Suggestion for future installs - consider marking off your ceiling cut lines with the edge of blue painters tape. And by using a couple of additional widths of tape around the perimeter of the initial cut, you protect the paint from smudges 👍

All I would add is cleaning these. I know many people think these head units don't require much cleaning but they do. It's unpleasant enough to clean wall mounted units but these on the ceiling also look hard. I have a pretty good method for cleaning my wall units but unless these ceiling units are more serviceable then I'd stick with the wall units. What all these units should have is a simple way to remove the necessary parts for cleaning without getting into all the interlocking plastic parts (and tabs) which makes getting it all back together and quiet a tedious task. If the blower wheel on these ceiling units simply drops down and out (without removing too much plastic housing) then I might be sold. But something tells me that is asking too much.

@25:45 They have a filter at the intake before the fan to keep dust out of the unit. The filter lowers down to help you clean (not change) it. They copied this from the Japanese manufacturers. Do people tear down their attic based central HVAC equipment to scrub the fan blades? No they do not.

I do like the idea, practicality takes over and service on each unit can be tedious. Condensation drain on each unit needs to be checked and cleaned. Great idea, still requires more maintenance than a central unit , but if a central unit isn't possible, this is a good workaround.

In climates with any humidity, ceiling cassettes installed with their open backsides extending into unconditioned space are going to sweat with condensation. The entire case needs to be well insulated and sealed with a vapor barrier to prevent this. Otherwise there will be mold and possibly ceiling damage from water.

I remember installing my first one... I was in Iraq and re- built the failing fun room in front of my "Container Housing Unit" or CHU. I built on a new roof and put up rafters, reinforced the exterior walls, added a couple windows, and I ran a 220 volt 60 amp line to my add on via a new main panel. The only thing I needed was temperature control so I got a hold of a mini split. I then needed a vacuum for the lines since it was brand new. I used my medical suction and was able to get the desired vacuum in the end. That served me well and the new tenant, once I returned to the US, inherited the whole deal. It was a fun project on FOB Warhorse in the Diyala Provence of Iraq.

In Florida because of wind loads and stress on the roof, and especially since you have access to the interior of the gable end wall, I would do a reinforced wall mount with extra king studs to jack studs and two headers to attach the wall mount to. With investment in a few 2x4s, some 8d nails, and a rated mini-split wall mount bracket, a wall mount will not only remove load from the roof but also make roof maintenance and replacement much easier in the future.

Two comments: 1) Ceiling cassettes require condensate pumps. Make sure to add algae prevention to your maintenance plan to avoid clogging the pump (PITA to access the pump on our Mitsubishi units) and 2) Individual room temp controls is fantastic, EXCEPT in Spring/Fall. If you have multiple heads on a single condenser, it can only operate in cooling or heating mode (of course....but people forget). In seasons with big temp swings, folks in different rooms may want heat or cold for comfort. Typically, the first unit turned on in the system will be the master (setting cooling or heating), and the others will be master to that setting.

I personally don't like the idea of having the pump and any service issues like that. It being up high and flush just makes me think getting in there is going to be even harder than with a wall mounted unit. On my wall units I do one cleaning each season to help keep any clogging of the gravity drain line and other grime from building up. Getting to the blower wheel is hard but I have found just using a self-cleaning and washing formula is better than trying to take it all apart each time. I simply turn the wheel and spray it lightly which helps the formula dissolve much of the dirt. BBJ Micro Coil Cleaner etc.

Homeowner installations don't require an inspection (complying with codes) so many problems I see in this install won't get flagged. The insulation, dust, bugs, mold etc in the attic will be pulled into the air handler. And the plastic filters will have to be removed and rinsed out rather often. Easy enough in the units mounted horizontally on the wall but I don't know about these. The units will vibrate if very softly and this will cause some problems with the structure of the house. The wood will transmit these sounds.

My GF was always less cold in her office so she can turn up the temp. All I had to run was power control cable and two freon lines each unit. Install took me a weekend. Im no expert. Lots of youtube videos. Bought a vacuum pump and torque wrench which I loaned out to neighbors doing mini splits. Abandoned the old ceiling ducts and blower. Huge electricity savings. Old unit 30kw. New unit all going 15kw.. Heat and cool. Great for 3 years now. Maintenance just clean filters monthly.

Downside of the Mr Cool pre-charged is that it cost much more than an equivalent mini-split where you evacuate the tubing with a vacuum pump. You can buy a pump for ~$70 (much less than Mr Cool premium) and use it in future AC work, including on your cars. Also, you can't cut and flare the Mr Cool tubing to fit so need to coil the extra.

In this house the attic insulation is meant to keep the heat out of the house, not the attic. And the ac unit will use the hot attic air regardless of the insulation and have to cool it, unlike the units installed in a closet in the house which use the recirculated cool air in the home. The attic temperature can soar to 120 or hotter, ask any duct installer. So instead of cooling 80 degree air to 70 you'll have to constantly cool 120 degrees to 70. That's lowering the temperature by 50 degrees rather than 10 or less.

