[QUOTE="scott024, post: 3761772, member: 34990"] Is the outside unit fan running? If it's not running or not running fast, it might not be able to cool the condenser adequately. Hopefully it's this and you only need a capacitor or a fan motor. These are easy to change out even if you've never done it before. There's probably 10 videos on Youtube on how to do it. I had a rent house with a similar problem and the duct had separated between the air handler and the vent. It was letting in hot air from the attic into the duct work. Might be worth a look if you were checking a vent in the ceiling. Other possibilities are that it could be low on freon. 19 years old, probably an R22 system. Probably not something you are going to be able to check unless you have a set of gauges. Should be some info on high pressure/low pressure operating ranges on the outside unit. It's an easy fix, but the HVAC companies are going to hit you with a diagnostic charge and then about 100-200/lb for the R22. Worse case scenario is that the compressor is on it's way out. (not likely, but it's a possibility). I'm not sure how you can check this and be absolutely sure that's what the problem is. [/QUOTE]
