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

Drops — undersprung, winding adjusted in Mountain View Ranches, AZ. Opener reconnected only after balance test confirms correct specification in Mountain View Ranches.
Both springs were installed at the same time and have completed the same number of cycles in Mountain View Ranches, AZ. Metal fatigue accumulates proportionally to cycles under stress in Mountain View Ranches. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Mountain View Ranches, AZ. The surviving spring is at essentially the same point in its fatigue progression in Mountain View Ranches.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Mountain View Ranches, 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 Mountain View Ranches. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Mountain View Ranches, 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 Mountain View Ranches. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Mountain View Ranches, AZ. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Mountain View Ranches. The specific reasoning is explained clearly in Mountain View Ranches, AZ. The homeowner makes the final decision with complete information in Mountain View Ranches. Herlihy never withholds the reasoning or pressures the outcome in Mountain View Ranches, AZ.
