Have you ever had to add refrigerant to the system?? Also, make sure the outside coil is clean. Wash it out with water to make sure the coils are clean! Hope this helps!

Thanks for the info. I got it all thawed out and I can hear things moving in the tubing between the house and the outside unit again. I have it running and it's cooling some, but not much. I'm pretty sure that the A/C guy is going to want to recharge the f**ker.

Any guesstimate on how much to put in an A/C system sufficient to cool a ~2500sq ft house with LOTS of Southern windows?
