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 Ludlow 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.”
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
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 Ludlow home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
