    I had my HVAC unit go out at 8:30pm on a Saturday night. I called John H. Coleman and they had a guy there within the hour. He fixed the problem in 30 minutes and had my AC running! Thanks to John H. Coleman I didn't have to sleep … More in an 85 degree house that night. I now have them service my primary residence and my rental property. Go with John H. Coleman they won't let you down!

    In the midst of a funeral with family coming in from out of town, our HVAC unit stopped working. The JHC team responded quickly and got us back running with a new quality unit. We’ve used JHC for over 20 years, both for new unit installs … More and comfort care maintenance. They provide quality design, proper installation, and effective follow up. More importantly, they are a company with character.

    After dealing with many HVAC companies in Knoxville, I will never use anyone other than John H Coleman going forward. Chris the salesman was very professional and responsive. He got me a quote within a day and had me an appointment set … More up to change out the entire unit the same week. The two gentleman that arrived, arrived when they said they would and they were very professional and nice to work with. I was very impressed with the company’s communication, professionalism, and service. Would highly recommend!

    Very happy with our new AC unit from John H Coleman Co. The equipment is a great quality at a fair market value. The service from the first diagnosis inquiry, to the detailed information for the options we could select and to the installation, … More all members of the staff had been friendly and professional. When they ran into an unforeseen issue they handled it with integrity. We highly recommend John H Coleman Co and will use them again as needed in the future.
