Farmington sits in a severe cold climate band, and that matters more for cables than people expect. Galvanized aircraft cable loses flexibility as temperatures drop, and repeated freeze-thaw swings through the winter work-harden the strands at the pressure points - where the cable wraps the drum and where it seats in the bottom bracket. That's exactly where you'll find the fraying.
Most houses across the service area were built between 1978 and 1993, with that same 1980s-90s stock showing up across all six communities we cover - Flora Vista, Upper Fruitland, Kirtland, Bloomfield, Aztec, and Waterflow. A cable has a working life, and a door installed in the mid-80s is carrying original or first-replacement cable that's now had three or four decades of cold-weather cycling. That's not a defect, it's just the math of age plus climate.
With 2,935 owner-occupied houses out of 6,936 households in this area, you're looking at a large pool of doors hitting that same age-and-climate wall around the same time, which is why cable calls cluster the way they do once the weather turns.
