Most of the houses we get called to in Chicopee went up between 1938 and 1989, with a lot of that stock clustered in the 1960s and 70s across the neighborhoods that make up this area. Doors from that era were sized and sprung for lighter panel material than what's sold today, and a lot of them are still running on the torsion spring that came with the house. Springs are rated in cycles, not years, but cold makes the metal more brittle and less forgiving on every open and close. Chicopee sits in a severe cold climate band, and that matters more than people think. Steel contracts in low temperatures, lubricant thickens, and a spring that's already near the end of its rated life is more likely to snap on a 10-degree morning than a mild one in July. That's why we see a real jump in torsion spring calls once the first hard cold sets in. It isn't bad luck. It's a 50-plus-year-old spring meeting its worst working conditions on the same day. Add in original rollers and hinges that were never upgraded, and you get a door that binds, drags, or drops all at once instead of failing gradually where you'd notice it coming.
