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 Pembroke 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.”
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
“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.”
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 Pembroke home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
