Who Qualifies for a No-Cost Assessment?

To qualify, you must live in a single-family home, townhouse, or unit within a multi-family property (1-4 units) served by a participating utility, such as Eversource, National Grid, Unitil, or Berkshire Gas.

Eligibility for rebates and incentives is determined by specific program criteria, which may include your utility provider, property type, and household income.

Homeowners are eligible, and income-qualified households may be able to receive enhanced benefits, such as 100 percent coverage for recommended upgrades.

Preparing for the Visit

Before the assessment, make sure the Mass Save Energy Specialist can access your attic, basement, HVAC systems, and any crawl spaces. The assessment may be conducted in person or virtually, depending on your preference and availability. Close all doors and windows, and have recent utility bills available. The visit typically lasts 1.5 to 2 hours, depending on the size of the home. Your Energy Specialist will conduct a full walkthrough and explain their findings as they go.

What Happens During a Mass Save Assessment?

The Energy Specialist will begin with a brief conversation to understand your comfort concerns and energy goals. Next, they’ll conduct a series of diagnostic tests:

  • Blower Door Test: A large fan is temporarily installed in an exterior doorway to measure how much air is leaking from your home. This helps identify air leaks around windows, doors, and vents, showing where air sealing is needed.
  • Thermal Imaging Scan: Using infrared cameras, the specialist locates areas with poor insulation or thermal loss, such as cold spots in walls or ceilings.
  • Visual Inspection: The specialist checks your attic, basement, windows, doors, ductwork, and insulation levels. They’ll also inspect your water heater, checking its age and efficiency, and look at heating and cooling equipment to see if upgrades could improve efficiency.

Each test provides detailed insight into how energy is used and lost in your home. The Energy Specialist may also recommend installing advanced power strips, low flow showerheads, and faucet aerators programmable thermostats to further improve efficiency.

Understanding Your Personalized Energy Saving Report

After the walkthrough and testing, you’ll receive a customized energy report. This includes a summary of findings, estimated energy savings, and a list of recommended upgrades—ranked by impact and return on investment and aimed at lowering your energy bills. It will also include rebate opportunities and next steps.

Leveraging financial incentives reduces upfront costs and accelerates payback periods for home improvements. Homeowners may also qualify for additional rebates on select energy-efficient upgrades, providing extra savings beyond standard offers. The Mass Save program offers rebates for key upgrades that improve efficiency, comfort, and long-term energy savings.
