How does the no-cost Home Energy Assessment work?

During the assessment a certified Energy Specialist will visit your home to identify opportunities to save energy, including:

  • Performing a safety check of your heating system*
  • Installing eligible energy- and water-saving devices
  • Assessing the potential to improve air sealing or insulation in your walls, attic* and basement*
  • Providing you with a customized report of the opportunities to increase the energy efficiency of your home and information about available financial rebates and incentives

*If accessible

What are the benefits of a Home Energy Assessment?

There are benefits available for residents of all income levels.

Renters can receive energy and water saving devices installed at no-cost, such as:
  • High efficiency shower heads and faucet aerators
