Combustion safety testing in Moncton

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.

How Moncton is built

Moncton's houses by when they were built Ten house shapes, one for each tenth of Moncton's 23,365 houses. Before 1961: 24%, 1961–1990: 37%, 1991–2000: 12%, 2001 or later: 28%. Older houses glow hotter.

Each house stands for one in ten of Moncton's 23,365 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 Moncton

In the Moncton area, 34% of households heat mainly with electric baseboards; electricity is the main heating energy for 42% 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 New Brunswick

We found no New Brunswick rule requiring CO alarms in existing homes; new construction follows the 2020 National Building Code.

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.
