    "Ikeler" home. Flat, foam roof with cassettes. MXZ

    I would love to say I found this. I fought tooth and nail not to do this. But this is a MXZ5c42 with a 12k and 9k wall mount. A 12k one way cassette. A 9k and 12k 4 way cassette. Line length was 210ft furthest being 70ft.
    We had to remove 2 swamp coolers and enlarge the holes. This style of home has romex running across the top of the 2x6 t&g boards. So cutting is fun. The boxes for the 4 ways are 36x48 and the 1way is 28x72. Headed back tomorrow to finish the final details(a few straps, paint pvc, walk through ect ect).
    I cant begin on how much I didn't want to do this. The 12k wall mount points down the hall at the 12k 4way while doing nothing to condition the frontroom/living room that its supposed to serve. The 9k is in a sun room thats probably 80% glass on the walls with 3 skylights and the room measures roughly 200-350²ft. The 12k 4 way is tucked into a quasi corner of the dining room with only 2½ of the vanes actually able to do something. The 9k 4way is in the hall way just past the laundry area and centered between two bedrooms just outside the bathroom. The master is a 12k 1way that positionally I can't complain for what it is.
    This is a 2500²ft home with zero insulation on the walls and 40%ish glass for walls. 4 bedroom 2 bath. It's just blah.

    Why not just mount the condenser on the roof? Would have saved a lot of piping it seems.

    Thats where the owner and boss decided it should go. I was so dead set against these giant holes on the roof that I didn't think about condenser location. A few inside pics.

    Bro. Thats all we can get anymore. Boss doesn't believe me on that so he and he alone will pay for it when the time comes.

    I did my best... unit measures 22½ X 22½ and sits inside 36 X 48 box with service side getting the extra space... not much but its something... last one boss did nothing inside for structure and the foam started to collapse the box. Plus he only made it 6" bigger on the service sides and 1" clear elsewhere. I flat said don't ask me to go back.

    Green obviously is the outline of the house. White is to show the glass walls. Blue is the wall mounts. Red the 4 way cassettes. Yellow is the 1 way cassette.

    The only thing they sell is white insulation.

    I still have yet to have one hole in a single white lineset, this is going back 12 years at least. Must be a regional thing.

    I think it has more to do with brand. Some cheap brands had problems.

    I've used PDM and JMF with no issues.

    I am not sure this is really a shameful thing. I kind of like it when folks think outside of the box..literally on this one. You can't be conventional on everything especially when the home is not conventional by ANY means. If a customer is willing to pay and is fully aware in writing of the scope, complexity, and deisred intent of the job, then I will do anything a customer damn well wants.

    I will say great job.

    Yet I have seen them fail as early as 3 years after installation and the evaps on wall mini splits also develop pinholes at the steel sides to the copper tubing inside...

    Some debate it’s the remanufactured copper mix that’s sub standard in recycling...

    Seems clever. I actually like that top access from the roof idea.

    I just don’t understand the mix match between piping in the troughs vs random across the roof zig zags.

    Probably would have been cleaner with the condenser on the roof, as was mentioned.

    Could not have been more vibration then the swamp coolers.

    I am still in contact with most of these customers. No issues.

    I will take my chances. If there are issues 5 years from now then they will pay me or someone else to fix. Is what it is, they are very popular, and the black stuff sucks, the Mueller stuff included.

    Mueller has a black coated armaflex out now that is very similar in toughness on the exterior to the white insulation.

    I happen to have a sample:

    On second viewing perhaps the zig zag white tubing was existing, water lines?
