I have used Crossville Heating and Cooling for 27 years and they are a really good company. The were out here a few weeks ago to check out and clean both of our furnaces for us. One needed a new electronics board, and a fan. So, they took care of that. Like always, they did a great job for us. They are very nice people to be around, and very professional. They do what they need to do and they do it well!
