We performed a comprehensive preventative maintenance service on a Generac Guardian 22kW standby generator for a homeowner in Spring. Our team inspected the electrical service disconnect, the automatic transfer switch, and the gas meter connections to ensure the entire system was ready for power outages. We also conducted thorough system testing using digital clamp meters to verify voltage and operational performance. The service included replacing the engine oil filter and air filter to maintain optimal engine health and efficiency. We also installed a new battery with protective terminal treatment to prevent corrosion and ensure reliable starting power. These routine updates help extend the life of the unit and provide the homeowner with peace of mind during storm season.
