will move in. So that bonus room may come in handy. AND nothing gives them a better night's sleep as a dependable stream of boat payments coming in.
Nice system. I like the ultra aire. I recommend using 3/4 PVC caps on the drain. On a variable system it runs on extremely low cfm. You dont need to lose any air flow through the drain.
Beautiful home, and the exercise room is exactly what I want to do with my attic space. Great ideas, including the VRF hvac system to update my 1980s house.
I would love to see a manual J for one of these incredibly insulated homes. I don’t get to do many residential jobs anymore, but would love to see the mechanical needs when the home is built like this.
Ted Flick probably as long as a typical US home lasts, if you're lucky! All those sticks, staples, glue and OSB. We build like that in Europe too. When we need something to keep garden tools or chickens in.
For many HVAC systems without stages or variability they are very careful to match the capacity. This will tend to work well to dehumidify but will likely do it to much. During the winter in the North I have to run humidifiers for several months. In the south the system in the video is probably best. But for the north you'd probably also want a system that can reintroduce what it takes out of the air or if you want to be more careful with contaminants you'd need a whole separate humidifier. Indeed the system in the video is probably the best you could get for the south except maybe ground sourced heat pump. But those are quite pricey.
Check how low the static pressure is on that ducted head above the master bedroom. Check the manual for what filter is recommended. Awesome systems. I like the dehumidification, reduces the load on the system. Mitsubishi makes great equipment.
Videos like this - from a building science/IAQ perspective - always raise a question in my mind about the safety of the extensive use of insulation foams. By and large, I'd like to believe such a house wouldn't have issues, but I can't quite shake the question.
Best RTU I have ever seen was a Trane. Dont remember the model. No TXV, no Capacitors, no belts or pulleys, no grease, no panel screws. A rare unit for sure but it eliminates all the problems of standard systems. Direct drive, variable speed everything, I think a 7 ton system. As a unit hits the 10 year mark, they are usually filled with hacks and rigs and replacement parts, but this one will be spotless.
Beautiful house. Guessing that its 13R fire suppressed? I saw sprinklers. Would escutcheons with pop out heads. Can you do that with a 13R? Does the DC10 also help with off-gassing if a fire does happen? How does comfortboard compare to zip-R? Have you tried the cassette mini splits? Other things I like, your sound quality is better in these newer videos, as well as your cuts. This video specifically had really amazing cuts.
With so many builders using spray-foam today, imagine the future when all those homes have reached end of life and all that plastic refuses to return to the “dust” from which it came.
@@mothman-jz8ug Does he drive a Cadillac too? With amazing comfort and style? Did I tell you about "the killer garage?" No? Well how about this?: Did he tell you about the cheating bankers at the Federal Reserve and their inflation? And how they have cheated the middle class out of a 4-day workweek and defined benefit pension plan?
Looks like a great place for one of Trane/Mitsubishi's branch controller with energy recovery (I believe that's what they call them), an amazing little magic black box they install in the system where all the refrigerant lines come together. It allows heat to be pulled from one zone and delivered to another. I.E. If the basement calls for heating and the second floor is calling for cooling, the VRF branch controller knows to use the 2nd floor coil as a evaporator (removes heat from the space), and the basement coil as a condenser (adds heat to the space) without having to do energy transfer with outside. Also, I think they are making water heaters now that tie into VRF systems so that instead of dumping excess heat outside, you can dump it into a water heater (very similar to a heat pump water heater). I believe these things even come large enough to heat pools. It's not the cheapest tech, but its an awesome way to be energy efficient. Also, I notice quite a bit of critique in the comments regarding the rigid duct. In my opinion i think the rigid duct is essential. The units installed only can deliver up to 0.5" ESP at full airflow. If all the duct was all flex-duct, its possible that there would be friction losses in the duct that the design airflow may not be met. Furthermore, part of having an efficient design is making the whole system efficient, including the duct work. Generally speaking, every foot of flex-duct straight has the same friction losses as six feet of rigid duct of the same size (thus rigid is on the order of 6 times more efficient than flex, though admittedly duct work a much smaller piece of the efficiency pie than the equipment).
Work looks really good, only thing I would have done differently is not 90 the copper line's. Hopefully they didn't use couplings. Second job much better. Overall an amazing house, excellent work.
Great systems, beautifully done. The only problem I have is the handling of the condensate from that mini-split: pumping to a drain in the bathroom is a bit tacky (especially for a terrific house of that quality and obvious high price), and that pump/sump will probably eventually leak or overflow.
Lotta great work there. Both HVAC and interior detail. Wow! Look at that coffee machine. Boy, I would hope all that HVAC stuff keeps working till the owner moves out. Can you imagine an unknowing guy coming in for a repair?
Hate seeing all those unprotected threaded-rod hangers waiting to savage the unwary. How hard is it to cut them off short, screw on an acorn nut or both?
