Thomas Hoffmann Air Conditioning | St. Louis | HVAC Company Near Me

How quickly can you respond to an emergency?

We answer emergency calls 24 hours a day, 7 days a week — including holidays. For urgent heating or cooling failures, call (314) 471-7625 and we'll dispatch a technician as quickly as 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.

What's included in a maintenance tune-up?

A standard tune-up includes inspection of all electrical connections, refrigerant levels, coil cleaning, thermostat calibration, filter check, and a full system performance test. We'll flag anything that needs attention before it becomes a breakdown.

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 do you serve?

We serve the greater St. Louis metro area including Chesterfield, Ballwin, Kirkwood, Webster Groves, Creve Coeur, Manchester, Maryland Heights, Des Peres, and surrounding communities.

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.

Why choose Thomas Hoffmann over a national chain?

Many national HVAC brands operating in St. Louis are franchise operations — not true local companies. Thomas Hoffmann is locally owned, and Thomas himself remains directly involved in every job. You get a Master HVAC Engineer's expertise, not a call center.

How long does a furnace or AC installation take?

Most residential installations are completed in a single day. We'll give you a clear timeframe before we start and keep the work area clean throughout. Our goal is to have your system running before we leave.
