Full Charlestown NH HVAC Services for Every Season

Across Charlestown, New Hampshire, Bergeron Mechanical Systems designs Mitsubishi Electric mini-split and heat pump systems that deliver heating and air conditioning year-round. Mitsubishi Electric is the only brand we install. Each project is tailored to the home in front of us, whether you're upgrading an older system, replacing tired equipment, or building new construction comfort from scratch.

Mitsubishi Electric Mini-Split Systems

Mitsubishi Electric mini-splits provide year-round heating and cooling with a single ductless system. Indoor units come in a range of formats: wall-mounted, floor-mounted, ceiling cassette, and ducted, so each installation fits the home it's going into. Quiet performance, smart control, and reduced energy usage are built into every Mitsubishi Electric mini-split.

Mitsubishi Electric Heat Pump Systems

A Mitsubishi Electric heat pump transfers heat from one place to another. Instead of generating warmth, the system moves it: indoors when the home needs heating, outdoors when the home needs cooling. That heat-transfer technology is the reason a Mitsubishi Electric heat pump uses less energy than traditional heating systems and runs quietly through every season.
