Great job with video. I like seeing your thought process in terms of the esthetics of locations. Not seeing the units when first walking into the room. Height considerations etc. Thanks
Thank you Carter, glad you enjoyed it!
That’s the problem with mini splits who wants to look at one of those things in every room
Love mini splits
Great video
Going forward I would recommend leaving 3’ of clearance in front of the electrical disconnect per the NEC
Hi guys! , from Paul at your local Chevy dealer. This is a great video.
Hey Paul! Thanks for watching!
Great vid, thanks.
My property in the U.K could use something like this.
It’s all electric with 1970’s electric warm air heating using in wall ducting.
Had a quote for £13k for a ducted Aircon install and around £7k for a 10kw multi split ductless like in the vid.
Great video. Very informative.
Thanks for watching.
Hey Paul! We love seeing full-home installations. You did a great job. Perhaps you'd be interested in trying the Cooper&Hunter brand next time? Our Hyper Heat units offer energy-efficient heating in ambient temps as low as -22°F.
I'd be interested in learning about them. Am looking at putting these in my home to replace a forced air system - outside of chicago.
I love Cooper and Hunter!!! I've got 4 systems from you guys and love all of them. Super reliable and whenever I install minisplits for clients on the side I always offer CH.
Hi Paul, I’ve got a clogged pipe that needs some fixing. 🤣🤣🤣
Anyway, beautifully done! Just find it weird that mini splits have only recently taken off in US, we’ve had inverter/variable speed air conditioners (splits, floor standing, and window ACs) here in Asia for decades.
Anyway, I’m glad it’s taking off and Americans are enjoying the quiet and energy efficient ACs
I'm glad too! We love the mini splits. Thanks for watching!
on demand water heaters are only sort of catching on with a specific group of consumers, likely made up of those of us who've learned whilst roaming this beautiful world and now have a spray hose by the toilet, on demand water heating and mini splits as well as a dismay for the lack of functional furniture but that may be the area I find myself. At any rate I owe a debt of gratitude for all I learned outside the walls of the US 🤔🤨😮💨😵💫☹😡😡😡☠👹😡🤬😭😭🥺😏🙂
NIce video, thanks!
Great video
Thank you!
Nice job!
Thanks for watching!
Nice video, thanks
I think the mini-splits are the bomb but I also think they can be improved upon. No 1# is they would be better off with a sealed 134A bldc motor compressor with a stand-alone embedded controller that will run off a min of 72vdc so that it's easily able to run off a bank of six 12vdc 100Adeep cycle marine lead acids (which can be obtained new for only about $100 each). My current project is dual 134A compressor system running off such a bank (approx 3 ton) and I think just a 1000 Watt bldc controller can use an alternator re-purposed as a bldc motor to push a single 134A compressor (a Valeo) @ about 500 Watts no problem. (I'm currently using a PM DC but it only takes 12 amps @ 72vdc to drive both) I upgraded caps to 100v in four ubiquitous mpt 7210As and each pair of 300 watt Q-cells (about $65 each) series-ed together puts out 72vdc un-loaded which (coincidently enough) is what the charge controllers are designed to charge at. Their outputs can be paralleled too. Getting around the need for costly un-reliable up-converters for turning DC to AC is a big plus too. BLDC condenser and evap fans are as well, though I'm pretty sure most split units already come with one or the other. The systems I use (for bus vehicles) came with barrier hoses with O-ring fittings that only require band clamps engaged with a tool like pliers to apply. People need to take solar away from the government and all these opportunist contractors (that just want people to finance a costly installation) and get with the program. AC is the lions share of everybody's electric bill. Solar is nothing but using enough panels with charge controllers to charge batteries and keep them topped off as you run whatever you power off of them. Keep them charged and they will last just like in a vehicle. That's the key.
Thanks for the very well explained presentation...
