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

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