I’ve used those rough in box’s on several installs. The only issue I ever ran into was during install. I had a hard time getting the evaporator head to mount flush to the wall. I started to offset the rough in box instead of centering it. That helped with getting everything to fit in the box and allow the evaporator to mount tightly to the mounting bracket.
I just put in one of those little pumps for the Mitsubishi. They could have benefited from a ducted cassette installed in the attic with ductwork to all the rooms. 1 lineset 1 drain line and much better comfort overall considering you can hit the bathrooms and more even distribution.
That's what I would have done, but ductwork is not cheap; this is likely much cheaper and will overall provide enough comfort for what the client likely prioritizes.
Man, all props to your work, and that rough in box is cool! It really feels like the homeowner did the design of this themselves... a whole attic, new construction, and still opting for conventional high-wall ductless heads??? Plus those pumps are crazy loud... Really seems like they could've used a little advice in the planning stage on how to just get a ducted system in there, or at least choose a better type of ductless head for the application.
very true, lots of space for some ductwork. I try to avoid those pumps whenever I can too, working on them is never fun, good old gravity drain done right never has issues
Martin , you hit the nail on the head👍. Plus there’s a basement to take full advantage of (basement duct work and air returns in every room, excluding bathrooms and kitchen). Basements make it so easy.
I agree with you. I’m from Alberta,Canada. We have fresh air requirements we need to meet by code. That is why we use ducted systems-plus we need heat 70% of the year. HRV is tied into the ductwork of the furnace. Or you could do a stand alone HRV system in this case. You need fresh air or this is going feel like a 1970’s apartment. Yuck! My first thought when he said condensate pumps was what about the sound.
For future reference look into the blue diamond pumps we use them. You can fit the pump and the reservoir in the back on the unit. Looks clean and there the quietest on the market
I've used both mini splits and central. For me personally I prefer a central hvac over mini splits. Main reason is just overall comfort in every single room in your house including all bathrooms, walk in closets and utility rooms. To get that level of comfort with mini splits it would require a head per every room in the house which would be extremely expensive and wouldn't make sense when you can just go with one large HVAC system for the whole house. The other con going with mini splits especially on an already existing home is all the line sets running all around the outside of house especially if you're going with multiple heads which is a major eyesore. For larger homes you definitely want to go central. I live near Nashville and every builder of a new construction house is still going with central because of the same reasons. Really not that much of a price difference on electric bill as most people think because you're still not heating or cooling all those smaller rooms in the house. A central hvac distributes all air evenly throughout every room in the house.
It’s all preference, ductwork leaks and breaks down over time and is always a pain to replace in a finished home. Not to mention if you want good airflow distribution, you need a proper air balance done. That is rare in residential homes. Both mini splits and central systems have pros and cons. The only real difference is if you are more comfortable working on one vs the other.
@@cesarmoore7996 , I might agree with you if this house did not have a basement . Central split system is the only way to go when you have a basement;Plus air balancing is not a problem when you put air return in every room (except for the bathrooms and kitchen ) and it’s easy to do when you have a basement with equipment inside the condition envelope.
@@boby115 yes I couldn’t speak on basements because in my area we don’t have any. It would be nice to use the basement as a mechanical room instead of having equipment in the attic 😅
@@cesarmoore7996 , we’re a little spoiled here in the St. Louis metropolitan area, 98% of the homes have basements, going into an attic is rare. Even on two stories we put the second floor furnace in the basement and send the ductwork up between the walls & chases, the architect and builder supplies us with.
I can install Mini Splits all day. Walk in the park. What I really need to know and want to see is videos on service of the mini splits. They are much more complex than traditional air conditioning period show us when you get inside one of those things
Its pretty basic. If it's leaking, you just recover the refrigerant that's left and then weigh the new charge in after fixing the leak. Mini splits are usually either gonna leak or have a part failure like a board. Not too crazy to deal with. Any mini split with a vfd is gonna make it so that you can pretty much just weigh the charge in after fixing the leak. Even with large vrf systems, the way you go about it is basically yeah same thing just weigh in a new charge. The software can do a bunch, but the only real fix im aware of ia to remove and confirm the new charge weight matches what you need.
