Question Answers

We're seeing flickering lights and our breakers trip often. What should we do?

These are common signs of an overloaded or aging electrical panel, which we frequently address in Catonsville homes. We recommend a professional panel check. Our electricians will inspect your main panel and circuit breakers, test the grounding to ensure it meets current code, and diagnose any underlying wiring issues. This proactive approach can prevent safety hazards and often resolves persistent electrical problems.

I need an electric vehicle charging station installed at my home. Can you handle that?

Absolutely. We install EV charging stations, a service that's becoming increasingly popular in our area. Our process includes assessing your home's electrical panel capacity to ensure it can support the new load safely. If needed, we can perform a panel upgrade or install a dedicated circuit. We handle the entire installation, from the wiring to the final setup, ensuring your station is ready for reliable, everyday use.

My generator isn't switching on during a power outage. What's usually the problem?

In Catonsville, a frequent culprit for generator failure is an issue with the automatic transfer switch. This critical component can malfunction due to age, improper installation, or wear. As part of our generator services, we specialize in diagnosing and repairing transfer switch problems. We ensure the switch is correctly wired and functioning so your home automatically and safely transitions to backup power when the grid goes down.
