We performed comprehensive preventative maintenance on a Generac standby generator for a residential property in Houston. Our team conducted a full system inspection, including a check of the Evolution 2.0 controller and the automatic transfer switch to ensure the home remains protected during power outages. The service included replacing the oil filter and verifying the internal battery health and electrical connections. We also performed voltage testing on the transfer system, confirmed the weekly exercise schedule, and cleared maintenance alerts on the digital display. These steps ensure the standby system operates at peak efficiency and is ready to activate if the local grid fails.
