The opener has started to groan on the way up. The door climbs slowly, hesitates near the top, and on the way down it sometimes stops a hand's width above the floor and reverses, as if something were in the way when nothing is.
On a torsion door the springs sit on a shaft above the opening, and balance is set by how many turns of wind they carry. A seven-foot door typically needs a little over seven full turns; a quarter turn either way changes how the door feels. The technician clamps the door, fits winding bars into the cone, loosens the set screws, and adds or releases tension one quarter turn at a time, locking the cone again before each test. Both springs on a two-spring door are set alike so the shaft carries the load evenly. That precision is what makes the door hold wherever it is stopped.

Scene 1
Springs are sized to a door's weight, so the technician asks what has changed since the door was installed. Insulated panels fitted over the original skins, a section replaced after a bump, a row of windows, a heavier bottom seal or decorative hardware all add weight, and even a fresh coat of paint on a wood door counts. Where the history is uncertain, the door can be weighed with the springs relaxed, using a scale under the bottom section. That figure tells the technician whether the existing springs can be adjusted to carry the door or whether the door has outgrown them and needs a different spring specification.
Scene 2
With one winding bar seated firmly in the winding cone and a second ready, the technician loosens the cone's set screws and either adds tension by levering the bar upward or releases it by letting the bar down, always a quarter turn at a time, always with a bar in the cone. After each quarter turn the set screws are tightened onto the shaft, the clamp is removed and the door is lifted by hand to test. A door that sank now holds a little higher; a door that climbed now settles. On a two-spring door the same change is made to both springs so they share the load equally.
Scene 3
Once a month, with the door closed and the light on, look up at the drums and down at the bottom brackets. Each cable should wrap its drum in a single neat layer with the same number of turns on both sides, and hang taut without fraying or rust at the bottom loop. The gap under the door should be even from corner to corner. On an extension door, glance at the two springs for equal length and confirm the containment cable still runs through each. These take less than a minute and tell you the door is still level and the counterbalance still shares the load evenly.

Often, yes. A door that has grown heavy makes the opener labour, the chain or belt slap, and the rollers and hinges complain under load they were never meant to carry. Balancing the door takes that load back onto the springs, and the lubrication and roller checks that come with the visit quiet the rest. A door that runs silently is usually a door that runs light.
A torsion door has springs on a shaft above the opening, and tension is changed by winding the springs with steel bars, a quarter turn at a time. An extension door has springs along the tracks, and tension is changed by moving the hook or cable clip to a different position with the door open and clamped. The hand test that proves the result is the same for both.
With the door closed, the opener is released so the door is free. It is lifted by hand to about a metre, then to fully open, and let go at each point. A door in balance holds its position; one that rises on its own is over-tensioned and one that drops is under-tensioned. The door should also move freely and no faster than the hand pushing it.
