How we troubleshoot

Your description. When it happens, what's running, what changed recently. This often points straight at the circuit.

Panel check. Breakers, connections, signs of heat, and the main and neutral.

Circuit testing. We isolate the circuit and test for shorts, ground faults, voltage drop and loose connections.

Clear repair price. We explain the cause and give you the fix and the price before doing it.

Repair and re-test. We confirm the fault is gone, not just hidden.

$175 – $400

These are approximate ranges, not quotes. They're based on typical Sacramento-area jobs. Your price depends on what we find at your home: panel condition, distance, access and permit fees. You'll get a clear price before any work starts.

A simple fix, like a failed GFCI or a loose connection, is usually one visit. Faults in walls or ceilings, or damaged wiring, take longer. So can problems that point to a bigger issue, like an overloaded service or a panel that needs replacing.

Older homes: problems we see often

Two-prong outlets with no ground. These can be protected with a GFCI or given a new grounded circuit.

Aluminum branch wiring in some homes built from the mid-1960s to the early 1970s. The connections need special devices or repair methods.

Backstabbed outlets. Push-in connections that loosen over time and cause dead or warm outlets.

Zinsco and Federal Pacific panels whose breakers may not trip.

Troubleshooting FAQ

Why does my breaker keep tripping?

Usually the circuit is overloaded, meaning too many things are running on it. It can also be a short or ground fault in a device or the wiring, or a worn breaker. If it trips again right after you reset it, leave it off and call.

Why did half the outlets in a room stop working?

The most common cause is a tripped GFCI somewhere upstream, often in a bathroom, the garage or outside. Check and reset those first. If that doesn't do it, there's likely a loose connection at an outlet in the chain.

Is a warm outlet dangerous?

Yes. A warm outlet or switch plate usually means a loose or overheating connection. Unplug what's on it, turn off the breaker, and have it checked.

Why do my lights dim when the A/C turns on?

A brief dip when a big motor starts can be normal. Noticeable dimming across the house, or lights that get brighter as well, can point to a loose connection or an overloaded service and should be checked.

Can I replace a breaker myself?

We don't recommend it. Working inside a panel means live service conductors even with the main off. A breaker that trips a lot is usually a symptom, not the problem.

Andre was professional, friendly, and easy to work with. He did a great job installing my EV charger and made the whole process simple and hassle-free.

I can't say enough good things about Sagan Electric. Andrey installed a Level 2 EV charger at my home in Sacramento and got the job done promptly and professionally. The work looks clean and neat, and the charger has worked perfectly from day one. What really stood out was their integrity. My original quote had expired by the time I was ready to move forward, and they honored it anyway without any hassle. They're also helping me through the SMUD rebate process, which made the whole project feel much less overwhelming. It's clear they care about their customers, not just the job.

Daniel’s team was super efficient with how they handled our job. Gave us a date, showed up on time and did what they said they would. Passed the inspection easy peasy.

Great service. Everyone was polite and responded quickly. Alex and Adam did a great job of explaining and installing the system. Will use again if I ever need a new charger.

This company was amazing! When I called, they answered, and tried to go over trouble shooting with me on the phone. When we were not able to fix the issue over the hone, they came out THE SAME DAY! Not only that, they helped me determine it must be the SMUD box and helped me call SMUD to get them out the SAME DAY too! 10/10