All that I have seen with the ductless system, so far, have been retrofits; but I am yet to see a clean installation for a new project. Bearing that in mind, the mounting walls always seem to be exterior-walls-preferred.
In new construction, mounting on an interior partition could offer more flexibility; so my question is: Is a 3" PVC pipe located in a 3-5/8" stud wall sufficient to run all those lines from each a/c head? or can each of those lines just freely run in the walls uncovered by your slim duct? And lastly: If then running those lines under a slab-on-grade, what diameter PVC chase would you recommend as a minimum?
I suppose that with proper planning the condensate drain line could follow is own path, or even drain to indoor plumbing.
Hey Troy, thanks for watching. I am the opposite of you as I have basically no experience with new construction projects. All of the jobs I have designed have been new projects like this one, so unfortunately I don't have those answers for you.
There are mini splits made that work from Grid as well as DIRECT from solar so more efficient since no conversion of the Solar to AC power when solar power available and can use a smaller inverter usually.
True! but also cost more than twice as much! much cheaper to just put a large array and run it off of PV.
@@jmd1218 not necessarily especially if you are not doing it DIY.
Wow I could use that set up. 👏👏👍🤗
Hi Linda! We have the same last name!
This is a really good video. I'm currently restoring a 4200 ft2, mid 1800's home and I've dumpstered the entire HVAC system. The 1600 ft2 upstairs is 4 BR and 2 baths and will be used as a B&B. The rest of the time, it will sit empty, so I wanted to design it with a mini-split to give the occupants full control over their comfort. Well... that led me to wanting to do the same with the 2600 ft2 downstairs where I'll live. I'm looking at Daikin, Mitsubishi, and LG. What scares me is that I can't calculate my power consumption for a typical South Carolinia summer. How does a full, zoned mini-split system (with as many as 11 units) compare with a traditional duct heat pump system, assuming a very efficient condenser? I've seen your videos where the homeowner was installing solar collectors so can I assume it's gonna be low?
South Carolina Summers and Winters are very difficult to manage.. We are up n down all year.
How are the units working
Paul, Do you have a comment on using a mini split in about a 2400 square foot walkout basement that comprises a great room, game room that are adjacent, and then also two separate bedrooms with doors? Should I use one head in the open area and expect it to AC the whole area, or recommend using a separate head in each bedroom and game room and great room. Generally speaking the basement never feels warm in the summer because the upper level is fully centrally air conditioned, but it can get stuffy. I'm told that basements generally are well insulated and don't require as much cooling and heating if they are sealed up real well and don't have much air leakage. thanks.
You do the cooling the bathrooms that are joining the bedrooms or in the hallways
Hi , just Got a 3 zone multisplit system installed. Thank you for that guided tour on operating the units. Very educational .. I have a cape code in PA. 12k and 9k downstairs and 12k upstairs ,,My daughter is like a polar bear and likes it cool upsatairs..but It gets pretty warm upsairs during the day with the sun beating down on the roof. Question for you..I understand all 3 units need to be in the same mode. With all 3 units in auto /heat mode. how best can I keep downstairs comfortably warm while keeping upstairs cool enough for her during the day?...Thanks
Thanks for the super detailed walk through. I’m in MA and have been wanting to do a 5 zone install for a while now. Sick of window AC’s and dont have duct work for central air. I assume these run cheaper than a full central air conversion?
Yes the ductless option is typically more cost effective than adding duct work and installing a new condenser. It all depends on how many units you would need though.
Consider installing a couple of smaller 2 and 3 head units for several reasons. Smaller BTU units in same series are generally more efficient . Also if one unit has problems you still have AC with other unit till first one is fixed. For example Free brand in their Saphire line the single head units 9,000 but is 38 SEER the 12,000 BTU is 30.5 SEER the 18,000BTU is 24.5 SEER. These as well as some other mini splits maintain heating down to minus 22 Farenheight.
