Frequently Asked Questions

Why does my arc fault breaker in Santa Rosa keep tripping, and can an inspection help?

Arc fault breakers in older Santa Rosa homes can trip due to aging wiring, shared neutrals, or even appliances like vacuum cleaners. A professional electrical inspection from Mark Horner Electric can pinpoint the exact cause—whether it's a wiring fault, a circuit overload, or a device compatibility issue—and provide a safe, code-compliant solution to stop the nuisance trips.

My lights are flickering in my Santa Rosa home. Is this a serious issue, and what does an inspection involve?

Flickering lights often indicate loose connections, which are a fire hazard and common in our area. A comprehensive electrical inspection will check all connections at switches, outlets, and within the main panel. We'll identify any overheating, arcing, or faulty wiring to resolve the flickering and, more importantly, eliminate the underlying safety risk.

What specific things do you look for during a Santa Rosa home electrical inspection related to these common problems?

For Santa Rosa homes, our inspection focuses on local concerns: we check for loose terminal connections in panels and devices that cause flickering, test AFCI breakers for proper function and nuisance trip sources, examine wiring for age-related degradation, and ensure the system can handle modern electrical loads safely, providing you with a clear report and prioritized recommendations.
