Massachusetts Heat Pump Rebates
Get up to $16,000 in rebates for heat pump installations through Mass Save. Air source, ground source, and mini-split systems all qualify.
Quick Summary
What is a Heat Pump?
A heat pump is an all-in-one heating and cooling system that moves heat rather than generating it. In winter, it extracts heat from outdoor air (even when cold) and moves it inside. In summer, it works like an air conditioner, removing heat from your home.
Air Source Heat Pump (Ducted)
Uses existing ductwork to heat and cool your entire home. Best for homes with existing forced-air systems.
Ductless Mini-Split
Individual units mounted on walls, no ductwork required. Ideal for room-by-room control or homes without ducts.
Ground Source (Geothermal)
Uses underground loops for exceptional efficiency. Higher upfront cost but lowest operating costs.

The Federal Credit No Longer Stacks
The federal 25C tax credit that used to stack on top of Mass Save rebates was repealed effective December 31, 2025 and does not apply to work done in 2026. Mass Save is now the incentive that matters in Massachusetts. The New England Heat Pump Accelerator now takes $650 off each outdoor unit at the point of sale.
Example: $15,000 Heat Pump Installation in 2026
Mass Save pays $2,650 per ton, up to $8,500 — this example assumes a system large enough to reach the cap. Income-qualified households can receive up to $16,000. The federal 25C credit was repealed effective December 31, 2025; through 2025 this same project came to $3,500.
Frequently Asked Questions
Do heat pumps work in Massachusetts winters?
Yes! Modern cold-climate heat pumps are designed to work efficiently in temperatures well below freezing. Many models operate down to -15°F or lower. Mass Save only provides rebates for heat pumps that meet cold-climate efficiency standards.
Can I keep my existing heating system as backup?
Yes, you can install a heat pump alongside your existing furnace or boiler. This "hybrid" approach lets the heat pump handle most heating needs while the backup system kicks in during extreme cold. You'll still qualify for rebates.
How long does installation take?
A typical ducted heat pump installation takes 1-2 days. Ductless mini-splits can often be installed in a single day. Ground source systems take longer (1-2 weeks) due to the underground loop installation.
How long does it take to receive my rebate?
After submitting your final documentation, rebate checks typically arrive within 6-8 weeks. Some contractors offer instant rebates where the discount is applied directly to your invoice.
