Answer: How Much Heat Is Lost Through Duct Leaks in Vancouver Homes?
Duct leakage is a significant source of energy waste in many Vancouver homes. Studies show that typical duct systems in unconditioned spaces (crawlspaces, attics, basements) lose 20-30% of heated or cooled air through leaks at joints, connections, and holes. For a home spending $1,500 annually on heating, duct leakage costs $300-450 in wasted energy each year. Homes with ductwork running through unconditioned crawlspaces — common in Vancouver — are the most affected. Duct sealing with mastic (not duct tape, which fails over time) reduces leakage to 5-10%, saving $200-300 annually. A duct leakage test measures the total leakage and identifies the specific areas needing sealing.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
