What to Expect From Start to Finish

Free Design Consultation

A Design Consultant visits your Harrisville home to see how the house is actually built and hear what’s not working comfort-wise. We walk each room using LiDAR scanning technology and heat-loss calculation software to map the space and size the system to it. Free, no commitment.

Personalized Design

Once the walkthrough is done, we design a system specifically for your Harrisville home. Zoning, unit placement, and which Mitsubishi Electric configuration fits are all decided based on what we saw, not a standard package.

Precision Sizing

We use heat-loss calculation software to scan each space in your Harrisville home and get accurate measurements. Insulation, windows, exposure, and how each room is used all factor 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.

Ready for a Heat Pump That Respects Your Home?

Every Mitsubishi Electric system we install in Harrisville is designed on-site, not from a template. The Free Design Consultation is where that starts: a walkthrough, real measurements, and a plan built around your home.

FAQs

Heat Pump FAQs for Harrisville, NH Homeowners

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

Cost is a function of your home’s size and layout, plus the number of zones you need. Every Bergeron Mechanical Systems project starts with a Free Design Consultation, and you’ll receive a written proposal covering the full scope of the work before we begin.

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

Installation is bringing a Mitsubishi Electric heat pump into a home that doesn’t have one. Replacement is swapping out an aging system for a new Mitsubishi Electric one. Bergeron Mechanical Systems handles both, and both begin with the same Free Design Consultation.

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

Start with the Mitsubishi Electric Diamond Elite Contractor certification. It brings ongoing training directly from Mitsubishi Electric and is what separates specialists from general HVAC contractors. Bergeron Mechanical Systems holds this certification and has served New Hampshire and Vermont homeowners for 50+ years.

How long does a 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, though what system you choose matters. Standard heat pumps aren’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 determine how well it does.
