How We Install Your Heat Pump

1

Free Design Consultation

A Design Consultant meets you at your Hanover home to understand what the system needs to do. Room by room, we use LiDAR scanning technology and heat-loss calculation software to map the space and size the system correctly. The visit is free with no pressure after.
2

Personalized Design

Design starts once we’ve seen the house. For your Hanover home, that means deciding which rooms get their own zone, where units go, and which Mitsubishi Electric configuration matches your layout best.
3

Precision Sizing

Heat-loss calculation software scans each space in your Hanover home for accurate measurements. Insulation, windows, exposure, and how each room is actually used all feed into the calculation. The result is a system designed specifically for your home.
4

Transparent, No Hidden Cost, Proposal

You get a written proposal during your design appointment, covering the full scope of the work: equipment, electrical, labor, and warranty coverage. No hidden costs. If anything comes up at your pre-installation appointment that would change the plan, our installation manager works through the solution with you before any work begins.
5

Precision Installation

We handle the full permitting process with your local code officer, then meet or exceed Mitsubishi Electric’s specifications on every install, from the bluestone pad and corrosion-resistant aluminum stand to the electrical connections and where each component is placed. All electrical work stays in-house with our on-staff Master Electrician. Being a Diamond Elite Contractor means the crew on your job has trained specifically on this equipment.
6

Final Testing & Optimization

Once installation wraps, we commission the system: running it end to end, checking each zone for heating and cooling, verifying airflow across the units, and confirming every control responds. Before the crew leaves, we teach you how to operate your new system.
7

Ongoing Support & Maintenance

Every installation is backed by 1-year bumper-to-bumper coverage on all parts and labor. From there, we register your 12-year warranty on all Mitsubishi Electric components and mail you the certificates. Our Service team has been doing this for over 50 years, so you can count on us for the life of your system.

FAQs

Common Questions About Heat Pumps in Hanover, NH

The number of zones, plus your home’s size and layout, all shape the cost. That’s why every Bergeron Mechanical Systems project starts with a Free Design Consultation. You’ll get a written proposal with the full scope of the work in writing before anything moves forward.
Installation adds a Mitsubishi Electric heat pump to a home without one. Replacement takes out an old system and puts in a new Mitsubishi Electric one. Both are handled by Bergeron Mechanical Systems, and both start with a Free Design Consultation.
Look for a Mitsubishi Electric Diamond Elite Contractor. That certification carries ongoing training directly from Mitsubishi Electric and marks a specialist from a general HVAC contractor.

A typical heat pump installation takes 1-day but could be 2-3 days. The duration depends on the number of zones and complexity of the installation. Our Installation Manager will clearly communicate what to expect and will confirm all dates with you.
Yes, but the system has to match the climate. Standard heat pumps aren’t designed for New England winters, and that’s where the misconception starts. A Mitsubishi Electric cold-climate heat pump is engineered to keep operating through winter, and correct design and installation are what determine performance.
