Generator repair is rarely just a box outside the house. Problems can come from the battery, control board, transfer switch, breaker, gas supply, load sizing, wiring, or maintenance history. CSW evaluates the complete standby power system so the repair addresses the real failure point.
If the generator is undersized, poorly maintained, or connected to an aging electrical panel, repair may only solve part of the problem. CSW can compare the repair path against a new standby generator installation, an electrical panel upgrade, or gas-line corrections handled by our licensed plumbing team.
For a Generac system, have the model, serial number, controller message and any maintenance records ready. Controller behavior and service intervals vary by model, so the exact manual matters. Notes about recent utility work, an extended outage or newly added appliances help explain why an existing system behaves differently. Keep covers, safety interlocks and control wiring intact.
After an outage, check from a safe distance for visible damage, flooding, unusual odor or an alarm. Stay away from exposed or wet electrical equipment and never open a transfer switch. If you smell gas, move to a safe location and contact the utility or emergency services. A carbon-monoxide alarm means leave and get emergency help.
Possible causes include transfer-equipment, control or electrical connection problems. A running engine does not confirm power is reaching the supported circuits. Have a qualified professional diagnose it; do not open the transfer switch.
An exercise cycle checks different conditions from an actual transfer or load test. Readiness also depends on maintenance, fuel supply, battery condition, transfer equipment and the planned loads.
