What heat pump rebates pay in Worcester
We re-read MassCEC's heat pump page on October 3, 2026. Mass Save's own site blocks our checks, so its rebate table comes from a July 16, 2026 snapshot. Worcester is on National Grid's own list of the towns it serves, a Mass Save sponsor.
Whole-home heat pump
$2,650 per ton. The heat pump must be your main heat, and the home needs enough insulation.
Partial-home heat pump
Up to $8,500, for heat pumps that heat part of the home alongside your old system. Integrated controls are required.
Income-based Enhanced Rebates
Or no cost, for households that qualify by income. This is not the standard amount.
Alternative Energy Certificates
A one-time state payment. MassCEC's example is a 2,000 square foot home with a whole-home system.
Mass Save HEAT Loan
Terms up to 7 years, to spread the rest of the cost.
Federal tax credit (25C)
Ended for equipment placed in service after December 31, 2025.
Working it out
A 3-ton whole-home system: 3 x $2,650 = $7,950. A 4-ton system would be $10,600 by the math, but the cap is $8,500. The same 3 tons as a partial-home system: 3 x $1,125 = $3,375. MassCEC's cost example for a 2,000 square foot home is $22,000 before incentives and $12,500 after the $8,500 rebate and $1,000 in certificates.
Worcester's winters
Worcester's average January low is about -6.3°C (21°F), and the coldest reading in the last ten years was -27.2°C. Both are the coldest of the 13 Massachusetts cities we cover. Cold-climate heat pumps still heat at those temperatures, but they make less heat as it gets colder. Ask your installer for the unit's output at -15°C, and for a heat-loss calculation for your home.
If the heat pump can't carry the house on the coldest nights and your old system becomes the main heat, you get the partial-home rate. That is $1,125 per ton instead of $2,650.
How Worcester heats
The US Census Bureau's survey (2020 to 2024) says 51% of Worcester households heat with utility gas, 29% with electricity and 14% with fuel oil. Electric and oil homes, more than four in ten, are the ones that save the most.
What Worcester homes look like
Worcester has 85,876 homes, the most of any city on our list after Boston. About 43% of households own. Some 32% of homes are single-family detached and 34% are in two- to four-unit buildings. Three in four (75%) were built before 1980.
The rules that trip people up
Mass Save's heat pump rebates for 2026 have a few conditions that decide whether you get the big number or a small one. The system must be installed during 2026 by a contractor in Mass Save's Heat Pump Installer Network, and the equipment must be ENERGY STAR Cold Climate rated. Since January 1, 2026, heat pumps that use refrigerant with a global warming rating over 700, including the common R-410A, are off the qualified list. Ask your installer which refrigerant the model uses before you sign.
The whole-home rebate also asks that the home is insulated well enough, and you sign a form saying the heat pump will be your main heat. If you keep your old boiler or furnace running as the main heat, you are in the partial-home tier instead. Mass Save lists a $500 weatherization bonus and a $500 sizing bonus for partial-home systems. You apply after the install, and the deadline for 2026 installs is February 28, 2027.
