Each house stands for one in ten of Abbotsford's 37,705 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.

Why air leakage matters in Abbotsford

Abbotsford gets about 2,760 heating degree-days a year and has a winter design temperature of −5.9°C, according to NRCan's HOT2000 climate data for Abbotsford. That's the 2nd-lowest heating demand of the 70 cities we cover.

Of Abbotsford's 37,705 houses (single-detached, semi-detached, row houses and duplexes), 6% were built before 1961 and 52% before 1991, according to the 2021 Census. Older houses usually test leakier than newer ones, and an EnerGuide report compares your result with homes of the same era, so you can see whether your house is typical or a problem.

After you seal: two checks

  • Combustion safety. In the Abbotsford-Mission area, the main heating energy is natural gas for 57% of households. A tighter house changes how fuel-burning appliances vent, so the spillage check should be repeated after serious air sealing. Combustion safety testing in Abbotsford
  • Radon. Sealing shifts the pressure balance between the house and the soil. Health Canada's 2012 survey found 3% of 100 homes tested in the Fraser East Health Service Delivery Area health region above the guideline. The larger 2024 Cross-Canada survey reports 3.4% (1 in 29) of houses at or above the guideline for the Abbotsford - Mission, BC (Abbotsford-Mission CMA) metro area. Test before and after big air-sealing jobs. Radon testing in Abbotsford

What it costs in Abbotsford

A blower door test is part of every EnerGuide evaluation rather than a separate purchase. There's no provincial price list; the City of Nanaimo quotes $400–$500 as typical for an existing home. Several B.C. municipalities subsidize evaluations for their residents (see local programs below).

How the test works

  • A calibrated fan is fitted into an exterior door and pulls air out until the house is at 50 pascals, the standard test pressure.
  • The result is air changes per hour at 50 Pa (ACH50): how many times an hour the whole volume of air would leak out and be replaced at that pressure.
  • While the fan runs, you and the advisor walk the house and feel for leaks at the attic hatch, rim joists, pot lights, trim and plumbing and wiring penetrations.
  • A second test after the work shows what changed, and it is what most rebates pay on.

How much does a blower door test cost in Abbotsford?

What is a good blower door result?

Lower is better. Your EnerGuide report compares your air changes per hour at 50 Pa with homes of the same era, which is more useful than a single target number.

Does air sealing affect radon?

It can. Tightening a house changes the pressure difference with the soil, so test for radon before and after major air sealing.
