Torsion Spring Replacement in Glendale, AZ
Torsion springs mount horizontally on a steel shaft directly above a closed garage door and twist — rather than stretch — to store lifting energy. They’re the standard system on most doors built or replaced since the 1990s.
Local context for Glendale
Homes around Glendale deal with intense sun exposure and low humidity, a combination that can dry out spring lubricant and cable sheathing faster than in milder climates.
A torsion spring system consists of one or two springs wound tightly around a steel shaft that runs above the door opening, with cable drums at each end that spool the lift cables as the door rises. Instead of stretching like an extension spring, a torsion spring twists — winding tighter as the door closes and unwinding to release energy as the door opens. This design distributes weight evenly and is generally considered more durable and controllable than an extension-spring layout, which is why it’s become the standard on most doors manufactured in the last few decades.
Because the shaft and springs sit directly above the door opening, a torsion spring failure is unmistakable: a loud bang, a stuck or extremely heavy door, and sometimes a visible gap in the coil where the spring separated. Sizing a replacement torsion spring correctly requires the door’s exact weight along with the spring’s wire diameter, inside diameter, and length — get any of those wrong and the door will either strain the opener (spring too weak) or refuse to stay closed (spring too strong).
Torsion Spring Replacement problems we see in Glendale
Heat-driven spring lubricant breakdown
Intense sun exposure and sustained high temperatures can dry out spring lubricant faster than in milder climates, increasing coil friction and wear.
Thermal expansion on torsion bar hardware
Large day-to-night temperature swings cause the torsion bar and mounting hardware to expand and contract, which can gradually affect spring alignment.
Visible separation in the spring coils
A clean gap between coils on the shaft confirms the spring has already snapped, even if the door hasn’t been operated since.
Loud bang directly above the closed door
The shaft-mounted torsion spring is positioned right above the door, so a failure is usually heard and felt at that specific location.
Frequently asked questions
What garage door spring problems are most common in Glendale?
The most common issues we see reported in areas like Glendale are broken torsion springs, worn extension springs, and cable fraying near the spring drum — often tied to the local climate and age of the home's hardware.
Can one torsion spring be replaced without touching the other?
On a two-spring shaft, most technicians recommend replacing both at the same time even if only one failed, since they were installed together and are typically near the same point in their cycle life — replacing only one often leaves the door slightly unbalanced going forward.
How is a torsion spring different from an extension spring?
A torsion spring is mounted horizontally on a shaft above the door and stores energy by twisting; an extension spring is mounted above the horizontal tracks on either side of the door and stores energy by stretching. Torsion systems are the more common modern standard and are generally regarded as more durable and controllable.
