Everything starts with a Free Design Consultation in your home. We look at how you heat and cool each room today, take measurements, and run the load calculations that show what your space needs. From there we walk you through the Mitsubishi Electric system options that make sense for your home, and you get a Free Estimate before you commit to anything.
Once your design is set, our technicians handle the full installation. They take care with your home through every part of the job, and they don't wrap up until the system is tested and running the way it should. Before they leave, they walk you through how it works and leave your space clean.
Ongoing System Support
Even after your system is up and running, we stay close by. Bergeron Mechanical Systems supports the systems we install, so if a question comes up or you need service later on, you're working with the same team that put it in. We want it running well for you for years to come.



Bergeron Mechanical Systems is a Mitsubishi Electric Elite Diamond Contractor, the top of the manufacturer's certification tiers. It isn't something a company applies for; it's earned through ongoing factory training and a long track record of solid installations. For you, that shows up in the work itself: a system designed and installed to Mitsubishi Electric's own standards, a direct line to the manufacturer when technical questions come up, and a 12-year warranty on all Mitsubishi Electric components.
For more than 50 years, Bergeron Mechanical Systems has been a family-owned business serving homeowners across New Hampshire and Vermont. The same family that designs and installs your system will still be around to stand behind it, long after the work is done.
With one Mitsubishi Electric system, you get heating in the winter and cooling in the summer, no need for a separate furnace and AC. It works efficiently the whole year and fine-tunes itself room by room, so your home feels right no matter the month.
On every system we install, you get 1-year bumper-to-bumper warranty coverage of all parts and labor, plus a 12-year warranty on all Mitsubishi Electric components.

Highly recommended for heat pumps. From initial meeting with Monique we were given information and advice to get the best option for us. The installation team of John, Mitchell, Nils, and Lincoln were efficient and professional. They took care in our home and were friendly and helpful.
