"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!"

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"The original visit was to correct several electrical issues we had.  The electrician did an excellent job and even gave us less expensive options, which we took. We have already hired them for additional work, which was also succesfully completed.

"Van Sant Electrical added a 240-volt circuit and wiring through our attic for our new backyard spa. We couldn't be happier with the result! The owner, Austin Van Sant, showed up on time for an estimate and answered all our questions and concerns. He and his team came to our home the next day and completed the work on schedule with a "can-do" attitude. When the work was near completion, they had us fill the spa with water and then tested all of the spa equipment and connections. And they made sure we knew how to operate the breakers and outlets safely. Their work got an A+ from the City's permit inspector. Like all home improvement projects, this one had unexpected challenges, including additional requests from my wife to replace a broken outdoor socket and add a 110-volt outlet next to the spa panel. They were able to expertly deal with every one of them, sometimes quite creatively. All the external conduits were painted to match our house stucco. When they finished the job, everything fit together neatly and looked professionally done - - - this was important to us and much appreciated. We are extremely glad we found this local company and chose them to make our spa dream come true! We will certainly use Van Sant Electrical again for any future electrical project!"

"It went great, Had excellent service and was also appreciative of a weekend response. My work hours don't allow for typical 8-5 service calls. The only rating I listed as low was responsiveness and only because I could never get ahold of them again to come back for additional repair work. That could be a fluke, but never got any further estimates or calls to continue with additional work despite some follow up e-mail and phone calls."

FAQs for electrical wiring or panel upgrade projects in Green-Valley-Lake, 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.
