Albert K.

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.

I made another service call years after my last review. Once again, Tom did not disappoint. He identified the cause of my newly purchased system installed by another HVAC company. He explained it so simple and easy to understand without the technical jargons. I just wished I had purchased the new equipment from Tom instead of saving a few hundred dollars from his competition.

Thomas Hoffmann always does a great job in servicing our HVAC. Installed a new system last and it’s working great and very efficient. Nick goes above and beyond when servicing and answers all my questions. Highly recommend Thomas Hoffmann Air conditioning & Heating.

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.
