Electric SF - San Mateo's Certified Electrical Company

Flickering lights in older San Mateo homes are often due to loose wire connections in outlets, switches, or the main panel, which can be a fire hazard. They can also signal an overloaded circuit. Electric SF diagnoses the root cause by inspecting your wiring and panel. We then securely repair loose connections or recommend and install a panel upgrade if needed, restoring safe, stable power throughout your home.

Installing a home EV charger in San Mateo typically requires a dedicated 240-volt circuit from your electrical panel. Our electricians first perform an inspection to ensure your panel has the capacity and is up to current code. We then handle the permit process, run the proper wiring, and install the charging unit in your preferred location, like a garage. This ensures a safe, efficient setup for your vehicle.

Panels need repair if you're experiencing frequent breaker trips, buzzing sounds, or a burning smell—signs of a failing system. Replacement is often recommended for older panels in San Mateo that can't handle modern electrical loads or lack safety features. We assess your panel's condition and capacity. If an upgrade is needed, we install a new, properly sized panel that safely meets your home's current and future energy demands.
