Free Energy Assessment

For residential NSTAR customers intending to invest in energy efficiency upgrades to their 1-4 family home, Mass Save provides on-site Home Energy Assessments by trained Energy Specialists to evaluate existing conditions and make recommendations specific to your home.

The assessment focuses on weatherization (insulation & air leakage), mechanical systems (air conditioning, heating & hot water), major appliances and lighting to identify cost effective energy efficiency opportunities. Consequently, access to all areas of the building will be required on the day of your basement-to-attic assessment. This service does not include thermal imaging or blower-door testing, if you require these services read about the Enhanced Energy Assessment.

A typical assessment takes between 1½ to 2 hours to complete but depends on the specific home. All household decision makers should plan to participate in the assessment in order to gain an understanding of the recommended energy efficiency opportunities, their impact and the installation process necessary to implement the improvements. We also ask for you to prepare a year’s worth of utility information (electric, gas, oil, propane, etc.)

At the end of your Home’s Energy Assessment your Energy Specialist will provide you with information on any available utility incentives/rebates or available financing offers for the recommended energy efficiency improvements and explain the next steps necessary to implement the recommendations.
