Most of the houses in this service area went up between 1988 and 2014, with the bulk of that building happening in the 2000s. That matters more than it sounds like it should. An opener has a working life, and so does a torsion spring, and when a whole neighborhood gets built inside a ten-year window, a lot of that original hardware starts failing inside a similar window too.
Across the 23 named subdivisions that make up this area, the housing stock skews so heavily to the 2000s that we see failures cluster by street and by build phase rather than spread evenly year to year. A block that went up in 2003 tends to call about the same problems around the same time.
Heat adds to it. This area sits in a moderate-heat climate band, and a garage that isn't conditioned runs hotter than the rest of the house for months at a time. That heat dries out the grease on steel rollers, stiffens cables, and - on openers from that original construction wave - cracks the nylon gear inside the motor housing. None of that is dramatic on its own. It just means doors built in the same era tend to wear out in the same way, at the same time, for the same reasons.