I really dig your videos. I know it’s not easy, but I think it would be nice if you included an approximated cost % premium for this type of system vs. conventional. You always sell me on the great building technologies, but I’d like to be able to compare cost to benefit.
Not sure about that perticular pump, but the pumps we use almost never fail with proper maint. and if they do the safety circuit cuts the system off before water damage is incurred, gravity drains on the other hand usually don't if and when they plug up.
@Wallace Naylor hot water baseboard. Almost no maintenance. The most efficient warmth. Hot air is cheap trash science, no science at all. And in the warm summer months? Open window.
@@comment6864 Open window? I'm going to assume you don't live in a humid environment... or are trolling. The house I'm living in has exactly what you say, and quite frankly, some nights I can't get to sleep because of how uncomfortably humid and hot it is. The boiler/radiator heat should be as you say, efficient and effective, but it does make some things more complicated, since radiators take up space and can't be blocked. Had to place furniture in places I wouldn't call ideal but it's not terrible. Still though, I'm going to have to rewire the upstairs to get a window A/C (as well as to ground the current circuits) running.
Rxonmymind the installation is the most important part of any hvac system. I usually do not agree with this gentleman he is poorly informed about building in high humidity areas. Spray foam adds nothing but expense and sometimes damage in the long run. I saw no ac ventsin the attic space and with variable speed systems you don’t need a dehumidifier system for the home but you do need it for attic spaces. I have a Trane xv20 and my humidity has never been above 47% and usually around 45%. Also this guy points to the merv 11 label and called it a merv 13. I would love to see the manufacturer that say it’s ok to put a merv 13 filter in their system. The money that’s saved from spray foam will be lost to added maintenance and premature evaporator coil failure. I do like the all metal ducts and the Trane and Mitsubishi equipment we are a diamond dealer in Mitsubishi and also sell a large percentage of Xv Trane products
All air contains heat and that is established science. as a HVAC contractor your sole purpose in your trade is to relocate heat and moisture from one space to another if you do not know this you may not be a HVAC tech. Maybe a plumber? Our systems do not cool anything they simply relocate heat. I do agree about the comfort of in my case in floor heat. We had a home about 30+ years ago that we rented. It had in floor heat best thing on a cold morning is a warm bathroom floor 😎
What a bunch of monstrous looking contraptions. If you really need cooling turn on a mini split for a while. Rest of the time just keep the windows open. Now that's joy.
Awesome home HVAC+D system. As a commercial HVAC Controls Engineer with a Mechanical Engineering degree and background in Commercial Mechanical HVAC design, this is a great setup! All it needs is a BAS (Building Automation System). That would link all the units and zones together into a single system. Maybe put a nice master touch screen control panel in a kitchen type area and maybe ever a web server so they can pull it up on their phones... The possibilities are limitless, lol. Glad to see a fresh air duct coming in from outside. Bringing it straight into the dehumidifier is really smart. How does the system know when to bring in fresh outside air? Is it monitoring CO2 (Carbon Dioxide) in the space or does it just come one when a kitchen or bathroom exhaust fan is running? With a house built this air tight, do you have to worry about venting pressure to the outside when the fresh air damper is open? Would love to see more videos showing modern home HVAC systems and all the new features that they have. The home HVAC market is really starting to catch up with what we see in hospitals and other large commercial buildings. Great video! Keep up the good work!
I was going to mention the same thing about Exhaust air. If you are bringing air in, You have some sort of exhaust for it. 20 years commercial service in the field here for a major HVAC manufacture.
Matt is right ... this is a very neat and well designed system and duct layout. Conditioned attic, in the south, is an energy saver. With energy costs going up, because of politics, any amount you can save on specking and installing a well made system will save tons of money. Humidity control is the most important element of a climate control system.
Trim tips and tricks before you hand the keys over. Would love to see the strategies you imploy to keep a complex trim package looking great through the years to come!
I may of missed it but wondering which system is conditioning the air in the attics. Also, I spent 40 years doing all types of fireplaces in the south. Those low slung ( I call them "TV fireplaces" because they are behind glass) units in any room need to be at eye level when you are seated. They look like an after thought with everything else going on around them and in a room with tall ceilings, a modern fplc. but traditional mantels. Love the split system with the condensate pump. I guess the tubing is accessible form the back side if there is a problem or maybe an auto shut off.
Light switch at attic entrance in beginning should always be mounted on opposite side of hinges. Talked to HVAC techs over the years and none of them would want a unit overloaded with electronics due to high cost of replacing various boards. Good luck getting a replacement electronic component after 8 to 10 years. Like the way they can vary the BTU output from 15 to 100%. Probably use a VFD to control speed. They are always obsolete after 10 years so you will need a new & improved drive that could require expensive or time consuming labor to program in all the many drive parameters. Had a customer that had 2 heat pumps that was backed up with natural gas. Company had to come out 3 seperate times first year under warranty and at least twice second year costing over $400. He finally listened to me and ran heat on natural gas all winter. His accountant wife some how figured it out that it was cheaper running natural gas for heat verses the energy saved from the heat pump aling with price of service calls. House had 2 by 6" exterior walls and 14" of attic insulation so even on cold days heat pumps did not run very long. Also at least years ago heat pumps always seemed to run air temperature out of duct work at least 25 degrees cooler then gas fired heaters. This was a problem with some humidifiers on heat pumps back then.
can you talk about the fire sprinkler system in a house. it seem like in the future most houses will have fire sprinklers and what can the average home owner or builder expect when dealing with them? does it require design or structural changes?
