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

Most electrical work requires a licensed electrician and a permit. Unlicensed electrical work is not only dangerous but can void your homeowner's insurance. Sunnyvale Electric is fully licensed (CA Lic #1026941) and handles all permitting as part of the job.

How much does an electrician cost?

Costs vary depending on the type and complexity of the job. We provide free, no-obligation quotes so you always know the price upfront before any work begins.

Do you offer free estimates?

Yes — Sunnyvale Electric offers free, no-obligation estimates on all jobs. Contact us by phone at 916-847-4014 or through our quote form.

Are you a certified Tesla Wall Connector installer?

Yes — Sunnyvale Electric is a certified Tesla Wall Connector and Powerwall installer. We also install all other EV charging brands and advanced battery backup systems.

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

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.

Why does my circuit breaker keep tripping?

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.

Why are my lights flickering?

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.
