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!

Common Questions

Frontenac HVAC Questions, Answered

How fast can you get to a home in Frontenac?

Our shop is in Des Peres, just minutes from Frontenac. We answer calls 24/7 — for urgent heating or cooling failures, call (314) 471-7625 and we’ll dispatch a technician as quickly as possible.

Do you work on larger custom homes?

Yes. Many Frontenac homes have multiple zones, multiple systems, or higher-end equipment, and sizing matters more as square footage grows. A Master HVAC Engineer leads our team, so complex layouts and multi-system homes are diagnosed and sized correctly the first time.

Do you service commercial spaces in Frontenac?

Yes. We service commercial HVAC systems for businesses in Frontenac, including offices and retail along the Lindbergh Boulevard corridor, and can schedule work around your business hours whenever possible.

Do you service all HVAC brands?

Yes. We repair and maintain all major brands including Trane, Carrier, Lennox, Rheem, Goodman, and more. As an authorized Trane dealer, we also offer new Trane installations with full manufacturer support.

Should I repair or replace my system?

We’ll give you an honest answer based on the age of your system, the cost of the repair, and its efficiency. A general rule: if the repair costs more than half the price of a new system and the unit is over 10 years old, replacement usually makes more financial sense.

What areas near Frontenac do you serve?

We serve Frontenac and the surrounding communities including Ladue, Huntleigh, Town and Country, Des Peres, Creve Coeur, Kirkwood, and the greater St. Louis metro area.
