Cotti-Johnson HVAC Inc. traces its origins to the postwar period, when Louis Cotti and Bill Laurence opened a shop focused on heating system installations during a surge in homebuilding on the South Shore. Gary Johnson joined in the mid-1970s, expanding the scope to include equipment sales and a stronger emphasis on commercial HVAC. Ownership changed in the following decades, with Johnson acquiring the company and later partners purchasing the business, while operations extended across Eastern Massachusetts to serve both commercial and residential customers. Today the company is based in Taunton, Massachusetts, and operates as a regional HVAC contractor serving Eastern Massachusetts. Its work has long involved engineering, construction, and installation of heating and cooling systems for both commercial and residential settings across the region.
