James H.

Came out immediately after a time slot opened and fixed the AC issue.

Hector R.

Super Helpful and Honest Service

I called this company earlier today because I was having a bunch of issues with my HVAC system. They were incredibly friendly and walked me through troubleshooting step by step over the phone. They didn’t even charge me for the call. Thanks to their honest advice, I was able to get things running smoothly again. Really grateful for their help and would definitely recommend them if you want straightforward and trustworthy service. Five stars all the way!

Mr T.

Giovanni the service technician was the best! Very knowledgeable, efficient and did a professional job replacing my hot water heater. I would highly recommend them to anyone in need of plumbing/ HVAC work first rate customer service at a very competitive price!

I called on December 25th at midnight and started leaving a message and Thomas Hoffman the owner called me back almost immediately. He said he would come out the next morning between 8:00 and 10:00 am snd he was promptly on time. He fixed my problem and while he was there I decided to get an estimate for a new furnace and air conditioning unit. The price was very reasonable and the installers one of them being his son were both very professional very courteous, polite, arrived on time and finished the same day. I enjoy knowing that I now have the support of Thomas Hoffman heating and air conditioning along with the peace of mind that comes with owning a Trane. Nothing stops a Trane.

The Thomas Hoffmann team did a great job taking care of our semi annual HVAC maintenance. They not only worked with us to schedule the visit, but also did an excellent job sending us reminders on when they would be out.

Layton M.

Nick was excellent. Super profession, quick, and up front with the pricing (which was fair). Hopefully we don't need to call anyone to fix our AC again, but if we do - I'm calling Nick!

Thomas Hoffmann is the most professional and courteous of all the HVAC companies in St. Louis. It has kept my HVAC systems in good working order through the hottest and coldest days for many years.

darlene T.

I notified two companies at the same time regarding a malfunctioning AC unit and Wow! Super fast response from Hoffmann on a weekend no less, to fix our AC unit. Hoffmann’s tech responded to my call immediately and fixed our AC before Galmiche has even responded. Used to be a Galmiche customer, but will use Thomas Hoffmann from here on out!

Thomas Hoffmann Air Conditioning & Heating specializes in installing, repairing, and maintaining the cooling system for your home. We are dedicated to keeping our customers cool in the hot summer months by selling the best air conditioners on the market, providing preventative maintenance services, and sending out our certified technicians to service your existing equipment.

Your air conditioning system is more than just a machine that keeps you cool when it’s hot. It should be reliable, lower your energy costs, and maximize efficiency. When you schedule preventative maintenance from Thomas Hoffmann Air Conditioning & Heating, we will protect your investment and ensure long-lasting comfort and reliability all summer. Annual service is essential for your cooling system’s performance and continued operation.

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

Air Conditioning Maintenance

Regular maintenance of your current AC unit is vital to the system’s performance. When the filters, coils, and other components are regularly checked and maintained, your system will function effectively and efficiently.

Although we are a Trane Authorized Dealer, Thomas Hoffmann Air Conditioning & Heating can repair and maintain any air conditioning system. With over 30 years in St. Louis, we have hands-on experience working with popular manufacturers like Trane, Lennox, American Standard, Carrier, York, Amana, Goodman, and more.

AC Repair

No matter how hot it is outside, your AC system should be at its best. However, St. Louis summers can put your air conditioner to the test. At Thomas Hoffmann Air Conditioning & Heating, we know how inconvenient and uncomfortable it is when your air conditioner stops working, especially in the middle of a heatwave.

Call us if your AC system goes out or isn’t blowing out cold air! Our 24-hour emergency repair service ensures that you stay cool in the summer and warm in the winter.
