He always responds quickly and is flexible with setting up appointments. Exceptionally neat and clean work! Very professional and a pleasure to talk to. Ben will continue to be my contact for anything electrical!"

"Fred was very communicative and flexible in helping me, my landlord and my fellow tenants work out the solution for adding a new 220V circuit and isolating some of my circuitry from the panel in my neighboring tenants office!. After understanding a relatively complex set of issues quickly he provided a fair estimate and proceeded with the job to fit the schedule of my neighbors to avoid interrupting their service by working on a Saturday. Fred arrived fully equipped and was able to finish the job in one day to my specifications and well done! Amber Electric Service is my new go to electrician. I am very pleased!"

"Don't hesitate to hire Emrom Electric however complicated a job you are considering. There is no construction or design problem too difficult or detailed for Emrom to solve! We are more than happy with the new mast, wires, fixtures and switches installed by Emrom with economy and skill. The Emrom people cheerfully worked under the house and in our tiny attic to accomplish some very challenging parts of the job. The whole project was truly an upgrade in every sense of the word. Our house is over 75 years old and now has the safety and comfort of a new electrical system without in any way diminishing its charm. Emrom completed the job with great care and a minimum of disruption. We highly recommend their work."

"Edgar is very detailed, respectful, professional with very good customer service! He showed up on time and completed the electric panel change sooner than expected! I have already referred him to my cross the street neighbor, Diane. Hopefully she will reach out soon for an estimate to change out her electrical panel too. Thank you ð ð"

"Ivan and Edgar were amazing! I originally brought them on board for an EV charging outlet to be installed in my detached garage. After a quick assessment, we learned I would need to have a new electrical panel installed and a new line run under the home to the garage. The work was done quickly and flawlessly. Their price was also very competitive to many of the quotes I was provided from other teams. On top of that, Ivan and Edgar were extremely professional and friendly. I plan to also hire them for a recessed lighting project in my living room, which I learned is their specialty. Thank you IC Electric for an amazing instal!"

FAQs for electrical wiring or panel upgrade projects in Hercules, CA

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
