I had a great experience with Crossville Heating and Cooling. Most recently, the company installed a thermostat and I was more than happy with how the service went. This company installed a heating unit for me about 8 or 9 years ago. I would describe the employees as professional and friendly. Overall, I would probably recommend their service to other people and I would probably use them again for another service. The only improvement I can think of is that the people who work at the main building could do a better job answering the phone, because it was hard to get in contact with them.
