Furnace Age
A furnace near or past its expected service life is a stronger candidate for replacement, especially after a major component failure.
Repair Frequency and Scope
Frequent repairs, or a single major repair such as a cracked heat exchanger, shift the decision toward replacement.
Efficiency
An older low-efficiency furnace costs more to operate. A replacement may reduce operating cost over time. See our AFUE explainer.
Safety
A cracked heat exchanger can leak carbon monoxide. If a technician identifies this, replacement is the safe path.
When to Call a Professional
Request an assessment so a technician can evaluate the unit and give a personalised recommendation.
