I'm considering adding an evaporative cooler next summer, the Fujitsu mini-split will help dry the air as they cool it in conjunction with the swamp cooler.
    Just curious, but what makes you on the fence about your Fujitsu unit? Does it simply not put out enough heat or is it way expensive to run?

    I'm getting one of the smaller, single AOU15RLS2 units. For some reason the higher efficiency inverter driven designs seem to only be in their single units. I would've gotten a double headed one like you, but the energy efficiency numbers seems quite a bit better for the single head ones. I wonder why they haven't brought that technology up to the whole house units yet.

    Funny how before my injury I used to ski 100+ days a year and was completely numb to the cold, as in people thought there was something wrong with me because I never seemed to be affected, but now I hate it!

    Can't stand anything much under 65-70°, and hell was going outside when it's below zero. Funny thing sense I live up in Northern Maine where it gets that way many days every winter. Would never consider staying here if it wasn't for the close knit community that all look out for me. Crazy how much the community can mean when you grow up in a small, tightknit place, and that seems to be amplified even more after they all went through my injury with me. Could never imagine leaving now… Arctic cold weather or not!

    It just didn't keep my house cool lat summer, haven't used it for heat much as I like my baseboard hot water. I am optimistic that the 8"+ of blown in insulation I gt last week will help a lot with cooling, it seems to be keeping the heat better already. I never lived in the house without the Fujitsu, so have no way to compare energy usage or comfort level without it.
