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.

Before You Call

Webster Groves HVAC, Explained

Do you handle HVAC emergencies in Webster Groves?

Any hour, any day. If the heat or AC gives out, call (314) 471-7625. A live dispatcher takes your call, weekends and holidays included, and dispatches a technician as fast as scheduling allows.

Are replacement estimates really free?

Yes. If your system is at the end of its life, we’ll evaluate the house, size the replacement properly, and put a number in writing at no charge. No obligation and no pressure to decide on the spot.

Can you service the older homes in Old Webster and Tuxedo Park?

That’s some of our favorite work. Century-old houses often mean undersized ductwork, add-on cooling, and mechanical rooms that were never designed for modern equipment. We plan around those constraints instead of forcing a one-size-fits-all install.

What brands do you work on?

Trane, Carrier, Lennox, Rheem, Goodman, and just about anything else in a Webster Groves basement or side yard. New installations come through our authorized Trane dealership with full factory backing.

Which nearby areas do you also serve?

Alongside Webster Groves we cover Kirkwood, Glendale, Rock Hill, Shrewsbury, Brentwood, Crestwood, Maplewood, and the rest of the St. Louis metro.

How disruptive is a full system replacement?

Less than most people expect. The typical changeout wraps in one day, we protect floors and work areas, and you’ll know the schedule before anyone shows up. The goal is heat or cool air flowing before the truck leaves.

Webster Groves, Your Comfort Call Is One Number.

Locally owned, 30+ years of St. Louis HVAC experience, and a dispatcher who answers around the clock. That’s the whole pitch.
