Most of the housing stock across this service area went up between 1990 and 2012, with the median build year sitting around 2001. Across the eleven communities this page covers, that's the same story: builder-grade torsion springs installed when the house was framed, rated for somewhere around 10,000 cycles, and nobody has touched them since. A spring installed in 2001 that opens the door four times a day has quietly used up its cycle count sometime in the last several years. That's why the call always comes as an emergency - there's no slow leak, no warning squeak that builds for months. The spring holds tension until it doesn't, and then the door is dead weight on two cables.
The climate here adds a second failure path. Winters aren't brutal, but they're cold enough, often enough, that grease on rollers and tracks stiffens overnight, and the metal in tracks and cables contracts slightly. On a door already running near the end of its spring life, that extra resistance is sometimes the last straw - the opener motor strains against a stiff track, strips a gear, or the cable finally jumps its drum. None of this is dramatic weather. It's ordinary cold acting on hardware that was never meant to last this many winters.
