Applicable Building Stock
CMLP’s heat pump rebates are available for heat pumps installed in existing buildings, and/or newly constructed additions to existing buildings. They are not applicable to heat pumps installed in newly constructed homes or newly constructed outbuildings.
Equipment must be used to supplement or replace oil, propane, electric baseboard (resistance) or pre-existing heat pumps as the primary heating system. Households whose primary heating fuel is natural gas are not eligible for CMLP’s heat pump rebates, but may apply for similar rebates through Mass Save.
Home Energy Assessment Requirement
If a home was built before 2008, a no-cost home energy assessment within the last three years or scheduled within six months after project completion is required. Outbuildings listed in the “Outbuildings” section of the property record in the Town of Concord’s online assessment database are exempt from the home energy assessment requirement.
Completed Home Energy Assessment: If you believe you had an assessment in the last three years through CMLP, but do not know the date, contact Energy New England, CMLP’s assessment provider, at 1-888-772-4242 or firstname.lastname@example.org for assistance.
Scheduling a No-Cost Home Energy Assessment: Visit our Home Energy Assessments webpage for instructions on scheduling an assessment.
CMLP strongly recommends that priority weatherization recommendations from the home energy assessment be implemented before, or in coordination with, the installation of the heat pump. A tight, well-insulated home optimizes heat pump performance, and may allow for a smaller heat pump to be installed, saving you money upfront and on your monthly utility bills. CMLP’s weatherization rebates help you increase your home’s efficiency and prepare for a new heating system.
Project Pre-Approval and Quality Assurance Requirements
Pre-Approval: To ensure optimal performance, comfort, and cost savings, heat pump projects must receive sizing and design pre-approval by Abode Energy Management before installation begins, and pass a quality assurance check by Abode after installation is complete, in order to qualify for a rebate. Click for sizing and design pre-approval forms for air-source or ground source heat pump projects. Installers must submit the pre-approval form to Abode prior to installation.
Quality Assurance: Abode will review the proposal and provide pre-approval or feedback. Installers must submit a post-installation quality assurance form to Abode once installation is complete. Click for quality assurance forms for air-source or ground-source heat pump projects. The quality assurance check may include an on-site inspection, if necessary.
Town Building Department Permit and Inspection Requirements
The project electrician must apply for a Town electrical permit before work begins and schedule an electrical inspection after the work is done. CMLP will not award rebates until projects have passed an electrical inspection by Concord's Building Department.
If the project requires sheet metal ducting work that goes beyond minor repairs, a sheet metal permit must be obtained for the project. Examples of projects that require a sheet metal permit include installation of new ducting or replacement, significant repairs or changes to existing ducting. The Town of Concord's inspector must have inspected and approved the sheet metal work.
CMLP will verify that the project has passed the necessary inspections. Find out more details about permits and inspections in the Quality Assurance section on this page. The Building Department's contact information and hours are here.
Do-It-Yourself Heat Pump Installations
Do-it-yourself (DIY) heat pump installations are eligible for rebates under the following conditions:
-- A licensed electrician obtains an electrical permit and does the wiring. The installation must pass a Concord Building Department electrical inspection.
-- If the project involves sheet metal work beyond minor repairs, a tradesperson qualified to obtain a sheet metal permit must do so. The sheet metal work must pass a Concord Building Department inspection.
-- When applicable, refrigerant lines must be charged, sealed, and tested by a licensed professional to adhere to EPA regulations (some self-install systems are pre-charged and pre-sealed). If an existing HVAC system is being decommissioned, existing refrigerant must be properly recaptured.
-- The rebate cannot exceed the cost of the project, which is documented by invoices and/or receipts. Therefore DIY labor does not count towards the cost of the project.
