Mass Save rebate checklist before you hire a contractor

Before you buy equipment or sign a home improvement quote, slow down and verify the rebate path. A few questions up front can prevent missed paperwork, ineligible equipment, or work done in the wrong order.

Before you sign

• Which exact rebate or financing program are we relying on?
• Does my ZIP code, utility, heating fuel, income status, or home type affect eligibility?
• Is a home energy assessment required before installation?
• Does the product model meet current efficiency requirements?
• Does the contractor participate in the required installer network?
• Who submits the application, and what documents will I receive?
• What happens if the rebate is denied or program funding changes?

Documents to collect before applying

Before work starts, create a simple folder for the project. Rebate applications are easier to review when the quote, invoice, model details, and program paperwork all match.

• Utility account information and the project property address.
• Before-work photos if the program or contractor requests them.
• Signed quote or proposal with scope, model numbers, and rebate assumptions.
• Final paid invoice showing installed equipment or weatherization work.
• Qualified product list confirmation, AHRI certificate, or efficiency documentation when applicable.
• Home energy assessment, weatherization, integrated control, or verification forms if required.
• Contractor license, installer-network status, and who is responsible for submitting the rebate.