Same issue for me... I opted for a 18kbtu for the living room and pretty much cools my house easily, very quiet. You can feel the difference between this and a standard ac. I recommend it! I have a mid century modern him with a 3 1/2 ceiling
I think you can set the heat pump on a pad on the ground...nice demonstration
The heat pump can go on a pad, just has to be off the ground because on snow. We usually like it to be a foot off the ground. The splits design fits better on a stand as well. Thanks for watching!
Hey Paul, great videos. I have a small Cape in New England and I'm looking to do an installation of 5-6 heads. I was looking at ceiling cassettes, what has your experience been with these heads? Also, what do you think about running the refrigerant lines through the 2nd floor crawlspace/knee-wall area to get to different rooms in the house?
Hey Matthew, thanks for watching. I like the ceiling cassettes a lot. Mitsubishi makes a great ceiling cassette product that fits between 16" joists in your ceilings. Daikin has some nice options as well. Running line set through crawl spaces and areas like that are a great option and can make the installation a lot easier.
@@paultheplumber8665 Same here same here I really want one in my entire life!
Don’t use ceiling cassettes I’ve installed tons in Florida they’re terrible if they have a problem.
If you want a nice mini split go with lg art cool or traditional mini splits
Ductless system is the future, and the present. In USA a lot of people are still reluctant to these systems. I think with time, they will become more popular.
I'm not convinced that's true. The problem with mini splits is the lack of air purification and having to maintain each head.
In my opinion new systems like Rheia make a lot more sense. Still ducted but has a simpler install. Bonus is it has a high air mixture for comfort which traditional HVAC and mini splits don't offer.
Paul, How far away from the outdoor compressor can you install an indoor unit? We are wanting to install one in each of 2 containers 25' apart, and a 3rd unit in a shed. We'd have to bury about 25' of the connections in conduit.
Typically it is a range of 66' to 98'. It all depends on the outdoor unit. You shouldn't have any issues with 25'.
Paul, thanks for your video, enjoyed it. Question what is the Sq footage of this house? I'm looking at a Ductless system for a 2000 sq ft. What size would you recommend?
I don't remember exactly what the sq ft was here, but sizing the system all depends on placement of the heads, and the overall airflow of the house. I would have a licensed HVAC company come in and do measurements to help you with the system design. Thanks for watching!
I will be getting a 41,000 btu for my 1,200 square foot home. A little over kill for the home size,but ok.The central air that has duct work threw out the home is really picky about the ac/heat BTU size.Also get a dehumidifier.
@@gerald4027 I'm researching these now myself. I think an over sized unit can cause issues from what I have read. I know nothing about HVAC, so don't go by my limited knowledge.
@@timkr66.mrcool makes mini splits that is heat or cool.i am getting 2 units,each unit does 3 to 4 areas each.About $7000+installation and wiring. MrCool works when the weather is down to 10 degrees in the wintertime.
My return on investment will be immediate - have no AC And do not EVER want to go through a summer like last year! High heat and bad air. Thank you for this video. I am calling companies for bids and this has made me much more informed of options on placement of the head units. Aesthetics matter
Glad it helped, thanks for watching!
What are the concerns for heating in Missouri, on the few winter nights that get down to below 5 degrees. Do people keep they're old furnace for backup, or put in baseboard heat?
Yes mini splits are typically used as a supplemental source of heat. They still can perform to the -5 degrees nights with certain models, but it will use a lot of electricity.
Neat idea! An A/C and heat guy pitched this idea to me. And I have been thinking about it. So what about the bathrooms?
We try to design them so that there can be airflow into the bathroom, but typically there is no perfect solution for the bathrooms. It all depends on the house.
@@paultheplumber8665 Okay, thanks for getting back with me.
Exhaust fan in the bathroom, means conditioned air makes it way in.
This is great. Never thought a minisplit could cover a whole house. Question though: how are they heating/cooling/drying the bathrooms without having "heads" in them?
