Is Whole House Surge Protection Worth It in North Carolina?
North Carolina sees dozens of thunderstorm days each year, and lightning is only one source of surges. Utility switching, nearby industrial equipment and your own HVAC compressor all send spikes through your wiring.
How a whole house surge protector works
Installed at the panel, it diverts excess voltage to ground before it reaches your circuits. Type 2 devices mount at or inside the main panel; Type 1 devices mount at the meter base.
What it protects
Everything hardwired or plugged in: HVAC equipment, refrigerators, washers, EV chargers, smart home devices, TVs and computers. Modern appliances have sensitive circuit boards that can fail from repeated small surges.
Why power strips aren't enough
Power strips protect only what's plugged into them and have limited capacity. Layering a panel-mounted unit with point-of-use protectors gives the best coverage.
Cost vs replacement
A single HVAC control board can cost more than the entire surge protection install.
