Most of the housing stock across this service area went up between 1969 and 2006, with the bulk clustered in the 1980s and 90s. That's not a random detail - it's the whole reason maintenance calls here look different from a brand-new subdivision. A door and opener installed in, say, 1987 has been cycling for close to four decades. Springs are rated in cycles, not years, and a door used twice a day for that long is hitting or past the end of that rating right now, whether or not it's ever been serviced.
Anna sits in a cold-moderate climate band, which means the metal in your track, springs, and hinges isn't sitting at one steady temperature all year. It contracts in a cold snap and expands again a few weeks later. Lubricant that was fine in October gets stiff in January, rollers bind slightly, and the opener's motor works harder to push through resistance it wasn't designed to fight. None of that shows up as a dramatic failure at first. It shows up as a door that's a little louder, a little slower, a little more hesitant - the kind of thing an owner lives with for months before calling anyone.
