Anna's housing runs 1969 to 2006, with the median build year sitting at 1986, and most of the stock across the area's 14 named neighborhoods dates to the 1980s and 90s. That matters for one reason: torsion springs are rated for a number of cycles, not a number of years, and a door installed when a house was built in the mid-80s has had three to four decades to use up that rating. A lot of Anna garages are hitting that wall right now, all at once, because so many houses went up in the same narrow window.
The climate band here is cold-moderate, which means real swings between summer heat and winter cold rather than a flat year-round temperature. Steel springs and cables contract and expand with that swing, and the contraction in colder months is when a spring that's already near the end of its cycle count finally lets go. This isn't a defect in the door - it's ordinary fatigue showing up on a predictable schedule because so much of the local stock was built in the same era, under the same conditions, year after year.
So when we get a call about a door that worked fine last month and won't budge today, the first question we're asking is how old the house is, because in Anna that answer usually points straight at the spring.
