Emergency Service

Thomas Hoffman air-conditioning and heating is so wonderful and professional! Nick Hoffman was the technician that diagnosed my malfunctioning air conditioning system and determined how to fix it. He was so incredibly professional and even invited me to watch while he worked, and kindly explaining to me all the details about the problem and how he is fixing it. I am now a client for life with this company because of how professional, knowledgeable, and a delight to work with they are! I want to add that they prioritized helping me on the same day that I called and even was a holiday (and 90 degree heat out!), so that is another outstanding Effort from this amazing company! Thank you so much.
They were able to come out quickly to help when our AC went down in the heat! They were prompt, kind, knowleadgable, explained everything easily in ways I could understand, fixed the issue, and made the experience so easy! I felt comfortable with the technican in and around our home working. Nick took the time to answer some questions about an unrlated issue while there. They will always be who we call for our heating and cooling needs!
I highly recommend Thomas Hoffmann for anything involving HVAC. The person replacing my furnace, Britton Buehrig, was Professional and took pride in his work. The job was very cleanly done.
Excellent service. AC went out on a hot summer day, hooked up with them through Angi, and within 2 hours they had arrived and fixed the problem. Can't ask for more than that
Nick Hoffman was great. He came short notice to fix a leaky air handler did it quickly and efficiently and also took a look at the AC plan on using them again for our service of our HVAC
Nick arrived to repair our ac earlier than expected. He quickly diagnosed and made the necessary repairs. The cost was reasonable. We will definitely contact Thomas Hoffmann for hvac services in the future..
We have used Thomas Hoffman Air Conditioning and Heating for AC issues for the last two years. We have been so happy with the service we have received both times. This year, we just needed a little maintenance as our unit wasn’t working to its full potential. I called first thing in the morning and was able to get a same day appointment! Nick was so personable and knowledgeable, and he got us back up and running and no time. Thank you again for saving us from the summer heat!! We are so grateful for the amazing customer service you guys provide!!!
I txt Thomas Hoffman air-conditioning and heating Sunday early evening about 6:30 and just left A detailed message of what was going on with my AC I received an automated reply, saying they would contact me soon. I heard from them the next Morning at 11 AM to confirm what was going on with my unit and said they would have a Tech out today still but would be the last call between 6 and 8pm. I expected to get an appointment 2 to 3 days later. We’re in the middle of about an 8 to 10 day Heat wave of Mid to upper 90s. So imagine my surprise when I received a call from Zachary at 3:20 telling me he was in Saint Charles and was on his way to my house to look at the unit. When I explained what was wrong on the phone, he was pretty confident. He knew what it was once he got here, pulled off the cover and sure enough it was the capacitor. Pull the old one off and install the new one turned it back on and boom I have cold air blowing. I would highly recommend Thomas Hoffman, AC and heating and if you can request a certain Tech Zachary is your guy he is great super Frndly got the job done quickly and even interacted with my dogs Who are super friendly
We can’t say how happy we are with the quick and efficient service! We came home Friday evening after work on a 95 degree day (with a week of 90 degree weather ahead) and our A/C was totally out. We called this small business owner around 6pm and he was here by 7:25. He replaced our wires, had cool air running, gave us some helpful tips for the future, and was already out the door by 7:50. He was very polite, friendly, straightforward, and saved our evening/weekend!
Tom & Nick have taken care of all our HVAC needs for multiple properties for over a decade. Great team.
We recently moved into an older home and had an issue with the AC not working. We called and were offered a same-day appointment. Nick was fantastic—very knowledgeable and professional. He quickly diagnosed the issue with the air handler and got it fixed, and also installed a new thermostat for us. He was honest and straightforward with his recommendations and never pushed unnecessary products. Highly recommend!
Excellent service. A/C went out on a weekend. Called them on Saturday morning, they were out within about 2 hours. The fix was easy enough, and he even had the part in the truck! I recommend this company for all of your HVAC needs
The service technicians are very courteous and communicate well with the customer. They let you know what, if any, problems are found, the options, and the cost of the repair(s). Quick and efficient.
Hoffmann came out the same day I called them because our AC was out. The technician, Ryan, was able to get the system running again, was polite and responded to my questions. We’re off to a good start!
We really trust Thomas Hoffman AC and Heating. Nick Hoffman has serviced our units several times now and he is professional, knowledgeable and very easy to work with. He comes on time, so we don’t have to schedule a long waiting period. We would highly recommend this company.
We’ve been looking for a locally owned small HVAC dealer for a few years. And we found it with Thomas Hoffmann Air Conditioning & Heating. We love their service technicians. They come on time, they know what they are doing, they don’t upsell you on every appointment and they like working for Thomas Hoffmann. A happy employee makes for a happy customer.
I called on a Monday morning as air conditioning was blowing warm air. They were able to come to my house very early afternoon and fixed the problem. Would highly recommend and will use them again.

Air Conditioning Service

Summers in St. Louis can be unbearable. Without a working air conditioner, the inside of your home can be miserable. Keep your family cool by scheduling regular maintenance visits from Thomas Hoffmann Air Conditioning & Heating.

Dirt and debris can build up at numerous points without an annual inspection. Mold spores, pollen, colonies of insects, and even decomposing rodents can result in bacteria being introduced into your home when summer temperatures rise. Also, dirt can significantly decrease your system’s energy efficiency. As mold, mildew, and dust accumulate, it covers the coils, preventing heat absorption. When airflow is restricted, condensation can freeze and completely block the coil. When the unit’s motors are overworked, they can cause wear and tear, quickly adding to costly repairs.

At Thomas Hoffmann Air Conditioning & Heating, we provide the following Air Conditioning Services:

  • Air Conditioning Maintenance
  •  Air Conditioning Repair
  •  Air Conditioning Installation
