In 1954, Louis Cotti purchased the remainder of the company from Bill Laurence, and ran the company by himself until the mid-1970’s, as the premier heating & cooling contractor on the South Shore.

Gary Johnson entered the company in the mid-1970’s, and introduced the Equipment and Commercial side of the business as his background was Equipment Sales. Louis and Gary expanded their Commercial Focus as the South Shore experienced growth of population bringing all sorts of Businesses needing heating & cooling services.
