R.A. Hoy installed my complete heating and air system and I was very happy with the quality of the installation. What I am not happy about is the price ($114.76) they charged me to install a defective thermostat that they installed and under warranty. Also they have had many other customers that have had problems with this same thermostat. I understand paying for the service call. To me it should have been a recall on the thermostat. I think the amount I paid for the service call should have been the total cost. Other than that I like the company and they do good work.
