Combustion safety testing in Red Deer

A combustion safety test checks that your furnace, water heater and fireplace vent their exhaust outside instead of into the house, which matters most right before and after you tighten the house up. In the Red Deer area, the main heating energy is natural gas for 83% of households.

Each house stands for one in ten of Red Deer's 31,405 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 it matters in Red Deer

In the Red Deer area, 81% of households heat mainly with a forced-air furnace; natural gas is the main heating energy for 83% of households (Statistics Canada, 2023).

The risk rises after air sealing: a tighter house plus a strong exhaust fan or dryer can pull exhaust back down a chimney. That's why advisors test for spillage during an evaluation and why it should be repeated after serious tightening.

The CO alarm rule in Alberta

Alberta requires CO alarms in new homes with a fuel-burning appliance or attached garage; for existing homes the province calls them highly recommended rather than mandatory.

What the check involves

  • Worst-case depressurization: exhaust fans and the dryer on, doors set to make the appliance room as negative as it gets.
  • A spillage and draft check at each appliance, with a CO reading.
  • A plan if anything fails: often a sealed-combustion appliance or a fix to the venting, done by a licensed gas or oil technician.
