Springs matched to the door
Weight, height and the lift arrangement decide which springs are correct. Two coils that look alike can be wound and rated very differently, and a near-enough spring wears out early.
A broken spring leaves the door far heavier than the opener was built to lift. Stop using the button and let Chandler Garage Door Experts inspect the springs, cables, drums and bearings before anything is replaced.
Springs are rated in cycles, not years. A Chandler household that uses the garage as its main way in and out can run through a builder's standard spring far sooner than the label suggests, and in neighborhoods finished in the late 1990s and 2000s the original springs, cables and rollers tend to reach that point together.

Not every visit needs every item below. Chandler Garage Door Experts separates the repair the diagnosis calls for from work you may choose to do later.

The spring never works alone. Cables, drums, the shaft and its bearings are inspected while the system is apart, because a worn part alongside a new spring shortens its life.
Once the springs are set, the door is tested by hand and through the opener, and the reverse and sensor functions are rechecked. The motor should not be compensating for a door that is out of balance.
The quote should name the failed part, the compatible replacement and any related work found during the inspection. If a second component is close to failing, you should hear about it as an option rather than find it bundled into the invoice.
Spring failure often shows up alongside worn cables and rollers, and a door that has been forced since the bang may also need off-track work. If the door itself is tired, the repair versus replacement guide is the place to start.

The door's weight and lift arrangement, whether one or both springs are being replaced and whether the cables, drums or bearings also need work. Chandler Garage Door Experts gives you that breakdown on site, before the repair begins, rather than a figure over the phone.
On a two-spring door they have almost always run the same number of cycles, so replacing the pair is usually the sensible call. Chandler Garage Door Experts will explain what the second spring looks like and let you decide, and the repair versus replacement guide covers when the whole door is the better conversation.
No. With the spring gone the door's full weight is unsupported, and it can drop fast enough to cause serious injury. Leave the emergency release alone, keep people and vehicles clear, and tell Chandler Garage Door Experts whether a car is shut inside when you request the visit.
Standard residential springs are commonly stocked, so a same-day repair is often possible depending on scheduling and what the inspection finds. Unusual sizes or high-cycle springs may need ordering; Chandler Garage Door Experts confirms the timing once the door has been seen. See how a visit is arranged.
