Because the climate band here is mild with only occasional freeze, the seasonal shift on an older door is less dramatic than in colder regions, but it's not nothing. Cold mornings a few times a winter are usually when a weak spring finally lets go, because the steel is marginally less forgiving when it's cold and the door gets lifted hard and fast on a rushed morning.
In the wetter months, it's the bottom seal and the bracket rust mentioned earlier that act up first - a door that drags or won't seal flush at the bottom is often just a swollen or torn weatherstrip, not a structural problem. Replacing that seal is one of the cheapest things you can do on an older door and it's the first thing to check before assuming a track or panel issue.
Summer brings the opposite complaint: openers that worked fine all year start chattering or running rough as grease inside older gear-drive units thins out in the heat. On a door this age, that's a sign to service the opener now rather than wait for it to fail on a 100-degree afternoon.
