I had my ac replaced by another company and there was a leak in my evaporator. They were going to charge me $99 just to come out an $99 an hour after that while parts was still under warranty. I called Stuart hvac and they came out and took the evaporator to the manufacture and brought back a new one. They only charged me for the labor. My system uses the new freon and Stuart had to recharge my unit which took 10 lbs of freon and he only charged me for 1/2 of that because he said I was a new customer and he would very much like to keep me as a customer for any future hvac service I may need. I was very pleased with the service Stuart hvac provided. They are honest, professional and clean. Most contractors leave a mess and don't bother cleaning up, Stuart stayed late just to vacuum my carpet below the attic access, I told him not to worry about it but he insisted on allowing him to clean up.
