I have a 3 level house, lower level unfinished basement, Master BR in main level, and in upper level we have 3 bed rooms. I been noticing that my bedrooms upstairs are HOT. I notice that bedroom in middle is more hotter than the other two bedrooms. I have two thermostats, one to contral first level and the other one controls upper level.

could you all assit me in figuring out why it is so hot upstairs do I need to fiddle with Thermostats?

I believe I have a heat pump, how do I check this? I do know that I use gas for heating? I have a furnace swithc in the basement right next to Heating and air conditoning euipment. Equipment is of Lennox model and of type 80msg.

Any help, pointers and tidbits will be highly appreciated
