Bloomfield counts about 2,596 households, which is a town-sized service area, not a city sprawl - enough calls to see patterns, not so many that every door looks different. Most of those houses went up around 1985, give or take a few years on either side, so a huge share of the garage doors still running out here came with the torsion hardware that was standard for that build era. That hardware is thirty-plus years old now. Steel fatigues on a fixed number of open-close cycles, not on a calendar, and a spring wound in 1985 has usually hit that number regardless of how well the door was maintained.
The cold is the other half of it. This stretch of New Mexico sits in a cold-severe climate band, and steel springs lose a measurable amount of tensile give in hard freezes. A spring that was already near the end of its cycle life tends to pick a cold January morning to finally let go, because the metal is stiffer and the last few coils give out under load instead of gradually loosening. It's not bad luck - it's an old spring meeting its worst working conditions on the same day.
