Heat Pump Installation in Chesterfield, NH

A heat pump moves heat instead of generating it, which is how one Mitsubishi Electric system handles both your winter heating and summer cooling. For New England winters specifically, we install the Mitsubishi Electric H2i Plus, engineered for cold-climate performance and rated to hold full heating capacity down to -5°F. That means high-efficiency performance year-round and reduced dependence on fossil fuels.

Sizing for Chesterfield's Climate

Before we install anything, a Design Consultant comes to your home to measure how much heating and cooling it actually needs. That means looking at insulation, how much sun your windows get, the layout, and the size. Get that step wrong and the system either can’t keep up on cold days or runs nonstop on mild ones. It’s a big reason 9 out of 10 HVAC installations end up done incorrectly.

Ductless & Mini-Split Options

If your home doesn’t have ductwork, Mitsubishi Electric mini-splits are a direct alternative. Each indoor unit heats and cools its own zone, so you can keep bedrooms comfortable at night without running the whole system all day. Wall-mounted, floor-mounted, and multi-zone setups are all available.

The Monadnock Region's Only Mitsubishi Electric Diamond Elite Contractor

Bergeron Mechanical Systems holds Mitsubishi Electric’s Diamond Elite Contractor designation, and the brand has also recognized us as a Top Contractor nationwide for things like installation quality, materials, and low warranty claim rates. If you’d like to see systems in person before deciding, our showroom, The Comfort Zone, is in Keene.

How Heat Pump Installation Works

Free Design Consultation

A Design Consultant comes to your home to understand your comfort needs. We walk through each room together, look at your current heating and cooling setup, and go over which parts of the house aren’t feeling right. The visit is free and there’s no pressure to move forward after.

Personalized Design

Once the walkthrough is done, we design a system around your specific home. That covers which rooms should have their own zone, where the units go, and which Mitsubishi Electric configuration fits your layout. Every design starts from scratch for your home.

Advanced Heat Pump System Design Software

Heat load software handles the sizing calculation. Insulation, window exposure, how each room gets used, and square footage all feed in. The result is a system size tied to what your home actually needs.

Transparent, No Hidden Cost, Proposal

Before install day, you get a written proposal that covers the full scope of the work. Equipment, timeline, warranty coverage, and everything on our end are all in writing. If anything comes up during install that would change the plan, we stop and check with you first.

Precision Installation

We install every system to Mitsubishi Electric’s exact specifications. That covers the pad, the mounting, the electrical connections, and where each component is placed. Being a Diamond Elite Contractor means the crew on your job has trained specifically on this equipment.

Final Testing & Optimization

Once the system is in, we run the full setup end to end. That means checking each zone for heating and cooling, verifying airflow across the units, and confirming every control responds. Then we fine-tune the settings before calling the job done.

Ongoing Support & Maintenance

Your 12-year parts-and-labor warranty on all Mitsubishi Electric related components starts on install day. Any maintenance or service that comes up later, we’re the ones to call. Because we installed the system, we know how it’s set up down to the details.

A heat pump only performs as well as the installation behind it. Bergeron Mechanical Systems has been installing Mitsubishi Electric systems across NH and VT for more than 50 years and is a Diamond Elite Contractor.

Who Are Heat Pumps For?

Heat pumps are a good fit for homeowners in a few common situations. Some are moving away from oil or propane heat. Others are adding cooling to a home that doesn’t have any today. And some are replacing a heat pump that’s reached the end of its run. In every case, the upside is the same: one system that handles heating in the winter and cooling in the summer.

The winter question comes up a lot. Mitsubishi Electric’s H2i Plus is built for cold-climate performance and holds full heating capacity down to -5°F, which covers the coldest days around here.
