The door feels heavier than it used to when you lift it manually in Kaibab Estates West — the spring is losing tension and the door weight is progressively shifting to the opener, the cables, and your effort in Kaibab Estates West, AZ. The opener strains audibly and the door moves more slowly than it should in Kaibab Estates West — the spring isn't providing its full counterbalancing force and the opener is compensating with every cycle in Kaibab Estates West, AZ. Or a spring snapped — you heard the bang and the door won't move in Kaibab Estates West. Call Herlihy Garage Doors now for same-day spring repair throughout Kaibab Estates West, AZ in Kaibab Estates West. Do not run the opener and do not attempt to manually lift the door after a spring snap in Kaibab Estates West, AZ.
Garage door spring work is the most safety-critical service in the garage door industry for a specific reason in Kaibab Estates West. A residential torsion spring stores several hundred foot-pounds of rotational energy when wound to operating tension in Kaibab Estates West, AZ. That energy is released in a controlled way when the door opens through the spring's correct unwinding in Kaibab Estates West. It releases in an uncontrolled way when a tool slips from the winding cone during spring replacement in Kaibab Estates West, AZ. The winding cone has four holes designed for professional winding bars of a specific diameter in Kaibab Estates West. A winding bar that fits these holes correctly maintains contact throughout the winding process in Kaibab Estates West, AZ. An improvised tool — a screwdriver, a piece of rebar, anything that doesn't fill the hole correctly — can slip out of the cone at any point in the winding process in Kaibab Estates West. When it slips, the stored energy releases instantly and the cone rotates at high speed in Kaibab Estates West, AZ. The improvised tool becomes a projectile in Kaibab Estates West. This is not a theoretical risk in Kaibab Estates West, AZ. It's the mechanism behind the serious injuries that occur from DIY spring replacement every year in Kaibab Estates West.
Herlihy Garage Doors repairs and replaces garage door springs throughout Kaibab Estates West, AZ in Kaibab Estates West. The correct specification is measured from the specific door configuration before any spring is selected in Kaibab Estates West, AZ. The replacement spring is wound to the correct turn count for the specific door height and cable drum in Kaibab Estates West. The balance test confirms the specification is correct before the opener is reconnected in Kaibab Estates West, AZ. Same-day service available throughout Kaibab Estates West in most cases in Kaibab Estates West, AZ. And every spring repair is guaranteed in Kaibab Estates West.
A spring replaced with an incorrect specification — wrong wire diameter, wrong inside diameter, or wrong length — produces a door that's either oversprung or undersprung regardless of how correctly it's wound in Kaibab Estates West. An oversprung door can behave dangerously under manual operation in Kaibab Estates West, AZ. An undersprung door adds abnormal load to the opener motor, drive gear, and cables on every cycle in Kaibab Estates West. Neither produces the correctly balanced door that every other component in the system depends on in Kaibab Estates West, AZ. Herlihy Garage Doors measures the correct specification before any spring is selected in Kaibab Estates West.
The spring specification determines the door's balance in Kaibab Estates West, AZ. The door's balance determines the load the opener, cables, and rollers operate under in Kaibab Estates West. Every component in the door system performs correctly when the spring is correctly specified and performs under abnormal load when it isn't in Kaibab Estates West, AZ. The spring specification is the foundation variable from which everything else in the system's performance follows in Kaibab Estates West.
A torsion spring is mounted on a steel shaft directly above the garage door opening in Kaibab Estates West, AZ. When the door closes, the cables pull down on the cable drums, rotating the shaft and winding the spring tighter in Kaibab Estates West. The winding stores rotational energy in the spring coil in Kaibab Estates West, AZ. When the door opens, the spring unwinds and releases that stored rotational energy through the shaft and drums, lifting the cables and the door in Kaibab Estates West. The spring is wound to a specific tension that produces a lifting force equal to the door's weight at the cable drum attachment points in Kaibab Estates West, AZ. This counterbalancing force is what makes a 200-pound garage door movable with 10 to 20 pounds of net force from the opener in Kaibab Estates West.
Extension springs run horizontally along the upper track sections on each side of the door in Kaibab Estates West. They store energy by stretching rather than rotating in Kaibab Estates West, AZ. When the door closes, the springs extend and store energy in their stretched length in Kaibab Estates West. Extension springs can break with significant lateral movement because the stored energy is released along the spring's length rather than through a shaft in Kaibab Estates West, AZ. Safety cables threaded through the center of each extension spring are required to contain a broken spring and prevent it from becoming a projectile in Kaibab Estates West. Herlihy Garage Doors inspects and installs safety cables on every extension spring service in Kaibab Estates West, AZ.
Wire diameter determines how much energy the spring stores per turn in Kaibab Estates West, AZ. A heavier wire diameter stores more energy per turn than a lighter one in Kaibab Estates West. Inside diameter determines which shaft size the spring fits on in Kaibab Estates West, AZ. Length determines the total number of active coils and therefore the total energy storage capacity in Kaibab Estates West. All three must be correct for the spring to produce the correct counterbalancing force for the specific door when wound to the correct turn count in Kaibab Estates West, AZ.
A spring with the correct inside diameter and length but a wire diameter one gauge too light stores less energy per turn than needed in Kaibab Estates West. Winding it to the correct turn count produces insufficient lifting force in Kaibab Estates West, AZ. The door is undersprung in Kaibab Estates West. A spring with the correct wire diameter and inside diameter but a length that's too short has fewer active coils in Kaibab Estates West, AZ. Each coil must be wound tighter than designed to produce the required energy storage in Kaibab Estates West. The spring is more likely to fail before its rated cycle life in Kaibab Estates West, AZ.
