Full Amherst NH HVAC Services for Every Home

For Amherst, New Hampshire homeowners, Bergeron Mechanical Systems installs Mitsubishi Electric mini-split and heat pump systems that handle heating and air conditioning year-round. Mitsubishi Electric is the only brand we work with, and every install is designed around the home it's serving. From upgrading an older setup to a brand-new install, the systems we install deliver Smarter Energy Performance season after season.

Mitsubishi Electric Mini-Split Systems

Mitsubishi Electric mini-splits provide year-round heating and cooling from a single ductless system. The technology combines quiet performance with smart control and reduced energy use, so the home stays comfortable year-round without the noise or inefficiency of traditional HVAC equipment. One Mitsubishi Electric system, two functions, designed around how the home is used.

Mitsubishi Electric Heat Pump Systems

A Mitsubishi Electric heat pump doesn't generate heat. It moves it. Warmth gets transferred from one place to another, into the home for heating and out of the home for cooling. The technology behind it is what makes a Mitsubishi Electric heat pump quiet, clean, and significantly more efficient than traditional heating systems.
