I live in a 3br townhouse in NJ. It's brand new as of 2008 and I am the first owner of it. It's got central air of course but for some reason the master bedroom is always HOT and STUFFY. I bought a window unit a/c to help cool off the master br and it works well but during this time of year it cools down outside causing the compressor of the window unit to shut off. The central air won't kick on because where the thermostat is downstairs is very cool and comfortable. I've tried opening the windows but if there is no breeze, all you get is a BR full of pollen by morning and it's still hot. Any suggestions?