Herlihy Garage Doors determines the correct spring specification through measurement of the existing spring where intact, or through calculation from the door's measured dimensions and construction characteristics where the spring has failed in Kaibab Estates West, AZ. Door height and cable drum size determine the correct winding turn count in Kaibab Estates West. Door weight estimated from size, steel gauge, insulation type, and window configuration determines the correct wire diameter and length in Kaibab Estates West, AZ. The specification is calculated, not estimated in Kaibab Estates West.
A standard residential torsion spring for a 200-pound garage door stores approximately 300 to 400 foot-pounds of rotational energy when wound to operating tension in Kaibab Estates West, AZ. Three hundred foot-pounds is the equivalent of a 150-pound weight dropping two feet in Kaibab Estates West. That energy is stored in the spring coil as rotational tension on a steel shaft in Kaibab Estates West, AZ. When released correctly during spring replacement, it simply unwinds the spring back to the neutral state in Kaibab Estates West. When it releases suddenly during a tool slip, it releases all at once through the winding cone in Kaibab Estates West, AZ.
The winding cone has four holes sized for professional winding bars of a specific diameter in Kaibab Estates West. Professional winding bars are 18 to 24 inches long and the correct diameter to fill the winding cone holes with minimal play in Kaibab Estates West, AZ. The length provides leverage and clearance in Kaibab Estates West. The correct diameter fit prevents the bar from shifting in the hole during winding in Kaibab Estates West, AZ. Any movement of the bar in the hole during winding is a slip hazard in Kaibab Estates West.
An improvised tool that's too narrow to fill the winding cone hole can shift in the hole during winding in Kaibab Estates West, AZ. When it shifts far enough to exit the hole, the stored rotational energy in the spring releases through the winding cone in Kaibab Estates West. The cone rotates rapidly in Kaibab Estates West, AZ. The tool that was in the hole becomes a projectile in Kaibab Estates West. The person holding the tool, whose hands were near the winding cone, is in the path of both the rotating cone and the released tool in Kaibab Estates West, AZ. This mechanism produces the serious hand and arm injuries that occur from DIY spring replacement in Kaibab Estates West.
Understanding the correct procedure for spring replacement and executing it correctly under real installation conditions are different things in Kaibab Estates West. Professional technicians have performed the winding procedure under training supervision and accumulated the repetitions that produce correct automatic body positioning in Kaibab Estates West, AZ. Correct positioning keeps the technician's body out of the path of energy release throughout the winding sequence in Kaibab Estates West. That positioning is as important as the correct tools in Kaibab Estates West, AZ.
Herlihy Garage Doors technicians carry professional winding bars sized for the winding cones on common residential torsion springs in Kaibab Estates West, AZ. They follow correct winding procedures that maintain safe positioning relative to the spring and winding cone throughout the winding sequence in Kaibab Estates West. They've accumulated the training repetitions that make correct positioning automatic in Kaibab Estates West, AZ.
A spring that's losing tension provides less counterbalancing force than the door weight requires in Kaibab Estates West, AZ. Disconnecting the opener and manually lifting the door reveals a door that's noticeably heavier than it was in Kaibab Estates West. This progressive increase in felt weight is the spring's tension loss accumulating cycle by cycle in Kaibab Estates West, AZ.
A spring that isn't fully counterbalancing the door transfers the uncounterbalanced weight to the opener motor on every opening cycle in Kaibab Estates West. The motor runs at a higher load than designed in Kaibab Estates West, AZ. It produces more heat. It accumulates wear faster in Kaibab Estates West. The door moves more slowly because the opener is doing significantly more mechanical work than designed in Kaibab Estates West, AZ.
A torsion spring failure produces a sharp loud bang as the stored rotational tension releases at the fracture point in Kaibab Estates West, AZ. The bang is often heard throughout the home in Kaibab Estates West. The door either drops if in motion or stays at its current position in Kaibab Estates West, AZ. The opener runs but the door won't follow in Kaibab Estates West. Do not run the opener after a spring snap in Kaibab Estates West, AZ.
A broken torsion spring separates at the fracture point and creates a visible gap in the continuous coil in Kaibab Estates West. The gap is typically one to three inches wide and is visible by looking at the spring on the shaft above the door in Kaibab Estates West, AZ. A visible gap means complete spring failure in Kaibab Estates West. The door should not be operated until the spring is replaced in Kaibab Estates West, AZ.
A door that's noticeably higher on one side during operation has unequal spring tension or cable tension between the two sides in Kaibab Estates West, AZ. On a two-spring system, a spring that has lost tension on one side produces a door that rises unevenly in Kaibab Estates West. Herlihy Garage Doors assesses spring condition on both sides when uneven door travel is reported in Kaibab Estates West, AZ.

Both springs were installed at the same time and have completed the same number of cycles in Kaibab Estates West, AZ. Metal fatigue accumulates proportionally to cycles under stress in Kaibab Estates West. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Kaibab Estates West, AZ. The surviving spring is at essentially the same point in its fatigue progression in Kaibab Estates West.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Kaibab Estates West, AZ. When the second spring breaks — and at the same fatigue progression it will — the cost is a second call-out charge, a second spring, and potentially a second after-hours charge in Kaibab Estates West. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Kaibab Estates West, AZ.
If the surviving spring was replaced recently and has significantly fewer cycles than the broken spring, replacing only the broken spring is the correct approach in Kaibab Estates West. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Kaibab Estates West, AZ. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Kaibab Estates West. The specific reasoning is explained clearly in Kaibab Estates West, AZ.
