What rebates are available for Massachusetts homeowners?
Massachusetts homeowners may access rebates through Mass Save (for heat pumps, insulation, air sealing, and heat pump water heaters), federal 25C tax credits (for heat pumps and water heaters), and the SMART program (for solar). Rebate amounts depend on your utility, current heating fuel, home type, equipment model, and whether previous weatherization work has been completed. Use the calculator below to estimate your specific situation.

† ConnectedSolutions rates are annual demand response payments and vary by utility; subject to program changes. 25D battery credit: standalone batteries with ≥3 kWh may qualify since tax year 2023 (IRA). Heat pump (25C) and heat pump water heater share a combined $2,000/year credit cap if both installed in the same tax year. Consult a tax professional.
Common warning signs in contractor quotes
Most homeowners receive quotes with missing information, unverifiable savings claims, or rebate amounts that assume undisclosed eligibility. Here are the most common issues we see.
Full red flags guideQuote claims a rebate but lists no AHRI model numbers or eligible equipment documentation.
Installer shows "no-cost solar" or "pays for itself" without disclosing loan interest or dealer fees.
Savings claim does not specify fuel assumptions, utility rates, or system efficiency.
Battery bundled with solar but no clear backup, rate arbitrage, or demand response rationale given.
Payback period uses future utility inflation without disclosing that assumption.
Quote does not include warranty terms, labor coverage, or permit/electrical work details.
Homeowner questions about Massachusetts rebates
Do you need a Home Energy Assessment before getting Mass Save rebates?
For most insulation and weatherization rebates, yes. For heat pump rebates, it depends on the program path (whole-home vs partial-home). Check your specific upgrade category — the calculator will flag this requirement.
Can you stack Mass Save rebates with the federal tax credit?
Generally yes. The 25C federal tax credit and Mass Save rebates are separate programs. However, rebates that reduce your project cost may affect the base for calculating the credit. Consult a tax professional for your specific situation.
Does your current heating fuel affect your heat pump rebate?
Yes, significantly. Homes heating with oil, propane, or electric resistance often qualify for different rebate tiers than homes with natural gas. Fuel type is one of the most important eligibility factors in the Mass Save heat pump program.
How do you know if a contractor's savings claim is realistic?
A valid savings claim should specify current fuel cost, current system efficiency, projected heat pump efficiency (HSPF2), and your utility's electricity rate. Claims without these inputs cannot be verified and should be treated as estimates only.
