"3 ceiling fans and 1 ceiling light were installed in 1 day as promised. I like that they text me a day before to confirm/remind me of the upcoming appointment, and that they show up on time. They were courteous and professional. They cleaned up, patched up, and vacuum after the job. I'm pleased with the job performed and would definitely use them again for any future electrical related jobs."

"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."

"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 San Dimas, 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.
