Does anyone have the problem of the upstairs getting too hot and downstairs is still too cold? We put our thermostat on 68 and upstairs is toasty, but downstairs is still too cold. The builder said that wouldn't happen b/c I brought it to his attention. Sure enough, it happens.
I heard if you have 2 HVAC units, that will help with that. I only have one, so any suggestions with fixing this situation?
BTW, my house is only 1600 sq ft.
