Bigger Rebate. Better Comfort. Smart Electric Choice.

Rebate Increase Announcement

Merrimac Municipal Light Department is proud to announce a major increase to our Air Source Heat Pump rebate. This enhanced incentive makes upgrading your home’s heating and cooling system more affordable than ever.

Rebate Increased from $250 to $2,500

Why Air Source Heat Pumps make sense in a Municipal Light Community

Choosing an air source heat pump is a smart investment—especially when you live in a community served by a municipal light department:

  • One system for heating and cooling
  • Provides central air conditioning for summer comfort
  • High-efficiency electric heating for winter
  • Powered by clean, locally managed municipal electricity
  • Improves comfort, efficiency, and home value year-round

Maximize Your Savings

  • MMLD Customers: Eligible for up to $2,500 in rebates
  • National Grid Customers: May be able to combine MMLD rebates with Mass Save® incentives

    By pairing these programs, homeowners can offset a large portion of the installation cost through available rebates and incentives.

      Now’s The Time to Upgrade

      Higher rebates, long-term energy savings, and year-round comfort make air source heat pumps one of the best home upgrades available today.

      Complete the rebate form for your new air source heat pump purchase. If you are a national grid customer, please contact HomeWorks Energy at 781-305-3319 who will complete the application for more savings through MassSave.
