Tom was able to offer the solution to my hot water heating system that other major companies had not been able to figure out for years. It was a significant undertaking, but also very reasonable in price. Installers Nick and Chris are also very nice people to work with. The heat in our house now works better than it ever has.
Response from the owner:Thank you, James! We're glad Tom could provide the solution you needed and that Nick and Chris made your experience positive. It's great to hear your heating system is working better than ever!

Ryan has been a pleasure to work with. Unfortunately, to complete the installation of the contracted systems, there's still work to do getting the right vents in place, completing the thermostat placements, adjusting the airflow in the upstairs bedroom, etc. He's scheduled to come back next week and hopefully we can get this all finished.
Response from the owner:Thank you, Michael, for your feedback! We're glad to hear you've enjoyed working with Ryan. We'll make sure everything gets completed during his next visit.

Ryan arrived 20 minutes early. A great start to our day as we had a plumber coming today as well. They did overlap, but Ryan was thorough, efficient and gave us a clean bill of health on our furnace in about 45 minutes. WE LOVE THOMAS HOFFMANN AIR CONDITIONING AND HEATING. Oh and get the combo service plan for both your furnace and AC annual service. Very reasonable.
Response from the owner:Thank you for sharing your positive experience with our service technician! We appreciate your kind words and are glad to hear that you were satisfied with the service provided.

I highly recommend them!
