Professional Heat Pump Installation in New London, NH

Mitsubishi Electric heat pumps handle heating and cooling in one system because they move heat rather than create it. For the coldest stretches of a New Hampshire winter, we install the Mitsubishi Electric H2i Plus, which is rated to hold full heating capacity down to -5°F.

Homeowners get high-efficiency performance across the seasons and reduce their dependence on fossil fuels.

Proper Sizing for New London's Housing Stock

Every project starts with a Design Consultant on-site, measuring your home’s actual heating and cooling needs. Insulation, sun coming through the windows, the layout, and the size all get factored in. Miss this and the system will either fall behind when it’s cold or run when it doesn’t need to. That gap is why 9 out of 10 HVAC installations get done incorrectly.

Ductless & Mini-Split Configurations

When there’s no central ductwork in place, Mitsubishi Electric mini-splits give you an efficient way to add both heating and cooling. Because each indoor unit runs its own zone, you can prioritize the rooms you actually spend time in. Configurations vary depending on the room and the layout.

Bringing Diamond Elite Certification to New London, NH

Bergeron Mechanical Systems is a Mitsubishi Electric Diamond Elite Contractor, which is what the brand calls contractors that meet its training and installation standards. Mitsubishi Electric has separately recognized us as a Top Contractor nationwide for installation quality, materials, and low warranty claim rates. Our showroom, The Comfort Zone, is in Keene if you’d like to see systems in person.

Our Step-by-Step Installation Process

Free Design Consultation

The first step is bringing a Design Consultant to your home. They’ll walk each room with you, look at what’s currently in place for heating and cooling, and hear directly from you about what’s not working. There’s no charge for the visit, and moving forward is entirely up to you.

Personalized Design

Design begins after the initial visit. We work out the zones you actually need, decide where each Mitsubishi Electric unit belongs, and choose the configuration that matches your layout. Everything is designed for your home specifically.

Advanced Heat Pump System Design Software

System sizing runs through heat load software. Insulation, window exposure, how the rooms are lived in, and square footage all feed the calculation. The result is a system matched to what your home actually needs to stay comfortable.

Transparent, No Hidden Cost, Proposal

Ahead of any work, you have a written proposal that lays everything out. Equipment being installed, timeline, warranty coverage, and everything we’re providing are all documented. If we hit something on install day that would change things, you get a call before we do anything.

Precision Installation

Every install is completed to Mitsubishi Electric’s specifications. That covers pad work, mounting, the electrical, and every component’s placement. Our Diamond Elite Contractor status reflects specific training on this equipment.

Final Testing & Optimization

The system goes through end-to-end testing after install. Every zone is checked for heating and cooling, airflow is verified at each unit, and all the controls are confirmed to respond. Settings then get fine-tuned before the job is called done.

Ongoing Support & Maintenance

Install day marks the start of your 12-year parts-and-labor warranty on all Mitsubishi Electric related components. Whenever maintenance or a service issue comes up, you call us. We already know your system inside out because we installed it.

Most heat pump issues come from installation shortcuts, not from the equipment itself. Bergeron Mechanical Systems has spent more than 50 years installing Mitsubishi Electric systems across NH and VT and is a Diamond Elite Contractor.

Is a Heat Pump the Right Fit for You?

Heat pumps come up in a few different conversations. Homeowners transitioning off oil or propane. Homeowners who never had cooling and want it. Homeowners with a heat pump that’s aged past its useful life. In all three cases, what makes a heat pump attractive is that a single system handles heating and cooling across the whole year.

Winter always comes up. Mitsubishi Electric’s H2i Plus is built for cold-climate performance and holds full heating capacity down to -5°F, which covers the coldest weather around here.
