Who needs it in Vancouver
In the Vancouver area, 32% of households heat mainly with a forced-air furnace, 31% with electric baseboards, 12% with a boiler and radiators and 5% with a heat pump; natural gas is the main heating energy for 42% of households and electricity for 39% (Statistics Canada, 2023).
Of Vancouver's 115,455 houses (single-detached, semi-detached, row houses and duplexes), 31% were built before 1961 and 62% before 1991, according to the 2021 Census. Ducts in older houses often run through unheated spaces with taped or unsealed joints, and supply runs to the far rooms are the first to suffer.
The same leaks cost you in summer when the ducts carry cooling: air from a central air conditioner or heat pump that escapes into an attic, garage or crawlspace is cooling you paid for. Sealing and balancing the ducts helps in both seasons, and it's worth doing before a new heat pump goes onto old ductwork.
What the test shows
- Total duct leakage, as a share of the system's airflow, measured by pressure-testing the ductwork with a calibrated duct-pressurization fan.
- Airflow at each register, which explains why one bedroom is always cold.
- Whether sealing and balancing will fix comfort problems before you buy bigger equipment.
What it costs
About $200–$450 (a September 2026 planning range; quotes vary). It isn't part of a standard EnerGuide evaluation, so ask for it when you book if comfort is your main complaint.
Coastal BC Lower Mainland and Vancouver Island
What this means in Vancouver’s climate
Mild, wet winters and summer heat waves: fix moisture first, then cooling and heat pumps.
Coastal BC has Canada's mildest winters, but heavy rain from fall to spring soaks walls and roofs, and summer heat waves are now a health risk. Heating needs are the lowest of any region we cover, so damp, drafts and overheating are the common complaints. An EnerGuide evaluation here should look for moisture problems before any air sealing or insulation, then plan a heat pump that heats and cools.
- Get ready for smoky days. Smoke reaches the coast too: Vancouver logged 171 hours of smoke and haze in September 2020. A good filter or air cleaner lets you keep windows shut. Ask: Ask whether your furnace or air handler can take a MERV 13 filter, or which certified portable air cleaner suits your main living area.

NRCan-licensed service organizations serving Vancouver
A service organization is a company that Natural Resources Canada (NRCan) licenses to deliver EnerGuide evaluations; its registered energy advisors do the home visit. Duct leakage testing isn't part of a standard EnerGuide evaluation. Some of these organizations offer it, as do HVAC contractors with duct-testing equipment, so ask when you call.

Duct leakage testing in Vancouver: common questions
How much does duct leakage testing cost in Vancouver?
Plan on about $200–$450. It is usually a separate service from an EnerGuide evaluation.
Is duct cleaning the same thing?
No. Cleaning removes dust; it doesn't find or seal leaks. A leakage test measures where air is lost.
What is ductwork pressure testing?
The same thing as a duct leakage test: registers are sealed, a calibrated fan pressurizes the ducts, and the airflow needed to hold the test pressure shows how leaky they are.
Should I close vents in unused rooms?
Usually not. Closing registers raises duct pressure and can increase leakage elsewhere in the system.
