Air Conditioning Garage

I live in the south (florida) and heat and humidty come free with every garage.... my garage is 28x20 (560 sq ft) ... I have no windows either...

I have a portable ac unit now but it can't keep up...

I thought about a mini-split or putting a vent from the house ac in there to put in cool air...

I put the boat in there almost every day wet so there is alot of humidty in there..

anyone have any ideas?

Do you have ceiling fans in the garage - It will help to get the air moving as much as possible.

You will have to insulate your garage for it to any good. It also depends on the size of A/C you have.

Do you have a place to put in a PTAC unit??? The style used in motel rooms, all in one unit, 15k btu is around $700, works great for our insulated 30x26 garage. Has the ability to heat, but probably not needed for you.

He went with central air in the house and we installed the leftover units in his garage. We had to wire for 220 for the compressor, and used the compressor connection to power the condenser, which was also 220. That was simpler, but there were some NEC issues we had to ignore. We also had to get a regrigerant guy in to charge the lines. Very cool units.

Unless you want more humidity, hydrocarbons, etc. in your house. Do not install condition air supply, from your house.

The simple size calculator, will approximate cooling needs for an attached room, but not a garage. There is more infiltration (leaks) in a garage install.

What temperature, do you want? And at what humidity level? Most importantly, how much do you want to spend?

If you give me your, actual location (nearest big city) I can give your the Manual J load info.
