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

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