💸 What Impacts HVAC System Costs?

When you use our online quote tool, you’ll see a variety of pricing options based on your answers. Several factors impact the final cost of a new HVAC system:

1. System Type

Central air conditioning
Gas furnace and AC combo
Ducted heat pump
Ductless mini splits
High-velocity systems like Unico

Each type comes with different equipment, labor, and rebate eligibility.

2. Home Size & Layout

Larger homes or multi-zone systems require more capacity—and more equipment.

3. Ductwork Condition

Existing ductwork in poor condition may need sealing, repairs, or replacement.

4. Electrical Panel Compatibility

Installing a heat pump may require an electrical panel upgrade to support new loads.

5. Energy Efficiency & Rebates

Higher-efficiency systems cost more up front but may qualify for Mass Save® rebates, federal tax credits, and utility incentives.

🌡️ Why More Homeowners Are Choosing Heat Pumps

If you're considering a new HVAC system, now is a great time to switch to an electric heat pump system.

These all-in-one systems heat and cool your home efficiently, with lower carbon emissions and huge potential rebates.

As a Mass Save Heat Pump Installer Network (HPIN) contractor, Denommee helps customers qualify for:

Up to $10,000 in Mass Save rebates
0% HEAT Loans up to $50,000
Up to $2,000 in federal tax credits

We’re also approved by Abode Energy for Municipal Light Plant (MLP) heat pump incentives in towns like Concord, Groton, and Littleton.
