Frame a hole in the wall for a thru the wall ac unit. A
Mini split is most efficient when running 24/7 and not short blast. Then decide if insulation is needed.

I did a 12k mini split myself for under a grand.

I had a mini split installed in my garage last August when I had to replace one of my central units. It is a game changer. Cools/heats/dehumidifies. I keep it on 78 to 80 in the summer and the garage stays pleasant to work in.

My choice if one wants to be frugal is frame out for a window unit and get a 12,000 BTU 120v window unit for about $450. It won't be as efficient as a mini-split but it will be a quicker/easier install. If you have 240v handy you could get a 18k BTU for not a lot more money and have quick pulldown times so you don't have to run it so long before it makes it comfortable to work. The 18k and probably 12k would be fine with no insulation and the time/money spent on insulating buys a hefty number of KWhs.

Do NOT buy one of those little portable units. They’re incredibly inefficient and they’re nowhere big enough to cool down a garage, even just a few degrees.

Since you don’t have a window, a mini split is your only real option that you’ll be satisfied with.

We have a mini split for a big garage (around 750sq feet). The walls have batt insulation but the garage doors weren’t insulated. It does a good job keeping up but I knew the garage door were bringing in a ton of afternoon heat. Anyway I put up this relatively cheap insulation and this was the difference:




It helps out ALOT. Can order it right on Amazon.

Damn, that is a big difference. Looking like I’m going to go with a mini split. Will see how it does when installed, and may insulate garage door and roof if I see a need for it. Definitely not insulating the walls though, that’s gonna be way too much work/$$$.

Yea it took a few days of work to cut them to the right length and we have an 18 foot two car garage door and a golf cart garage door so instillation was a little tedious but it made a huge difference. “Reach Barrier” garage kit.

I need to do this to my garage door. It is Southwest facing.

Also, I would have tackled a mini split on my own, but my garage has a crappy setup where the power and lines had to be run up through the attic and over and out to an exterior wall near the other AC condensers. It needed a professional install.

I used a kit from Home Depot to do my garage.

If you go with a portable AC make sure its a dual hose unit. They prevent your room from intaking outside air because of the negative pressure like most other single hose units.

FYI i have been looking at one on amazon for $500. Its a 14000 btu. I want it for my screened-in patio.
