Hoping that someone following this thread could help with my questions since my own thread isn't getting any hits.
Haven't been able to reach customer support so I thought I'd check with all the folks who've installed Mr cool mini split ductless heat pumps.
I've got a small house so I'm limited on locations where I could install the indoor units. I was planning on installing 2, at either end, in my finished attic, but the ceilings are low and sloped. There's no way I can get the 70" required height. If I install it under a window, 24" above the wall to wall carpeting, what would happen? Would it work at half capacity? The space on one side of the attice is about 200 sq ft, so not very large.
I just installed a mini-split (I made a recent thread about it on this subforum). It wasn't Mr. Cool, but I'm pretty convinced that they make them all in the same giant factory in China and then assemble them in another giant factory in Vietnam or wherever and then someone buys a million units and slaps their brand on them.
The indoor unit is supposed to be higher than the outdoor unit, but I can't think of a theoretical reason why that has to be other than for the water condensate to be able drain down. The coolant moves in a circuit, both up and down. Maybe it makes a difference whether the bigger line has a gravity assist compared to the smaller line? I don't know, but I would very surprised if you were to lose any noticeable efficiency from having only a 24" difference in elevation compared to 70". And if the unit is oversized for your needs, then a small loss of efficiency won't matter. The idea that you might lose
half your efficiency sounds ridiculously unlikely to me, but I think that "index" knows more about this stuff, so maybe they will chime in.
My 2nd question is whether Mr C manufactures an indoor unit that has tubing that vents to the left side, as you look straight at it, rather than to the right. The only location in dining room, that doesn't require drilling thru a back porch, needs a left sided hole for tubing and power.
Again, I used a different brand, but on every single one I looked at, you can go left, right, straight back, or whatever works. You just have to bend the lines. You have to be careful when doing this because you don't want to make a kink, but they are meant to be bent. There are even knockouts on the plastic on either side that allow the lines to go through in either direction.
