I am delighted with the service I received from the maintenance specialists while replacing the Thermocouple on my water heater. The work was done without issues and completed in less than 30 minutes. I will always recommend this company to anyone needing heating and cooling services. I would also like to mention how this company takes full accountability and responsibility if any repairs are not up to par. Not that I have had that experience. I read the reviews posted on BBB and was very impressed with how Thomas Hoffman and his team explained each situation and the subsequent resolution to the customer's satisfaction.

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

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.
