Hi,
I have an older Carrier 96 system from 2007 with a fancy thermostat that talks to the other components in the system and has some helpful settings. Anyway, we moved into the house a few months ago so not 100% sure of what is normal for the system. It's a two zone system. One zone is on the 2nd floor and heats/cools our main living area. It works perfectly. Air comes out nicely from vents and even when it's really cold the heat pump can keep up. Although there is a backup propane furnace.
The 2nd zone which has a sensor in our bedroom heats/cools the upstairs bedroom (same floor as main living area), the laundry room still the same floor and an apartment on the 1st floor. If we turn the heat to 73 our bedroom and laundry room quickly get up to temp. Air comes out strong from the vents. The problem is that the apartment stays at 67 while our bedroom, etc. stay at 73. That is a 6 degree diff. I checked the vents in the apartment and while there is air flowing it's not nearly as strong as our bedroom/laundry room. The air trickles our compared to blowing out. I then tried closing all the vents in the bedroom and laundry room and the apartment didn't feel that much of a difference in air flow. Even with the vents closed the temp is held in our bedroom. I tried leaving the vents closed for several days but the air was still not strong coming out of the apartment bents. I even put the air circ. on high but that didn't help.
I think I'm going to call someone but wanted some advice in the mean time. I know that some systems have manual dampers that allow for the restriction of air flow. I was looking at my system to try and adjust the damper but there are wires that go to it. It looks like it's electronically controlled so I didn't want to mess with it. There are two main ducts coming off each side of the main unit with damper controls on each side. There is also a board that has wires that go to the damper. Any advise would be helpful.
