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!
Excellent service and a job very well done. Highly recommended!

Common Questions

Kirkwood HVAC Questions, Answered

How fast can you get to a home in Kirkwood?

Our shop is in Des Peres, which borders Kirkwood — 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.

Do you work on older and historic Kirkwood homes?

Yes, and it’s some of our favorite work. Many homes near downtown Kirkwood are 75 to 100+ years old, with boilers, retrofitted ductwork, plaster walls, and additions that each heat and cool differently. A Master HVAC Engineer leads our team, so we size and design solutions around the house instead of forcing a one-size-fits-all system into it.

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.

Do you offer emergency HVAC service in Kirkwood?

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.

What areas near Kirkwood do you serve?

We serve Kirkwood and the surrounding communities including Des Peres, Webster Groves, Glendale, Warson Woods, Oakland, Crestwood, Sunset Hills, and the greater St. Louis metro area.
