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

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