After our AC gave out in 106 degree heat, Bill showed up on a Sunday afternoon even though he had many dozens of other service calls he needed to make just to come by to see if he could find the problem. He was able to diagnose and repair the bad capacitor in no time and recharge the system with new refrigerant so everything is now working at 100% capacity. How many service people show up just because they were in the area and just wanted to help?
I will never go to anyone else for help with our HVAC needs.
