Repair vs. Replace: When It's Time for a New Furnace

When your furnace starts acting up, the first question is always the same: repair it or replace it? The answer depends on several factors.

The average furnace lasts 15 to 20 years with proper maintenance. If your system is under 10 years old, repairs almost always make sense. If it's over 15, replacement deserves serious consideration.

Multiply the age of your furnace by the cost of the repair. If the result exceeds $5,000, replacement is likely the smarter financial move. For example: a 16-year-old furnace needing a $400 repair = $6,400. Time to replace.

Frequent Repairs

If you've called for service twice in the past two years, the system is failing. Compounding repairs add up fast.

Rising Heating Bills

An aging furnace loses efficiency year over year. If your gas bills are climbing despite consistent usage, your system is working harder to produce the same heat.

Uneven Heating

Hot and cold spots throughout your home indicate the furnace can no longer distribute heat effectively.

Yellow Pilot Light

A healthy furnace burns blue. A yellow or flickering flame indicates incomplete combustion and possible carbon monoxide production — a serious safety issue.

Frequent Cycling

A furnace that turns on and off repeatedly without completing a heat cycle is short-cycling. This stresses the system.

AFUE Rating

Annual Fuel Utilization Efficiency measures how much fuel becomes usable heat. High-efficiency models reach 96-98%, which can cut your gas bill significantly.

Variable-Speed Blower

A variable-speed motor runs at lower speeds most of the time, reducing electricity consumption and improving comfort.
