There are two kinds of garage door springs -- torsion springs and extension springs. Torsion springs are the kind wound-up on a rod above the garage door opening. There are a pair of them--one on each side of the center of the door. When one breaks the other often follows, so save the cost of another service call, and have both replaced when one breaks. People have been maimed and some killed tightening or releasing these springs.
Hire a professional.
If you are hell bent on replacing one yourself rent a spring tensioning tool--probably have to find one at a garage door company. They look something like long handled bolt cutters but, the business end it a ratchet to hold the bar as you tension the spring. USING INDIVIDUAL CRANKING BARS IS DANGEROUS. Skydiving is safer.
Here is a chap who uses ridicule and sarcasm to say you're a woussie if you're afraid to do this job yourself, equating the danger to cleaning your gutters or fixing your car. Keep in mind the many reports of people being maimed doing this as you read his quite thorough instructions, then decide if you want to spend 4-6 hours to earn about $70 this way.