Thanks for watching! That is a great question. We do our best with the design to try and create air flow that can make it into the bathroom. However, the way houses are built there is typically no perfect solution for heating/cooling the bathroom (unless it is new construction or there is attic space above).
@@paultheplumber8665 that's something to think about. Thank you for getting back to me! Great video keep doing what you do 🙂
I'm in the process of completing my home building project, all metal barndominium in Alabama. We have hot summers. My bathrooms are fully insulated. My logic is they are not full time use areas. Therefore, I'm willing to sacrifice a little comfort of necessary. In the colder seasons I think I'll be happy with electric space heaters for the hour or so use daily. Also, heated mats and radiant floor heating are popular choices. Cooling can fairly well be accomplished with through wall ducts with fans if desired. I'm stepping out of the box for efficiency.
Paul do you install traditional condenser/air handler systems also?
Yes we do!
What's the average cost for a whole system just like this one?
Awesome
I like the idea of 'zone' AC, but I don't like the exterior aesthetics at all. Can these systems be installed with one vertical 'slim duct' and then fish the lines laterally to get to each of the room units?
Can you do this in a row home? I have radiators and widow air conditioning. Also what Is the range of cost
My furnace and air conditioner are each 19 years old and and need replacing. My house is older, so there are two bedrooms upstairs that do not have supply vents. I'm looking at installing a mini split system going to those two rooms on the second level instead of running ducts to those areas. What do you think about installing a whole house mini split system INSTEAD of replacing the furnace and air conditioner? I'm in central Iowa.
That's a tough one. While you already have ductwork in your house, it might make sense to just get a duct cleaning, and replace your current system with a super efficient heat pump (heating/cooling) and furnace combo. With the inverter heat pumps (I like bosch or amana), and a modulating furnace you'll get awesome efficiency and comfort. If it's not too difficult to run duct to the upstairs bedrooms I would go that route.
Wow ! Great install!! I,m guessing a 30 K + dollar figure ?
Thanks Will!
@Stephen James With a unit in each room you could do that. Without a head in each room it's possible but wouldn't guarantee it.
Great job can you tell me how much this cost ?
I’ve never seen this done for a whole house so it was really interesting, my only question is, what about the bathrooms? Is there enough air flow to condition them as well or do you have to install something separate for the bathrooms?
Hey Rachel, thanks for watching! We try to design the system to push as much air flow as we can to the bathrooms, it's rare we put a unit in the bathroom unless we are doing a concealed ducted unit in the attic.
Best design is to double the ASHRAE Recommendation for Bath Exhaust. If you think this will be a problem, when you are taking a Shower, put an Air Switch in the Shower, so you can turn the Fan on and off while taking a Shower.
I have the same question since my hot water heater,washer and dryer is in the auxiliary bathroom.average temp about 120°.
Gerald Nordahl why don’t you put a Heat Pump Water Heater in. That way you can cool the space, and heat your water. BTW If the heat is from a Gas or Fuel Oil. Water Heater you have a serious problem, and need to get a qualified HVAC or Plumber to check your system out, it sounds like you are getting a backdraft, down your flue, and are putting Carbon Monoxide in your space, if this is a gas or fuel oil water heater.
@@stevenmoomey2115.the water heater is electric and the dryer is electric. There is no gas in the room.a water heat pump makes heat to heat the water and it does not cool.
Enjoyed your video. Would you recommend the system as the sole source of heating?
Thank you! It depends on where you live. For the Northeast temperatures where we installed this system I would not recommend it for the sole source of heating.
look at Mitsubishi hyper heat mini split , Daikin is good only for Florida they are pathetic
@@andreycham4797 Hey Andrew! Thanks for watching. The Daikin Aurora actually heats down to the same temperature as the mitsubishi with very similar efficiency levels. We sell both Mitsu and Daikin, but don't recommend either for a sole source of heat in the Northeast climate.
@@paultheplumber8665 What could go wrong? Why do you not recomend that ?
