Many of us live in underinsulated, leaky homes. There’s a lot of air sweeping into and through our homes, making them uncomfortable and expensive to heat and cool! It’s easy to feel the pinch of this, especially in the winter.

That struggle isn’t necessary: addressing this will most likely cost you nothing and save you a lot!

How can you tell if your walls are properly insulated and air sealed?  Start with a no-cost  home energy assessment. For perspective, an older home probably has at least 250% more air infiltration than a new construction home today.

Take advantage of available reimbursements. Mass Save, a state sponsored energy efficiency program, will reimburse all customers for any needed insulation at 75%.  If you made an upgrade to a heat pump, heat pump hot water heater, your home insulation, or added solar to your home before December 31st, 2025, you may still be eligible or federal tax credits for 30% off the costs. You can find details and added information from the United States Department of Energy and the IRS.

MassSave subsidizes approved air sealing work. You can find out more about their insulation and air sealing programs here. It also offers a 0% loan program for financing HVAC and energy efficiency measures. The energy efficiency professional conducting your assessment can provide you with more details.

Want to go deeper? There are many more energy efficient improvements you can make beyond insulation and air-sealing, and Mass Save has additional incentives for renovations and additions, as well as  0% loans for greater energy efficiency measures. Air sealing and insulation is generally a necessary first step for other carbon reducing measures.
