Why Heat Pumps?

Heat pumps are cost-effective, energy-efficient, and market-ready technologies that transform how your home uses energy. These technologies can help save you money on your utility bills and also significantly help Lexington decrease its overall carbon footprint, benefiting the community. 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. Mass Save® offers rebates on heat pumps up to $10,000 per home.

As an added incentive, residents living in single family home, in an individual apartment, or in a residential condo who use permanently installed electric heating equipment as the principle heating system are eligible for a reduced electric rate through Eversource (A4 - Residential Space Heating, which is around 1.5 cents per kWh cheaper than the default rate).

The Lexington Average Annual Heating Costs chart is based on current utility and fuel prices as of stated date and average heating load of newest homes in Lexington (88.35 MMBtu).
