The Town is working to help Carlisle residents lower energy usage, make their homes more comfortable, and save money on energy costs.

In line with the Town’s sustainability efforts, Carlisle has partnered with HomeWorks Energy, a Mass Save® partner, to help residents make their homes more efficient, starting with a no-cost assessment.

During your assessment, a Home Energy Specialist will review your home’s energy performance and show you how to save money and energy year-round.

Benefits of an assessment include a no-cost custom home energy report, 100% off sealing air leaks in your home, 75-100% off new insulation, up to $10,000 in heat pump rebates, 0% financing, and no-cost energy-saving items such as programmable thermostats and water-saving devices.

Together, we can make Carlisle sustainable, while enjoying the benefits of energy efficiency in our homes.

What to Expect from a Home Energy Assessment

We’ll work with your utility provider to get approval for the Home Energy Assessment. If we need more information from you for the approval, we’ll call you within 24 hours.


Your Home Energy Specialist will be at your home or will call you 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.
