  • “Interstate AC is prompt, courteous, and professional! From dispatch to the service technicians, they get the job done as quickly as possible without cutting corners. I use their commercial division and can tell you that if their residential side is anything like the commercial side, you won’t be dissatisfied.”

    -Brian K.
  • Could not have been more pleased with the service we received from Jeff. He came out on a Sunday, then returned on Monday to further troubleshoot the issues in one of my commercial establishments. Was able to get us back up and running quickly. Highly recommend you give the good folks at Interstate a call for ALL your heating and cooling needs in the Nashville area.”

    -Steve C.
  • “We have used Interstate AC Service for more than 20 years. They have always provided reliable and professional service, whether it is for a repair or the installation of new units. They are quick to respond to our request for service and their staff are always friendly and professional.”

    -Kathryn S.
  • Friendly service, both on the phone and in-person. Ben (the service tech) was great and was happy to answer my technical questions as he diagnosed the system. He was very thorough in confirming everything was working correctly before leaving. Will definitely continue to do business with them.”

    -Swede R.
  • “I called this morning for an immediate need (same day) and they were able to accommodate. Everyone was amazing to work with, from scheduling with reception to the technician. Very prompt and polite. I will definitely be using this company for future services. Thank you!”
