Should I install a whole-home surge protector?

Yes, a whole-home surge protector is a wise investment. It installs at your main panel and protects all the wiring and appliances in your home from voltage spikes caused by lightning strikes or utility grid fluctuations. Unlike power strip surge protectors, it guards hard-wired appliances like your HVAC, refrigerator, and washer. Installation by a licensed electrician costs $300 to $600.

Why It Matters

A single power surge can damage expensive electronics and appliances. Whole-home protection costs a fraction of replacing your HVAC system or entertainment center.
