Van Alstyne's housing stock centers on 2005, newer than a lot of the area around it. That matters for openers because most of these houses have never had the opener swapped - it's still the unit the builder put in, now pushing past the fifteen-year mark where belt and chain drives start losing teeth, circuit boards start drifting on voltage, and the original safety sensors get knocked out of alignment from years of nobody touching them. A door that's gone from quiet to grinding, or that reverses halfway up for no reason, is usually that original drivetrain finally giving out, not a new problem. We also see more sensor and logic board failures than spring failures out here, because the doors themselves are younger than the climate band would otherwise suggest - cold winters and swings in humidity are harder on electronics and lubrication than on the steel panels themselves.