@@andreycham4797 It ends up working too hard because it gets so cold up here. You'll spend more on electric than you would on supplementing the heat with your gas or oil system.
what do you offer for maintenance and service?
Very cool! How about bathrooms?
Thanks for watching! Bathrooms are tough because the space is generally too small. Sometimes we are able to put ceiling cassettes if there is attic space above.
Wow! Almost makes me want to flip for one...so difficult to find an honest contractor here in florida...every crook comes to sunshine...
Is there anything special one needs to do with new construction to accommodate these systems? I want to include one (or two) of them in an upcoming addition, and sure would love to conceal those massive lines inside the wall. Thanks!
New construction actually can make the installation a lot easier! You can hide the lineset, eliminate the need for slim duct (in most cases), and ceiling cassettes are a great option for new construction as well!
@@paultheplumber8665 Smart thinking. I'll run that by my contractor when the time comes!
Internal walls? The drains are tricky items to get right.
Im building a new house and thinking doing mini split units throughout the entire house as seen in this video. My question is what is the difference in cost? Whole House Mini Split vs. Traditional HVAC unit with ducts and air exchange in attic?
If the house is new construction it might not be that much more expensive than mini splits. I have much less experience in new construction as I do with existing homes though. I know with existing homes a lot of times mini splits are more cost effective, new construction it may not be.
You're in New England? My wife and I are designing a log home and we're contemplating a mini split as our main (and only) heating and cooling system.. instead of a ducted system. What are your thoughts on this?
Depends a lot on floors and room layout
We are in New England. New Hampshire more specifically. If you plan on living there year round I wouldn't rely on the mini-splits as your only source of heat. The electric bills running the heat pump full time in the winter would most likely out weigh the costs of using gas/oil heat. The reason it was a good option for this home is because they have solar panels.
Would this be a good add on for a boiler system. No central ac. Ranch house
Paul The Plumber we’ll also have a pellet stove and we’re likely going solar as well. We’re building in MA.
can outside line sets be hidden inside the stud cavities in new construction?
Yes they can!
How does it drain the condensate
The first condenser/heat pump is huge, but it can only support 4 rooms?
Correct, biggest one like that they make can support 5 rooms (they didn't make that at the time). Or there is an option for a taller unit that can support up to 8 heads, but you need branch boxes and other things to make it work.
Huge house
How much is the cost for a whole house 3 bedroom two story house?
Nice system, Paul where are you located am interested I live here in Rhode Island
Hey Erick, thanks for watching! We are located in New Hampshire so unfortunately RI is out of our service area.
I'm from New Jersey and I'm interested on Daikin heatpump minisplit, but my question is if I install that one in my house I won't need my furnace anymore?, I have a gas boiler, and what about the electricity bill?
@@hectorsanz6870 It's possible to use these as your only source of heat, but typically I don't recommend it if you live in a cold climate area. I would keep the boiler around for when it gets really cold, that will be more efficient than the electric heat.
How much does this entire system cost?
What happens if you run the heat pump with the unit installed on a patio stone instead of elevated?
Heat pumps need to be elevated to work effectively. Regular A/C condensers can be level on pads.
Wow sign me up. How is the cost compared to installing a new furnace and A/C unit?
Thanks for watching! The costs are very comparable if you need to add ductwork to the home. The ductless systems would be more expensive if you were just replacing an existing furnace/AC.
Paul The Plumber after this video I’ve had 6 units installed at several properties. I saw it as a great opportunity to create space. For instance I’m able to turn 1 bedroom units into 2 bedrooms by deleting my furnace and water heater. I go mini split and tankless in a closet. When stuff sells for $400+ a sqft that can make us some room!
@@SeanPGribbons That's awesome! Glad the video helped.
You said in the video that these heads can be used to heat these rooms. Tell us more about that.
The outdoor condenser is a heat pump, so it provides both heating and cooling.
