It's summertime here, and although my air conditioner is "working", by this I mean that cold air is coming out of it as I can tell when I go downstairs. Having said this, it is still too hot in the second floor. When I set my thermostat to 75 degrees, the unit still chugs and chugs and the second floor never gets cold enough to shut the unit off.
I think I "might" know what the problem is, but I'm not sure. I've decided to replace the popcorn ceiling on the 1st floor, and this means that there are some areas in the ceiling on the 1st floor which are open, until I can put the gyprock up and ceil them off. This is the only thing that has "changed" since last summer when the HVAC was working fine.
Could this be the problem? I'm not totally sure exactly why as there are ducts is taking the cool air from the HVAC to the first and second floors. I can still feel the cool air coming out of the vents in the second floor.
Having said this, is it possible that the cool air is leaking out of the ceiling in the 1st floor now that it is open, and this is preventing enough cool air from going to the second floor?
Is there a temporary solution til I can get the gyprock up?
Thanks Sam