@@MW-gh1mo while im not a fire engineer i am a journeyman fire sprinkler fitter. for the most part i would say houses are less prone to fires now. but with new sprinkler system technology such as CPVC, the cost to install one has significantly dropped. it may only be 2%-3% of the entire budget
Is there an ERV that you didn't show or some sort of similar/substitute mechanical? Or, are those reserved for cold climates and not used in the South as they are up here in this part of the country?
Nice set up. Here in California we refer to it as "outside air" and shy away from the term "fresh air" considering the air outside is not always "fresh" and if I can be picky, it's not "freon" or R22, it's most likely R410A or "puron" if you want to use the brand name.
A video talking about the cost differences involved in building high performance homes vs standard homes is. I come from an area where you can have a 2000 sq ft home built for under $100 grand, but its all traditional, square, simple and certainly not high performance. I wonder what the same home with a proper HVAC, tight envelope, conditioned crawl space/attic would cost. Simple walls, no fancy finish carpentry, standard off the shelf kitchen etc just as economical as possible. Is high performance just for luxury homes or can it be viable for the low income market?
Neat video, but could we get a video about best use case, from mini-split, to basement/utility room HVAC, to ceiling placed HVAC, and maybe some others? That would be a big help, thanks. Also, theoretically, if I wanted to install HVAC in an old 2 story farmhouse/craftsman home, what would be the best approach (and duct types/sizes/locations for vents)? What would be the cheapest approach one could reasonably not waste money doing?
Nice house Matt. You're builds are trending well into the high end projects. What would you recommend for an average Joe like me building a 2200 sqft single story home?
For a "killer HVAC system", radiant heating floors plus radiant cooling ceilings are the way to go. They are virtually silent since no air is moved around, and more efficient since you can use a lower temperature differential - that matters a lot for cooling. You still need a ventilation system for indoor air quality, the most efficient ones use a radiant wheel to recover both heat and humidity. We have lived in our house with a system like this for more than a decade now, would not consider anything else if building a new house. Ultimate in comfort and minimum heating/cooling bills - a fraction of what the neighbours pay.
I’m just not one for houses such as this one costs. Of course we live in America and if someone works hard for one and earns it then great job. I’m one for a modest home with single floor and just enough room to be comfortable. 1500-1800 is perfect for me.
Don't be so sure they "worked" any harder than you did in life. I know lots of "old money" folks on the east coast who have never worked at all ... they live off the investments made by their family 2 or 3 generations ago.
In the long haul of things that over-priced house is an investment. If it's just a small family though, 1500-1800 sq. ft. is better all day everyday-- both for the carbon footprint and cleanliness of the home.
Lottery winner for sure, Wow what a house. I used to work in alot of high end homes around the Houston area. I would always leave stunned. How the 1 %ers live just blows my mind. Worked in one home, the duct work was big enough to walk in. One house had 8 Condensers, his electric bill was around 4 to 5 thousand a month, his house note was 14,000 a month. Peanuts when your making 11 million a year, after taxes.
Matt: Since the house is well insulated and sealed from inflation & exfiltration, where is the fresh air exchanger? If a bathroom fan, kitchen range hood and all is turned on, how does it exhaust that air then exchange that for fresh air intake? Just curious. Nice country palace.

After the improvements in attic it’s 72F on the top floor & 70F in basement. No room for whole homer dehumidifier so use portable 60 pint dehumidifier next to blower in basement.
My home is wonderfully pleasant now in the entirety of the home.

I am so very pleased I did it though as I now have the most comfortable home in our entire community that was built by Ryan Homes in 2002.

Hope you can help me OFFSHOREAIR. The critics I see above worried me as I was leaning towards MITSUBISHI ELECTRIC TRANE HVAC. The fella above said he's replaced several units like this. Now I am confused what is best AC manufacturer to focus on.
Trane Mitsubishi is the best
@@cahoonm I dont care for trane due to the parts cost, carrier/goodman have a 10 year warranty. They all have their problems, I like Copeland compressors, trane does make a really good compressor, owning a trane is like having a Mercedes parts are expensive after the warranty ends. I'm a service technician and I used to install for a company so I've seen them all break down. Stay away from rheem-Rudd they suck
@@C.dieslevonankwek7 you must be new to the trade. 90 percent of all the parts in trane, carrier, goodman, are all the same. Parts for trane are no more expensive than others. Infact, trane parts are easier to get than most carrier parts.
