Keller Heating Air Conditioning, Inc. began quite humbly on the corner of 8th and Rogers in Bloomington in 1972. Charlie and Sharon Keller started the business and have built it to what it is today. It started as a 1 man shop. It now employs 20 people ranging from service techs, installers, sales and office staff. The goal then and still today is to provide area families with comfort solutions that fit not only their lifestyle, but their pocketbook. After all these years, that remains to be the goal and be assured that their son, Greg, will continue the tradition for many years to come.

Family owned and operated, Keller Heating and Air Conditioning strives to serve Monroe and surrounding counties. Quality service, installation and repair are what Keller Heating stands for. Our fleet of trucks are instantly recognized and the customer is reassured that a trustworthy, factory-trained Keller technician has arrived.
