Houses built in the same stretch of years don't all get the same hardware. Builders in the late 90s used a handful of different door and opener brands depending on who was supplying the subdivision, so two houses a block apart in Sherwood can need different spring sizes or different sensor harnesses. We size on site rather than guess from the build year alone.
Sherwood sits in the same mild, occasional-freeze climate band as the rest of the area we cover, so you're not dealing with hard winter cold snapping springs the way colder regions see. What you do get, over two decades, is slow corrosion on cable ends and roller bores from condensation cycling through an unheated garage - less dramatic than a cold-weather snap, but it adds up the same.
One more thing worth saying plainly: if an opener's circuit board is discontinued and the part can't be sourced in a reasonable window, we'll tell you to replace rather than wait. Chasing a part that doesn't exist anymore isn't a service to you, it's a delay.
