I live in PA and my home was built 7 years ago and a Carrier Model 38TKB036300 central air system was installed. The home is two stories, has about 3200 sf living space, with a 500 sf great room that has a 20' ceiling. When I turn on my AC, it will only drop the temperature 1° per hour. (It has always been slow to cool. We've had the original heating contractor come out for service and he tells us everything is fine). Registers are in the floor and a run a ceiling fan to draw the cold air up into the room. Returns are high on the walls and are no vents or returns are blocked. I don't feel that the unit is sized right since it takes 5 hours of continuous running to lower the temperature 5 degrees. Am I correct in my assumption? If I need to replace the unit, is it common to get some kind of "credit" for a working unit that is too small?

Thanks for any help/advice.

I don't think they will give you credit for the OLD unit, if the new machine use the same freon they might give you some credit for that only... they must recover/ recycle the freon, there is reward up to $5000 if they release the freon into the air...
