We live in Dardenne Prairie, and want to thank Tom for his excellent work in assessing our A/C unit that stopped working over Labor Day weekend where the outdoor temps were 100+. Tom not only had the exact components on-hand but also offered other future solutions to make our home more comfortable. Very personable and professional! Thanks Tom!

I can’t say enough wonderful things about Thomas Hoffmann Air Conditioning and Heating! Nick came promptly, which was such a relief, and from the very beginning, he was personable, professional, and incredibly honest. After dealing with other companies, Nick’s honesty really stood out. He took the time to explain everything clearly, answer my questions, and make sure I understood what was going on—without any pressure or unnecessary recommendations. It was refreshing to feel like I was dealing with someone who genuinely cared about doing the right thing for the customer. Nick’s professionalism, knowledge, and customer service were truly top-notch. I wouldn’t hesitate to recommend Thomas Hoffmann Air Conditioning and Heating to anyone looking for a heating and cooling company you can actually trust!
Response from the owner:Thank you for the 5-star rating, Lori!

The service was excellent! When we arrived home after 8 pm, seen our unit was not working and it was almost 85 degrees in our home my husband began calling all of the companies that said they were 24 hrs. Thomas Hoffman heating and cooling was the only company that honored the statement. Nick was at our home in a very timely manor and was also able to fix our unit quickly! I would highly recommend to anyone needing any hvac services!
Response from the owner:Thank you, Morgan! We're glad to hear that you had an excellent experience with our service. It's great to know that Nick was able to assist you promptly and effectively. We appreciate your recommendation and look forward to helping you again in the future!

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.
