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 Dartmouth in a single short visit.
“Called at 11pm when half the house went dark and an outlet was making a noise I'd never heard before. Someone was at the door in under an hour and had it isolated before midnight.”
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
“Garage had one outlet and a light on the house circuit. Now it has a sub-panel and I can actually use my tools.”
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 Dartmouth home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
