The answer to 'lifespan of generator' is that a properly maintained generator can last 15-30 years or more. Generators are durable machines, but their lifespan depends on factors like usage, maintenance, and environmental conditions. With regular maintenance and proper care, a generator can provide reliable backup power for decades.
Factors that affect generator lifespan include the quality of the unit, how often it's used, the type of fuel it runs on, and how well it's maintained. Standby generators that only run during power outages typically last longer than portable generators used more frequently. Proper maintenance like oil changes, air filter replacements, and regular testing are key to maximizing a generator's lifespan.
