If your door is slow to open, drifts shut partway, or the opener motor runs noticeably longer than it used to, that's consistent with an original 1993 spring losing tension - not an opener problem, even though the opener is what's straining. A loud bang followed by the door refusing to lift by hand or motor is a snapped cable or spring, and at that point the door isn't safe to force open.
If you're hearing a grinding or clicking from the opener head itself, especially in cold weather, that's more likely the gear set inside a chain-drive unit this age wearing out, which is a different call than a spring job.
