Ok, I want a cooler garage this year. I have been planning to install
a mini-split for several years now and this is the year.   Power will
be a slight problem, shop has plenty but none where I want the
compressor to go, so have to run some power. Shop has 200amp sub-panel
40ft away from where I want to install compressor. Not a big deal BUT I
saw a 18k btu window unit at Home Depot and was thinking that should
work great and be half the price.
 My shop is 24ft x 40ft so 960 sq. ft. 9ft tall walls of 2x6 filled
with insulation and I went overboard on ceiling insulation also, stays
cool until mid-afternnon on hot days then becomes a oven for the
evening, I live in S. Calif. I already have a Hot Dawg gas heater so I
don't need the heat that a mini-split would provide, but might be nice
to get rid of the Hot Dawg (doubt that I would) and have one unit do
both.  In the "shop" area of the garage I have barn doors that I welded
up forever ago, 1x2 steel with a plywood exterior, i have not
used/opened those doors in over a decade, they were installed when I
built the shop just so I could get my lathe and mill in easily.  I have
no windows in the shop so I was thinking I could put this window ac unit
in one of those barn doors, the frame will easily handle the weight and
it would be a super easy hole to cut and install the unit into, I think
even the hinges would handle the weight but I can get stronger bigger
hinges if I need them. Then I have dedicated 50amp plug right next to
that for my TIG to plug the unit into, I weld mostly in the front of the
shop anyway but I wired every wall with a 50amp for the TIG and 30amp
for the table saw when I built the shop (I really went overboard on wiring).
 So what would you do ? mini-split seems to the answer but half the
price for a easier install window unit and cut a hole in a unused door
seems like a good idea, good ideas are often the worst...
