Home Energy Performance Program

The Home Energy Performance Program takes a holistic approach to saving energy in your home. ENERGY STAR® estimates that you can save up to 20% on heating and cooling costs by adding insulation to the walls, basement, pipes, attic, attic stairs, crawl space and rim joists in your home.

An in-home energy audit is the first step in making your home more efficient. An audit will evaluate your home’s characteristics and energy usage and provide recommendations on ways you can improve efficiency and save money. There is a $100 fee for this service, which includes diagnostic testing for air and duct leakage ($100 audit fee is reimbursed if you move forward with weatherization recommendations.)

If you decide to move forward with the program, you are also eligible to receive:

  • A rebate of 100% of the installed cost of air sealing in your home*
  • A rebate of 75% of the installed cost of insulation*
  • 2% financing through select local financial institutions
  • 0% on bill financing available through Liberty

*$6,000 MAXIMUM for air sealing and insulation combined. 


It all starts when you complete the Home Heating Index application at You’ll get customized results for your home and heating situation. If you qualify for the program, the site will display a link to an enrollment application and instructions. For details visit
