My shop is 12X18. I installed a 5000 btu a/c through the wall, didn’t want to give up my windows. If I had it to do over I’d get a 6000 btu. Mine is OK when it’s low 80’s, but barely keeps up when it hits 90. I was limited by the width as I put it between studs. Shoulda sistered the stud and used the bigger one. I run a small round fan mounted upside down on the ceiling as well as the a/c on really hot days and that helps.

I have a 6000 BTU AC unit in my 14 X 21 shop. You need to have your shop very well insulated and put a furnace filter over the front of your AC unit. I also have a ceiling fan to help move the air around. If your shop is well insulated, it does not take long to cool down the shop and it holds the cool longer. The furnace filter keeps the AC unit from clogging up with fine dust. I change it ever month in the summer and it is held on with straps (see workshop pictures)

Lucky here that my basement shop in this new house is heated and cooled by the home system. Keeps the humidity down in the summer and because its in a basement garage the earth keeps it fairly well insulated anyway.

It is an absolute joy to work in such conditions. Really cold spells in the winter will keep the garage side a little on the chilly side but one of those oil filled portable electric heaters is enough to knock the chill off to work fairly comfortably.

Hi Tom,
Thanks for that tip about the furnace filter over the a/c. I noticed that I had a ton of saw dust on the fins and I’ve used my compressor to clean it off in the past. I tried using a couple of paper towels as a make do filter and they seemed to decrease the a/c’s performance. I cleaned the a/c again and put a furnace filter over it. Wow! So far so good. I had to sand 5 boards and there was a ton of dust on it.

I just open the doors and turn on a fan but then it never actually gets anywhere close to being hot in Seattle.

Window ACs work great, because they not only cool, they dehumidify at the same time, which is good for my wood and tools. If you don’t have a lot of humidity, you could go for an evaporative swamp cooler. They’re a lot cheaper to run and can still knock down your temperature as much as 20 degrees.

Hey, Bird. I’ve got a 12×20 shop located in the woods with windows on both ends. I have a 20” box fan facing out on the far (yeah, 20’) end and it just draws a cool breeze right on through…screens are a necessity though.

I’ve got a 5000 btu window unit. It’s hidden by the trees outside, so it doesn’t terribly disrupt the charm of the exterior. It cools my tiny little shop just fine. Now heat? that’s an entirely different story. Ask me what I’m doing in December because this past winter was horrific out there! Good luck!

Coastal Texas here. Hot as the Devil’s living room and humid to boot here.

I have an 18×20 shop with 9’ ceilings, and only the overhead doors and ceiling insulated. I cool with a 14K BTU portable AC unit and it does a good job considering the lack of insulation. I have tested it vented through a window in a friends 12×18 insulated Tuff Shed, and it will turn that thing into an ice box…

I tend to move air around in my shop via the overhead air filter, which keeps the air conditioned air circulating in the shop…

For what its worth, depending on your situation, given enough insulation, sealing etc… You might be better off just letting the AC run instead of letting it get hot, then trying to cool it off. It takes a lot of energy to overcome “thermal load”, but then again, you aren’t in a big space, so thermal load won’t be all that much…

And before folks get over me for running an air conditioner in a poorly insulated space, full insulation upgrade is in progress. This is NOT a long term issue…

25,000 BTU window unit, although I’m really considering a mini-split-unit because of the noise and vibration. However, the unit only runs in the very hottest months. The R19 wall and R30 ceiling really paid off, most days a small fan is more than enough to keep me cool even here in Florida and I only need a small space heater a handful of days during the winter. Actually, my biggest source of heat is the cyclone, it heats the air 10-15 degrees.

18,000 BTU mini-split unit here. Low noise, and cools great. Actually more efficient than my central A/C unit. Only have to make a small hole in the wall to run the copper tubing to the compressor that lives outside.

Surely, it can get pretty hot in your shop, it can get uncomfortable or intolerable. What you need is some cooling to make you comfortable in your workplace. provides you the necessary services for your cooling needs.

south75storage, I don’t think those guys are from around here.

Reply to birdguy: I just installed a 14,000 btu cool / 12,000 btu heat unit from Haier. Around $500ish. No regrets, doing great and good warranty.
