Kohnen Air Conditioning & Heating, Inc. was founded in 1973 by Gerald Kohnen. The business was started as a small one person shop in his parents, Aloys & Minerva Kohnen's basement. The business prided itself on providing personal and friendly service to a growing customer base. The business soon outgrew the boundaries of Gerry's parents basement and found a new home at the small building behind the old hardware center. The business continued to grow and new help was brought in to help meet the demand.

Our service department personnel are some of the most highly trained HVAC professionals in the industry. Each of our techs has a degree from Ranken Technical College in residential and commercial HVACR. Each technician continues to remain updated on the latest and greatest improvements made in the industry. Our technicians are trained to work on the smallest of residential systems as well as some of the largest industrial equipment. Specializing in commercial and residential service allows us to solve any problems you may have.

Kohnen Air Conditioning has grown into a commercial HVAC leader in the Metro-East area. The ability to design, build, and install commercial HVAC systems in house has made us a favorite contractor for many architects, engineers, and general contractors. We can offer the one stop solution for all of your needs.

When it comes to a new construction or a retrofit we are you solution. For over 35 years we have been installing and servicing residential central air conditioning systems. We provide systems that are not just slapped out and guessed at when it comes to size, we provide systems that keep efficiency and airflow in mind. Providing properly sized systems, we can help lower your bills and provide a comfortable environment. We offer classical central air systems as well as Geothermal solutions. Let us help you, we do not ever push a system on to you, we help you develop one that will meet your needs.

Our service department offers residential and commercial air duct cleaning as an option to our customers. This job is not something that is looked forward to nor enjoyed but we feel that as a provider of conditioned air to our clients, we must offer this. Throughout years of use air ducts become covered dust and grime. This can cause allergies, asthma, and not to mention a dirty house. We will use an industrial strength vacuum specially designed for cleaning ductwork to improve the conditions within your house.