Can all of the refrigerant lines be run via 1 pipe into the attic and then distributed to the units? (To prevent all of the pipes on the outer walls)
In some cases you can. That would typically require a branch box which only works on certain outdoor units.
Our system has all lines going into basement behind unit and then through walls to three head areas around house. Looks pretty clean.
how much for an install like this?
How is for one of those free units?
I wonder if Nest will ever partner with a mini split maker.
The exact thing I was wondering
Mr Cool mini splits can be controlled from your smart phone. Independent zones as well.
Not sure about nest but there are mini splits that can be controlled using echo dot/Alexis as well as other wireless wifi methods
If you want to expand in the future can you buy a 36k BTU Unit but only use two out of the 4 heads? Is it possible or do you have to use all 4 heads?
You can leave open spaces for future heads.
@@paultheplumber8665 Thanks! and thanks for the video! ... So if you only use a 9k indoor unit and a 36k outdoor but leave the other spaces open for future upgrade. It's not too big of a difference to have a 36k outdoor and only one single 9k indoor for a year or two until you add more indoor head units?
Around how much is for everything
Where to buy the outside covers? I bought a 3 head system ty
You can them from amazon or any HVac website. I noticed one thing that my mr cool cover discolored so quickly! It is not even a year old and I can see the cover changes from bright white to dull white with yellow hint to it.
The alternative way is to buy water down spout from any hardware store. Split it open and put on your line set. I found they look more attractive and durable at least they don’t discolor quickly like mini split covers do .
What was the cost - ballpark? Thanks!!
20,000
They "work to 100% efficiency down to 5 degrees" (as a winter heating solution). However, it looks like all of the interior units (cassettes?) are mounted near the ceiling, with the exception of the one in the child's bedroom upstairs. I see how this would work for A/C, but don't see how this would be efficient for heating. Since heat rises how does this heat the floors and lower areas of each room?
I think in some units there are two components for the blower that allows it to "aim" the outputted airflow.
The vanes can be adjusted to provide airflow where you want it.
So how do I get you (or anyone) to install one in my house? Do you have DIY training? In Northeastern Calif I'm about a 2-hour drive to anywhere.
We are in New Hampshire so unfortunately we can't help you with the install. I would recommend looking up a licensed HVAC company in your area to get quotes for the install. Thanks for watching!
Does any units have a dehumidifier?
Sure do. On cooling works a treat. Or the "dry" button
Can these specific models all run on auto at the same time?
Yes they can.
No they can’t. Heat or cool. Not both
How do the unconditioned rooms fair? Bathrooms and laundry and so forth?
They are perfect for rooms that you have a hard time heating and cooling. A lot of times when there are additions to a house we will install a mini split instead of adding more ductwork.
Paul The Plumber : I’m asking in instances where the whole house is done with a multiple mini split, how do the unconditional rooms, such as bathrooms and closet do? If there are only units in main areas do rooms like bathrooms have big fluctuations?
@@Bward216 You try your best to design it so that there can be airflow into those rooms, but any rooms that you don't have an actual unit in you'll have a hard time controlling temp.
Hot water is still on the furnace/boiler?
Yes, the water heater in this house is connected to the boiler.
How do you condition the air in bathrooms?
We try to place the units in places that will get to the bathroom as well, but you really can't guarantee airflow to places without a head in that area.
How do you condition air in bathrooms and hallways with the system they have? Assuming they’re using that for 100% of their conditioned air.
A lot of times there isn't a great solution for conditioning the bathrooms. For hallways it's generally just leaving doors open.
Only problem.. i believe you’ve surpassed the allowable vertical distance which is 49 feet and 25 ft between heads..
We did not, 2 different outdoor units. The system has been up and running for over a year now so they are good to go!
What type of timeline are you talking about for ROI on a project like this?