@@Clasped003 that's pretty much what I've been doing. Keeping them clean making sure filters stay changed, repair and all the f*** ups in the control wiring from the electricians and weighing refrigerant re-adding it when in doubt
Now the best part of this video is the fact that you show to the rest of the world and the people I don't live in tornado Alley area or hurricane zones why houses collapse all the time in America they are nothing but twigs that can be blown down easily I still don't understand after 27 years of being in this country why they build these houses like this to where they can be blown over so easily
I just installed a MRCOOL 4 zone mini-split system. I came up through the floor into closet areas and used the 7.5' cover kits to hide the pipes, the head units were installed on the opposite side in the interior rooms. They did not recommend that you put these units inside the walls in case you needed to service them in the future, so I am good. .....But I am having a different problem..... It's been about 3 weeks now, temps in the 90's, the system is working great so far. But I have a problem. I am experiencing severe headaches in the mornings, and brutal insomnia (no sleep) being around these AC heads. I can tell you it IS the heads causing me grief. I bought an EMF meter to detect the radiation being emitted from these things as I cannot be near these at night trying to sleep. It's been miserable. The EMF meter I bought is a cheaper model and doesn't work well, unless you believe that ketchup and a can of Pepsi are spiking with EMF? I've got to buy a better EMF meter, also have the power company come out and scan these things. I don't know if it's the wire, or the fans that are causing me my problem? It's a 230 volt system, not 110 current. I'm a little bit pissed that I stepped into this issue. I am sensitive to EMF waves and I could of just reinstalled central AC as I had the ducting....Well, I did have it set up until I ripped some of it out. The internet says it is possibly dryness of the air, but I call BS on that, everybody is a liar these days especially corporations and governments. Today I was outside next to the condenser when it was running for about 2 hours and the headache was returning again. I bought some aluminum window screen and wrapped the wire as it enters into the living space, as the waves cannot pass through the small size of the mesh of the metal screen. It seemed to help some, but not a perfect cure yet. I had a portable AC unit, and then a window AC unit earlier in this year while I installed this MRCOOL system and they both caused me the same headache problem. I am sensitive to EMF, and have diabetes which according to some books is caused by electricity, and I believe that from my first hand experience. To find out that this system is also emitting high EMF apparently? I'm kept cool, but can you live without sleep? Your power wire is way bigger than the ones supplied by MRCOOL so maybe that matters? I can run the bedroom unit till ice cold in the master then shut it off before bed is my current work around. I have yet to get my first power bill to see what it draws, but I think it will be less than the central AC system I once had. I also will mention something else that I ran into. I bought this DIY system from Home Depot and HD did me wrong. I had extra line sets, and communication wire, and a coupler kit after installation that I didn't need, but I could NOT return them for a partial refund inside of the 30 days policy. So they broke there own terms of sale. I didn't make the terms, they did. Home Depot will not take back a partial system, and shipping wasn't free either, it was $110 dollars (orders over $45 are free shipping) NOT. This system keeps me very cool, cost me $4700. and is very quiet when running, but the EMF issue is causing me troubles.
Well yes anything with magnets, motors, solenoids, etc will make an emf. Which this unit uses all of them. Can’t say much about Mr cool system as it’s diy and I only install Mitsubishi.
Using those boxes and press fitting!! I hope it's the ticket!! I'm not done yet!! Getting someone to dig my trench on Saturday so that I can do the outside work. Boss didn't want horizontal runs on the exterior. Already 4 line covers going up and inside.
Ruffin boxes are great thing I’ve use them here in South Carolina and the only issue that I have seen is the lack of insulation on the box causes sweating if you dump straight into it
Great work as always Zack. Can you show us when you go back to install the mini splits so we can see how you tie in with those boxes? Mitsubishi equipment it extremely hard to get we’ve had so many issues in the last couple of months. Thanks for sharing your rough in on this job. I’m looking forward to seeing how you set up your van. I also have an NV and it’s one of the best vans I’ve had but it’s so hard to figure out how to set up the shelf’s and the pack out s and still have room to bring out equipment out to the job.
