Lexington Residents:

Make your home more comfortable and reduce your energy use while saving money.

Referral Code: lexington

The Town of Lexington is committed to achieving net zero greenhouse gas emissions by 2050, which will require action from residents and businesses. In Lexington, 73% of greenhouse gas emissions come from our buildings, mainly from the energy required to heat and cool them. Making a home more energy-efficient can go a long way in saving energy and reducing emissions.

The Town has partnered with HomeWorks Energy, a longtime Mass Save ® partner, to help residents make their homes more energy efficient, which can save money and increase comfort too. This effort supports LexElectrify, the Town’s campaign to empower community members to take climate action.

Through a Home Energy Assessment, a HomeWorks Energy Specialist will identify energy-saving opportunities, offer 75-100% off insulation work, 100% off air sealing work, and connect you with relevant Mass Save rebates and other financial incentives.

Together, we can make Lexington a more sustainable place and enjoy the benefits of energy efficiency!

Your Home Energy Specialist will be at your home at your scheduled time and will begin your Assessment. The assessment typically takes between 2-3 hours.

You will learn how your home consumes and loses energy and you’ll receive a custom home energy report, along with other recommendations to save like insulation or air sealing upgrades.
