The answer to 'how long will furnace repair last' is that the duration of a furnace repair can vary significantly depending on the specific issue and the extent of the repair needed. Generally, a well-maintained furnace can last anywhere from 10 to 15 years before major repairs or replacement is required. However, smaller repairs such as replacing a thermostat, blower motor, or ignitor may only last a few years before needing attention again.
The longevity of a furnace repair also depends on factors like the age and condition of the furnace, the quality of the repair work, and how well the homeowner maintains the system with regular tune-ups and filter changes. Proper maintenance is key to extending the lifespan of furnace repairs and the overall system.
