Most of the houses we get called to in this service area went up between 1962 and 2005, with the bulk of that stock dating to the 1980s and 90s. That matters for openers because a chain-drive or belt-drive unit installed when a house was built, or swapped in during a remodel twenty years ago, is now past the age where parts wear evenly. Nylon drive gears get brittle, gears strip, and circuit boards that were fine for a decade start losing contact points from thermal cycling.
The climate here is cold-moderate, not brutal, but it's enough. Garages in this area aren't heated, and openers mounted to an unfinished ceiling see real swings - cold nights, warmer afternoons, damp air off and on through fall and winter. That cycling is hard on lubricant in the gear housing and on solder joints inside the logic board, more than heat alone would be. A opener that's fine in July can start acting up in November because the grease has stiffened and the board is drawing more current than it should to compensate.
We see this pattern across the whole area we cover, not just one neighborhood - it tracks with the age of the housing stock, not with a particular street or subdivision.
