"On time. Under budget. Quick to respond. Courteous. Conscientious. Knows what he's doing. Took the time to vacuum up after completion. Everything works. Came up with less costly options. Took notes when we initially spoke and knew exactly what to do when he arrived. Just an "honest-a-goodness" hard working person whom I'd highly recommend."

"The solar company I chose was one of the worst choices I have ever made. Vision Solar went Bankrupt and I had no one to help me when my system went down. I call numerous solar companies and no one would help me. Then I found Phase Out Electric it was an immediate yes after I told them what was going on. My inverter was bad and still under guarantee and they took care of getting it for me. I was kept well informed on what was happening. I will use them again if I have any more problems."

"Juan contacted me and was able to come the next morning. Within 5 minutes, he diagnosed the outlet and circuit and found the issue was a bad circuit. He also explained the current wiring and that two other circuits could be added to the panel box to take the load off a couple other circuits. In less than 30 minutes, he replaced the bad circuit as well as installing the 2 new circuits I requested since he was already here. My dryer is up and running! Juan is an absolute professional with his knowledge and expertise and got the job and more done quickly. If I need future electrical services, he’s my go-to guy."

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.
