How Long Does a Furnace Last?
Most furnaces have a lifespan of 20 to 30 years. However, this doesn’t mean you can wait that long to replace yours. After about 15 years or so, you may need to consider a furnace replacement if your unit has been experiencing significant problems and requires frequent repairs.
You can extend the lifespan of your furnace by performing regular maintenance, including changing the filters and cleaning the burners. Also, consider hiring an HVAC contractor to perform annual inspections and a tune-up before the winter season.
