What is a Home Energy Assessment and Why Do You Need One?

  • A home energy assessment, sometimes called a home energy audit, reveals how your home consumes and loses energy. During a Mass Save® energy audit in Marlborough, one of our certified energy specialists walks through your home, identifying areas where you could be saving energy (and money). You receive a detailed custom report outlining findings, plus potential access to Mass Save rebates and enhanced incentives for income-qualified households. Rebates vary by installation type and system size.
  • Many Marlborough homeowners have questions about drafty rooms, high energy bills during New England winters, inadequate insulation, and whether their heating and cooling equipment works efficiently. A home energy assessment in Marlborough, MA answers these questions while identifying energy-saving opportunities. You must complete the home energy assessment through a Mass Save qualified provider like Endless Energy to unlock rebate and HEAT Loan eligibility.
  • The assessment takes about two and a half hours, depending on your home’s size and complexity. For Marlborough residents dealing with the region’s temperature extremes, from humid summers to freezing winters, understanding where your home loses energy makes a significant difference in both comfort and cost.

We've used Endless Energy for a few heating system maintenance rounds and updates. Most recently, Mike Heil helped us solve a cold zone problem in an old house. Mike could not have been more thorough, patient or gracious. It was refreshing to work with someone obviously so expert in his field but who acted like he had all day to think through the problem and review every angle with us. He and team made this process far less stressful than other upgrades we've been through.
