"I am updating my rating for CA Electrical (Unfortunately Angi will not allow me to edit, so I am posting this as a new review). After posting my original review I was contacted by CA Electrical. The supervisor assured me that my experience was not their normal practice and that they normally made sure to call if there was a change of plans. I felt that they were earnest in trying to make things right, so I agreed to give them another chance. I ultimately decided to select them for my project to replace sub panel and install outlets. The crew was excellent and professional. They showed up on time, were professional and friendly, took extra care to ensure work spaces were left clean. Their workmanship was excellent and they did a great job of cleaning up some messy electrical wiring that had been there before. As an electrical engineer, I also appreciated the crews knowledge of code and ability to explain the technical side of the installation. I would use them again."

"Ray gave me a call while I was in the process of finding an electrician to troubleshoot a wiring problem at our office space. I told him that some of the outlets were working while some of them were temperamental. Ray came to the office with a sense of urgency, and not only checked out the electrical panel, but looked at every individual outlet that was not working. He explained what the problem was in great detail, and was very confident that he could fix the problem, and scheduled for two of his workers to come out the following day to tackle the issue. They were able to fix it in about an hour, and everything is working perfectly now. I immediately asked for a way to give a review, so here I am right now. 10/10!!!"

"Stephen was knowledgeable about the Code requirements for Oakland (not all of the electricians who quoted on the job were) and flexible in working through the equipment needs (a panel and a subpanel). He and his crew (Jeff and Tom) were quick, clean and efficient in the installation and the price for the work was fair. I definitely would hire them again if I need more electrical work."

"I loved working with Dalcon. From the estimate and working with Zachary to the excellent wiring by Reggie and Christian, they are very professional. I had an ancient main panel replace with a newer larger main panel. In addition they added 6 new circuits. The main panel wiring was so well done that the inspector said he had not seen work that good in years. Dalcon is expensive but I believe that it was well worth it."

"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!"

"I purchased a small wine cooler from Wayfair and needed installation. Before that could be done, I need electrical to the cabinet where the wine cooler would go. Ivan did the whole job for me and it looks great! I can hardly wait to use it! Ivan and his assistant were diligent and cleaned up the mess that gets made when doing work of this kind. He communicated everything that I needed to know and was very professional. I will definitely use him again."

FAQs for electrical wiring or panel upgrade projects in Castro Valley, 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.
