Small City, Full Coverage

A Century of Brentwood Homes, One Standard of Work.

Off Brentwood Boulevard and Manchester Road you’ll find 1920s-40s bungalows, mid-century ranches, condo communities, and brand-new infill builds, often on the same block. Each heats and cools differently, and we service them all with the same approach: diagnose honestly, price in writing, fix it properly. Tom Hoffmann owns the company, not an out-of-state group with a friendly name, so the accountability is personal.

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!!!
Response from the owner:Thank you, Katie! We're so glad to hear that you felt supported during a tough time. Your trust means the world to us, and it's wonderful to know that we’ve become part of your family. We appreciate your referrals and look forward to continuing to serve you and your clients!

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 Book

Brentwood HVAC Questions

Do you offer emergency HVAC service in Brentwood?

Yes, every hour of the year. Call (314) 471-7625 and a live dispatcher takes the call, weekends and holidays included, and gets a technician dispatched promptly.

Do you service condos and townhomes?

Yes. Brentwood has a large share of condo and townhome living, and we regularly handle the compact mechanical closets, shared walls, and association requirements that come with those units, in communities like Brentwood Forest and elsewhere.

Can you work on both my old bungalow and my neighbor’s new build?

Yes, and in Brentwood that’s often literally the same street. Older homes tend to need retrofit thinking and careful sizing; new construction needs commissioning and warranty-conscious service. We do both daily.

Which brands do you repair and install?

We repair Trane, Carrier, Lennox, Rheem, Goodman, and the other major brands. For new installations we’re an authorized Trane dealer with factory support behind the work.

What nearby areas do you also serve?

Richmond Heights, Maplewood, Rock Hill, Clayton, Ladue, Webster Groves, and the greater St. Louis metro.

How long does a system replacement take?

Most are finished in one day. You’ll have the schedule before we start, the work area stays protected, and the system is up and running before we leave.

Brentwood Comfort, One Call Away.

Locally owned, 30+ years of St. Louis HVAC experience, honest written pricing, and a dispatcher who answers around the clock.
