Rocky Top Air has always done a great job for me. This was not my first time using them. I have been using them for a few years now. They came out most recently for routine maintenance. Everything turned out fine. I stick with them because their pricing is fair and their customer service is excellent. When their technicians come out they are always prompt, polite and professional. They are able to assess any problems with my unit quickly and efficiently. Then they take the time to explain to me what they find with their assessment and also take the time to answer any questions that I may have. Their technicians are knowledgeable, trustworthy, courteous and professional. The experience from quote through to service and maintenance is excellent! So, if you need any work done with your heating or air conditioning do not have any hesitations about contacting Rocky Top Air! I will absolutely continue using them!
