About Us

Grogg’s Heating and Air Conditioning, Inc. was founded in 1970 by Leon B. Grogg. Although it began as a part-time venture, it quickly became a full-time business in which Leon spent many years serving the people of the Parkersburg area. Leon Grogg loved his business and was passionate about serving his customers with great honor and respect.

In 1996, Leon’s daughter and son-in-law Carma and Tim Hanlon purchased the company from Leon. While they were new owners of Grogg’s Heating and Air Conditioning, they were no strangers to the business: Carma grew up in the heating and air conditioning business working closely with her father for many years, and Tim also had the opportunity to work alongside Leon, learning all aspects of the business.

In September 2005, Grogg’s opened a branch in Clarksburg, West Virginia which Leon’s grandson, R. Keith Blair manages. Because of the tradition of excellent customer service, the steady growth also allowed for the acquisition of three other successful HVAC businesses. Grogg’s Heating and Air Conditioning, Inc. is now one of the largest and most successful HVAC companies in the state. However, faithful to their humble beginnings, they guarantee the same unmatched customer care that Leon was passionate about.
