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 Shirley in a single short visit.
“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.”
“They found a loose neutral that had been slowly cooking our appliances for years. Nobody else even looked for it.”
“Breaker had been tripping for months and two other companies just replaced parts. OSB traced it to a backstabbed outlet behind a bookcase in twenty minutes.”
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 Shirley home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