I’ve used rough in boxes in the past. I like them however be sure to hung them high enough on your wall mount is going to be lower than you want it to be
Nice work my friend. I just ran into your Chanel today. Really doing a great job. I haven’t posted in years but take a look and you will see I appreciate good installs! Everyone needs to do nice work. We are paid to do nice work! Spend the money on hood tools and it will pay you back!
I Braze all joints so that would not work for me, i have no time to play with flares behind Mini-split units, but get that money fam i respect it...In any case, great job as usual Zack
There’s always what ifs and how comes, he wanted to do it this way and he did. No need for pointless questions and statements as “avoid pumps like the plague”.
@@cesarmoore7996 I wouldn’t say it’s pointless, I do genuinely avoid pumps like the plague, why would I want something extra to go wrong and more work to clean, not to mention if it’s an pump the mounts under the unit it just looks worse and can get noisy.
Hey Zack quick question where do you get your equipment the Mitsubishi equipment what distributor are you using thank you for sharing you are a top-notch installer I can appreciate your professionalism God bless
Nice work! That Mitsubishi unit should have no problem keeping them comfortable all year round with that insulation job they did. It was smart to do ductless, I think a conventional system wouldn’t be able to dehumidify well enough with all the exterior walls and roof being spray foamed. Thanks for the video.
a proper ducted system even a Mitsubishi Airhandler would be much better because you could have supplys in the bathrooms and everywhere you want it instead of this
@@loganraimer Have you ever tried to condition a home fully insulated with spray foam in the South? The spray foam foam insulation holds in moisture making it difficult for a ducted system to remove enough humidity unless you install an additional whole house dehumidifier which is added installation and operation cost.
Let me know how that goes for you. Used something similar before and had the dry wallers cover it. Also what pump are you going to use those boxes say you can fit an inline pump in them never found that to be the case. Idk maybe they have gotten better
J&B air, my thoughts exactly. Basements are rare in Tennessee and when you get one why not take advantage (?). I’m assuming he’s going to put another mini split in the basement.I am in the Saint Louis Metropolitan area where 98%of the new homes have basements and I have never seen mini splits installed in new builds with basements. It will work but I’d hate to be the guy Who replaces the equipment in the next 15 to 20 years. Maybe he’ll give us some insight why this option was decided upon.
@@keenanwalker6597 , it’s definitely cheaper. If he’s willing to pay extra for a basement,i’m sure a couple grand more on a central split system wouldn’t kill him. Plus with the basement he’s got a lot of options (zone dampers, Central D humidifier, fresh air make up system, humidifier) all possible when you have a basement and easy access.
2 years later.. HAVE you had any issues with the rough in box ?? read some people say they stink because if the drain on them clog ? would like to know our input
I doubt it. My daughter lived in Tennessee and her builder just about got away with murder, things that would never fly in my neck of the woods was common building practices down there (The Nashville Area is just growing way too fast).
Is there a video when you installed the head units? I’m doing some Mitsubishis right now and the drain is making it not to flush with the wall. I miss Daikin and Samsung.
Great video. When doing an interior wall install for the indoor unit, is it preferable to surface mount the line sets and wires in case one of the refrigerant lines develops a leak over time? thanks
Yikes I would've went with 3/8" copper it's sturdier and if they ever get rodents they'll chew right through that water line like they can smell the cold water from the drain lol. Many resturants have that problem and it becomes a nightmare lol
Hey man love the vids been watching for a year now. I just got a new pair of work boots but they aren’t composite toe or steel toe. I was wondering if I need that toe for being a residential helper?
I would have just ran the drain down the wall to eliminate having a whole other component to break down like a pump. Also you could have avoided having potential leak points by just running the pipe all the way home the first time instead of being lazy and just stubbing it into the attic.
Doesn't that indoor hub require the commercial system access 3 phrase power? Or you can do that branch system with normal outside equipment? That would be awesome
Can someone direct me how to run about 30ft of 3/8 & 3/4 inch soft copper for hvac. I'm gonna need to go through two ceiling bends ( 90s ) before bending them out of the walls. They are not charged, empty 50 footers. Thank you.
Why would you put ductless mini splits in new construction . Even if the homeowner ask for that i would've past or encourage them to put full system in . even with the foam it still will have dead spots .
