Each house stands for one in ten of Trois-Rivières's 39,825 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 Trois-Rivières

In the Trois-Rivières area, 59% of households heat mainly with electric baseboards; electricity is the main heating energy for 79% of households (Statistics Canada, 2023).

Of Trois-Rivières's 39,825 houses (single-detached, semi-detached, row houses and duplexes), 21% were built before 1961 and 68% 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 Trois-Rivières: common questions

How much does duct leakage testing cost in Trois-Rivières?

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.
