2026 Price Guide & Rebates
With energy costs rising and generous rebates available through Efficiency Maine, more homeowners across Midcoast Maine are installing high-efficiency heat pumps. But one of the most common questions we hear is:
How much does a heat pump actually cost to install in Maine?
The answer depends on several factors including the size of the home, the type of system installed, and the rebates available. In this guide, we’ll break down typical costs and how Maine homeowners can significantly reduce the price through incentives.
⸻
Average Heat Pump Cost in Maine
For most homes in Maine, the cost of installing a heat pump system typically ranges between:
$4,000 – $30,000 per system
Several factors influence the final price:
• the size of the space being heated
• the number of indoor units needed
• electrical upgrades
• the type of system installed
• installation complexity
In many homes, especially older New England homes, homeowners install one or two mini-split units first and expand later if needed.
⸻
Typical Heat Pump System Types
Ductless Mini-Split Systems
This is the most common type of heat pump installed in Maine.
Mini-splits consist of an outdoor condenser and one or more indoor wall-mounted units.
Typical cost:
$4,000 – $7,500 per unit installed
Mini-splits are ideal for:
• older homes without ductwork
• additions or renovations
• heating and cooling specific areas of the home
⸻
Whole-Home Heat Pump Systems (Ducted)
For larger homes or homeowners wanting a full heating solution, ducted heat pump systems may be installed.
Typical cost:
$12,000 – $35,000+ depending on system size
These systems can heat and cool the entire home through ductwork.
⸻
Efficiency Maine Rebates Can Reduce the Cost
One of the biggest advantages of installing a heat pump in Maine is access to Efficiency Maine rebates.
Rebates can significantly reduce installation costs.
Typical rebates include:
• Up to $3,000 per heat pump unit for many homeowners
• Higher rebates available for income-qualified households
• Additional incentives for whole-home systems
As of 2026, an additional $500 bonus rebate is also available for qualifying whole-home heat pump installations.
These incentives make heat pumps one of the most affordable heating upgrades available in Maine.
⸻
Energy Savings with Heat Pumps
Heat pumps are extremely efficient and can significantly reduce heating costs compared to oil, propane, or electric resistance heating.
Modern cold-climate heat pumps can operate efficiently even during Maine winters.
Benefits include:
• lower heating costs
• efficient cooling in summer
• improved comfort
• reduced carbon footprint
Many homeowners in Camden, Rockport, Rockland and throughout Midcoast Maine are switching to heat pumps for both heating and cooling.

Choosing the Right Heat Pump Installer
Because installation quality directly affects performance, choosing an experienced installer is important.
A qualified installer can:
• recommend the right system size
