"The Tech/owner was awesome. On time, polite and very knowledgeable. I had several outlets and overhead lights that suddenly stopped working. He found the problem and fixed it in less than an hour. Repair cost was very reasonable and he didn't try to push anything else on me. At 73 and 100% disabled Veteran I wasn't able to do the physical part of the job. He had to climb over storage tubs to get to the electrical panel which would have been nearly impossible for me. If you want a top notch electrician Wolf Electric is who I would recommend. No BS, polite and actually early for the appointment that was set up less than 24hrs. earlier. Also called a little earlier to check to see if it was OK !! Great job Alex and Wolf Electric !!!!!"

"Corey was terrific. He came to give the quote for new front porch poured concrete stairs, walkway, and a retaining wall with brick on the front face of the wall. The price was a little higher than other bids, but he presented the most professional ideas, demonstrated experience, and we were very confident with PVI. His crew was great, and they did a beautiful job. It was finished last November just before the weather got cold. We asked him back in the spring to trim up some of the concrete edges when were doing some landscaping and he came back out and finished it off. We are very happy with the work, and would definitely recommend."

Electrical wiring or panel upgrades FAQs

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.
