Common Questions

Des Peres HVAC Questions, Answered

How fast can you get to a home in Des Peres?

Our company is headquartered in Des Peres, so response times here are typically among the fastest in our service area. 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.

Where is Thomas Hoffmann Air Conditioning & Heating located?

We’re based in Des Peres, Missouri, and serve the greater St. Louis metro area from here — including Kirkwood, Ballwin, Manchester, Creve Coeur, Town and Country, and surrounding communities.

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.

Yes. We answer emergency calls 24 hours a day, 7 days a week — including holidays. A real St. Louis dispatcher picks up the phone and gets a technician moving as fast as possible.

Why is my AC blowing warm air?

The most common causes are low refrigerant, a dirty air filter, a tripped breaker, or a failed compressor. Some are simple fixes; others need a technician. If your AC is running but not cooling, call us — we’ll diagnose it accurately on the first visit.