It depends on everyone's situation. With this homeowner having solar panels as well it will be a lot quicker because their gas and electric bill will be close to $0. Without the panels you're still looking at an electric payment and probably a fuel bill for when it gets super cold. the range depending on the situation could be 5-15 years.
How much did this job cost
QUESTION: If a freon leak develops in one of the freon linsets to one inside head, Does the whole system (all the head units) leak down on the same condenser unit? If only say one inside head is being used does the efficiency increase since you are using 1of4 or 1of3 (much less BTU s ) for the same surface area of condenser ?
The condensers have a minimum BTU output. If that minimum is 5000, and you're running one head, the minium BTU of that unit is 5000. If you have five heads running, each can run as low as 1000. (Depends on the unit, but that's the basic concept)
@@rykin thanks but didn't answer my questions.
@@teekay1785 If one has a freon leak, it does bork the whole system. Using one head doesn't mean it's more efficient than using four because the compressor can only run so slow and it's minium speed is divided among all of the heads running.
For many minis, the compressor can only run as low as 1/3 of the unit. For a 36k unit, if you're running one head, the compressor is still kicking out at least 12k BTU. If you're only running one head that only needs 9k, the system will short cycle because it's over running itself.
@@rykin ok thanks . I am aware that each head can only run so slow but there is also a much greater surface area of condenser per BTU with say one head running at 5,000 BTU than 3 running at 5,000 BTU so heat exchange with atmosphere should be more efficient . My impression is that even with regular split units with inverter compressors they are more efficient per BTU at lower BTU outputs. such as a 2 ton unit producing 12,000 BTU at their lower range versus at the sane unit at 16,000 BTU output even though the compressor is still matched to the output BTU the 12,000 is more efficient Generally.
Correct. This is the Achilles heel of these type air conditioner. So, make sure the pros installed it, torque the flares properly and at least 24hr pressure test
Ah, so you _can_ install multiple outdoor units for one building. I was wondering about that.
Yes you can, they make both single and multi zone units.
My only issue with mini splits is its inability to condition the air in bathrooms and walk in closets. Especially considering these two rooms both have humidity issues if the air isn't conditioned. The smallest head unit is too big for a bathroom and way overkill for a walk in closet. With central air these two rooms can simply have a small vent to take care of the issues.
That's a good point. I guess there must be a solution for that issue when you go ductless.
You can remedy this if the unit is positioned correctly. Otherwise the best bet is to use a ducted minisplit system for that bedroom that has multiple rooms.
How many rooms can u get out of a ductless air conditioner. I have a four bedrooms n a basement can I go ductless?
Yes you can. The max amount of indoor units you can install of one outdoor unit is 8.
*does split and lands on your lap*
what did cost ?
What was the investment? And where are you guys located? Thank you
I don't remember exactly how much this particular job was. Upwards of $15k. We are located in Derry, NH. Thanks for watching!
Thanks a lot
can I run all of these lines through walls and my attic? I don't want that chase running around my house
In some cases you can, it depends on how much space you have in your house to do so.
I need to heat my non finished basement is this suggested,I can do propane but I’m leaning more towards this.even thoug( I won’t need to AC basement
These are a great option for heating the basement and great for humidity control as well.
@@paultheplumber8665 thanks for your reply
Transfers the cooling lol
I'm kind of new to this but I really have a hard time believing that tossing in some Mini-splits and solar panels will create a home with almost no energy bills (Net Zero). I'd imagine a serious energy audit with spray foam air-sealing in every nook-and cranny would need to be done as well as a ton of air-sealing and fiber cellulose in the attic. If they have a serious commute that clipper-creek EVSE will suck up most of those electrons coming from the roof anyway.
I agree. I’ve been an electrical contractor or a long time and don’t see solar pushing this load without being interconnected to the grid
Lol did he say coolant runs through the line sets?
It's tough when the camera starts rolling!
What about venting and make up air? The reality is there is no return air like a regular forced air HVAC system and there is no fresh air make up correct ?
