Whole-Home Surge Protection | Long Island

Whole-home surge protection is a device (a Type 2 surge protective device, or SPD) installed at your main electrical panel that shields every circuit in your home from damaging voltage spikes. Unlike a power strip that protects one outlet, it stops surges from utility switching, lightning, and large appliances cycling on and off before they reach your electronics, HVAC, EV charger, and appliances. Current electrical code now requires whole-home surge protection on Long Island panel and service upgrades, and it's one of the highest-value protections you can add — typically $300–$700 installed. We install it as part of any panel upgrade or as a standalone visit.

Why it matters for Long Island homeowners

Modern homes are full of sensitive electronics — smart panels, EV chargers, heat pumps, TVs, computers — that are expensive to replace and vulnerable to surges. Long Island's overhead distribution and summer storms make surges common. A single whole-home SPD protects the entire house for a fraction of the cost of one ruined appliance.

Frequently Asked Questions

Is whole-home surge protection worth it?

Yes. For $300–$700 it protects every appliance and device in your home from surges that can cost far more to replace. It's now required on Long Island panel upgrades.

Do I still need power strips with whole-home surge protection?

Point-of-use surge strips add a second layer for sensitive electronics, but the panel-level device does the heavy lifting by stopping surges at the source.
