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

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