Thinking about a heat pump for your Medford home but not sure if the rebates, rates, and real savings add up? You are not alone. Incentives and utility pricing changed in 2025, which makes the math feel complicated. In this guide, you will see what you can get from Mass Save, how the new winter discount rate works, and how to estimate true costs and payback in Medford. Let’s dive in.
Why heat pumps in Medford now
Two things make 2025 a strong year to consider a heat pump in Medford. First, Mass Save offers significant upfront rebates and 0% HEAT Loans that can lower your initial cost. Second, the state approved a new seasonal delivery rate for heat pumps that can trim winter bills by an average of about $540 for eligible customers starting November 1, 2025. Together, these benefits can shorten payback for many homes.
Massachusetts electricity prices are relatively high, around 30 cents per kWh this year. That means the fuel you replace matters. Households switching from oil or propane often see the biggest savings. If you heat with natural gas, you need a custom estimate to see the impact.
Mass Save rebates and loans
Mass Save remains the primary path for rebates in Massachusetts. For 2025 installs:
- Whole-home air-source heat pump: $3,000 per ton, capped at $10,000.
- Partial-home air-source heat pump: $1,250 per ton.
- Income-qualified customers may access enhanced incentives that are even larger.
You must use a contractor in the Heat Pump Installer Network and complete required verification. You can also use a 0% Mass Save HEAT Loan to finance eligible work. See current rules and qualified installers on the Mass Save heat pump page. Visit the program page for details on rebates and the HEAT Loan at the Mass Save air-source heat pump hub and the enhanced incentives overview.
Federal credits for 2025 projects
Federal rules changed in 2025. The law known as P.L. 119-21 limits key residential credits so that expenditures placed in service after December 31, 2025 are generally not eligible. If you plan to claim a federal heat pump credit for 2025, confirm timing and eligibility for your specific project with a tax professional. You can review the statutory text on Congress.gov.
New winter discount rate for heat pumps
Starting November 1, 2025, eligible customers of Eversource, National Grid, and Unitil can enroll in a seasonal delivery discount that applies from November through April. The Massachusetts DPU estimates average winter savings of about $540 per household. Some homes that installed through Mass Save since 2022 may be auto-enrolled, but you should confirm with your utility before winter. Read the state’s announcement for details on the heat pump discount rate.
Remember, your electric bill has two parts: supply and delivery. The new discount affects the delivery portion only.
Medford CEA and your rate
Medford runs a Community Electricity Aggregation program that sets supply options for residents. The program has historically secured lower supply rates and offers renewable choices. Supply works alongside the delivery discount to determine your total bill. Learn more from the city’s update on Medford Community Electricity Aggregation.
What it could cost here
Installed costs vary by home and system type. Ductless mini-splits can run from several thousand dollars for a single zone to higher for multi-zone setups. A full ducted system often falls in the $12,000 to $24,000 range depending on ductwork, electrical upgrades, and home size. For planning context, see statewide guidance from MassCEC’s Go Clean resource.
Sample net cost math
Here is a simplified example for a 2,000 square foot Medford home replacing oil with a 3-ton whole-home air-source heat pump:
- Example installed cost: $12,000.
- Mass Save whole-home rebate: 3 tons × $3,000 per ton = $9,000.
- Net after Mass Save: $3,000.
- If eligible in 2025, a federal credit may further reduce cost. Confirm with your tax advisor based on the new law.
Actual costs and incentives depend on your quotes, equipment, and timing. Always verify eligibility and paperwork with your installer.
Will it save you money
Savings depend on your current fuel and system design:
- If you switch from fuel oil or propane, you may save several hundred dollars per year, sometimes more. National research shows average savings around $370 per year, with larger savings for oil or propane users. See the overview from Rewiring America.
- If you heat with natural gas, savings may be smaller. Because Massachusetts electricity prices are about 30 cents per kWh, your results hinge on system efficiency and the new winter delivery discount. Check current price data at the U.S. Energy Information Administration.
How to maximize rebates and savings
Follow these steps to stack your benefits and avoid delays:
- Schedule a free Mass Save Home Energy Assessment if you are eligible. Weatherization upgrades often improve heat pump performance and can unlock higher incentives. Start at the Mass Save heat pump page.
- Contact the city’s Electrify Medford program for a free energy coach and help with applications. Get support at Electrify Medford.
- Get at least two quotes from Mass Save Heat Pump Installer Network contractors. Confirm equipment eligibility and that your installer will submit the rebate paperwork.
- Ask your installer to model your annual operating costs using your past bills. Make sure they include the November through April delivery discount. Confirm whether you need to enroll with Eversource or National Grid before winter.
- If you plan to claim a federal credit for 2025, confirm timing and eligibility with a tax advisor and review the updated law on Congress.gov.
- Review your electricity supply choice. Compare Medford CEA options with any other supplier offers, since supply price plus delivery discount determines your final bill. See the city update on Medford CEA. You can also search programs statewide with the Massachusetts Energy Savings Finder.
For sellers and buyers
Energy upgrades can make a home more comfortable and easier to own. A well-designed heat pump, paired with good insulation and air sealing, can reduce monthly operating costs and add appeal to value-minded buyers. If you are preparing to sell or comparing homes to buy, it helps to understand the system type, capacity, and expected utility costs for the property.
