"We had 3 electricians give us a quote for a pretty big job, 40 recessed ceiling lights, a new panel, and electricity to the detached garage . Jason Kenny gave us slightly the lowest quote, but what impressed us is that during the consultation he walked through our house and was the only one who looked at the walls from a how to get this project done perspective, how to go about completing the required work. He gave us the impression he was gonna get it done! The work took a good 3 days and was excellent. Along with his assistant Jason worked quickly. He was easy to communicate with and good at explaining things. We felt comfortable giving him our keys in case we would be out on one of the days he worked. Highly recommend! Great experience."

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.
