Duct leakage and ductwork pressure testing in Brampton

If some rooms never get warm in winter or cool in summer, the problem is often the ductwork, not the furnace or air conditioner. In the Toronto area, 59% of households heat with a forced-air furnace, so duct losses affect many Brampton homes.

Each house stands for one in ten of Brampton's 155,800 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. More snow in the drawing means more heating degree-days: a longer, colder heating season.

Who needs it in Brampton

In the Toronto area, 59% of households heat mainly with a forced-air furnace, 8% with a boiler and radiators, 5% with electric baseboards and 4% with a heat pump; natural gas is the main heating energy for 52% of households and electricity for 18% (Statistics Canada, 2023).

Of Brampton's 155,800 houses (single-detached, semi-detached, row houses and duplexes), 3% were built before 1961 and 33% 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, and leaky return ducts can pull in humid air. 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.

What this means in Brampton’s climate

Cold winters and hot, humid summers: seal the attic, dry the basement, plan cooling.

This region has real winters and hot, humid summers, so bills come from both heating and cooling. Natural gas heats most Ontario homes, while most Quebec homes use low-cost electricity. An EnerGuide evaluation here should cover air sealing and the attic, cooling and dehumidification, and keeping the basement dry before insulating it.

  • Right-size cooling to control humidity. In humid summers, an oversized air conditioner or heat pump cools quickly but shuts off before removing moisture, leaving rooms clammy. A heat pump replacing the air conditioner also covers much of the heating. Ask: Ask for a room-by-room heat-loss calculation and a duct and airflow check before replacing your air conditioner or furnace.

Duct leakage testing in Brampton: common questions

How much does duct leakage testing cost in Brampton?

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.