Regular furnaces usually have a flue system to exhaust the return air. Doesn’t this system need fresh make up air and return air to be exhausted ? Am I missing something here ?
There is no ducting so the air runs right through lines that feed directly into the indoor units. It's also a heat pump so the heat is generated from the condenser. Does not connect to any furnace.
Paul The Plumber So you would need some sort of venting system to go along with this for fresh air and exhausting stale air no ?
Old system in the house did not have central air (you see floor heaters in the vid) so nothing changes, open the windows for makeup air, my experience with houses here in US vs in EU is they are all super drafty/leaky, when it is windy, i can feel cold air entering, in EU with brick houses and XPS insulation on the wall and plastic windows it is pretty airtight, and those newer houses need makeup air badly (increased humidity that creates mold issue) but to keep efficiency high you have to use air to air exchanger in order to keep heat losses under check www.controlledair.net/blog/2013/september/why-an-air-exchanger-is-a-good-choice-for-your-h/
These don't have anything fresh air no. But add a "Smart Vent" or similar, and Bob's your uncle
Is this a good size unit for a 3 br 2000sq ft house?
It could be. I would have a licensed company in your area come out and take measurements. These typically aren't one size fits all systems, it can vary depending on the size of the rooms in your house, and the layout.
@@paultheplumber8665 Where are you located? Do you have anyone you can recommend in Ontario, Canada?
@@grazialionti5677 We are in the southern New Hampshire area. Unfortunately I do not have any contacts up in Ontario.
That evse tho :)
Thanks for watching!
In the girl's room, I would've thought a small unit (like in other rooms), would've worked placed right above the window. That would've been the perfect place. But, I guess the line run would've been a long one..hmm Otherwise, nice video, thanks!
Thanks for watching! If I remember correctly we didn't have enough room for a wall mounted head in the girls room and that's why we went with the floor. Sometimes ceilings like that can make a mini split design difficult.
Please start a HVAC Video series. You will have many followers.
Thanks! Hoping to start putting out more of these videos soon. COVID has definitely slowed the content down.
Wish these could be made smaller.
General cost on this system as shown including install? thx
Depends on your house size, needs and all that
@Weenie Hut Jr's for how many square feet home?
I installed 3 mini split systems myself - 24k, 2x 12k units after rebates and tax credit I paid less than $1500 for 3 units.
Costs to install them is extremely high!
"Runs strictly off solar".
So nothing works after the sun descends??
Typically there is a battery bank with solar panels for the night
What’s happening on the unit at 0:14?
Not sure what you mean. It's running during that time.
We just got a 3 head system installed, may add a head for basement for 1,500.
11,200 minus 5,500 for getting rid of our wood stove. So our cost was 5,700.
Only have had if for a few weeks but like it.
We will probably get a newer epa wood stove for warming our feet, miss the hot heat and for power outages.
We had zonal electric that were too expensive to use so we have heated our home pretty exclusively with wood stove for the last 7 years!

17 miles from woke is for losers, Portland, Oregon..lol
when you say 5 degrees is that F or C.
Fahrenheit
Does each head require a drainage line? Also with new construction doesn’t a cassette unit seem less obtrusive? Why not talk about cost?
Cassette is definitely a great option for new construction, this wasn't new construction.
30 SER is high, 18 SEER is low for a mini split.
Good video but you left out the most important bit of information...how much $?
Lol 30.000
20k to 30k on average for this model. It's a "hyper heat" model that is going to increase the cost by a minimum of 5k.
Normally if you have an honest crew. You could do something like this for 14k to 18k. But that's assuming you get a normal minisplit system and the install crew is willing to do it for cheap.
It may be running off of solar eventually but you can’t say their energy cost will be extremely low because the solar panels will probably take 20 years to pay off.
They're running off solar now, and in June they got a $300 credit (this customer is in Mass). Everyone's financial situation is different so I can't speak to how long it takes for someone to pay off their solar panels.