We installed a mini split system with one outside compressor running 4 interior room HVAC wall units. I'm NOT saying these aren't perfect for some situations, but please beware of a couple of considerations. 1. Our mini split cools and heats the air perfectly, except there is no air exchange. Unlike with a conventional system, if you are dealing with something or someone that smells - you can heat or cool the smell, but it's not quickly removed as with a traditional HVAC system. Lastly, our system lasted about 6 months past the warranty. When the installer came back to service he was embarrassed to say that the parts were so tiny in the outside compressor, we would have to replace the unit as repair would have been more expensive than it was worth. Separate conversations with friendsnwho have similar systems exposed the same problem. As of this point in time, we simply aren't running the system at all, and will likely go back and install a traditional duct system.

Very cool install, love these ceiling units as they are not so noticeable as on on the wall. I am not sure but in Ontario we use vapor barriers to prevent air going from cold to hot areas and create condensate. This must not be a problem in your area as I see no kind of vapor barrier used in your install.

Unfortunately, all of the air conditioner manufacturers seem to design most, if not all of their window units and these mini-split systems too, in the same way. With cheap plastic and Styrofoam that readily grows mold and mildew, they're not maintenance or serviceable - friendly, and they all use flimsy, pathetic filters that don't filter the air anywhere near enough to protect the unit from getting excessively dirty and clogged up with mildew, dirt and mold, that's nearly impossible to get clean again, at that point! It's frustrating to spend hard earned money on something and then be forced to have to replace it, in just a few years, because you can't keep it clean enough to continue operating normally, nor efficiently, or just can't clean it well enough, at all, in general. Everything nowadays, seems to be designed as disposable, but with the price of something that should last for decades! So you’re forced to spend more money, sooner than ever before! It's despicable, as far as I'm concerned.

I'm really considering this my main AC 4 ton goodman rooftop unit went out in Aug 2022 I'm in Phoenix wife wanted it fixed by next day. HVAC company took advantage got me for $8900 to replace it with same unit suppose to be 14 seer the old one was R22. This one my electric bill is at least $100 more a month had it checked it's pulling 20 amps a leg. What I think is the R22 seemed to reduce current more when it was cooler like at night, or later in year like now were in the low 100's. I put in a 12k Pioneer inverter mini-split in my garage can't believe how cool it keeps that garage I set it to 79F my home AC is set to 74F go in the garage it feels cooler. I run it on ECO mode it's a 240V model pulling 1.4 amps. I could wall mount it to the side of the roof like yours I have a flat roof and a pitched roof in the middle. My roof is foam so have to mount it on the side of the siding.

I like it but prefer the attic cassettes with short run ducting. We do have one Mitsubishi ceiling cassette in a home gym. The rest of the house, 8 zones are vented out through slot defusers. These type systems however, should become the norm and to just say to conventional ducted systems. No phone apps in my house, just a Mitsubishi thermostat in each zone.

At our previous house I had a Carrier mini split installed for our bedroom and bathroom. Each head unit had an aftermarket condensate pump. I don't know why they did that, but we had to clean the condensation tank about every 3 months due to mold building up inside and inside the drain pipe. Furthermore, the pump motor only lasted a year, so we had to keep replacing the pumps. Our experience was not a good one.

Something to note about "knockout" tabs is that they were never meant to be directly struck with a hammer... you get a screwdriver at the corner opposite the thin 'join' line and tap it until you have enough room to use the screwdriver as a wedge to widen the gap. Then use Channel locks or needle nose pliers to grab the tab and twist and/ or wiggle the tab loose... swinging hammers around electrical equipment is bad juju in most circumstances, even without power connected. Also be extra cautious that you meticulously clean up the chips from that step drill and don't let them get into anything or you will have arcs and sparks and a dead unit to replace. I am also curious to know why those are 3 Phase breakers in a house (which is a rarity in most residential units) that is generally wired single phase unless you specifically have 3 phase wiring available...either that or it is being fed by the condenser unit? I may be mistaken, but I would really like to see how they did the wiring distribution for those. Other than that, a pretty decent job overall and I really like the ladder hoist!

This is pretty much what you see inside Japanese commercial buildings. I believe, I could be wrong. Japanese residential houses have single units or splits that look like single units. No central heating or cooling. I think they are more efficient than US HVAC, but most Japanese homes have very inadequate insulation and they end cycling a lot more than they should.

I am building a house, planning on mini splits. These new type ceiling units would be great if they didn't mark them up so high. Really not that much more to them than the exposed wall units, but they think the things are made of gold. it's just a different mounting for the same basic components... Why is the 18k BTU with ceiling unit almost the price of the traditional mount 36k BTU? That's insane. I'm a fan of using 4 single zone sets instead of 1 4 zone outdoor unit. If one of the single zone systems goes down for any reason, you still have 3 completely functional zones. A couple of box fans and you can keep the whole house livable, instead of the one unit taking down the entire system, leaving you panic buying window units to deal with those 110 F days here in Texas.
