The Benefits of a No-Cost Home Energy Assessment
A no-cost Mass Save Home Energy Assessment is your first step toward a more comfortable, energy-efficient home. It’s also required to unlock available incentives and determine your home’s eligibility for upgrades.
By completing a no-cost assessment, you could gain access to rebates and incentives, including:
- 100% off air sealing
- 100% off insulation upgrades
- Rebates up to $15,000 for qualifying heating, cooling and water heating equipment upgrades
- Additional incentives to address any barriers that prevent weatherization work from moving forward
- No-cost energy-saving tools installed on the spot, like smart thermostats and low-flow showerheads
There’s no catch. These upgrades are offered to qualifying homes as part of a statewide effort to bring energy savings and comfort to more communities without the financial burden.
Rental properties with 1-4 units may also qualify for a no-cost, comprehensive upgrade package, including:
- No-cost air-source heat pumps*
- Up to 100% off health and safety barrier remediation
- A turnkey delivery experience, from project coordination through installation
* Only available for households using delivered fuels or electric resistance heating and buildings in which heat pumps are not expected to increase renters’ energy burden. Project details may vary.
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 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.

You get access to all eligible benefits like 75-100% off insulation, 100% off air sealing, 0% financing, up to $16,000 in heat pump rebates, and no-cost items.