I did a somewhat similar system in my house - 3 zones with the Ultra-Aire. Struggled with it all for 10 years, ripped it all out and put in 6 one ton Gree Sapphire Ductless Minis. Fabulous improvement in comfort, control and cost.
Human Person thanks for the info I’m looking for atleast a 4 split system and those gree sapphire systems are priced Crazy good
@@Floreypottery
For what it's worth, because of my age and the humidity of North Carolina, I decided on separate one ton systems. I wanted redundancy for when a system goes down. And I wanted the ability to swap parts. Clean the filters monthly, always use X-Fan with Dry Mode. The Gree+ app works quite well on the Sapphires. They probably have a B series (2nd iteration) by now and I'd inquire about that. Zero complaints though you must carefully make your own template for locating the units and its screws. Use more screws for the brackets especially up top.
Oh yes, and most importantly any one of the Gree Sapphires dumps more water out of the house than the large central Ultra-Aire. The ultra aire is a hot air heater so you are stupidly adding heat to your house. The Gree Sapphires just run a low fan without the heat. Pipe carefully.
Wow, it seems like no expense was spared in this house, its perfect. Must be really cool to be able to collaborate with Matt to build a dream home.
Very good detailed information. So refreshing to see a builder actually install havoc systems that will keep the home owner comfortable in all seasons in all area’s of the home. I’m 18years in the hvac industry (mid-west) and more often than not the hvac systems builders installed were the cheapest most basic equipment with poor design, sizing and airflow. Just because you can’t see it doesn’t mean it’s not one of the most important investments in your home.
That trim work is amazing. I do commercial large scale building automation, this residential work is starting to resemble what you’d find in a hospital for their HVAC
It’s hard to just talk about the AC in a house that beautiful thanks for the info... but please revisit the house, it would be nice just to see the craftsmanship thank you!!
Matt: I was an HVAC tech for over 45 years with the last 15 spent as a contractor and I must say that this is one of the most beautiful systems that I've ever seen. I've done both residential and commercial over the years (mostly commercial) and I'm really impressed. I've been retired for about 15 years and I can't believe the changes in technology. Well done.
Matt: Please do a finish house tour if the customer permits. That looks like an amazing home.
yes please
It is a beautiful home. I'm in the planning stages of building and I'm turn between a French country and a Tuscan style.

I feel your pain.😄
Laying out a floor plan I like to help me decide..I hope.
It's ugly af, especially the outside. Looks like a gaudy McMansion.
You paid for that design?
I like when you have the designers over to cohost the episode. Nice to give the credits to the architects and mechanicals.
Beg to differ as a HVAC I am screaming at the nightmare maintenance of these monstrosity. Lazy ass homeowners will never change those filters, way to many systems to track where everything goes to what part of the house. Way too complicated for a homeowners, this will be the house all the companies will avoid.
I just built a house in Austin and used a VRF system and it ROCKS!
Great job Matt. Your finish carpenter is awesome
Dream home. Multi generational family home. Love it.
In 2008, had to replace our first floor furnace & compressor for a 2,800 sq.ft. typical NJ colonial built in '82. After some research I ended up with a Ruud/Rheem Comfort Modulating Furnace/Compressor combo. At that time, not many wanted to touch this product. The guy who installed it for me basically was the kind who could learn something new in 15 minutes (super-smart, not over-smart). He kept saying I was nuts to want to go with something so new and different. On the heating end, the furnace could modulate heat between 5-100% and the fan speed between 10-100%. Cannot remember the cooling ranges. Super happy with the decision to go with a modulating system. The house was always super comfortable with almost no hot or cold spots and my energy bills dropped by close to 40% (not just because of a new unit). In 2005, when it was time to replace the upstairs one, did the same!
Nice to see a high efficiency heat peat pump/AC installation similar to what I installed. "Yes" - these units are efficient for heating down to about 0 deg. F. - which was a big plus for our remodel in the Northwest (winters usually get down to only about to mid 20's F west of the Cascades - so plenty of margin for heat-pump-only heating in the winter). I wish I had the choice of using the Mitsubishi, but I think that one wasn't quite on the market at that time (or something like that). Lennox had a competing unit, but I didn't want a washing machine-shaped outdoor unit in my front yard. I went with the Daikin SkyAir, with a quiet outdoor unit that could hidden behind a bush - that system has been fantastic!
7:54 "I've got a great envelope- " and that guy has an amazing mullet.
I'm surprised I've never seen a video from you regarding a ground source heat pump. Given the quality of insulation standards you apply to your homes, to me it would make sense to install the most efficient HVAC system available. Granted, from what I've read about to ground temperatures in Texas, this would be the limiting factor on horizontal closed loops. But, the other loop systems seem feasible. I'm just curious if you've ever investigated a GSHP for your homes.
