The home inspector's report on the house you are buying flags the garage door: extension springs with no safety cable running through them, coils showing rust, and a door that sank when he lifted it partway. The seller has never had it looked at.
A spring visit follows a fixed order, so you know what to expect. The technician releases the opener, raises the door fully and clamps it, because an extension spring is at its slackest with the door open. Then both springs, the pulleys, cables, hangers and containment cables are inspected and the door is weighed. Old springs come off, new ones go on with containment cables threaded through, cables are routed over the pulleys and both sides are hooked at the same setting. The clamps come off, the door is balanced by hand, and only then is the opener reconnected, adjusted and put through its reversal tests.

Scene 1
Even when only one spring has snapped, both are read closely. The technician looks for gaps opening between coils with the door up, which means the wire has stretched and lost its pull; rust pitting and scale, especially where the spring sits nearest the back wall; a spring hanging visibly longer or lower than its partner; and end loops that have opened or cracked. The two are compared for length, coil diameter and wire size, because springs of different ratings are sometimes found on the same door after a past repair. Whatever is found, the outcome is the same, a new matched pair, but the reading tells the technician what rating the door really needs.
Scene 2
Each lift cable starts at the bottom bracket, where its loop goes over the pin or is secured with a clevis pin. From there it runs up the vertical track, over the fixed pulley at the front of the horizontal track, back along the track to the pulley on the end of the spring, around it, and forward again to the S-hook or adjusting clip at the front hanger. The technician keeps the cable seated in each pulley groove and makes sure it passes on the correct side of the containment cable and the track. Cables are renewed if the old ones showed any fraying or rust, and always as a pair of the same length.
Scene 3
You can confirm the springs are still doing their share without going near them. With the door closed and nobody in the opening, pull the opener's red release cord so the trolley lets go of the door. Lift the door by its handle to roughly hip height and take your hands away. A door on good springs stays about where it is; if it sinks to the floor the springs have weakened, and if it rises on its own they are pulling harder than the door weighs. Either way it is a call rather than a job for you. Reconnect the opener the way your manual describes, usually by running it once.

Yes, and it is one of the more common reasons a pair of springs is suddenly found wanting. Insulation panels, glazed sections, a wood overlay or a new steel skin all add weight the original springs were never chosen for, so the door grows heavy and the opener strains. When the springs are replaced, the door is weighed as it is now, and the new pair is rated for the door you actually have.
Three things. Spray the springs, pulley axles and hinges with a garage-door lubricant twice a year, which slows rust in an unheated garage. Keep the threshold clear of bins and packed snow so the door never stops short with the springs still pulling. And leave the opener's force setting where the technician put it, since a door that starts needing more push is a balance question rather than a dial to turn.
Sometimes, and it is worth asking. A torsion system needs room above the door opening for its shaft and a header that can carry the spring bracket, which many older garages with a low ceiling simply lack; extension springs are there for that reason. Where the headroom exists, a conversion is a separate job with its own hardware and quote. The technician can tell you on the spot which route suits your garage.
