This program is available to eligible customers who meet the following qualifications: Upstate New York homeowners living in residential 1-to-4 unit owner-occupied dwellings, who heat their homes with National Grid electric heat or National Grid natural gas heat.

  • You'll receive a custom Comprehensive Home Assessment (CHA) and up to two hours of air sealing, all for a $50 participation fee.
  • During your CHA, your home will receive an in-person, top-to-bottom assessment by a certified Energy Specialist, identifying money-saving air sealing, insulation and additional energy efficiency opportunities.
  • Sealing your home’s air leaks may increase the comfort of your home and cut energy use year-round. This simple energy efficiency improvement may also help your heating and cooling systems run more effectively. And as part of your CHA, you’ll receive up to two hours of valuable air sealing at no additional cost!
  • If your Energy Specialist indicates that attic insulation is recommended, you may be eligible for National Grid incentives of 50% of the pre-set installed cost of insulation, up to a $3,000 maximum.

The CHA and installation of air sealing and insulation will be performed by GreenHomes America: a participating EHSIP contractor who is professionally trained and certified by the Building Performance Institute (BPI).
