Our Heat Pump Installation Process

Free Design Consultation

A Design Consultant comes to your Amherst home to understand your comfort needs and see how the space is actually built. We walk through each room, and use LiDAR scanning technology and heat-loss calculation software to map the home and size the system to what it needs. The visit is free with no pressure to move forward after.

Personalized Design

After the walkthrough, we design a system built around your Amherst 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.

Precision Sizing

We use heat-loss calculation software to scan each space in your Amherst home and get accurate measurements. Insulation, windows, exposure, and how each room is actually used all feed into the calculation. What comes out is a system designed specifically for your home.

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.

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.

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.

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

Frequently Asked Questions About Heat Pumps in Amherst, NH

How much does heat pump installation cost in Amherst, NH?

Cost depends on your home’s size, layout, and the number of zones you need. That’s why every Bergeron Mechanical Systems project starts with a Free Design Consultation. You’ll get a written proposal covering the full scope of the work before anything begins.

What's the difference between heat pump installation and heat pump replacement?

Installation adds a Mitsubishi Electric heat pump to a home that doesn’t have one. Replacement swaps out an aging system for a new Mitsubishi Electric one. Bergeron Mechanical Systems handles both, and both start with the same Free Design Consultation.

How do I choose the right heat pump company in Amherst, NH?

Look for a Mitsubishi Electric Diamond Elite Contractor. The certification comes with ongoing training directly from Mitsubishi Electric and is what separates specialists from general HVAC contractors. Bergeron Mechanical Systems holds this certification and has served homeowners across New Hampshire and Vermont for over 50 years.

How long does heat pump installation take?

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.

Do heat pumps actually work in cold New Hampshire winters?

Yes, but the system matters. A standard heat pump isn’t built for New England winters, which is where the misconception comes from. A Mitsubishi Electric cold-climate heat pump is engineered to keep operating through winter temperatures, and correct design and installation are what make sure it performs the way it’s built to.
