Across the service area, most houses were built between 1975 and 2013, with the typical home dating to 2000, which puts a lot of original chain-drive openers now in their second or third decade of use. A chain-drive unit from that era was built to last 15 to 20 years under normal cycling, and a lot of them are past that mark right now, straining a gear set that was never meant to run this long. The 17 named areas we cover share that same stock almost everywhere, so the failure pattern looks the same house to house: worn drive gears, a logic board that's seen two decades of power surges, and a remote system that predates rolling codes.
The climate here sits in a mild band with occasional freeze, which isn't severe, but it's enough. A hard freeze a few times a winter stiffens grease in an old gear housing and can throw off a photo-eye alignment that was already marginal. None of that destroys an opener overnight. It wears down the motor capacitor and the drive system a little at a time until a unit that limped along for years finally won't lift the door at all, usually on the coldest morning of the stretch.
