Complete Dunbarton NH HVAC Services

Bergeron Mechanical Systems serves Dunbarton, NH families with Mitsubishi Electric mini-split and heat pump installations, the systems we rely on for year-round heating and air conditioning. We work exclusively with Mitsubishi Electric, designing each setup around the home it's serving. The goal is the same on every project: comfort shaped to the home, with high-efficiency performance built into the system.

Mitsubishi Electric Mini-Split Systems

Mitsubishi Electric mini-splits are ductless heating and cooling systems built around one idea: year-round comfort from a single installation. The systems run quietly, deliver smart control year-round, and use significantly less energy than traditional HVAC equipment. Optimal performance comes from a Mitsubishi Electric mini-split designed around the home.

Mitsubishi Electric Heat Pump Systems

A Mitsubishi Electric heat pump moves heat. It doesn't generate it. The system transfers warmth from one place to another, in either direction, depending on what the home needs. Because heat is being moved rather than produced, a Mitsubishi Electric heat pump operates quietly and cleanly with reduced energy usage built into how it runs.
