Thomas Hoffmann Air Conditioning & Heating, locally owned HVAC company serving Hazelwood, MO

Independent and Accountable

The Name on the Company Answers for the Work.

Plenty of familiar HVAC names around St. Louis are now owned by out-of-state corporations, even when the trucks look the same as they always did. Thomas Hoffmann Air Conditioning & Heating is still independent and locally owned. Tom sets the standards, the technicians are our own background-checked employees, and every recommendation in a Hazelwood home has to pass one test: is it what we’d do in our own house?

Local

Independently Owned

30+

Years in the Trade

Master HVAC engineering experience applied to everything from 60s-era ranch ductwork to modern high-efficiency systems.

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 Call

Hazelwood HVAC Questions, Straight Answers

Do you offer emergency HVAC service in Hazelwood?

Yes, around the clock, weekends and holidays included. Call (314) 471-7625 and a live dispatcher gauges how urgent it is and gets a technician assigned as quickly as the schedule allows.

Can you work on the original system in an older Hazelwood home?

Yes. Much of Hazelwood’s housing dates to the 1950s through 1970s, and we work on aging equipment and ductwork every week. If a system is on borrowed time, we’ll say so plainly and price the repair next to a replacement so you can compare.

What brands do you repair?

All the major names, including Trane, Carrier, Lennox, Rheem, and Goodman. For new installations we’re an authorized Trane dealer with factory support behind every system.

How often should my HVAC system be serviced?

Twice a year is the general rule: cooling in spring, heating in fall. Regular tune-ups help maintain efficiency, keep manufacturer warranties valid, and often catch small problems before they turn into weekend emergencies.

Which areas near Hazelwood do you serve?

Florissant, Bridgeton, Maryland Heights, St. Ann, Berkeley, Ferguson, Black Jack, and the rest of the St. Louis metro.

Should I repair my old AC or replace it?

It usually comes down to the size of the repair against the age of the unit. A minor fix on a mid-life system often makes sense; a major component failure on a 15-year-old unit usually doesn’t. We put both numbers in front of you and let you decide.
