A/C and Heat 4 car garage

[zx6rrider]

Trying to figure out the best way to go for cooling the garage. Its roughly a 33x50 (1500 sq/ft) attached garage with 10' ceilings. Finished in drywall and insulated. It has 4 ceiling fans already and 2 smaller windows. Its decent most of the time with the windows opened and fans on but on humid days still not real comfortable to work in. Biggest window unit that will fit is a 10k BTU, I tried one hoping it would kill the humidity and cool the main area I work in but it didnt touch it.

For heat, I have a 5 panel gas wall unit that does ok but the downside to that is that it is on a private gas well and if the house and that are both running, it will use all the gas and kick off until it recovers. This winter Im hoping to burn wood to heat the house and use the garage heater when I need to work in it.

With that said, I'm looking to use electric since we dont really have a 100% reliable source of gas. Just started looking at the mini split systems that people mentioned on here, how are those for heat? Would that be able to keep the garage at 50 when it 20 deg outside (southern Ohio)? Are there any other options I should be looking into? Are the size rating pretty accurate or what size should I be looking at?

This forum has been a wealth of info so far, thanks alot

Mini-split heat pump. Hands down the best tool in my garage. I have a 1 ton Mitsubishi that I installed myself. You can buy them online from several vendors.

Have you used it much for heat? How well does it do?

The Mitsubishi Mr slim is what I use to heat and cool my garage. I was suprised at the great job of cooling and heating it does. Ive had it for a year now and love it! My garage has 10 ft ceilings but it is only 24x 30. I think anything much larger, the one unit would struggle so I would put two in if I had a bigger garage. East Tn weather btw

It works very well. I have the Hyper Heat model. It's supposed to be more efficient at lower ambient temps. Even with the cold winter we had this past winter, it was great in my garage.

Good to hear, sounds like that is the way I should be going. Thanks

I also vote for the mini-split heat pump. I have one in my garage and one in my office over the garage. Mine do a great job winter or summer (granted, my winter needs aren't quite as severe as yours but mine did handle a cold snap of below 10 degrees F for a couple of days without issue.)

A proper mini split should work great ... you need to size it correctly to insure you will get enough heat in the winter ... some units will work better at lower temps .. like the hyper heat mentioned.

It's not polite to ask questions about such a large space without posting pics!

Just giving you a hard time. I would like to see your space.
