What’s New for the 2026 Mass Save® Heat Pump Rebates?

The 2026 Mass Save® rebate landscape has changed, and homeowners in Foxborough should move quickly to lock in higher incentive amounts before they decline further.

Rebates Have Dropped from 2025 Levels

In 2026, Mass Save lowered the overall rebate cap for air-source heat pumps by $1,500 compared to the previous year. This downward trend should be a signal for homeowners to take early action.

Here’s the updated breakdown of 2026 rebate categories:

• Whole-Home Installation: $2,650 per ton, up to $8,500  
• Partial-Home Upgrade: $1,125 per ton, up to $8,500  
• Basic Rebate Option: $250 per ton, capped at $2,500  
• Income-Based Enhanced Incentives: Up to $16,000 or more, often covering the entire system cost through Turnkey Services.

Each type depends on how much of your home’s heating load is covered by the heat pump solution and factors including household income and efficiency rating.

Efficiency and Refrigerant Compliance is Now Mandatory

To qualify for these rebates, your system must meet updated energy efficiency standards and utilize approved refrigerants. As of 2026, older systems that still use R-410A refrigerants no longer meet Mass Save eligibility criteria. Only heat pumps with low-global warming potential (GWP) refrigerants now qualify for rebates due to new climate mandates.

"If your current heating system relies on outdated refrigerants, 2026 is your last best chance to reap any major incentive before rebates decrease even further or phase out entirely."

Heat Pumps in Foxborough: Why They Make Sense

With changing climate patterns and the high cost of fossil fuel heating systems, heat pumps are ideal for year-round efficiency and comfort in towns like Foxborough.

Foxborough's Climate is a Natural Fit for Heat Pumps

Foxborough experiences cold winters and hot, muggy summers. A modern heat pump not only delivers efficient heating when it’s below freezing but also provides effective cooling during summer peaks.

Benefits for local homes include:

• Lower energy consumption during the heating season  
• High efficiency cooling comparable to central air  
• More precise zone-level temperature control  
• Quiet and space-saving designs suitable for New England architecture

Most Common Heating Types in Foxborough Are End-of-Life

Many Foxborough homes still use oil or gas-fired boilers, radiators, or electric baseboard heat. These systems are expensive to operate and don’t offer cooling. Swapping in heat pumps reduces total energy usage and futureproofs homes against utility price swings and future carbon regulations.

Updated Eligibility Rules You Need to Know in 2026

Mass Save’s 2026 rebate structure isn’t only about choosing the right system—it’s also about meeting specific criteria that determine your rebate level.

Whole-Home vs. Partial-Home Upgrades

• Whole-Home Rebate ($2,650 per ton): Requires that your heat pump meet 100% of your heating needs and that fossil fuel systems are removed or permanently disconnected.
• Partial-Home Rebate ($1,125 per ton): Ideal for blending heat pump usage with existing systems or for phased upgrades.
• Basic Option ($250 per ton): Simplified rebate for less comprehensive installations, suitable for supplemental or ductless room solutions.

Low-Income Households Gain Access to Turnkey Services

For eligible households in Foxborough, turnkey solutions under the income-based incentives offer up to $16,000—and in many cases, cover the entire cost. You must qualify for one of the income tiers as outlined by Mass Save's guidelines.

Important Changes in 2026: What Homeowners Should Watch

Understanding how the rebate environment in Massachusetts is evolving can help you act before benefits decline further.

Rebate Amounts Are Shrinking Every Year

Rebates have dropped from $10,000 in 2025 to $8,500 in 2026—and future reductions are expected. Unlike other incentives that grow with time, these are designed to phase out as heat pumps become standard.

Federal Tax Credits Have Ended

As of January 1, 2026, the federal heat pump tax credit—which once offered up to $2,000—has expired. That makes the Mass Save® rebate the main customization incentive currently available to residents in Foxborough.

Timing has never been more critical. Locking in the best rebate amounts while your system complies with efficiency and refrigerant regulations today can save substantial money—delaying means accepting lower incentives or missing out altogether.

"Waiting for better incentives could cost you. Rebates are decreasing, not increasing—and older systems won’t get grandfathered in."

Utility Discounts: Reduced Winter Electricity Rates

Foxborough homes connected to Eversource or National Grid can benefit from special utility programs that offer discounted electricity rates for usage during the heating season.

Winter Rate Programs Offer Ongoing Savings

• Available for households that shift primary heating to electric heat pumps  
• Designed to offset higher winter power usage typical with full-home heat pumps  
• Must apply separately from your Mass Save rebate

These reduced utility rates help further reduce your operational costs once your heat pump is installed—creating a much smaller annual heating bill compared to oil or propane heat.

Enroll Through Your Utility Provider

Check your eligibility with National Grid or Eversource based on your address in Foxborough. Not all homes are automatically eligible, and some rate reductions require proof of heat pump installation.

Why Acting Early Matters in Foxborough

The longer you wait, the more you lose—not just in terms of shrinking rebates but also in long-term energy savings.

Installation Windows May Fill Fast

As more homeowners seek to upgrade before rebates shrink again, installer backlogs typically grow. Booking a heat pump install in late summer or fall can mean missing the winter rebate window entirely.

Plan ahead and consider:

• Getting a load calculation for your home now  
• Reviewing refrigerant requirements for your chosen system  
• Securing documentation to qualify for whole-home or income-based incentives

Future Carbon Laws Will Affect All Homes

2026 is part of a larger carbon reduction plan unfolding across Massachusetts. Homes that do not switch to electrified systems could face new penalties, lack access to subsidies, or face higher utility rates over time.

By converting to an efficient, compliant heat pump in 2026, you align your home with the future of heating in Foxborough and take advantage of currently available support and infrastructure.

Final Notes for FOXBOROUGH Homeowners

If you're considering heating upgrades in Foxborough, MA, now is the time to explore the combination of incentives, energy savings, and long-term comfort that comes with installing a modern air-source heat pump. With Mass Save’s 2026 rebates reduced but still substantial—especially for whole-home systems and income-qualified households—delaying upgrades may lock you out of the best value.
