I was told by a garage door repair man in S. Florida that the springs are good for so many openings, not a certain amount of time. Some tend to use theirs like me, all the time and never the front door. The springs he replace I figured had just made the number of openings he told me. I can't remember the number but mine only lasted me about 5 years.
I found this on Google:
Here is a simple explanation to explain how and why springs break. Take a piece of coat hanger wire and bend it in two. Now straighten it out, and then bend it in two again. Keep doing this. We all know that the wire will eventually break, depending on two things, How many times you wobble it back and forth, and the quality of the wire to begin with.
The same thing is happening to your door. Every time the door comes down, the spring winds up to full tension. Every time you open the door, the spring un-winds. All your doing is wobbling metal back and forth, just like the coat hangar wire.
This is a long winded way of saying, springs break because of the "number" of times the door goes up and down. (we call it cycles)
Springs are available in various calculated cycle lifes. Some of the builders grade doors that you would get in a new subdivision can be as low as 5 thousand cycles. Most new higher end doors have 15 thousand cycle springs.
Lets say you have the higher end springs, at 15 thousand.
If you have a door that goes from the garage into the house, then chances are, that is your main entrance way into the house, through the garage. If so, then it's not unusual for your door to go up and down a minimum of 10 times a day. Thats 3650 times a year, and at that rate, your 15 thousand cycles would be used up in just over 4 years.
If your garage is used for parking or storage and not as an entrance into the house, then the spring would last many years longer.
You can request springs that can be made with a calculated cycle life of 50-100 thousand cycles, but like anything else, the price will be commensurate. Some of the older doors really do have springs that lasted 30-40 years.
Keeping the springs oiled, or well lubricated so that the coils can rub on each other smoothly as the spring twists, will enhance the life of the spring. If springs are allowed to get rusty, then the springs will jerk and make a chunk-chunk sound as the door is being opened.
Bus driver is right on when he says the cold affects them. Springs that are close to the breaking point will be pushed to the breaking point by very cold weather. When the temperature goes real cold in December, we get a rash of calls for doors that won't open in the morning, all of them with broken springs. (steel contracts when it's cold, causing more stress on the spring)
Torsion springs are not something you want to fool around with. Next time to get a company to intall springs, get them to "up" the cycle life as high as they can. They have charts and graphs that allow them to do that.
