Harry Hartigan 1985

ABOUT MSC

Hartigan Refrigeration was founded in 1976 by a young service technician named Harry Hartigan, who still serves as MSC's president today. As the company grew, our early focus on gasoline vapor recovery refrigeration systems quickly expanded to include process cooling and HVAC.

 

In 1978, our name was changed to Mechanical Service Corporation to reflect Harry's vision for the company's future. MSC is now widely recognized as the go-to expert in complex system service, diagnostics, and installation in the Northeast and Mid-Atlantic Regions.
