*Buildings primarily heated with natural gas are not eligible for CMLP’s heat pump rebates, but may apply for similar rebates through Mass Save.
**Tons are calculated based on AHRI cooling capacity divided by 12,000 BTU/hr.
***Heat pumps that use a hydronic or water loop internal to the building (i.e. not a ground loop) as a heat source/sink are not eligible for CMLP rebates at this time.
Rebate Cap:
- Rebate not to exceed project cost, which is documented by invoices and/or receipts. In-house labor does not count towards the cost of the project.
- A customer is eligible for a maximum of $50,000 in heat pump rebates every 3 years. A "customer" is defined by a unique customer number in CMLP's billing system. In most cases, a customer with multiple accounts will have the same customer number assigned to them. However, if a business or property owner or manager has multiple customer numbers in CMLP's billing system, CMLP can, at its sole discretion, define them as a single customer.
- If the property is sold, the new account holder’s cap resets at $50,000 every three years, regardless of rebates awarded to previous account holders.
Rebate cannot be combined with a National Grid/Mass Save rebate for the same equipment.
Rebate Eligibility for Multi-Unit Properties
In addition to being available for businesses of all types, CMLP's commercial heat pump rebates are available for the following types of multi-unit properties:
- Residential condominium association-owned buildings used partially or fully for non-residential purposes (e.g. management office, clubhouse, fitness center)
- Apartment buildings with 4 or more units
- Transient or non-transient group quarters (includes nursing homes, care & treatment facilities, residence halls & dorms)
- Multi-tenant non-residential commercial buildings
The way in which CMLP applies its heat pump rebate policies to different types of multi-unit properties is based upon:
- Property type classification codes known as “Use Codes,” that are displayed in the “Land Use” section of each property record in the Concord Assessor’s database.
- Electric service addresses in CMLP’s billing system.