I think the standard grille and vents are quite ugly and they're flushed .... but a giant head on the wall that sticks out like a sore thumb is quite ridiculous. I think ductless are for retrofits rather than new construction.

How come you didn’t just run the drains down through the stud bay, through the subfloor, into the basement and out the side of the house?
I also want to know this
Avoid using pumps like the plague!
he was bent on just 1 drain exiting. I assume he coukd have tied them together in the basement ceiling then exit with 1- 1 1/4
There’s a adapter you buy and I’ve installed hundreds of these in the last 5 to 6 years and never had a leak on any of them

cool boxes. must be hard running your own company and getting sick. feel better

Hey man love the vids been watching for a year now. I just got a new pair of work boots but they aren’t composite toe or steel toe. I was wondering if I need that toe for being a residential helper?
It looks like you put those boxes in right where they have rough in boxes to hang tvs.
Interesting. Like what are pricing for doing this job installing in a Bi level house 2000sqft
I've had issues with drains with those rough in boxes.
You don't have to use fire stop material in Tennessee? The electrician used it.
Basically the same thing I'm building for my bosses house!! But his is vrf
I would have just ran the drain down the wall to eliminate having a whole other component to break down like a pump. Also you could have avoided having potential leak points by just running the pipe all the way home the first time instead of being lazy and just stubbing it into the attic.
How does the drain line drain when it feeds from the top?
Is that black armaflex on the line set? Did they switch over due to the white stuff causing leaks because of chemicals touching copper?
Why did you choose wall units and not cassettes?
Did you get the access panels for the rough-in boxes? Makes maintenance a breeze.
Will you make the flares in those boxs or just braze your indoor unit in ?
Great video! I’m fresh out of high school and I’m going into an HVAC trade school. Any tips for getting started?
Hope you feel better. Curious to why ductless, summer vacation home or boiler for main source of heat?
Doesn't that indoor hub require the commercial system access 3 phrase power? Or you can do that branch system with normal outside equipment? That would be awesome
? 3 phase mini splits? I've done a bunch of these and I've only ever seen 208/230 in a house
@@yoitsrob Mitsubishi City multi
How come it wouldn’t just be a full furnace and AC with duct in the basement and just floor registers and returns on the main floor? Just curious!
Great job Zack, have you ever had any issues with the pumps?
I have all the time..needs to be changd to 3/8 hose not 1/4 constantly getting clogged
Why did you go with mini splits instead of a regular system?
How much was the total square footage?
How do you get a week off being sick? I couldn’t even get a day off when I had covid
I liked the rough in box up until I put a 24 k unit
Can someone direct me how to run about 30ft of 3/8 & 3/4 inch soft copper for hvac. I'm gonna need to go through two ceiling bends ( 90s ) before bending them out of the walls. They are not charged, empty 50 footers. Thank you.
Would have been better and cheaper to run air handler mini splits are a last ditch effort.
Why would you put ductless mini splits in new construction . Even if the homeowner ask for that i would've past or encourage them to put full system in . even with the foam it still will have dead spots .
Put central enough space in the attic..
Putting a ducky in an unfinished home. Easy money.
1/4 3/8 9 k high wall unit then
😊👍
👍
I think the standard grille and vents are quite ugly and they're flushed .... but a giant head on the wall that sticks out like a sore thumb is quite ridiculous. I think ductless are for retrofits rather than new construction.
Hey Zack is this house going to get a dehum added as well? Those mitsu’s don’t pull much moisture out.
Then you sized it wrong or your you are using it wrong. Not to mention depending on the model they have a dehumidification setting.
Have to use the ST model, has a better SHR
Why not just cut a piece of rock and mount the head? 1 sheet can do a couple of heads
Did you catch Covid again?
that plastic box looks like a problem.
That’s work for you ? 😂 😂
Jesus
That van looks empty
Must not get a lot of work
Do you have an e mail
So I can send you a picture of my issues
The way you hold the razor is sketchy AF lol
Bendiciones hermosa Celina que Dios te cuideb donde quiera que verwohntt.online encantan tus videos.
I love doing rough in’s
