Duct leakage testing in Saint-Jean-sur-Richelieu

If some rooms never get warm, the problem is often the ductwork, not the furnace. In Quebec, only 11% of households heat with a forced-air furnace, so the test matters mainly for homes with ducts or those adding a ducted heat pump.

Who needs it in Saint-Jean-sur-Richelieu

In Quebec, 54% of households heat mainly with electric baseboards, 16% with a heat pump, 11% with a forced-air furnace and 4% with a boiler and radiators; electricity is the main heating energy for 70% of households, natural gas for 5% and wood for 4% (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 Saint-Jean-sur-Richelieu's 26,960 houses (single-detached, semi-detached, row houses and duplexes), 19% were built before 1961 and 60% 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.

Duct leakage testing in Saint-Jean-sur-Richelieu: common questions

How much does duct leakage testing cost in Saint-Jean-sur-Richelieu?

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.