Matt, house looks great. You mentioned how all of your supply side is metal duct. Which in theory seems like a good idea, but it actually creates an acoustical issue. You can hear the air traveling through the ducts at the diffusers. Ran into this problem on a 4000sqft home. We ended up going back and cutting some straight pipe out and adding flex instead. This remedied the situation. Long island new york. Cheers
And just like that, Matt makes the only impeccably well constructed, well insulated, easy and efficient to heat and cool McMansion in the world. Though I do really like some of the interior design touches as well.
One beautifully set up home. But with 5 separate zones must have someone hired just to manage it all 👍. Great content
I first came across your videos in high school when I was looking into what materials to include in wall cross sections and what not. We all drafted the house we'd like to build some day and this house has pretty much the exact wall systems I designed back in sophomore year like 7 years ago this is awesome
I’m in HVAC/R So Cal. House looks amazing and Mitsubishi VRF is top of the line but that ductless head unit on the wall looks like an afterthought. All your beautiful finish work and that plastic thing slapped on the wall. I was a part of designing a VRF system that cost $250K for a house in Newport Beach and believe me there wasn’t a sign of the HVAC anywhere. You do great stuff.
I don't think the plastic will look as bad in a room full of exercise equipment. The client must think so too otherwise they would have gone another direction.
We place these systems in those areas 👍🏼 oasis air. They aren’t cheap
Just put a mitsubishi hyper minisplit in my home. Wonderful machine. Wicked straight forward and quite good energy saving.
WOW. wish I was a close relative to the homeowners to have a first hand tour. The design of the equipment looks very pleasing and well formed. This house will no doubt be a very comfortable living space. Thanks for showing.
Matt: I’ve been watching you for years now and I’m going to build a new house in El Paso, Tx next year and will be using many of your tips,tricks and will be calling the company who built these HVAC systems from Austin..Thanks!!,
ABSOLUTELY GORGEOUS INTERIOR WORK.
Nice house liked the boiler room where you had enough room to work instead of being a Chinese contortionist or playing Tetris with additional boilers and furnaces in the way.
Keep it neat, as maintenance free as you can and always consider working in that environment yourself.
Besides the cook, maid and chauffeur living there, over the years an electrician, an HVAC technician and a plumber will move in. So that bonus room may come in handy.
AND nothing gives them a better night's sleep as a dependable stream of boat payments coming in.
Yes. Is he nauseating or is it just me?
Nice system. I like the ultra aire. I recommend using 3/4 PVC caps on the drain. On a variable system it runs on extremely low cfm. You dont need to lose any air flow through the drain.
Beautiful home, and the exercise room is exactly what I want to do with my attic space. Great ideas, including the VRF hvac system to update my 1980s house.
Nice job with foam and unit being in condition space. Great building technology
Matt, I like reading the comments on your channel, because everyone is an expert!
Boy that’s for sure.
Matt is a real pluss for repair contractors
I would love to see a manual J for one of these incredibly insulated homes. I don’t get to do many residential jobs anymore, but would love to see the mechanical needs when the home is built like this.
This is a once in a lifetime project. I'm so impressed.
Ted Flick probably as long as a typical US home lasts, if you're lucky! All those sticks, staples, glue and OSB. We build like that in Europe too. When we need something to keep garden tools or chickens in.
For many HVAC systems without stages or variability they are very careful to match the capacity. This will tend to work well to dehumidify but will likely do it to much. During the winter in the North I have to run humidifiers for several months. In the south the system in the video is probably best. But for the north you'd probably also want a system that can reintroduce what it takes out of the air or if you want to be more careful with contaminants you'd need a whole separate humidifier.
Indeed the system in the video is probably the best you could get for the south except maybe ground sourced heat pump. But those are quite pricey.
Great looking house....
Love your videos... keep up the great work!
Well done positive energy! You too Matt.
Matt please do a public service & mentor youngsters they got to see a real builder in action. Love your videos
Check how low the static pressure is on that ducted head above the master bedroom. Check the manual for what filter is recommended. Awesome systems. I like the dehumidification, reduces the load on the system. Mitsubishi makes great equipment.
Videos like this - from a building science/IAQ perspective - always raise a question in my mind about the safety of the extensive use of insulation foams. By and large, I'd like to believe such a house wouldn't have issues, but I can't quite shake the question.
Plastic 👍
Best RTU I have ever seen was a Trane. Dont remember the model. No TXV, no Capacitors, no belts or pulleys, no grease, no panel screws. A rare unit for sure but it eliminates all the problems of standard systems. Direct drive, variable speed everything, I think a 7 ton system. As a unit hits the 10 year mark, they are usually filled with hacks and rigs and replacement parts, but this one will be spotless.
Great job Matt. Does the HVACD have a heat recovery component to help make hot water which will also make the VRF system more efficient?
Beautiful house. Guessing that its 13R fire suppressed? I saw sprinklers. Would escutcheons with pop out heads. Can you do that with a 13R?
Does the DC10 also help with off-gassing if a fire does happen?
How does comfortboard compare to zip-R?
