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

Replacement spring installed on the shaft in Air Force Academy. Winding cone positioned correctly in Air Force Academy, CO. Spring wound to the calculated turn count using professional winding bars in Air Force Academy. Set screws tightened to correct specification in Air Force Academy, CO. Cables reattached to drums with correct tension in Air Force Academy.
Opener disconnected. Door manually lifted to halfway position in Air Force Academy, CO. Door released and observed in Air Force Academy. Holds at halfway — specification confirmed correct in Air Force Academy, CO. Rises — oversprung, winding adjusted in Air Force Academy. Drops — undersprung, winding adjusted in Air Force Academy, CO. Opener reconnected only after balance test confirms correct specification in Air Force Academy.
Both springs were installed at the same time and have completed the same number of cycles in Air Force Academy, CO. Metal fatigue accumulates proportionally to cycles under stress in Air Force Academy. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Air Force Academy, CO. The surviving spring is at essentially the same point in its fatigue progression in Air Force Academy.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Air Force Academy, CO. 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 Air Force Academy. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Air Force Academy, CO.
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 Air Force Academy. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Air Force Academy, CO. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Air Force Academy. The specific reasoning is explained clearly in Air Force Academy, CO. The homeowner makes the final decision with complete information in Air Force Academy. Herlihy never withholds the reasoning or pressures the outcome in Air Force Academy, CO.
