Duct leakage and ductwork pressure testing in Saanich

If some rooms never get warm, the problem is often the ductwork, not the furnace. In the Victoria area, only about 16% of households heat with a forced-air furnace, so the test matters mainly for homes with ducts or those adding a ducted heat pump.

Each house stands for one in ten of Saanich's 37,620 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. Rain marks the mild, wet winters: here moisture, not deep cold, is the main winter risk.

Who needs it in Saanich

In the Victoria area, 37% of households heat mainly with electric baseboards, 23% with a heat pump and about 16% with a forced-air furnace; electricity is the main heating energy for 46% of households and natural gas for 23% (Statistics Canada, 2023).

Electric baseboards outnumber furnaces here, and a baseboard-heated house has no ducts to test. The test matters if you have forced air, or before you add a ducted heat pump to existing ductwork.

Of Saanich's 37,620 houses (single-detached, semi-detached, row houses and duplexes), 28% were built before 1961 and 78% 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.

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 Saanich’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.

Duct leakage testing in Saanich: common questions

How much does duct leakage testing cost in Saanich?

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.