Have you tried the cassette mini splits?
Other things I like, your sound quality is better in these newer videos, as well as your cuts. This video specifically had really amazing cuts.
What kind of controller on the wall do you have that will call for fresh air? Is that just a built in feature of the Ultra-aire humidistat?
With so many builders using spray-foam today, imagine the future when all those homes have reached end of life and all that plastic refuses to return to the “dust” from which it came.
Depending on the foam, there will be some solvent that will return it to liquid.
"Great Stuff" aerosol can foam goes to liquid if exposed to methanol.
It must be a nightmare trying to locate that inevitable slow roof leak.
@@fhuber7507 Sounds like using a bunch of methanol is also an environmental hurdle.
Then I suppose we should build homes to last and not be replaced so often.
@@mod8179 I agree, but building that way often costs more, and most builders and buyers don't want to pay more.
Matt, why not put a ceiling flush mount split unit rather than the wall mount. They fit perfectly between 2ft OC trusses.
Always informative and to the point. Thanks for making some of the best videos on youtube.
Good video even tho its way beyond my needs i picked up several elements that were applicable to my more ‘comfort fit’ home 🏡 - thanks matt!

Did I tell you about "the killer garage?" No?
Well how about this?:
Did he tell you about the cheating bankers at the Federal Reserve and their inflation? And how they have cheated the middle class out of a 4-day workweek and defined benefit pension plan?
Why didn’t you show the condenser??
I was actually looking at the video JUST to see the condenser, especially after Mat said it is a Mitsubishi - Trane venture. I was sooooo curious!
Looks like a great place for one of Trane/Mitsubishi's branch controller with energy recovery (I believe that's what they call them), an amazing little magic black box they install in the system where all the refrigerant lines come together. It allows heat to be pulled from one zone and delivered to another. I.E. If the basement calls for heating and the second floor is calling for cooling, the VRF branch controller knows to use the 2nd floor coil as a evaporator (removes heat from the space), and the basement coil as a condenser (adds heat to the space) without having to do energy transfer with outside. Also, I think they are making water heaters now that tie into VRF systems so that instead of dumping excess heat outside, you can dump it into a water heater (very similar to a heat pump water heater). I believe these things even come large enough to heat pools. It's not the cheapest tech, but its an awesome way to be energy efficient.
Also, I notice quite a bit of critique in the comments regarding the rigid duct. In my opinion i think the rigid duct is essential. The units installed only can deliver up to 0.5" ESP at full airflow. If all the duct was all flex-duct, its possible that there would be friction losses in the duct that the design airflow may not be met. Furthermore, part of having an efficient design is making the whole system efficient, including the duct work. Generally speaking, every foot of flex-duct straight has the same friction losses as six feet of rigid duct of the same size (thus rigid is on the order of 6 times more efficient than flex, though admittedly duct work a much smaller piece of the efficiency pie than the equipment).
Work looks really good, only thing I would have done differently is not 90 the copper line's. Hopefully they didn't use couplings. Second job much better. Overall an amazing house, excellent work.
Great systems, beautifully done. The only problem I have is the handling of the condensate from that mini-split: pumping to a drain in the bathroom is a bit tacky (especially for a terrific house of that quality and obvious high price), and that pump/sump will probably eventually leak or overflow.
How does that spray foam work when it comes time to redoing the roof? Just rip up and put right back over without any worries?
You just rip the tiles off and then put the new tiles on.
@@sprockkets we don't have tiles in these here parts of the country.
Lotta great work there. Both HVAC and interior detail. Wow! Look at that coffee machine. Boy, I would hope all that HVAC stuff keeps working till the owner moves out. Can you imagine an unknowing guy coming in for a repair?
Hate seeing all those unprotected threaded-rod hangers waiting to savage the unwary. How hard is it to cut them off short, screw on an acorn nut or both?
I really dig your videos. I know it’s not easy, but I think it would be nice if you included an approximated cost % premium for this type of system vs. conventional. You always sell me on the great building technologies, but I’d like to be able to compare cost to benefit.
I hope when that pump fails(and it will) it doesn't ruin that TV. Gravity drains are best!
Njy5435 true they don’t break down as often but sometimes especially with mini splits there is not a direct enough line for a gravity drain
Not sure about that perticular pump, but the pumps we use almost never fail with proper maint. and if they do the safety circuit cuts the system off before water damage is incurred, gravity drains on the other hand usually don't if and when they plug up.
Mini splits can leak for various reasons and that TV is toast when it does.
Living in Georgia I see those things fell with high humidity around here and mold and what not
His HVAC space is larger than my entire house . Love rich people !
Wow that is a huge system. Beautiful basement
What is the best?
One that is installed correctly. Buy the company not the system as 90% is the installation.
Nice video.
@Wallace Naylor hot water baseboard. Almost no maintenance. The most efficient warmth. Hot air is cheap trash science, no science at all. And in the warm summer months? Open window.
