"These guys came out and worked in the dead of cold in the winter in an old barn and got the job done. It was a good value for the price point. They aren't the cheapest but you wouldn't want that with a professional electrician. John has a good crew of people working with him and they'll get the job done. This was a 100 amp to 200 amp upgrade with a sub panel and electric car charger install."

"Guys were nice enough but it took them 3 days to "trouble shoot", claiming they took out and looked at all the outlets day one but couldn't find the issue and then had to come back a 2nd day and claimed they would need to cut a hole in my wall and then came back a 3rd day and found that it was an outlet issue. I couldn't get an explanation as to why it took 3 days to figure out this issue when they checked the outlets day 1. I had to pay over $1000 for work because they couldn't figure out the issue. I understand it can be hard to identify but to take out all the outlets on day one and then find the resolution was in the outlet 2 days later is terrible."

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.
