Repair vs Replace: The Real Question
When a furnace breaks down, most homeowners ask: “Should I fix it or replace it?”
The right answer depends on age, repair cost, and reliability.
When Repair Makes Sense
Repair is usually the better option when the furnace is under 10 years old, repair cost is low, the system has been well maintained, and no major component failures exist.
When Replacement Makes More Sense
Replacement is often better when the furnace is over 15 years old, repairs are frequent, major components fail (heat exchanger, blower motor), or energy bills are rising.
The 30–40% Rule
A common industry guideline: if repair costs are 30–40% or more of replacement cost, replacement is usually the smarter investment.
Warranty Consideration
Older systems often have limited or expired warranty coverage, no labour protection, and higher out-of-pocket repair costs.
New systems often include stronger warranty protection and lower long-term risk.
