Hi. I have heavy swampy heat during the summer. The guy who built my theater room setup recommended I get a Portable Air Conditioner. I was wondering what options you guys think are good and what I should look into. I'm open to whatever. Hands on experience prefered, thanks. ~300 Sq foot theater room. One "doubled window like this [ ][ ] Room is above Garage! Single story house. Stairs go to a finished bonus above garage. Strong HVAC but upstairs is a good 10-20 degrees warmer no matter what I try, especially if i close everything up and watch movies etc.. I would prefer to keep my HVAC normal/low and then have the theater room "catch up" than to crank up the HVAC in the house and have it be freezing in the 1700 sq ft house and fine in the 300 sqft theater room. Hot Swampy North Carolina Summers.... Thanks!!!
