Rocky Top Air gives me the peace of mind to know I can call them at any time and they will respond quickly. I have a maintenance contract with them and they have been great. Someone else installed a system that had been giving me a lot of problems. Rocky Top Air came out and did not give up until they had it running perfectly. They were very professional and put shoe covers on every time they came into my home. I will be keeping the maintenance contract with them, it is money well spent.
