If your opener out here is original to a house built in or around 1991, it's getting close to or past the age where the motor, gears, and logic board start showing wear together rather than one at a time. Watch for a unit that runs longer than it used to before the door starts moving, a light that flickers on activation, or a door that reverses partway up for no clear reason.
Because the housing stock here is newer than most of what we cover, we see fewer doors that need a full hardware rebuild alongside the opener swap. What we do see is openers original to the house reaching the end of their working life around the same time, since they all went in within a few years of each other when the neighborhood was built out. If yours is chain-driven and louder than it used to be, that's usually gear wear, not a sign the whole door needs replacing.
