Kohnen Air Conditioning & Heating
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. Soon Gerry met his life-long wife and sound business partner, Ann. The business soon once again found itself on the move when ground was purchased and a building was erected at 1104 Sycamore St. in Germantown (the current location).

We have used Kohnen over 23 years. They are A+++++ excellent in our book .When we were building they won our confidence in that i talked with Ryan’s dad if we shld add more to our system. He commented i wld love to sell u more but with the Atrium house the heat wld go right up the staircase. Thats when we knew we had a 100% reputable family to take care of our needs. Ryan has given us his cell and home number because he cares that we are 109% Satisfied.
Ryan and a helper came in last week and cleaned our duck system. My husband and I neither getting up and sneezing, which is proof in the pudding

The Kohnen guys are great. They called ahead and were very punctual. They were very friendly and knowledgeable about their work and products. I believe the price was very reasonable and I feel I can depend on them if I have any issues.
