0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.
Response from the owner:Hi there. I am unable to locate your customer profile. Please give our office a call at 314-471-7625 so we can get this figured out for you.

Got a quote over the phone. Everything was explained thoroughly. Dakota, my technician arrived and on time, was very professional and knowledgeable. He didn’t try to upsell or change anything. He did a great job. We can already tell the difference since the ducts and vents were cleaned. Would recommend an use Hoffman again in the future.

Common Questions

Frequently Asked Questions

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 Technician’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.

Ready to Schedule? We Answer 24/7.

St. Louis homeowners have trusted Thomas Hoffmann for over 30 years. Local ownership means you deal with real people — every time you call.
