After an unfortunate interaction with a different heating and air company(see my review for Southern Home Performance), I had Jones Heating & Air come out to look at the problem. I contacted them specifically because I knew they had experience with my type of antiquated system(AquaTherm). He was able to work around my schedule, come out, and fix the A/C problem that very day. After my experience with the first company, I was shocked that it was that simple(and relatively inexpensive)!
