The climate band here is mild temperate, which is kinder to opener electronics than the hard freezes some parts of the country deal with - no circuit boards cracking from a deep cold snap, no belts going brittle overnight. That's the good news, and it's genuinely true for every house in the area regardless of age.
The bigger driver of opener failure here is simply age stacked on age. With a median build year of 1983, a lot of these houses are on their second or even third opener, and each swap inherited whatever rail and bracket setup the first one used. Gears strip, capacitors in the logic board fail, and chain drives stretch - all of that happens on a timeline, not because of a single event, and a unit installed new in the 1980s or 1990s is well past any reasonable service life by now.
We also see openers here that were replaced once already but on mismatched hardware - a newer head unit bolted to an original rail it wasn't designed for. That combination works until it doesn't, usually showing up as a door that reverses randomly or won't fully close.
