GSHA Services, LTD performed a standby generator service visit at a rural home on Barber Lane in Woodstock, IL. Whole-home generators need annual maintenance to be ready for the next storm outage, so our generator technician performed a full service: changed the engine oil and oil filter, replaced the air filter and spark plugs, inspected the battery and charger, checked the automatic transfer switch and control panel for fault codes, cleaned the enclosure and verified the weekly exercise schedule. We then ran the generator under load and confirmed proper voltage, frequency and transfer-switch operation. A serviced generator starts when the utility fails and protects sump pumps, well pumps, furnaces and refrigerators for homes outside city water and power backups. GSHA Services is a factory-trained generator dealer offering Generac and Kohler generator installation, repair and annual maintenance plans in Woodstock, Bull Valley, Harvard, Marengo, Crystal Lake, McHenry, Wonder Lake and throughout McHenry County, Illinois.
