"Today I had Higher Power Electrical come out to install a Level 2 EV charger at my home, and I couldn’t be more satisfied with the experience. From start to finish, the electrician was incredibly respectful, easygoing, and professional. He took the time to walk me through the entire process, making sure I understood each step of the installation. I really appreciated how clearly he explained everything—from the panel upgrades to the placement of the new breaker. It wasn’t just a quick install and go; he made sure I was fully informed and comfortable with the work being done. He also showed me the new NEMA 14-50 outlet and explained that it was installed to meet the proper approval and safety standards, which gave me great peace of mind. The attention to detail and clear communication throughout made the experience smooth."

"Wilson Electric is very honest, reliable and responsive and reasonable. What a pleasure it was to deal with them.My rental had no heating. When I purchased it I was told it had heating in the ceiling and it didn't work. I also thought I would need to upgrade my circuit breaker box. Steve came out, checked it out and said all I needed was thermostats and two circuit breakers as the original ones for the bedrooms had been used for the washer and dryer hookups."

"I got a few estimates to get more power out to my studio. Everyone quoted me about 4K to upgrade my panel and get dedicated line out to my studion. These guys were to only ones that looked for a better/more economical solution. I sent a pic of my panel and he remembered that I upgraded my kitchen a while back but noticed that my electric stove had it's own dedicated line. He asked me, did you convert to gas when you remodeled? I said yes and he said, great, we take the line that was dedicated to the stove and we use that. It saved me $1500 and it worked perfectly. I would absolutely hire again!"

FAQs for electrical wiring or panel upgrade projects in Corona, 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.
