One Hour Heating and Air Conditioning came out and reprogrammed our thermostat. We had tried everything and it wouldn't respond to anything we did. While the technician was here he also recharged the system with freon and replaced the capacitor. He was very clean in his work and explained the whole process. I have used them before when they installed this unit in my home and I would recommend them to anyone who needs their services. I appreciate them and the work they do!
