The answer to 'lifespan of generator' is that the average lifespan of a home standby generator is 15-30 years, depending on proper maintenance and usage. Standby generators are designed for long-term, continuous use and can provide reliable backup power for many years with regular service. However, the actual lifespan can vary based on factors like the generator's size, quality, and how often it's used.
Proper maintenance is key to maximizing a generator's lifespan. This includes regularly changing the oil, air filters, and other consumable parts, as well as testing the generator under load to ensure it's running efficiently. With diligent care, many standby generators can operate for 20-25 years or more before needing replacement.
