Concord Heat Pump Rebates for 2026: What Homeowners Need to Know

All information updated based on published data as of January 4, 2026 

Are you a homeowner in Concord, Massachusetts, considering switching to heat pumps? Whether you’re interested in an air source heat pump, a ground source heat system, or a hybrid heating cooling setup, the potential savings go far beyond lower utility bills, they also include generous CMLP heat pump rebates that put cash back in your pocket. By planning your heat pump project with the right rebate application strategy, you can maximize both efficiency and savings.

The Concord Municipal Light Plant (CMLP) Heat Pump Rebate Program is here to help you save on energy-efficient heating solutions while supporting Concord Light’s community-wide sustainability goals. CMLP, often referred to as Concord Light or “Light Plant CMLP,” regularly updates its rebate amounts, equipment eligibility criteria, and pre approval requirements, so staying on top of program changes is essential.

As a contractor who has frequently worked with CMLP customers, Endless Energy ensures you stay informed about the latest heat pump rebates and incentives for 2026. We guide you through every step, from pre-approval to final department electrical inspection, so you can feel confident about receiving your rebate without delays.

CMLP Heat Pump Rebates 2026 Overview

CMLP’s heat pump rebates are designed to help even more residents transition from electric resistance heat and fossil fuels to efficient source heat pumps:

✅ Whole Home Heat Pump Rebate: $3,000 per ton (capped at $10,000)

✔ Equipment must be listed on the Mass Save Heat Pump Qualified Product List, meeting strict equipment eligibility standards set by the Concord Building Department and CMLP.

✅ Partial Home Heat Pump Rebate: $1,250 per ton (capped at $10,000)

✔ Requires integrated controls if the supplemental heating system uses oil or propane, ensuring that your new source heat pump operates as the primary heating solution for the majority of the season.

If your home uses supplemental electric heat (electric baseboards, existing heat pumps, ETS, or other electric resistance systems) outside of bathrooms, you can only qualify for the whole home rebate if supplemental electric heating accounts for 10% or less of your total heating load. Meeting this eligibility criteria is vital for rebate approval.

Condominium units and other multi-unit properties (5+ living units) are now eligible for whole home rebates if they meet all criteria, making it easier for condo associations and landlords to launch larger heat pump projects that benefit multiple families and tenants.

Eligibility & Key Requirements

To qualify for CMLP’s Whole Home Heat Pump Rebate, your system must meet specific criteria:

✅ Proper Sizing: Heat pumps must fully heat your home (per Town of Concord’s property assessment database) and be sized to cover 90–120% of your total heating load at 8°F outdoor design temperature (ASHRAE 2021). A Manual J heat load calculation is required, and our team provides this calculation as part of the heat pump installation process.

✅ Oversized Systems: If your system exceeds 120% of the heating load, rebates may still be approved at CMLP’s discretion, provided equipment eligibility is confirmed and documented during the pre-approval phase.

✅ To maximize your rebate savings, submit the Optional Pre-Approval Form before signing an installation contract. This pre approval step allows CMLP to confirm equipment eligibility, verify rebate amounts equipment categories, and schedule any necessary building department electrical inspections.

Remember, CMLP offers final inspection approval in coordination with the Concord Building Department, ensuring your heat pump installed meets all safety, sheet metal ducting, and department electrical inspection standards. Passing the electrical inspection approval quickly accelerates the timeline for receiving rebate funds.

Supplemental Heat Rules:

If using supplemental electric heat (outside bathrooms), the total must not exceed 10% of your home’s total heat load. Adhering to this limitation maximizes rebate eligibility and keeps your operating costs lower.

Emergency heating options:

Homes may maintain backup heating from:

  • Electric resistance strips in the heat pump for occasional use
  • Wood/pellet stoves, boilers, or furnaces to handle extreme cold snaps
  • Fossil fuel (oil or propane) boilers/furnaces when required

Frequently Asked Questions About Concord Heat Pump Rebates (2026)

How much are Concord heat pump rebates in 2026?

For 2026, Concord Municipal Light Plant (CMLP) offers two primary rebate options:

Final rebate amounts depend on system type, sizing, and eligibility approval.

What qualifies as a “whole-home” heat pump in Concord?

A system qualifies as whole-home if it:

  • Is sized to cover 90–120% of your home’s heating load at an 8°F outdoor design temperature

  • Uses a Manual J heat load calculation

  • Serves as the primary heating source for most of the winter

If supplemental electric heat is used, it must account for 10% or less of total heating load (excluding bathrooms).

Do I need to remove my oil or propane system to qualify?

No. Many homes keep oil or propane systems as backup heat for extreme cold. To qualify for the whole-home rebate:

  • The heat pump must handle the majority of heating hours

  • Integrated controls may be required to prevent the fossil fuel system from running unnecessarily

This setup is common in Concord homes transitioning gradually to electrification.

What happens if my heat pump system is oversized?

If your system exceeds 120% of the calculated heating load, CMLP may still approve the rebate at its discretion, provided:

  • The equipment is on the approved eligibility list

  • Oversizing is clearly documented during the pre-approval process

This is why pre-approval is strongly recommended before signing a contract.

Is CMLP pre-approval required before installation?

Pre-approval is technically optional, but skipping it is risky. Submitting the Optional Pre-Approval Form before installation allows CMLP to:

  • Confirm equipment eligibility

  • Verify rebate amounts

  • Flag electrical or inspection requirements early

Homes that skip pre-approval are more likely to experience rebate delays or denials.

Are condos and multi-unit properties eligible for rebates?

Yes. Condominium units and multi-unit buildings with five or more units may now qualify for whole-home rebates, as long as all eligibility criteria are met. This has made larger heat pump projects far more feasible for Concord condo associations and landlords.

Will my heat pump need an electrical inspection?

Yes. All rebate-eligible installations require final inspection approval coordinated between CMLP and the Concord Building Department. This ensures:

  • Electrical service capacity is adequate

  • Wiring and equipment meet safety standards

  • The system complies with rebate program rules

Passing inspection is required before rebate funds are released.

How long does it take to receive the rebate?

Once installation and inspections are complete, rebate processing typically takes several weeks, depending on application completeness and inspection scheduling. Projects with pre-approval and proper documentation move significantly faster.

Can Endless Energy handle the rebate process for me?

Yes. Endless Energy manages the entire process, including:

  • Manual J calculations

  • Equipment eligibility confirmation

  • Pre-approval paperwork

  • Coordination with Concord Light and inspectors

  • Final rebate submission
