I've got a Carrier 38YKC Heat Pump. I believe it's a 2 ton unit. My apartment is rather small (800 sq ft) and while the unit provides decent cooling in 2 rooms, there's a 5-10 degree differential in the 3rd. The apartment is symmetrical with windows of equal size in all rooms that face the same direction, so I'm a bit lost as to why one room (right side) might be so much warmer than the other (left side).

Is there any way to adjust it so that the right side room gets more air flow? Otherwise does anyone have any suggestions on what I might try to get that right side room cool? (I've installed a ceiling fan already but that hasn't helped!)

Thanks..

 

You're probably not getting enough air into the warm room. If this problem has always existed then the ducting needs to be evaluated. If it's a new problem, then maybe the duct going to the third room is leaking air somewhere.

 

C heck and see if the blower is on high speed. Also close down the registers just a little in the cooler rooms.
