Many of us live in homes built before 1970. If you live in one of these older homes, the insulation in your walls may not meet modern energy efficiency standards. An older home probably has 250% more air leakage than a home built today — that is a lot of cold air sweeping into your home making it uncomfortable and expensive to heat.

How can you tell if your walls are properly insulated and air sealed? Start with a no-cost virtual home energy assessment . 

Take advantage of the 75% reimbursal on insulation (and other weatherization)! MassSave, a sponsored energy efficiency program, will reimburse all customers for any needed in sulation at 75%.  

If you had an assessment in the last two years and already have a Mass Save insulation recommendation, you can still qualify for the incentive! Check with the company who did that assessment to check if you qualify, and if you do, the incentive will be applied to the existing assessment.

MassSave also subsidizes approved air sealing work. It also offers a 0% loan program for financing HVAC and energy efficiency measures. The energy efficiency professional can give you more details during the assessment.  

Want to go deeper? There are many more energy efficient improvements you can make beyond insulation and air-sealing, and MassSave has additional incentives for renovations and additions, as well as 0% loans fo r greater energy efficiency measures.
