The answer to 'lifespan of generator installation' is that a properly installed and maintained home generator can last 15-30 years on average. The lifespan of a generator installation depends on factors like the quality of the generator, how often it's used, and the maintenance schedule. High-quality standby generators that are serviced regularly can reach the upper end of that range, while portable or budget generators may only last 10-15 years with heavy use.
Regular maintenance like oil changes, air filter replacements, and checking for wear and tear is crucial to maximizing the lifespan of a home generator installation. Homeowners should also consider the environment the generator is installed in, as extreme temperatures, moisture, or other environmental factors can impact the longevity of the system.
