Energy Efficiency & Electrification

The Town of Lexington is committed to helping residents and businesses reduce their carbon footprint and save money on their energy bills. By increasing the energy efficiency on your home or business you can reduce your energy use. Switching to electric heating and cooling systems is one of the most impactful way residents can reduce the town's contribution to climate change.

HomeWorks Energy

HWE-Logo-FullLexington has partnered with HomeWorks Energy to provide its residents with a wide array of actions households can take to reduce their carbon emissions and build a resilient community. Start with a Mass Save® Home Energy Assessment to learn how your home consumes and loses energy.

Mass Save

Mass Save® offers free home energy assessments. Homeowners and renters are eligible to participate every three years. Benefits include:

  • mass-save-logo-dInstallation of no-cost energy-saving products, such as advance power strips, low-flow showerheads, and programmable thermostats
  • Eligibility screening for Mass Save rebates and incentives
  • Infrared testing, which measures surface temperatures using advance cameras to see if you need additional insulation
  • Combustion safety testing of your natural gas, oil or propane appliances to screen for carbon monoxide, drafts, and spillage

You can also choose to work directly through a Mass Save® Participating Home Performance Contractor.

Heat Pumps

Heat pumps are a flexible, cost-effective and energy-efficient option for both heating and cooling your home. They are heating and cooling systems that move heat indoors in the winter and draw heat outdoors in the summer. Instead of burning fossil fuels, they’re powered by electricity to move—rather than create—heat to keep your home or business at a comfortable temperature year-round. Today’s cold climate heat pumps can be up to 400% efficient and many provide efficient heating at outdoor temperatures as low as -15 °F. To learn if a heat pump is right for your home, visit Massachusetts' Clean Energy Center's guides to air-source heat pumps and ground-source heat pumps. Mass Save® offers rebates on heat pumps up to $10,000 per home.
