Apply Now for an ASHP Rebate
Who's Eligible for a CMLP Rebate?
Rebates are available to homeowners and renters for air-source heat pump installations in new or existing homes that meet the following eligibility requirements:
1. The installed air-source heat pump (ASHP) must be used for heating consistently throughout the winter.
2. The person installing your equipment must have received manufacturer training for that type of product. The manufacturer training need not have been provided by the manufacturer of the same brand of equipment that is being installed in your home, but it must be provided by a manufacturer of the same type of equipment (i.e. ductless training if ductless equipment is installed; ducted training if ducted equipment is installed.)
3. Equipment eligibility criteria: Install ductless single and multi-head systems and centrally ducted systems from the Northeast Energy Efficiency Partnership’s (NEEP’s) current ccASHP Specification List here.
4. You must have had a home energy audit within the last four years or have one scheduled within six months of project completion. New homes and multi-family residences with more than four units do not require an energy audit. CMLP recommends that priority recommendations from the audit are implemented before, or in coordination with, the installation of the ASHP. Natural gas users can contact MassSAVE at (866) 527-SAVE (7283) or www.masssave.com/en/saving/energy-assessments/ to sign up for an audit or get verification of a previous audit. All others can sign up with Energy New England at firstname.lastname@example.org, (888) 772-4242 or https://ee.ene.org/. CMLP can internally verify previous ENE audits, but not MassSave audits.
Rebate Type Eligibility:
If the project meets the above eligibility requirements, system owners should next determine which rebate type they are eligible for based on the following table:

*** Residences may install more than three single-head ductless systems, though the rebate will only support the first three installed. Rebates for central or multi-head systems are limited to 48,000 BTU/hr of heating capacity (maximum heating capacity at 5°F). Residences may install systems with greater capacity, though the rebate will only support the first 48,000 BTU/hr of heating capacity installed.
****For the purposes of determining rebate levels for central or multi-head systems, CMLP uses the system’s maximum heating capacity (BTU/hr) at 5°F.
Annual Rebate Caps
Applicants may install any combination of single-head ductless, multi-head ductless, and / or centrally ducted systems. For each 12 month period, each residence is eligible for a maximum rebate of $2,000 per project site address at the base rebate level, $3,000 with the 120% Income-Based Rebate, or $4,000 with the 80% Income-Based Rebate. Customers may apply for more than one ASHP rebate over the life of the ASHP rebate program. However, a customer may receive only one ASHP rebate within a twelve month period. This policy is subject to change in the future.
How Do I Apply for the ASHP Rebate?
There are 3 steps to apply for the ASHP rebate.
Step 1: Find an Installer
First select an ASHP installer, who can help you with your rebate application. CMLP recommends that residents:
- Review the material at “How can I learn about the best air-source heat pump options for my home?” and “What questions should I ask potential installers?” questions listed above.
- Solicit proposals from at least three installers.
- Check references from prior installations.
Prior to deciding to move forward with a system, residents who may meet income criteria should determine if they are eligible for the Income-Based Rebate, as described under the “Who’s Eligible for a Rebate?” question above. For example, a household of four with annual income of $132,230 or less may qualify. If eligible, complete one of the three income verification methods described in “How do I qualify for an Income Based Rebate?” question below.
Step 2: Select Eligible Equipment
Work with your installer to select eligible equipment: Install ductless single and multi-head systems and centrally ducted systems from the Northeast Energy Efficiency Partnership’s (NEEP’s) current ccASHP Specification List here.
Step 3: Apply for a Rebate
(Note: rebate applications must be received within 90 days of installation invoice date)
Once you select an installer and are ready to move forward with the project: Residents, with assistance from their installer, should complete and email the following documents to Energy New England, CMLP’s rebate processor, at email@example.com or postal mail to Concord Rebates c/o Energy New England, 5 Hampshire St., Suite 100, Mansfield, MA 02048.

- (Heat Load Calculation): For projects designed to supply 100% of the building’s heat with no supplemental heat source, a copy of the summary report for the Manual J (residential) heat load calculation, at the 99% dry bulb heating design temperature for the most relevant ACCA location. Heating set temperatures may be between 68 and 72 degrees Fahrenheit.
- (Installer's W-9 Form (IRS's Nov 2017 Revised Form)): Only required if customer directs CMLP to pay rebate to installer.
Rebate applications must be received within 90 days of installation invoice date. The Town of Concord assumes no liability for any equipment, installation or damages, and may inspect equipment to verify the above information at any time up to 1 year after receiving the rebate application.
In the interest of increasing access to air-source heat pumps for all residents of Concord, CMLP offers additional incentives for households with income below 80% or 120% of the state median income. Eligibility thresholds are determined based on household size. Eligibility for the income-based rebate is based on the income of the System Owner’s household.
