Repair or Replace? How to Decide About Your Furnace
When a major furnace component fails, the repair-or-replace decision can feel stressful. Here is a straightforward framework.
Consider Repair When
- The furnace is under 12–15 years old
- The problem is isolated (ignitor, sensor, capacitor, blower motor)
- Repair cost is well under half the price of a new system
- The heat exchanger is intact and the system has been well maintained
Lean Toward Replacement When
- The unit is 15–20+ years old
- You face recurring expensive repairs
- Efficiency is poor and energy bills keep climbing
- The heat exchanger is cracked (gas furnaces)
- You want modern features, quieter operation, and higher efficiency
