Here's what most homeowners don't realize about garage door springs: your door likely relies on one of two completely different spring systems, and confusing them can lead to costly mistakes. The two main types are torsion springs and extension springs. Each has a different lifespan, repair cost, and failure pattern. Knowing which one you have helps you understand when replacement becomes necessary and prevents unsafe DIY attempts.
Torsion springs sit horizontally above your garage door opening, mounted on a metal shaft. They work by twisting and storing mechanical energy as your door closes, then releasing that energy to help lift the door open. This design is engineered for balance and control.
Most modern homes built in the last 20 years use torsion springs. They're more durable than their counterparts and typically last 7 to 9 years with regular use. A standard residential torsion spring can handle roughly 10,000 to 20,000 cycles (a cycle is one complete open-and-close). If your family opens and closes the garage door four times daily, that translates to about seven years of service.
Torsion springs are safer than extension springs because they're under less overall tension and contained within a shaft. When they fail, they tend to break more predictably. The real danger comes from attempting repairs yourself. The tension stored in these springs is powerful enough to cause serious injury or death.
Extension springs run vertically along both sides of your door opening, stretching and contracting as the door moves up and down. They store energy through extension rather than torsion, which is why they're called extension springs.
Homes built before 2000 often use extension springs. They're less expensive upfront than torsion systems, but they don't last as long. Most extension springs need replacement every 5 to 7 years. They're also more prone to visible wear since they're exposed on the sides of your opening.
Safety cables run through extension springs for a reason: when they snap, the spring can whip across your garage with tremendous force. If a cable weren't there to catch it, the spring could injure someone nearby or damage your vehicle.

Look above your garage door opening. If you see a horizontal coil wound tightly around a metal shaft, you have torsion springs. This shaft usually runs the full width of your door opening.
If you see two springs running vertically along the sides of your opening, stretching and contracting as you open and close the door manually, those are extension springs. Extension springs sit on tracks or cables.

A snapped spring is one of the most common garage door emergencies. You'll notice your door feels heavier when opening, or it won't open at all. The door may tilt to one side or move unevenly. Never force a stuck door open when a spring is broken. The opener can fail, or the door itself may fall.

How long do garage door springs last? Torsion springs typically last 7 to 9 years, while extension springs last 5 to 7 years. Lifespan depends on use frequency, maintenance, and climate. Springs in humid areas may wear faster due to rust.
Can I replace just one spring? No. Both springs should be replaced together, even if only one has failed. They wear at similar rates, and replacing one creates imbalance, causing premature failure of the other spring.
What does a snapped spring sound like? Most homeowners report a loud bang or crack, similar to a gunshot. The door may also become suddenly heavy or refuse to open. Never force it. Call a professional immediately.
Is it safe to open my door if a spring is broken? No. A broken spring removes the counterbalance system. Your opener may burn out trying to lift the full weight of the door, and the door could fall unexpectedly.
How much does spring replacement cost in Murfreesboro? Torsion spring replacement averages $200 to $300 per spring, including labor. Extension springs run slightly less. Cost varies based on spring size, type, and whether additional repairs are needed.
