The decision to repair or replace a furnace is one of the most common questions Canadian homeowners face. The answer depends on four key factors: the age of the furnace, the cost of the repair, the
efficiency of the current unit, and the frequency of past breakdowns. Our quiz scores each factor and provides a weighted recommendation.
HVAC professionals often use the
“5,000 Rule” as a quick guide: multiply your furnace’s age (in years) by the
repair cost (in dollars). If the result exceeds $5,000,
replacement is generally the more economical choice.
