Mini Split

[stlhooked]

I have a 26ft x 28ft x 8ft (725sq ft) garage.
I think I'm going to get an 18,000 mini-split.
What R factor should I use on the wall?
What R factor should I use for the cieling?
Is 220 hard to run out to the garage?

Maybe I should go for a smaller one like a 14,000btu 110 and a higher RF insulation. Should I use RF49 on the cieling?
I really like the Sanyo and Mitsubishi models, they sure are expensive though.

I like the Fujitsu 18rl with a seer factor of 19 for $1900 compared to the Mitsubishi for the same price with a 16 seer value.

My garage is 22x22 and was advised to go with 18,000 BTUs. I don't think you should go any smaller.
