The repairman arrived at around 8:30 AM and spent about three hours working on the unit, which I purchased from them less than a year ago. At the end of three hours, he informed me that my unit was not working because I had the wrong filter in it. I raised a question about why it took three hours to replace the filter. I can't really explain his response because it was in technical jargon that I did not understand well enough to know what other questions to ask. The unit has a two year parts and labor warranty and a 10 year manufacturer parts warranty. unfortunately, I did not get the benefits of those warranties because, as the technician put it, the onus for using a less effective filter, rests with the customers. Then, he went on to describe to me the best filter choice, something the average customer would not automatically know. My greatest disappointment was being denied the benefits of my warranties. On the plus side, once management became aware of my dissatisfaction, they reached out to me with an apology for any role they played in my dissatisfaction and, as a show of their good intentions, they shredded my check, subsequently, not charging me for their service. This response showed a genuine commitment to quality and efficient service, as well as a commitment to customer satisfaction. Consequently, I highly recommend Hoffmann Air Conditioning services.
Response from the owner:Thank you, James, for your 5-star rating; we truly appreciate your support!

I was distraught to find out our 20 year old HVAC needed to be replaced. Hoffman was beyond empathetic and took care of me within 24 hours during the heat wave. They were on time and very efficient. I have to have trust worthy people work on our house and be in our cocoon, therefore Hoffman has always been our contractor and always will be! They have become family;) I refer all of my clients to them!!!

Technician, Giovanni Leone, did such a great job in fixing our AC on a Saturday morning when the Temp is supposed to get up to 100 degrees, later today! I felt like we were in excellent hands and he explained everything he was going to do and then explained in even greater detail once everything was done! I told him if he ever wants to go into sales, he should! He has great personable skills! We have used Thomas Hoffmann before for our heating and cooling needs and they are always professional and trustworthy! My only mistake was not having them to come out to check our AC in the past 3 years!
Response from the owner:Thank you, Bill! We're so glad to hear about your positive experience with Giovanni. It's great to know that you felt well taken care of and appreciated his thorough explanations. We truly value your trust in us for your heating and cooling needs, and we look forward to serving 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.
