    We have used John Coleman for 44 years. They installed our units, three of them, and have checked them spring and fall. Recently a new H/A unit was installed. It was completed efficiently, professionally and neatly. We have high regard … More for their integrity and commitment to service and quality!

    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.

    Great experience; an unexpected issue was resolved quickly, everyone was on time, communicative, friendly & professional. Cleaned up and left no trace except for blessed cool air. They went above and beyond several times during install … More as the old system had made a quite a mess. New system works perfectly, I love it! Outstanding customer support and product, 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.
