Had three calls before noon where weak dual caps and pitted contactors were causing no-cools after last night’s thunderstorm. Anyone else seeing this spike, and are you pushing surge protection and spring coil cleanings to cut repeat service?
Seeing the same — ‘weak dual caps’ and ‘pitted contactors’ popping up like mushrooms after rain; we’re swapping to 440V duals, installing a 2-pole SPD at the disconnect, and torque-checking lugs/ground on storm calls. Surge protection cuts repeat visits but lightning still wins sometimes. You getting control board casualties too or mostly contactors?
We’ve been adding a 5‑minute anti‑short‑cycle delay at the condenser to keep post‑storm brownouts from machine‑gunning the contactor — doesn’t save a direct hit, but it’s cut repeats; @scarlett5298 you seeing board casualties too?
We’ve been recommending seasonal maintenance a lot lately, especially after storms. It’s like a good spring cleaning for the system. What do you think about adding a surge protector for peace of mind? @tommill said they’ve had some success with delayed payoffs.
