A backup generator that hasn’t been serviced often fails at the worst moment. Picture a tornado warning at 2 a.m., the power drops, and your standby unit cranks once and goes silent. The cause is usually a dead battery, a failed transfer switch, or corroded control wiring that nobody checked. A generator service Huntsville AL electrician finds those problems in daylight, before the storm. For you, that means a cool house, a running sump pump, a cold refrigerator, and no backfeed danger to utility line crews.
