A photo of the serial number from your heat pump outdoor condenser is required to receive the Mass Save rebate.
- Locate your outdoor condenser. It might look like a box on stilts (or legs), a box resting on the ground, or a box fixed to a stand on the side of your house. No matter what it looks like, there will be a fan inside.


- Identify the equipment label. (also referred to as ‘nameplate’). This is located on the outside of the condenser, see pictures below for examples.


- Take a photo. Make sure your photo is clear and the serial number is legible.

- Upload the photo with your rebate submission through the Online Rebate Portal. For mail-in applications, please print and include a copy of the photo.
Photos of indoor equipment are not required.
If you are struggling to find your equipment label and/or serial number, contact your heat pump installer for assistance.
