Two things stack on top of each other in Commerce City. First, the housing age: with a median build year around 2004, a large share of these doors have never had a spring replacement, which puts a big cluster of houses into failure range at roughly the same time. Second, the climate - this whole service area sits in a severe cold band, and cold makes steel springs more brittle and openers' lubricants stiffer, so failures tend to cluster in the coldest stretches of winter rather than spreading evenly through the year.
At a median household income of $106,756 in Commerce City, most owners here are choosing between a full opener replacement and a targeted repair, not stretching for either - which is part of why we try to diagnose precisely rather than default to swapping the whole unit. The fix that matches the actual fault, not the bigger sale, tends to be the one that holds up.
