I have a standard size two car garage that I'd like to buy a Portable Room Air Conditioner for since I sometimes spend some time out there and in the summer it gets pretty hot in the garage. I can cut a hole in the ceiling for the exhaust vent and rout it so the hot air flows out of the vent on the gable end of the house so that won't be hard to accomplish. I just wanted to see if anyone has any recommendations on what is the best model / brand to be looking at. Also, is it necessary to run a dedicated electrical circuit from the fuse box thru the attic out to where this unit will need to plug in at? There is a standard 110v plug not far from where I'd like the unit to sit, so do they have Portable Room Air Conditioners that run on 110v or do they need 220v? Any ideas/advice/experiences that would help me figure this out would be appreciated. Thanks!
