Our Heat Pump Installation Process

1

Free Design Consultation

A Design Consultant meets you at your Lebanon home to understand your comfort needs and see the space firsthand. We use LiDAR scanning technology and heat-loss calculation software to map each room and size the system to what it needs. No cost, no commitment.
2

Personalized Design

After we’ve seen the house, we design a system around your Lebanon home. That includes which rooms should have their own zone, where units are placed, and which Mitsubishi Electric configuration fits your layout best.
3

Precision Sizing

Heat-loss calculation software scans each space in your Lebanon home for accurate measurements. Insulation, windows, exposure, and how each room is used all factor 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 componentes 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 Lebanon, NH

The size of your home, its layout, and the number of zones needed all factor into the final cost. 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.
Installation puts a Mitsubishi Electric heat pump in a home that doesn’t have one yet. Replacement takes out an old system and puts a new Mitsubishi Electric one in its place. We handle both, and both begin with the same Free Design Consultation.
A Mitsubishi Electric Diamond Elite Contractor is the certification that matters. It brings ongoing training directly from Mitsubishi Electric and distinguishes specialists from general HVAC contractors. Bergeron Mechanical Systems holds this certification and has served New Hampshire and Vermont homeowners for over 50 years.
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 it comes down to the system. A standard heat pump isn’t built for New England winters, which is where the misconception starts. 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.
