Indoor air quality and humidity control for Fenton, MO homes, Thomas Hoffmann Air Conditioning & Heating

Beyond the Thermostat

In the Meramec Valley, Humidity Is Half the Battle.

Fenton sits low along the river, and its homes, many with finished basements, feel it: muggy lower levels in summer, dry static air in winter, and AC systems working overtime to wring moisture out of the air. We treat humidity and air quality as part of the job, not an upsell, from right-sizing equipment so it dehumidifies properly to filtration and ventilation where the house needs it. Tom Hoffmann owns the company, and in the City of Parks, comfort indoors should match the quality of life outside.

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.

Real Questions

Fenton HVAC Questions

Do you offer emergency HVAC service in Fenton?

Yes, around the clock. Call (314) 471-7625 any hour, any day, and a live dispatcher takes the call and gets a technician dispatched.

Why does my finished basement feel muggy even with the AC running?

Common in the Meramec valley. Below-grade rooms collect moisture, and an oversized or short-cycling AC cools the air without running long enough to dehumidify it. The fix ranges from airflow and drainage corrections to right-sized equipment or dedicated dehumidification. We diagnose which one your house actually needs before recommending anything.

Can better filtration help with allergies and dust?

Often, yes. Upgraded filtration and proper ventilation reduce the dust, pollen, and humidity swings that make indoor air feel stale. We’ll assess the system you have first; many improvements work with existing equipment rather than requiring new gear.

Which brands do you service?

Trane, Carrier, Lennox, Rheem, Goodman, and the rest of the major names. New installations are Trane systems through our authorized dealership, with factory support behind them.

What areas near Fenton do you serve?

Valley Park, Sunset Hills, Crestwood, High Ridge, Arnold, and the greater St. Louis metro on both sides of the Meramec.

How long does a system replacement take?

Most are done in a single day, scheduled in advance, with the new system running before we leave.
