"I'm very happy with the electric service change Woodward Electric did at my 80-year-old house. They replaced the electric panel, riser, and all the old wiring in the walls. Plus, Taylor Woodward is great to work with."

"As usual with Garafano Electric, everything went fine -- way more than fine, actually. We have used them for years on various upgrades to our 1920's mediterranean home. William, the owner, is great about explaining our options and always finds the best and most efficient way to work within the confines of an older two-story duplex on a sloped lot that has serious access issues. Pricing is fair, they have never failed to show up on the appointed day, and on time, and complete the job as agreed. They have never disappointed for over 20 years, and I recommend them without hesitation!"

"Perfect and smooth journey, Jorge came pre instillation to check the electrical panel and where the the charger was going to be installed and after the review he text me the cost of parts and installation, after I received the charger he came on time and the job was completed. I was updated by text messages throughout the process. In the future if I need any electrical work I definitely use JK Flores Enterprise."

"Ramon is now my go-to electrician I will call if I need any electrical work done. My partner and I are first time homebuyers and the home we got desperately needed an electrical panel upgrade. I found Ramon who provided fair prices and he also helped us set up our ring cameras and ceilings lights as part of the package, which reallly helped us out! The work he and his team done is clean, professional, and fantastic. He found outdated and exposed wiring and was able to fix that for us as well, so now our home electrical is brand new and SAFE. He’s nearby and it’s great to know a professional we can call anytime we need electrical work done."

"We’re so happy we were recommened Honeybee Electirc. Hector upgraded our electrical panel and also installed the connector for an EV charging station. The whole job went really smoothly from start to finish. Everything passed Edison inspection with no problems, which gave us a lot of peace of mind. He was friendly, professional, and just really easy to work with. What we appreciated most was that he didn’t just do the panel upgrade and leave, he also took the time to help organize and clean up our electrical system overall, which was above and beyond what we expected. It’s hard to find someone who does great work and is also kind and personable, but he really checked all the boxes. We’re very happy with the work and would definitely hire him again and recommend him to others."

"I had half of my house and the entire backyard on one breaker - there was an add-n to the house in the 70s and apparently whoever did the add-on decided it should just all go on one breaker. This breaker finally got a short in it and I needed re-wiring. I had several people come by to give me bids, but Emin was the only one who presented me options besides re-wiring the whole house. He and Osman were here for 3 days, and untangled the mess that was the wiring, and even added a 240 outlet for quick charging of my electric car. They were efficient, friendly, and very professional. It was a pleasure working with them, and I recommend them HIGHLY."

"Could not be any happier! Very nice and professional and his customer service cant be beat. This is a father and son business. My first time using him and I would give him 1000-stars. He was prompt, explained everything and I found his prices to be good and fair. They spent 6+ hours installing my generator to the house electrical panel and job was clean, nicely labeled and we are ready for the next SCE shut down. The quality of the products used was outstanding. I would highly recommend his services to anybody needing electrical work. When he left the job site, it was absolutely immaculate and cleaned to perfection.. They take PRIDE in their business and it shows."

"We are very pleased with the quality of the work. None of our lighting, pool equipment or outdoor electrical was working properly and Fairway Electric identified the problem immediately. After running a new line and rewiring existing outlets, we now have power to the entire backyard and it is much safer now."

FAQs for electrical wiring or panel upgrade projects in Simi 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.
