How Torsion Springs Power Your Garage Door07/20/2016 Back To Blog
If you have been shopping around for garage door motors, you have probably noticed that they come with different horsepower ratings. While more horsepower does help lift heavier doors and at faster speeds, it can be a misleading measurement of the power and performance of a garage door opener. The truth is that most of the heavy work is done by the torsion springs, which are often located on the wall directly above the garage door opening.
You probably think of springs as stretching and closing, much like a Slinky or the spring on your front door screen. However, a torsion spring generates mechanical energy by twisting. In the case of garage doors, the spring is anchored on one side with a stationary cone and the other end has a winding cone. When you open the garage door, the springs unwind and turn the cable drums, which in turn wrap up and store the cables. While the springs are in a constant state of tension, the amount of tension varies according to whether the door is being opened or closed. Either way, you can imagine that being in a perpetual state of tension would eventually cause some wear and tear.
Replacing Torsion Springs
The good news is that you should only have to worry about garage door torsion spring replacement about every 10 to 20 years depending on the quality of your equipment and how often you use the door. There are two sure signs that you are due for some maintenance and service. First, if you are consistently hearing squeaking noises, it is probably time to have the components lubricated. Second, if you disconnect your door from the motor and manually close it, you should notice that is gently hits the ground. However, if it appears to be sagging, you should call a garage door service company and ask about torsion spring repair services.
If it is time for some repairs, the prices for springs usually range from $60 to $150, depending on the spring's size and type. However, replacing springs can be dangerous and only attempted by experts. Not only are you dealing with electrical components that can cause a shock, you also have to navigate a heavy door and powerful springs that are loaded with tension. Unless you have some experience and training, your best bet is to call on a reputable garage door company. Once you factor in service fees, you can expect to pay around $100 - $350 to have new springs installed.
