One panel-mounted device protects every circuit, far more effective than power strips alone.
About Whole-House Surge Protection
A whole-house surge protector installs at your electrical panel and shields every circuit from voltage spikes, whether they come from the grid, lightning, or large appliances cycling on and off inside your home. It's far more effective than power strips, which only protect what's plugged into them.
With sensitive electronics, an EV charger, or a battery system in the home, a panel-mounted surge protector is inexpensive insurance against damage. Our electricians install it directly at the service panel for whole-home coverage.
What it protects
- HVAC, appliances, and motors
- EV chargers and battery systems
- TVs, computers, and smart-home devices
- LED lighting and electronics on every circuit
Field note: the surge damage nobody attributes to surges
Lightning gets the blame, but the surge damage we actually see is quieter: a furnace control board dead after a grid switching event, garage door openers that fail young, LED fixtures flickering into early retirement, appliance electronics degrading over years of small internal spikes from the home's own motors cycling.
That's why whole-house protection at the panel changes outcomes, it clamps both the dramatic external events and the constant internal chatter. The $300–$700 device routinely outlives multiple appliances it silently saved. After any close lightning event or major grid disturbance, check the SPD's status light; absorbing a big hit is its job, and replacement after one is cheap.

If you have sensitive electronics, an EV charger, or a battery system, yes, it's inexpensive insurance against spikes.
Point-of-use surge strips add a second layer for your most sensitive electronics, but the whole-house unit at the panel is the primary, most effective protection.
Most last several years; many have an indicator light and should be replaced once their protection is used up, especially after a major surge.
