 About

"Although pronounced “GEM” and phonetically incorrect, JEM represents the initials of my three sons, Jeffrey, Eric, and Matthew"…Mike Cote, owner.

JEM was established on February 19, 1997. Armed with only a pick up truck, a handful of tools, and a dream, we set out to develop a Company that would deliver quality craftsmanship, prompt service, and reasonable prices.

While the Company has grown over time, our dedication to customer service remains unchanged. Rest assured that we promise to fulfill your heating and cooling needs with uncompromised honesty, integrity, and expediency.
