"Ted came to my home to provide a quote for a panel upgrade and a sub-panel run to the garage. He was very knowledgeable andprofessional and spent quite some time brainstorming with me on how best to handle my project. The estimate I received from Apollo was very competitive but I ultimately decided to contract with another electrician. Overall, my experience with Apollo was fantastic and I would definitely consider Apollo again for future projects."

"I hired JC Electric (Jaime) for two projects: a panel upgrade and an EV charging installation. In both cases, Jaime was meticulous, reliable, and highly skilled, ensuring the projects were completed on time. Beyond his expertise, he is an honest and trustworthy professional. I would gladly work with him again on future projects and highly recommend his services."

"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."

"We hired Jacob for a panel upgrade and a re wire for our home. He and his team were professional and efficient! He was very communicative throughout the whole process! We were referred to him by our neighbor, and will be passing his info along to all others who inquire! If we could give him more than 5 stars, we would! Very very pleased with the work that was done!"

"I highly recommend Alfonso from Pellegrin Electric for any electrical work you need. From start to finish, he exceeded my expectations with his professionalism, attention to detail, and deep knowledge of electrical systems. I hired Alfonso for a full-house rewiring project, including installing all the electrical fixtures I purchased and upgrading my service from 100 amps to 200 amps. This was a major job, and after researching and getting quotes from multiple electricians, I ultimately chose Pellegrin Electric and I?m so glad I did. Alfonso was not only skilled and efficient, but he also took the time to explain everything clearly, ensuring I understood the process and what to expect. His workmanship was meticulous, and he left my home cleaner than when he arrived, showing a level of care and respect that is hard to find. If you?re looking for an electrician who is reliable, highly experienced, and dedicated to doing the job right the first time, look no further than Alfonso!"

FAQs for electrical wiring or panel upgrade projects in San Jose, 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.
