I have 1-1/2 story cape code style house with a 4-ton unit with 3 zones: 1st floor, 2nd floor bedroom 1, 2nd floor bedroom 2. There are return-air ducts installed in the ceiling of both upstairs bedrooms. Each upstairs bedroom (zone) has it's own thermostat. The return air ducts work very well in the summer to pull the warm air out of the rooms.
But in the winter time, I'm wondering if the return air ducts are actually pulling the heat out of the room and making the system work harder. The system seems to run too long to maintain the bedroom temp setting of about 70 (68 ok with me, too cold for wifey). Would partially blocking off the returns help ?
