    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.

    My wife used JH Coleman long before she and I met in 2000. We’ve since used JHC to service our 2 AC/Heat units, we even signed up for the yearly checkups in both fall and spring. And even though the units were old, they always kept them … More running, and never tried to talk us into replacing them. They’d repair them and didn’t ever pretend there was more issues than what was needed. That alone made us loyal customers!
    But a few months ago as I walked past our oldest unit I could smell gas, and even though my wife and I weren’t really ready to replace either one of the units, we weren’t about to take any chances. So we called JHC and set up an appointment to get prices on 2 new units.
    Then about a week later their crew was here bright and early (in pouring rain) and removing the old units and replacing them the SAME DAY. We love our 2 brand new Lenox units, and they’re kicking butt. Thank you John H Coleman! You guys are the best, and our home is warmer and cooler than ever.
    You can trust this company. Promise.

    We contracted John H Coleman to remove and replace the ductwork in our crawl space. The project was attached to a loan package we were using to purchase a new home. This involved a fair amount of paperwork and the bank required us to go … More back multiple times for additional paperwork and information from John H Coleman.
    We worked with Chris throughout the process and he was ever friendly, helpful, and patient. Even when the request from the bank had gone way past the point of ridiculous.
    The crew showed up on time and ready to go. Everything with these guys was smooth and efficient. Very professional. We would gladly work with them again.
    Thanks Chris, and everyone at John H Coleman's, for all your persistence and assistance.
