Your furnace just died in the middle of a Toronto winter. The technician gives you a quote for repairs, but mentions replacement as an option. Now you’re stuck with the tough question: do you fix it or replace it?

Here’s how to make the right call for your home and budget.

The 50% Rule: Your Starting Point

If the repair cost is more than 50% of a new furnace AND your unit is over 15 years old, replacement usually makes more sense. A new mid-efficiency furnace for a GTA home runs $3,000-$5,000 installed, so if you’re looking at a $2,000+ repair on an old system, you’re throwing good money after bad.

Signs It’s Time to Replace

Your furnace is 15-20 years old. Even if it’s running now, you’re on borrowed time. Parts become harder to find, and efficiency has dropped significantly since it was installed.

Frequent repairs adding up. If you’ve called for service 3+ times in the past two years, you’re bleeding money. Each repair is a band-aid on a failing system.

Heating bills keep climbing. An aging furnace can lose 20-30% efficiency. You might be spending an extra $30-50/month in gas compared to a new high-efficiency model.

Uneven heating in your home. Cold spots and rooms that never warm up properly mean your furnace is struggling to distribute heat effectively.

When Repair Makes Sense

Not every problem means replacement. Repair is the smart move when:

  • Your furnace is under 10 years old
  • It’s a single component failure (blower motor, ignitor, thermostat)
  • Repair cost is under $500
  • The system has been reliable with minimal service history

Common affordable repairs include:

  • Thermostat replacement: $150-300
  • Flame sensor cleaning: $80-150
  • Blower motor: $400-600
  • Ignitor replacement: $150-250

Energy Efficiency: The Hidden Factor

Today’s high-efficiency furnaces (95%+ AFUE) can cut your heating costs by 30-40% compared to older 60-80% AFUE units. In Toronto’s climate, that’s real money – potentially $400-700/year in savings.

If you’re replacing, that efficiency upgrade pays for itself over 5-7 years while keeping your home more comfortable.
