Whole-Home Surge Protection

One bad power spike can take out your HVAC board, EV charger, TVs, and appliances in an instant. A panel-mounted surge protector stands guard over your entire home, around the clock.

What is whole-home surge protection?

A whole-house surge protective device (SPD) installs directly in your electrical panel, where it monitors every circuit in the home at once. If a voltage spike hits your service, from a lightning strike, a utility grid event, or your own HVAC and appliances cycling on and off, the device diverts the excess energy to ground before it can reach anything plugged in or hardwired.

It's a different kind of protection than the power strips most people already own. Those only protect whatever is plugged into them, and they wear out silently over time. A panel-mounted SPD covers outlets, lighting circuits, and hardwired equipment like your furnace, water heater, and EV charger, all from one device.

Why it matters more than ever

Homes carry more sensitive electronics than they did even ten years ago: smart thermostats, home theater systems, computers, and increasingly EV chargers and solar equipment. Each of these has circuit boards that can be damaged or degraded by surges most homeowners never notice happening. Over time, unprotected surges shorten the life of expensive equipment even without a single dramatic failure.

What our installation includes

  • Panel evaluation: We check your panel's condition and available space before recommending a device.
  • Type 2 surge protective device: Installed at the main panel (and sub-panel, if you have one) to protect the whole home.
  • Proper breaker & grounding: Connected on a dedicated breaker with a solid ground path, per manufacturer and code requirements.
  • Status indicator: Most devices include an LED so you know at a glance that protection is active. Many also have a built-in buzzer that sounds when the device has absorbed enough surges that it's time for a replacement.
  • Permit & inspection: Pulled and scheduled when required, so the install is documented and code-compliant.

A smart add-on to other panel work

If you're already having your panel upgraded, a service change done, or an EV charger or hot tub circuit added, a whole-home surge protector is one of the most cost-effective upgrades to add at the same time, since the panel is already open, installation only adds a small amount of labor.
