We preferred going with a local company so we recently tried calling Carbon Valley Heating & Air. We see their trucks around town all of the time. This was our first time using them and we would definitely recommend them to people. The office staff was very quick to respond when we called for an appointment. The technicians came out and cleaned the furnace and the vent system. They were both very cooperative and friendly. We were very pleased with Carbon Valley Heating & Air and plan on using them again.
