Across the service area, most houses were built between 1953 and 2014, with the median landing around 1990, which puts a lot of original openers past their expected lifespan right now. An opener installed when the house went up in the late 80s or early 90s is closing in on 35 years of daily cycling. That's not a scare number - it's just how long a chain-drive motor and a set of gears last before the nylon strips or the logic board gives out.
In the 22 named areas that make up this territory, the housing stock leans hard into 1980s and 90s construction, the exact years when chain-drive openers with no rolling code security were standard equipment. Those units don't fail because they're bad products. They fail because three decades of North Texas summers have baked the capacitors and dried out the lubrication in the gear housing.
The heat band here runs moderate, not severe, so we don't see the extreme thermal swings that fry circuit boards in six months, but summer heat still shortens the life of belt drives and logic boards over the decades this stock has been standing. It's slow wear, not sudden failure - which is exactly why so many openers all seem to quit around the same age instead of at random.
