We performed a comprehensive preventative maintenance service on a Generac home standby generator in Conroe. Our team conducted a full engine inspection and adjusted the valves to ensure proper mechanical timing and performance. We also tested the transfer switch and internal circuitry using a digital multimeter to confirm the system maintains correct voltage and frequency levels. During the service, we replaced the fouled spark plugs and the pleated air filter to improve engine efficiency. We installed a new Generac oil filter and recorded the service hours directly on the unit for accurate tracking. Our technicians also addressed battery terminal corrosion to ensure reliable starting during the next power outage.
