"52-YEAR BUSINESS!!! Jack Vardiman is the TOP electrician to effectively fix/set up your essential electrical systems. Checked Angie's List and selected JVEC Inc. in Brea. Jaclyn provided outstanding customer service and immediately set up an appointment. Jack's knowledge is encyclopedic; his skill is utmost; and his actions are meticulous. He instantly recognized an older GE circuit panel and efficiently replaced the damaged breaker with the appropriate part. Furthermore, the repair fee was very reasonable."

"Electricity was needed for a new control panel for my backyard sprinklers, and I needed a couple of light fixtures replaced in my house. The gentleman showed up on-time and quickly took care of everything in three hours, which included making a run to the hardware store for a part. The price was very reasonable since I used the promotion on Angie's List. Moving forward, they will be the first people I call for electrical work."

"I recently hired Mazen from Smart Electrical Solutions for a multi-stage project at my home, and I couldn't be more impressed with the results. The project was complex: a full electrical panel upgrade, a complete layout of recessed lighting, and some tricky troubleshooting of older circuits that had been giving me trouble for years. Mazen handled the panel upgrade with incredible precision. The wiring is remarkably clean and organized, and he took the time to clearly label every single breaker—something my previous electrician overlooked."

"Excellent! Haik and his crew had the unfortunate task of correcting an illegal job done by another electrician. Haik and his crew immediately came to work on our condo. They were courteous, punctual, and very professional. The work was inspected, as required by law, with no citations. As a last minute request, they also upgraded 3 of our outlets and replaced a light switch without changing the amount to our original contract. Their quote was competitive and I felt good working with an honest company. What Haik said they would do was promptly, efficiently, and correctly accomplished. A definite gold star and will not hesitate in calling him if any electrical work needs to be done."

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