MyHEAT
Find out how much heating or cooling your home is losing
Air leaks in your home, especially around windows and doors, force your air conditioner and heater to work harder throughout the year. This can lead to higher energy bills and uncomfortable rooms.
The MyHEAT program, in partnership with Enbridge Gas, is here to help! Markham residents can view a free, personalized heat loss map of their home to identify air leaks.

See where your home could benefit from more insulation, air sealing or other energy efficiency upgrades. No home visits or assessments required.
This includes:
• An aerial heat loss map to pinpoint areas where air may be escaping from your home
• A heat loss rating to help you better understand how much heat is escaping
• Actionable steps to improve your home's energy efficiency
• Information on available rebates and incentives
