Duct leakage testing in Gatineau

If some rooms never get warm, the problem is often the ductwork, not the furnace. In the Gatineau (Quebec) part of the Ottawa–Gatineau region, 30% of households heat with a forced-air furnace, so duct losses affect many Gatineau homes.

Each house stands for one in ten of Gatineau's 80,110 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. Snowfall scales with heating degree-days.

Who needs it in Gatineau

In the Gatineau (Quebec) part of the Ottawa–Gatineau region, 45% of households heat mainly with electric baseboards and 30% with a forced-air furnace; electricity is the main heating energy for 60% of households and natural gas for about 22% (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 Gatineau's 80,110 houses (single-detached, semi-detached, row houses and duplexes), 14% were built before 1961 and 58% 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 with a 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.

Duct leakage testing in Gatineau: common questions

How much does duct leakage testing cost in Gatineau?

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.

Should I close vents in unused rooms?

Usually not. Closing registers raises duct pressure and can increase leakage elsewhere in the system.
