A power strip protects a lamp. A panel-mounted surge device protects the furnace board, the heat pump, the range and every circuit in the house. OSB installs whole-house surge protection across Charlton Depot in a single short visit.
“Every smart switch I bought failed because there was no neutral. They pulled neutrals in the rooms that needed it and set up the rest properly.”
“Two-prong outlets all through a 1920s house. They grounded what could be grounded and GFCI-protected the rest, then labelled everything.”
“Bought an EV and had no idea what my panel could handle. They did the load calculation, told me straight that I had room, and installed the charger two days later.”
It's one of the cheapest protective upgrades available — typically a few hundred dollars installed when there's panel space. Far less than one furnace control board.
No, it layers with them. The panel device knocks down the big hit; point-of-use strips clean up what's left for sensitive electronics.
Nothing stops a direct strike. Surge devices handle the far more common nearby strikes, utility switching and grid transients that quietly kill appliance boards.
Usually under two hours in a Charlton Depot home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
