Do I need a licensed electrician or can I do it myself?

Question 5

Do I need a panel upgrade to install an EV charger?

Accepted Answer

Not always. We evaluate your existing panel capacity during the estimate. If your panel can support the additional load, no upgrade is needed. If it can't, we'll walk you through the options before any work begins.

Question 6

How do I know if I need a panel upgrade?

Accepted Answer

Signs you may need a panel upgrade include frequently tripping breakers, flickering lights, burning smells near the panel, a panel that feels warm to the touch, or if your home still has a fuse box.

Question 7

Why does my circuit breaker keep tripping?

Accepted Answer

A breaker that keeps tripping usually means the circuit is overloaded, there's a short circuit, or the breaker itself is failing. If it trips repeatedly, call a licensed electrician as it may indicate a serious wiring issue.

Question 8

Why are my lights flickering?

Accepted Answer

Flickering lights can be caused by a loose bulb, faulty light switch, overloaded circuit, or loose wiring connections. If multiple lights flicker throughout your home, have it inspected by a licensed electrician as it could be a fire hazard.
