Energy Star

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). Homes heated with oil, propane, wood, natural gas, kerosene, or electricity may qualify.

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 Utilities

Please note due to high demand, Liberty customers may need to wait longer than usual for an appointment.
