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 Thorndike in a single short visit.
“We had knob-and-tube in the attic and our insurer was getting nervous. They rewired in stages so we never lost power for more than a few hours at a time.”
“Sold our house and the buyer's inspector flagged eight electrical items. OSB fixed all of them in one visit and wrote it up so we could close on time.”
“Our panel was original to the house and completely full. OSB upgraded us to 200 amp, pulled the permit, met the inspector, and left the basement cleaner than they found it.”
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 Thorndike home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
