Hybrid heat pump installation by Endless Energy in Braintree Massachusetts

If you’re planning to install a heat pump in Massachusetts this year, you’re in luck—Mass Save rebates in 2025 can still reach up to $16,000. But not all systems or contractors qualify. To unlock these savings, your installation must meet strict Mass Save Heat Pump Standards, and the contractor must follow a detailed installation checklist.

Here’s what that really means—and why it matters for your home.

⚠️ Not All Heat Pumps (or Contractors) Qualify in 2025

Mass Save’s 2025 guidelines require:

  • High-efficiency equipment that meets or exceeds specific SEER2 and HSPF2 ratings

  • Whole-home design principles (Manual J) for $10,000 whole home rebate ($16,000 for enhanced whole home rebate based on income and fuel source)

  • Integrated Controls with proper set points (30 degree switchover for natural gas and 5 degrees for propane customers) for homeowners looking to keep their existing fossil fuel system

  • Installation by a contractor who’s part of the Mass Save Heat Pump Installer Network (HPIN)

  • Full compliance with the Mass Save 2025 Installation Checklist

Missing any of these? You could miss out on thousands in rebates—and end up with a system that doesn’t meet code or perform properly.

🔍 2025 Mass Save Heat Pump Requirements

✅ Equipment Efficiency Standards

To qualify for rebates:

✅ Whole-Home Design Standards

For whole-home rebate eligibility:

  • Must replace 90–120% of the home’s heating load

  • Requires a Manual J load calculation

  • System must cover all conditioned living spaces

  • Proper duct design or room-by-room zoning is required (this generally requires a Manual D)

🧰 2025 Mass Save Installation Checklist

Every rebate-eligible install in 2025 must follow this Mass Save’s quality checklist. Key parts of the checklist include:

✅ Manual J Load Calculation Completed
✅ Proper Sizing via Manual S
✅ Thermostats Properly Installed and Programmed
✅ Filters & Drain Lines Installed to Code
✅ Installed 12″ above the ground
✅ Refrigerant Lines Insulated & Tested for Leaks
✅ Proper Electrical & Plumbing Connections
✅ System Start-Up with Customer

Many heat pump installations are randomly inspected by Mass Save and if any box is missed, Mass Save has the right to reject the rebate. Especially if you are working with a contractor who is not taking your rebate upfront (Endless Energy does!), you could be on the hook for that amount! Nobody wants to end up paying more than they planned to!

💸 Real-World Savings in 2025

By complying with the updated standards:

  • Most homes still qualify for up to $16,000 in Mass Save heat pump rebates

  • Heat pumps can replace your fossil fuel system entirely (we only install cold climate heat pumps, many of which operate down to -22 degrees outside…and we really DON’T see that in New England).

  • You gain year-round comfort and a significantly more efficient home

  • You protect your system investment with warrantied, code-compliant work

✅ Bottom Line: Don’t Leave Money (or Comfort) on the Table

Mass Save heat pump rebates in 2025 are generous—but only if your system and contractor meet the requirements. Endless Energy makes sure they do – and we take Mass Save heat pump rebates upfront so you don’t have to wait and you don’t have to worry.
