Heat Pump Installation for Hillsborough NH Homes

One Mitsubishi Electric heat pump handles both your winter heating and your summer cooling, because a heat pump moves heat rather than generating it. The Mitsubishi Electric H2i Plus takes that a step further with cold-climate performance and full heating capacity down to -5°F.

That translates to high-efficiency performance across every season and reduced dependence on fossil fuels.

Load Calculations for Hillsborough, NH Homes

Getting the right size takes an on-site walkthrough. A Design Consultant comes to your home to measure the real heating and cooling load, factoring in insulation, sun coming through the windows, the layout, and the size. If any of that gets missed, you end up with a system that can’t keep up when it’s cold or runs nonstop when it isn’t. Roughly 9 out of 10 HVAC installations get this part wrong.

Ductless & Mini-Split Options for Hillsborough Homes

Not every home is a fit for ducted equipment. Mitsubishi Electric mini-splits work without ductwork, letting different rooms run at different temperatures. Options include wall-mounted units, floor-mounted units, and multi-zone systems that cover several rooms from one outdoor unit.

A Mitsubishi Electric Diamond Elite Contractor Serving Hillsborough, NH

Bergeron Mechanical Systems is a Mitsubishi Electric Diamond Elite Contractor, meaning we meet the brand’s requirements for training and installation quality. Mitsubishi Electric has separately named us a Top Contractor nationwide, based on installation quality, materials, and low warranty claim rates. Our showroom, The Comfort Zone, is in Keene if you’d like to compare systems in person.

Our Heat Pump Installation Process

Free Design Consultation

The starting point is a Design Consultant visit. We spend time walking your home with you, seeing which rooms aren’t comfortable, and looking at how your current heating and cooling handles the space. The consultation is free, and you’re under no obligation afterward.

Personalized Design

Design work begins after the visit. We work through which zones your home needs, where the indoor and outdoor units should sit, and which Mitsubishi Electric configuration is the right match for your layout. Every design is built specifically for your home.

Advanced Heat Pump System Design Software

Sizing is handled by software built for load calculations. It factors in insulation, sun exposure through the windows, how the rooms are actually used, and square footage. That way the system is sized to what your home actually needs.

Transparent, No Hidden Cost, Proposal

Ahead of installation day, a written proposal lays out the full scope. Equipment, timeline, warranty coverage, and each part of what we’re delivering are all documented. Any change that would come up on the job gets flagged to you first.

Precision Installation

Installation is done to Mitsubishi Electric’s specifications, down to the detail. The pad, the mounting, the electrical work, and where each component sits all get handled to spec. Diamond Elite Contractor training means the crew knows this equipment specifically.

Final Testing & Optimization

After install, the entire system goes through testing. Every zone is checked heating and cooling, airflow at each unit gets confirmed, and every control gets a response check. Only after that do the settings get fine-tuned and the job wrapped up.

Ongoing Support & Maintenance

On install day, the 12-year parts-and-labor warranty on all Mitsubishi Electric related components starts. Any service or maintenance down the line goes through us. Because our team put the system in, we already know how it’s set up.

How a heat pump gets installed shapes how it performs for years afterward. That’s the work Bergeron Mechanical Systems has been doing across NH and VT for more than 50 years, now as a Diamond Elite Contractor.

The Comfort Zone Showroom

The Comfort Zone, our showroom in Keene, is the first fully interactive Mitsubishi Electric showroom in the state. Wall-mounted, floor-mounted, and multi-zone setups are all on display and running, so you can see the differences for yourself before deciding.

Family-Owned & Locally Operated

Bergeron Mechanical remains family-owned and run, with every install carried out by our in-house team. That approach has led to more than 500 five-star reviews from homeowners across NH and VT.

Is a Heat Pump Right for Your Hillsborough Home?

A few different scenarios lead homeowners to a heat pump. Some are ready to leave oil or propane behind. Some want to add cooling to a home built without it. Others have a heat pump that’s coming to the end of its useful life. In each case, what draws them in is having one system that covers both the winter and the summer.

The most common concern is whether it’ll keep up when it’s actually cold. Mitsubishi Electric’s H2i Plus is designed for cold-climate performance and rated to hold full heating capacity down to -5°F, so it holds through the coldest weather here.
