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 Otis in a single short visit.
“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.”
“They rewired our restaurant kitchen overnight so we never closed a single service. That mattered more than the price, honestly.”
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 Otis home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
