Repair or Replace Furnace? Important Signs to Know
A furnace problem should be evaluated carefully because heating performance, operating cost, and household safety are all important.
When Repairing Makes Sense
Repair may be suitable when the furnace is relatively new and the issue involves a thermostat, igniter, blower component, filter, or other replaceable part.
When Replacement May Be Better
Consider replacement when the furnace is around 15 to 20 years old, breaks down repeatedly, heats unevenly, or causes rising energy bills. A cracked heat exchanger is a serious safety concern and may require replacement.
Look at Total Cost
Compare the repair estimate with the price, efficiency, warranty, and expected lifespan of a new furnace. Include installation, ventilation, and any required upgrades.
Safety Comes First
If you smell gas, see soot, hear unusual sounds, or suspect carbon monoxide, turn off the system if safe to do so and contact a qualified professional immediately.