@@comment6864 Open window? I'm going to assume you don't live in a humid environment... or are trolling. The house I'm living in has exactly what you say, and quite frankly, some nights I can't get to sleep because of how uncomfortably humid and hot it is. The boiler/radiator heat should be as you say, efficient and effective, but it does make some things more complicated, since radiators take up space and can't be blocked. Had to place furniture in places I wouldn't call ideal but it's not terrible.
Still though, I'm going to have to rewire the upstairs to get a window A/C (as well as to ground the current circuits) running.
Rxonmymind the installation is the most important part of any hvac system.
I usually do not agree with this gentleman he is poorly informed about building in high humidity areas. Spray foam adds nothing but expense and sometimes damage in the long run.
I saw no ac ventsin the attic space and with variable speed systems you don’t need a dehumidifier system for the home but you do need it for attic spaces. I have a Trane xv20 and my humidity has never been above 47% and usually around 45%.
Also this guy points to the merv 11 label and called it a merv 13.
I would love to see the manufacturer that say it’s ok to put a merv 13 filter in their system.
The money that’s saved from spray foam will be lost to added maintenance and premature evaporator coil failure. I do like the all metal ducts and the Trane and Mitsubishi equipment we are a diamond dealer in Mitsubishi and also sell a large percentage of Xv Trane products
Just curious what’s the CFM rating on the filter box with the merv 11 filter?
All air contains heat and that is established science. as a HVAC contractor your sole purpose in your trade is to relocate heat and moisture from one space to another if you do not know this you may not be a HVAC tech. Maybe a plumber? Our systems do not cool anything they simply relocate heat.
I do agree about the comfort of in my case in floor heat. We had a home about 30+ years ago that we rented. It had in floor heat best thing on a cold morning is a warm bathroom floor 😎
What a bunch of monstrous looking contraptions. If you really need cooling turn on a mini split for a while. Rest of the time just keep the windows open. Now that's joy.
Awesome home HVAC+D system. As a commercial HVAC Controls Engineer with a Mechanical Engineering degree and background in Commercial Mechanical HVAC design, this is a great setup! All it needs is a BAS (Building Automation System). That would link all the units and zones together into a single system. Maybe put a nice master touch screen control panel in a kitchen type area and maybe ever a web server so they can pull it up on their phones... The possibilities are limitless, lol.
Glad to see a fresh air duct coming in from outside. Bringing it straight into the dehumidifier is really smart. How does the system know when to bring in fresh outside air? Is it monitoring CO2 (Carbon Dioxide) in the space or does it just come one when a kitchen or bathroom exhaust fan is running?
With a house built this air tight, do you have to worry about venting pressure to the outside when the fresh air damper is open?
Would love to see more videos showing modern home HVAC systems and all the new features that they have. The home HVAC market is really starting to catch up with what we see in hospitals and other large commercial buildings.
Great video! Keep up the good work!
I was going to mention the same thing about Exhaust air. If you are bringing air in, You have some sort of exhaust for it. 20 years commercial service in the field here for a major HVAC manufacture.
That house beautiful bro you do good work.
Matt is right ... this is a very neat and well designed system and duct layout. Conditioned attic, in the south, is an energy saver. With energy costs going up, because of politics, any amount you can save on specking and installing a well made system will save tons of money. Humidity control is the most important element of a climate control system.
We place these units in and they are a beauty. They need to focus on the details. Make them look nice 👍🏼
Trim tips and tricks before you hand the keys over. Would love to see the strategies you imploy to keep a complex trim package looking great through the years to come!
Love what your about Matt!
I may of missed it but wondering which system is conditioning the air in the attics. Also, I spent 40 years doing all types of fireplaces in the south. Those low slung ( I call them "TV fireplaces" because they are behind glass) units in any room need to be at eye level when you are seated. They look like an after thought with everything else going on around them and in a room with tall ceilings, a modern fplc. but traditional mantels. Love the split system with the condensate pump. I guess the tubing is accessible form the back side if there is a problem or maybe an auto shut off.
Light switch at attic entrance in beginning should always be mounted on opposite side of hinges. Talked to HVAC techs over the years and none of them would want a unit overloaded with electronics due to high cost of replacing various boards. Good luck getting a replacement electronic component after 8 to 10 years. Like the way they can vary the BTU output from 15 to 100%. Probably use a VFD to control speed. They are always obsolete after 10 years so you will need a new & improved drive that could require expensive or time consuming labor to program in all the many drive parameters. Had a customer that had 2 heat pumps that was backed up with natural gas. Company had to come out 3 seperate times first year under warranty and at least twice second year costing over $400. He finally listened to me and ran heat on natural gas all winter. His accountant wife some how figured it out that it was cheaper running natural gas for heat verses the energy saved from the heat pump aling with price of service calls. House had 2 by 6" exterior walls and 14" of attic insulation so even on cold days heat pumps did not run very long. Also at least years ago heat pumps always seemed to run air temperature out of duct work at least 25 degrees cooler then gas fired heaters. This was a problem with some humidifiers on heat pumps back then.
can you talk about the fire sprinkler system in a house. it seem like in the future most houses will have fire sprinklers and what can the average home owner or builder expect when dealing with them? does it require design or structural changes?
