    John H. Coleman's Sales and Installation people did everything promised. from being on time, professional installation, and clean-up and haul away.
    Couldn't be more pleased. Plus, the A/C and heater work very efficiently and
    … More are QUIET!

    This was the best install experience I have ever had. Chris Foster did the estimate and left us feeling we had dealt with a real professional (compared to the other estimates we had) and the install crew were extremely professional in the … More way they worked and the respect they showed our property. They left the house as clean as it was when they started and the old system removal left the yard uncluttered. I would very highly recommend this company to anyone I know. Top notch people and service. Once again, the best I have ever dealt with.

    The upstairs system was on its last leg. Coleman replaced everything, including a portion of the duct work to increase flow, in 6 hours. The upstairs didn't get too hot because they started work at 8:00 AM.
    They even had to set
    … More a new foundation for the condenser unit which looks to be 3 times the size of the contractor's awful unit.
    Great quality, great service, everything very professional.
    I'm a retired EE and would highly recommend them to anyone.

    John H. Coleman has maintained my 30 yr old HVAC system for the past ten years. When my A/C compressor finally died, I was able to get a quick response for a replacement from Chris. They showed up on time - took out the old furnace quietly … More and efficiently from the attic on a 90+ temp day - cleaned up and finished in under 6 hours. They even provided a window A/C unit so we could sleep in our bedroom until they were able to replace the unit.

    They provided my family with 5 ⭐️ service on the 4th of July. They got me up and running again within an hour! Good people, great service! Y’all are the best!
