Unlike torsion springs, replacing extension springs has long been given the "green light" for DIYers, primarily because you can complete the job without having to deal with spring tension. The general process is simple and safe: open the door to relieve the spring tension (and secure it open with C-clamps in the tracks); disconnect the spring from the track bracket and the spring pulley, and disconnect the safety cable from one end; install the new spring, reinstall the pulley, and reconnect the safety cable, and you're done.
My garage door torsion spring broke so I decided to replace it myself. Shipping was next day. I got the torsion spring rod at a local hardware store. Easy to install once I figure out how to lock down the rod from moving and loosening the door cable on the side. Instructions tells you how to do it. Great replacement spring and save $$$ doing it myself. https://m.youtube.com/watch?v=Z_eZc-kh40c
Garage Door Installation – This includes the installation of a new garage door. Includes the door itself, the track, cables, springs, hinges, handles, locks and rollers. It is the complete service and installation of a new door. We inspect all the parts, make adjustments to fit your garage opening, and service all elements during the installation process. Plus, we check to ensure all parts are in proper working order after installed.

9.12 It is now time to secure the torsion springs in the middle. For various reasons, many installers will offset the center bracket several inches from the center of the door. Offsetting the bracket makes it easier to work around the opener bracket without causing any problems in the operation of your garage door, but offsetting the bracket is not necessary. If you have a slotted center bracket, remove the vise grip and lube the shaft where it turns inside the bushing. Position the shaft so it is the same distance from the header as it is at each end. The shaft should be straight and parallel to the header.
It is very important that the replacement springs are calibrated for the weight of your door. Using the wrong size garage door springs will caused the to not function properly and could also cause the opener to break much quicker. Replacing extension springs can be very dangerous and if done wrong can harm someone using the garage door. Make sure you call the Garage Door Doctor to ensure your garage is repaired properly!
Delivered on time, with the products described: springs, winding bats, & plastic bushing. Quick install, but apparently I measured wrong, so these total length I bought was larger (which is good as there is less stress on the spring). However this did mean that I needed more than the generic rule of 30 1/4-turns of preload. I wound up with 38 1/4-turns per side for the door to balance when open 3' (per familyhandyman.com recommendations). Would definitely do it again. http://www.youtube.com/watch?v=Z_eZc-kh40c&feature=kp
So if you’re worried that your door may be becoming more energy inefficient or if you’ve noticed a sudden spike in your heating costs, look at the weather stripping on your garage door. While you can replace it yourself, remember that effective weather stripping requires a tight seal, so if you’re unsure, you might save money in the long run by going with a professional garage door service
4. It is also important to note that extension springs sometimes do not break but rather ‘stretch out’. This is easy to spot as the space between coils when the door is closed is normally consistent. When the spring fails without breaking the space between the coils will become very inconsistent. This condition is quite visible and if it exists the springs should be replaced (Know when to call quits with your garage door).

3. On an extension, or stretch type spring there is little you can do to extend the service life. On a torsion spring (the type that is wound on a bar rather than stretching out) you can help ensure a full cycle life by lightly lubricating the coils of the spring to reduce friction. If your garage door sees a lot of use and spring failure is an ongoing concern it can be addressed by selecting extended cycle springs. Discuss this upgrade when calling in for spring service, your service advisor will assist in making the correct choice for your needs.

Most homeowners never know they have a broken garage door spring until they try to leave their home. You go in the garage to open the door, push the wall button, and the door only goes up 6”. The reason for this is the garage door opener force or sensitivity has activated, causing the opener to stop pulling the door up. This is a safety feature built into most garage door openers. It is actually a good thing when the open force activates to prevent any damage to your garage door or opener.

If this is the problem then you will be able to tell by seeing if your garage door rollers are literally off track. If your garage door panels are not damaged, then you do not need to replace your door. However, the rollers do need to be put back on the track which should be done by a professional.

Garage door springs support most of the weight of the door when it's opening and closing. A broken spring typically will make the door very hard to lift, rather than causing the door to stick halfway. But some spring problems can contribute to a stuck door. The springs help turn metal wheels, called pulleys, that help lift the door via vertical cables at each side of the door. A pulley can become jammed by an obstruction or possibly a misaligned or hung-up cable. Any problems with springs or pulley should be examined by a garage door professional. Springs (and pulleys) are highly tensioned and can be very dangerous to work with.
9.9 Go to the other side of the garage door and insert the end of the cable into the drum. Rotate the drum until the cable is tight. Slide the drum against the bearing and push the shaft to the right. The marks should line up. If they don't, figure out why and correct the problem. It could be a stuck cable, the garage floor may have shifted, or the vertical angle that helps support the bearing plate may have loosened and shifted. Many garage doors have been installed with a gap between a drum and a bearing plate. The cable drums should always be flush against the race of the bearings.
