What to Expect From Start to Finish

1

Free Design Consultation

Since our home base is in Keene, a Design Consultant can be at your home to walk through your comfort needs. Using LiDAR scanning technology and heat-loss calculation software, we map each room and size the system to what the home actually needs. Free visit, no pressure after.
2

Personalized Design

With the walkthrough done, we design a system around your Keene home. Zoning, unit placement, and which Mitsubishi Electric configuration fits your layout are all decided based on what we found during the visit.
3

Precision Sizing

We use heat-loss calculation software to scan each space in your Keene 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.
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

Heat Pump FAQs for Keene, NH Homeowners

Cost depends on your home’s size, layout, and how many zones you need. Every Bergeron Mechanical Systems project starts with a Free Design Consultation. A written proposal covering the full scope of the work is delivered before any installation begins.
Installation adds a Mitsubishi Electric heat pump where one doesn’t yet exist. Replacement swaps out an aging system for a new Mitsubishi Electric one. Bergeron Mechanical Systems handles both, starting each with a Free Design Consultation.
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 New Hampshire and Vermont homeowners for over 50 years from its Keene home base.
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, though the system has to match the climate. Standard heat pumps aren’t built for New England winters, and that’s where the misconception comes from. A Mitsubishi Electric cold-climate heat pump is engineered to keep operating through winter, and correct design and installation are what determine performance.
