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

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