Housing across this service area was mostly built between 1976 and 2012, with the bulk of it going up in the 1980s and 90s. That matters for openers because a huge share of the units still in service are original chain-drive or early screw-drive models from that build window, now thirty-plus years old. The gear sets in those units are plastic, and plastic gears wear out whether or not the door ever had a problem.
The climate here is the other half of it. We sit in a cold-moderate band, which means the garage swings through real freeze-thaw cycles every winter without ever being a true deep-freeze climate. That cycling is hard on circuit boards and capacitors mounted in unconditioned garages - condensation forms, corrodes contacts, and you get an opener that hums but won't engage, or a remote range that drops to a few feet.
Across the roughly 15,816 households and 12,629 owner-occupied houses in this service area, that combination - mid-80s to late-90s opener plus an unheated garage - is the single most common reason we get an opener call. It's not a defect in any one brand. It's the age of the stock and the weather doing what it does over three decades.
