The establishment of Sigma-Tremblay dates back to over a half a century ago when Jack and Ann Armstrong founded Sigma Environmental Systems in 1968. Through years of hard work and excellent customer service, Sigma became Dutchess County’s premier Carrier dealer. In 1986 John Tremblay began building his business with a partner. Their business continued growing until in 1994 when John Tremblay took over the business in full, thus creating Tremblay and Company. Soon after, following the same path as the Armstrongs, Tremblay and Company was the area’s principal heating, ventilation, and air conditioning servicer.

After over thirty years of fine service to the community, Jack and Ann Armstrong began to plan for their retirement. After looking at several offers, John Tremblay was selected to be their successor due to his proven commitment to customer service. By 1999 the companies were merged internally but they continued to operate independently from one another for almost three years. After ensuring a smooth transition for customers and staff of both companies, Jack and Ann retired; and in 2002 Sigma-Tremblay was officially born.

Today Sigma-Tremblay offers customers two enormous advantages; a combined tradition of more than five decades of quality experience, workmanship, and service as well as the choice between the finest heating and air conditioning equipment manufacturer in the world; Carrier. In addition to this, Sigma-Tremblay has been working with NYSERDA for over fifteen years, in an effort to bring cost effective energy saving options to people all over Dutchess, Ulster, Putnam and Orange Counties.

These licenses are reciprocal almost everywhere else allowing us to respond to calls all over the hudson valley and beyond.