Why would houses need to be sprinklered? are they more prone to catch fire now than in the past?
@@MW-gh1mo while im not a fire engineer i am a journeyman fire sprinkler fitter.
for the most part i would say houses are less prone to fires now. but with new sprinkler system technology such as CPVC, the cost to install one has significantly dropped.
it may only be 2%-3% of the entire budget
Did you do all on 1 condenser if so did you use a branch box and if not why?
I love how you just make stuff up and then correct it. Funny. DC10 etc
Wow that's a dream system!! Great review man
It’s a nightmare that you won’t wake up from
Most homeowners take the hvac for granted. It is the heart and soul of a home. You can do without a lot of things. Hvac isn't one of them.
Nice video. What's the outside of the house look like? Condenser farm?
Thats a beautiful house. Great work.
I saw a house being built with the Zip System. Made me think of your channel.
Where was the condenser??? Show us the entire system.
Is there an ERV that you didn't show or some sort of similar/substitute mechanical? Or, are those reserved for cold climates and not used in the South as they are up here in this part of the country?
The D system ( dehumidifier ) also can act as an HRV/ERV. Wired in a few
Nice set up. Here in California we refer to it as "outside air" and shy away from the term "fresh air" considering the air outside is not always "fresh"
and if I can be picky, it's not "freon" or R22, it's most likely R410A or "puron" if you want to use the brand name.
Should just say refrigerant
@@RyanRiopel yep👍
A video talking about the cost differences involved in building high performance homes vs standard homes is.
I come from an area where you can have a 2000 sq ft home built for under $100 grand, but its all traditional, square, simple and certainly not high performance.
I wonder what the same home with a proper HVAC, tight envelope, conditioned crawl space/attic would cost. Simple walls, no fancy finish carpentry, standard off the shelf kitchen etc just as economical as possible.
Is high performance just for luxury homes or can it be viable for the low income market?
2,000 SF / $100k = $50 / SF. No builder builds a house for that.
@@plowboy5220 he never said where he was from, and you're speaking for the whole world?
Great job. Great information for the newbie.
Neat video, but could we get a video about best use case, from mini-split, to basement/utility room HVAC, to ceiling placed HVAC, and maybe some others? That would be a big help, thanks.
Also, theoretically, if I wanted to install HVAC in an old 2 story farmhouse/craftsman home, what would be the best approach (and duct types/sizes/locations for vents)? What would be the cheapest approach one could reasonably not waste money doing?
Nice house Matt. You're builds are trending well into the high end projects. What would you recommend for an average Joe like me building a 2200 sqft single story home?
For a "killer HVAC system", radiant heating floors plus radiant cooling ceilings are the way to go. They are virtually silent since no air is moved around, and more efficient since you can use a lower temperature differential - that matters a lot for cooling. You still need a ventilation system for indoor air quality, the most efficient ones use a radiant wheel to recover both heat and humidity. We have lived in our house with a system like this for more than a decade now, would not consider anything else if building a new house. Ultimate in comfort and minimum heating/cooling bills - a fraction of what the neighbours pay.
Hey Matt, I'd love to hear what you think about adding UV lights to the HVAC system for indoor air quality.
DIY & Outdoors the HVAC installers will take your money all day long for that gimmick!
Matt! How would you feel about taking a crack at a steel frame/shipping container combo home in florida?
i love these mitsubishi systems they are super solid.
I’m just not one for houses such as this one costs. Of course we live in America and if someone works hard for one and earns it then great job. I’m one for a modest home with single floor and just enough room to be comfortable. 1500-1800 is perfect for me.
Don't be so sure they "worked" any harder than you did in life. I know lots of "old money" folks on the east coast who have never worked at all ... they live off the investments made by their family 2 or 3 generations ago.
In the long haul of things that over-priced house is an investment. If it's just a small family though, 1500-1800 sq. ft. is better all day everyday-- both for the carbon footprint and cleanliness of the home.
@@DW-vl2wi Not to mention maintenance costs and general updating needed every 10 to 15 years....
How many millions does this house cost?
Lottery winner for sure, Wow what a house. I used to work in alot of high end homes around the Houston area. I would always leave stunned. How the 1 %ers live just blows my mind. Worked in one home, the duct work was big enough to walk in. One house had 8 Condensers, his electric bill was around 4 to 5 thousand a month, his house note was 14,000 a month. Peanuts when your making 11 million a year, after taxes.
Matt: Since the house is well insulated and sealed from inflation & exfiltration, where is the fresh air exchanger? If a bathroom fan, kitchen range hood and all is turned on, how does it exhaust that air then exchange that for fresh air intake? Just curious. Nice country palace.
