We performed comprehensive preventative maintenance on a Generac standby generator for a homeowner in Spring. Our team conducted a thorough inspection of the engine components, checked fluid levels, and verified the overall system health. We also reviewed the Evolution 2.0 controller logs to ensure the unit was performing optimally during its scheduled run times. To ensure reliable operation, we tested the electrical output and frequency using a Fluke multimeter and measured gas pressure with a Magnehelic gauge. We cleaned internal connections and verified the transfer switch functionality to guarantee seamless power transition during an outage. This routine service confirmed the system is ready to provide backup power whenever needed.
