Princeton sits in a moderate-heat climate band, which matters more for openers than for the doors themselves. Summer heat cycles the steel track and the spring coil daily, and on a 2012-era door that's already worked through most of its factory life, the failure that shows up first is usually the opener - a sensor drifting out of alignment, or a logic board finally giving out after years of heat soak in an attached garage. Because the housing stock here is younger than in older parts of the service area, we see fewer sagging wood-panel doors and rotted jambs, and more of the wear that comes from a door that's simply been cycled a few thousand times a year for a decade or more: worn rollers, a spring that's lost tension, a cable starting to fray at the drum. With 6,809 households in town, the call volume here doesn't run as heavy as it does in the larger cities on the route, but the failure pattern is consistent enough that we can usually guess what we're walking into before we open the truck.
