I have decided its time to adjust the dampers in my ductwork. Currently they are all open and I think some of the small rooms are taking air from the open living room and dining room.
I was thinking of getting some basic thermometers and adjusting until each room matched the thermostat. I was wondering if I would leave a bedroom door (there is a return in the room) open or closed during the test. I have a 1250SFT ranch, is it better to have the dampers adjusted for AC or Heat? I dont want to mess with changing them every season. I was thinking of setting them for AC because the heat seems like it may cope better with the airflow a little off.
If anyone has a better method or knows where to get some cheap accurate thermometers please let me know. Thanks.
