Greg came to my house because my upstairs AC condensation line wasn't draining properly. He went in the attic and quickly found the problem. Apparently the builder of our house for some reason switched the pitch on the drain line so it made our secondary drain the primary. The problem with that is in the summer our drain pan would over flow when temps got into the triple digits and when it was super humid out. He also found that they had installed a broken pvc joint so it was leaking in two places. He got it all fixed and then I had him refill my freon. He did a great job and from now on I will call them when I need anything done to my ac units.
