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.
An opener is designed to move a door that is already balanced, and every safety feature in it assumes that. The force it applies is limited so the door will stop and reverse when it meets something, and that limit only makes sense when the door is close to weightless. When springs lose tension, the opener has to lift real weight, its motor and gears work harder, and it may reverse or stall for no obvious reason. A balance adjustment puts the weight back on the springs where it belongs, so the opener can return to the light duty it was built for and its reversing behaviour is dependable again.

Scene 1
A door that is out of level is usually a cable story rather than a spring story. The technician checks that each cable wraps its drum in a single neat layer with the same number of wraps on both sides, that the drum set screws are tight on the shaft, and that neither cable is frayed or rusting at the bottom bracket. A tape across the bottom of the door in the closed position shows whether one corner sits high. If it does, the cables are reset on the drums so the door is level before spring tension is judged, because a crooked door binds in its track and feels heavy regardless of how the springs are wound.
Scene 2
If one corner of the door sat high, that is corrected before the final tension is set. The technician releases the spring tension enough to take the load off the drums, loosens the set screws on the drum on the low side, takes up or lets out cable until the door is level, and locks the drum again with the cable seated snugly in its groove. The bottom of the door is checked against the floor along its whole width, and both drums are confirmed to show the same number of wraps. Only then is the spring tension brought back up, because tension applied to a crooked door simply loads one side more.
Scene 3
Before leaving, the technician tells you how the door was set: the number of turns on each torsion spring or the hook position on each extension spring, the spring dimensions, the door's measured weight if it was weighed, and any parts that were replaced. Writing this on a card by the opener or inside the manual saves a future technician from starting from scratch, and it gives a reference point if the door ever starts to drift. Springs age gradually, so a note that says the door held at a certain number of turns tells a later visit how far things have moved.

It means the springs carry nearly all of the door's weight, so the door itself feels close to weightless. Balanced, it will stay put at any partly open position when moved by hand, stay fully open on its own, and close without slamming. The opener then only has to guide the door rather than lift it, which is how it was designed to work.
Yes, and installers will usually insist on it. A new opener is set up against the door it meets on the day, so its travel and force settings are only right if the door is already balanced. Fitting a new motor to a heavy door shortens the motor's life and puts the safety reversal out of range. Balancing first means the new opener starts life doing the light work it was designed for.
The opener is built to move a balanced door, and its force limit is what makes it stop and reverse on contact. Raising that limit to lift a heavy door pushes the safety behaviour out of its intended range and works the motor and gears hard. The sound order is to balance the door first, then set the opener to suit it. Both are done in the same visit.
