Short answer: The spring does almost all the heavy lifting every time your garage door moves, which is exactly why it is the part most likely to fail and leave you stranded. A little attention now can add years to its life and keep a sudden snap from catching you at the worst possible moment.

Why springs wear out, and the clues that come first
Garage door springs store an enormous amount of energy so your opener (or your arms) do not have to. Most homes use either a torsion spring mounted on a bar above the door or a pair of extension springs running along the tracks, and both are rated by cycles rather than years, with many standard springs designed for roughly 10,000 open-close cycles. A family that opens the door six or eight times a day can burn through that far faster than someone who parks on the street. Sunnyvale's damp morning air and coastal humidity also invite surface rust, which shortens spring life by increasing friction between the coils. The good news is that springs almost always warn you before they let go: a door that suddenly feels heavy, jerks or hesitates on the way up, hangs crooked, or makes a loud bang for no reason is telling you the spring is stressed. A visible gap in an otherwise tight torsion coil is the clearest red flag of all.
Simple habits that stretch spring life
Twice a year, run a quick balance test: pull the opener's release cord to disconnect it, then lift the door by hand to about waist height and let go. A healthy, properly tensioned door should hold roughly in place. If it slams down or shoots up, the spring is out of balance and working against itself, which accelerates wear. Keep the coils clean and lightly coated with a garage-door-rated lithium or silicone lubricant two or three times a year, and wipe off grime before you re-apply. Avoid using WD-40 as a lubricant here, because it cleans and displaces rather than protecting the metal long-term. Just as important, never let the opener muscle a struggling door open again and again. Each forced cycle stresses an already-tired spring and can turn a slow decline into an abrupt break.
Know where DIY ends
Cleaning and light lubrication are homeowner-friendly, but a loaded spring is under extreme tension and is not a part to adjust, tighten, or replace yourself. A slipped winding bar or a coil that lets go can cause serious injury. If your balance test fails, you spot a gap in the coil, or the door has become genuinely hard to lift, treat it as a repair to schedule rather than a chore to attempt. Spring replacement typically runs in the range of a few hundred dollars depending on the spring type and whether you replace one or both, and doing both at once is often worth it because a matched pair tends to age at the same rate.