Eligibility is based on total household income (Tax Return Form 1040, line 6), as determined by the system owner and household members’ federal income tax filings for the most recent year available. For rental properties, if the tenant is contracting directly with the installer for the installation of the project, the tenant would be the system owner. Each system owner is only eligible to receive the income-based rebate at one residence per 12 month period.
Income-Based Rebate Adder Thresholds by Household Size
80% of State Median Income
120% of State Median Income
To receive the Income-Based Rebate, the system owner must complete one of the following three income verification methods:
- Electric Bill: When submitting the application documents, provide CMLP with a copy of an electric bill from within the last six (6) months showing a Residential Assistance Credit.
- Fuel Assistance Letter: When submitting the application documents, provide CMLP with a copy of a fuel assistance letter of acceptance from the past twelve (12) months showing the date, system owner’s name, and project site address.
- Income Verification: Prior to submitting application documents, request income verification from CMLP by mailing the Income Verification Request form and the first two pages of the most recent federal IRS tax return form 1040 (showing line 6) for each adult filing (single, married filing jointly, married filing separately, and/or head of household) within the household to Attn: Pamela Cady at CMLP, P.O. Box 1029, Concord, MA 01742 or by hand delivery to CMLP’s Operations Center at 1175 Elm St, Concord. All tax information provided to CMLP will be shredded upon completion of income verification.
You will be notified by email or postal mail once your eligibility for an income-based rebate has been determined. Include this proof of income verification with your application documents.
How will I receive my rebate?
Rebates for ≥$600 are normally issued as checks from the Town of Concord. On the rebate application, customers may indicate whether they wish to have the check issued to their installer or to themselves. Customers may also choose to receive a bill credit instead of a check.
Commercial entities receiving checks ≥$600 will get a 1099 from Town for the relevant tax year, if required by tax code.
Does CMLP offer a special electric rate for heat pump users?
How do I qualify for an income-based ASHP rebate?
CMLP offers the R-7 “Electric Resistance & Heat Pump Heating Systems/DHW” rate for heat pump users, a special winter rate designed to prevent an unintended spike in electricity charges for electric heating customers as a result of CMLP’s tiered rate structure. This rate may benefit you if you already use more than 600 kilowatt-hours in some winter months, or if you expect to do so once your heat pump is installed.
However, In order to take advantage of this rate, you must request that a separate meter be installed by CMLP. This meter will record the electric usage of your heat pump. Electricity use recorded on this meter from October 1st through May 1st will be subtracted from the normal billing meter and billed at $0.14431 per kWh. From May 2nd through September 30th, the use through this meter will be billed under the regular R-1 Rate, which ranges from the tier 1 rate of $0.14431 to the tier 3 rate of $0.18685 per kWh, depending on how much electricity your household has used that month. CMLP’s R-1 rate schedule describes how your electric rate changes depending on how much electricity your household uses in a given month.
CMLP will supply and install the separate meter at no cost to you. However, you will need to pay an electrician to install a meter socket for the new meter. An additional electrical panel is typically needed as well. Costs for a meter socket/electrical panel can range from $1,000 to $4,000. The time it will take you to recoup the cost of the new meter socket/panel through electricity cost savings depends on several factors:
- the socket/panel installation cost;
- the extent to which your electric usage will exceed 600 kWh per month once your heat pump is installed and
- how long the tiered rate structure and the Electric Resistance & Heat Pump Heating Systems/DHW rate remain in effect. CMLP’s staff has made a recommendation to the Light Board that the tiered rate structure be eliminated. If the Board votes to do so, the Electric Resistance & Heat Pump Heating Systems/DHW rate will no longer be needed to prevent unintended spikes in electricity charges for heat pump users, and will also be eliminated. In that case, it is unlikely that you’d recoup your investment in a new meter socket and electrical panel through electricity cost savings.
Please note also that customers who have a solar array usually expect that solar electricity will lower the portion of their electric bill attributable to the electricity needed to power their heat pump during the winter. However, if a heat pump is separately metered so that a customer can receive the Electric Resistance & Heat Pump Heating Systems/DHW rate for winter usage, CMLP is unable to offset the winter usage measured by the separate meter with solar electricity generated by the array. Therefore, having a solar array will not lower a customer's winter bill for heat pump electricity usage if the Resistance & Heat Pump Heating Systems/DHW rate is in effect. During the summer, when the Resistance & Heat Pump Heating Systems/DHW rate does not apply, solar electricity will offset the portion of an electricity bill due to a heat pump being used for air conditioning, even if the heat pump is separately metered.
Further, heat pump customers with solar would need to locate the second meter next to the existing house meter in order for the solar electricity powering the heat pump to be accounted for properly. This can require longer wire runs that increase the cost of the meter socket installation.
Please consider these factors when deciding whether to invest in a separate meter/electric panel.
If you have further questions about the Electric Resistance & Heat Pump Heating Systems/DHW rate, please contact Carole Hilton, Customer Service Coordinator, at (978) 318-3158 or CHilton@concordma.gov.
