AC in Garage

[George2615]

Funny... this is a geographic thing. I want heat in my shop. A/C is never a consideration. I imagine your humidity is plenty but what about a swamp cooler. Way out of my league here. Just :stirthepot:

The OP didn't ask about heat, just A/C and I spend time in my garage in cooler weather also. I heat mine using a mobile home furnace. Also have radio and TV. Can't justify adding a bathroom or I'd probably live out there.

Yes, heat is fine already. The coldest it got in the garage all winter was 48 deg in the center.

For me the heat and humidity in the summer are a concern. It takes a while to get hot inside the garage because of the insulation, but it gets in the low 90s if I remember.

well, A/C is really doing the Dehumidifying for ya.. Do a heat gain calculation .. It should get you close to what you need for cooling. here's 1 that may help you.. it should give you some idea..
Don't forget.. people (like a lot of things) give off heat

I ran the AC calculator above and it shows 18,000 BTU. From everones comments and my own educated guess I guessed either 15k or 18k. Thanks folks.

Run a dehumidifier anyway. It will make your AC unit more efficent. All that water dripping off the coils is steeling some of the cold. I run a dehumiifiier in my garage all the time, it keeps all my tools from rusting. It can get pretty sticky without it.

I would put a 3 or 3.5 ton package unit on the outside and duct it in.

Just for comparison's sake, I had a 9,000 btu mini split put in my new 14 x 20' shop for $1500 this spring. This is for heat & air both, quiet & supposed to be very efficient. I've been running it at 73* the last week with 95-100* weather outside, turning it on about 7 am & off around 4 pm.
