About Calvert Mechanical Systems

Chris Lenhard formed Calvert Mechanical Systems as a Delaware corporation in 1991. The company was named in honor of Chris' paternal grandfather, Vance Calvert. To make it easier for consumers to understand our business model, we marketed our business as Calvert Heating and Cooling and we have recently become a part of One Hour Heating & Air Conditioning so that we can bring even more value to our customers.
