Customer Reviews

We’re Soaring To The Top Of The Charts!

  • The best part of the experience was Ryan’s knowledge and responsiveness. He answered all our questions in a courteous, professional, and timely way, and provided a competitive estimate. Isiah and Michael did the installation, and were fast, on time, and thorough.

    -Randy F.
  • “Isaiah and Mike did a great job! Both were very courteous and professional. Ryan showed up with some needed supplies and was also the same. Our airflow problems were fixed and we have a noticeable difference in our system’s operation. Highly recommended.”

    -Rick H.
  • “My technician Isaiah Barnes was punctual, polite, and professional. He answered all of my questions, and got my AC up and running. He even stopped back two weeks later to verify if the repairs he made solved the problem. Highly recommended.”

    -Thomas W.
  • I had a fantastic experience with this company, and I want to give a special shoutout to technician Michael. He recently replaced my HVAC filter, and I was thoroughly impressed with his professionalism and expertise. Quick service, and my system is running flawlessly. Highly recommend this company, especially thanks to Michael!”

    -Daniel B.
  • Shout out to Top Flight Heating and Air conditioning. Sunday we had no air conditioning and by Tuesday morning we were up and running. Michael and Ryan were very professional and on time. Love the quick response and communication with us, text and emails.
    Supporting Local! Would highly recommend.”

    -Robert H.
  • This whole experience was awesome! Ryan came on time, fixed every issue we had, and explained to us everything. We are first home buyers so the issues we’ve had to learn the hard way due to previous owner. Everything was fixed and we already felt a difference before he even left. Overall 10/10.”
