Common Electrical Questions

Expert insights for homeowners in the Main Line and Greater Philadelphia.

Do you provide emergency electrical repairs in the Main Line?
Yes. We offer fast-response troubleshooting and emergency repairs across the Main Line, including Villanova, Ardmore, and Wayne. Whether it's a tripping breaker or a complete power loss, our team is equipped to handle residential safety issues quickly.
How do I know if my electrical panel needs an upgrade?
If you are experiencing flickering lights, frequently tripping breakers, or are planning to install a high-draw appliance like an EV charger, a panel upgrade is likely necessary. Many older homes in Montgomery and Delaware County were built with 100-amp service, which often needs modernization to 200-amp to safely support modern electronics.
Are your services fully insured for residential work?
Absolutely. 21 Century Electrical Services is fully insured for all residential projects. We prioritize safety and property protection, ensuring that every job—from outlet repairs to EV charger installations—is code-compliant and secure.
Can you install Tesla and Universal EV chargers?
Yes, we specialize in Level 2 home charging station installations. We have extensive experience fitting Tesla Wall Connectors and universal chargers in suburban garages and driveways, ensuring a tidy, high-speed charging setup for your electric vehicle.
What is your "Clean Work Guarantee"?
We understand that your home is your most valuable asset. Our technicians use floor protectors, maintain tidy workspaces, and perform a complete cleanup after every job. We treat your property with the same respect we would our own.
Do you handle permits for larger projects?
For projects requiring municipal permits and inspections, we coordinate everything through our network of licensed partners. This ensures your project is 100% legal, safe, and meets all local Philadelphia and suburban building codes.
