Most of the garage doors we open up in Vinings date to construction in the 1990s, not the 1950s-through-70s range that covers most of the service area. That means you're less likely to find an old side-mounted torsion setup and more likely to find a standard center-mounted torsion spring over a steel sectional door with a chain-drive or screw-drive opener from that era.
The common failure we see on these newer doors is wear, not obsolescence: a torsion spring that's done its 10,000 cycles, a bottom roller that's worn its track groove oval, or a safety sensor that's drifted out of alignment after years of small bumps. None of that is dramatic, but it adds up to a door that groans, reverses on its own, or won't close all the way.
The cold-moderate climate band this area sits in also plays a role - temperature swings through the year stiffen lubricant in springs and hinges that haven't been serviced, which shows up as a door that's noticeably harder to lift on a cold morning than it was in August.
