[Shop-talk] It's hot and I want AC

[Battmain battmain]

I did a mini split unit for my master bedroom. The hardest part was getting through the 12" poured concrete at the base of the roof to run the lines outside. A rented hammer chisel took about 2hrs and a lot of cussing. I love the unit though and so does my wallet. The central AC does not have to be set as cold and the mini split runs when I am in the room. The online electrical stats show the unit pulling less power than my toaster oven most of the time.

There are quite a few calculators out in the web to help with sizing, but consider also the dual or triple output units  instead of just a single output. That way if one can't cool the space, you can use the others to help. These things are so efficient I was considering ripping out the central AC I just put in and adding one to each space in the house. Install was relatively easy other than the concrete part and was a much easier than the central AC install.

I've got about 1000 sq ft (35 x 28) with 17' ceilings.  Two insulated overhead doors (12x14 and 10x10).  The shop is reasonably well insulated (mostly) and I'm in southern Indiana (often low-mid 90's and humid).  I'd probably put it midway up the wall and have it blow out into the bays.
