About Us

Offering quality service, since 1915.

About Us

Founded in 1915, Belmont Engineering’s goal was to provide the people of Belmont and the surrounding areas with a company they could rely on for honest, professional help.

Since that time, Belmont Engineering has grown from a small residential service company to a large residential and commercial mechanical contractor. Today, several thousand satisfied customers are evidence that our company continues with that goal in mind.

We have led the way by installing the newest and most environmentally friendly heating and cooling products and continue to stay on the cutting edge of technology with 2-speed and variable-speed heat pumps, air conditioners and gas furnaces.

We are fully licensed and insured.

The Better Business Bureau (BBB) system in the U.S. extends across the nation; coast-to-coast, and in Hawaii, Alaska, and Puerto Rico. Since the founding of the first BBB in 1912, the BBB system has proven that the majority of marketplace problems can be solved fairly through the use of voluntary self-regulation and consumer education.
