As in an elevator, the electric motor does not provide most of the power to move a heavy garage door. Instead, most of door's weight is offset by the counterbalance springs attached to the door. (Even manually operated garage doors have counterbalances; otherwise they would be too heavy for a person to open or close them.) In a typical design, torsion springs apply torque to a shaft, and that shaft applies a force to the garage door via steel counterbalance cables. The electric opener provides only a small amount of force to control how far the door opens and closes. In most cases, the garage door opener also holds the door closed in place of a lock.

Speed of a thrown winding bar:: The springs, being in balance with the door, effectively are able to launch a typical 150 lb door at 10.6 mph speed. An 18-inch long by 1/2-inch diameter steel winding bar happens to weigh about 1 pound. Since momentum is conserved, this 150:1 ratio in weight of the door to the winding bar means the fully-wound springs could potentially throw a winding bar at 10.6 mph * 150 = 1590 mph = 2332 ft/sec, assuming the energy were perfectly coupled and transferred. If the energy transfer were only 1/3 efficient, this would still be the 800 ft/sec speed of a typical pistol bullet. Except it is a foot-and-a-half metal spear, not a bullet.

Speed of a falling door:: Physics tells us that the transit time of a free-falling body is sqrt(2x/g), where x is the length of the fall and g is the acceleration due to gravity (32.2 ft/sec^2). If this typical 150 lb door were to fall an equivalent of 3.75 feet, this falling time would be sqrt(2*3.75/32.2) = 0.48 seconds (480 milliseconds). The terminal velocity is gt, or 0.48 seconds * 32.2 ft/sec^2 = 15.5 ft/sec = 10.6 mph.

Here are the winding rods inserted in the winding cone of the unbroken old spring, posed just for a picture. Note that I have carefully placed a sturdy, steady ladder just clear of the swing of the rods, such that when I am standing on the lower rungs to reach the rods, that my head and body are clear of the "kill zone" around the spring and cone. You must have a trustworthy platform to stand on, because a slip or shake of the ladder while you are winding can cause you to lose your socketed attachment to the cone, letting loose the spring. I would not trust an ordinary household step ladder for this purpose.
Insulation increases the efficiency of your door and can lower your electric will. You need R-value garage doors.

It would cost less to install a steel door with no opener then it would to install a wood door with an opener etc...

One can overwind the springs slightly, up to about 8 turns on a standard residential door (that is, 1/2 or 3/4 extra turns), to compensate for undersized or fatigued springs, or increased door weight from painting or humidity, but this results in more stress on the springs and therefore decreased lifetime. If the door is too heavy for that slight tweak, then different springs are needed.
The belt-driven Chamberlain B970 garage door opener is powerful and well-featured. With a 1.25 HPS motor, it's got all of the strength needed for just about any residential garage door, and the motor and belt are covered by a lifetime warranty.

An extension spring counterbalance system consists of a pair of stretched springs running parallel to the horizontal tracks. The springs lift the door through a system of pulleys and counterbalance cables running from the bottom corner brackets through the pulleys. When the door is raised, the springs contract, thus lifting the door as the tension is released. Typically these springs are made of 11 gauge galvanized steel, and the lengths of these springs are based on the height of the garage door in question. Their lifting weight capacity can best be identified by the color that is painted on the ends of the springs.
Customers who have purchased this garage door opener for their homes have been mostly satisfied with the performance of it. Many have raved about how quiet it actually is—one said instead of hearing the metal squeak and clank like with their last one, only the sound of the “wooden door being jostled around as it is pulled up and down” is all you hear with this one. Customers were also happy with the features including the automatic closer when you forget to shut it after you go inside. Some had had issues with the manual being hard to understand while installing it themselves. But most were happy with the overall performance.
Given the complexity of a garage door and opener system, there are a variety of different areas something could go wrong. If your garage door shakes or is very loud during operation, the garage door closes all the way only to immediately open back up, the garage door opens slowly or closes too quickly, or the garage door opener and remote aren't working at all, you should seek help from a professional garage door repair specialist.
Using your drill, add tension to the torsion spring. This system uses a single spring for a double door, but many manufacturers use two springs for a double door. The painted line on the spring acts as a gauge for the number of turns you put on the spring. To keep the bar from turning while you’re adding tension, attach a locking pliers to the bar on both ends of the spring. Apply lubricant for garage doors to the spring.

Wood doors range from midprice to very expensive, depending on whether they consist of a lightweight wooden frame filled with foam insulation and wrapped in a plywood or hardboard skin (the least expensive) or are true frame-and-panel doors made of durable mahogany, redwood, or cedar. Wood doors usually carry a short warranty, perhaps only one year. 


Make sure the door is balanced. Close the door and pull the emergency release cord (always close the door first so it can’t come crashing down!). Lift the door about halfway up and let go. The door shouldn’t move. If it slides up or down, the torsion spring needs to be adjusted (or maybe even replaced). Adjusting the torsion spring is dangerous, so don’t attempt it yourself (you could get seriously hurt). Call a pro to adjust it.
Most garage door openers are pretty expensive. So if you need an opener on a budget, the Genie 1035-V (also known as the Genie Chain Drive 500) gives you that desirable low price point. It doesn't have a lot of high-end tech features, nor will it manage heavy garage doors, but it does the basic work of raising and lowering the garage door perfectly well.
These springs weighed in at just over 9 pounds each, including the winding cones. They are covered with a light film of oil, and at this point the job starts to get messy. The manufacturer has painted them with a "225B24" part number, which no doubt indicates the 0.2253 inch wire size, 24 inches long. Perhaps the "B" indicates the 2-inch inside diameter. Both the left- and right-hand springs have this same number on them.
Called for an appointment and was surprised that I could have a tech come the same day. Matt arrived ahead of schedule, inspected the garage door and gave me a tune up to get things working properly again. He explained what would need to be done in the future, and the cost. I will certainly call them when the time comes to get that work done.read more
The two set-screws in the winding cones have a 3/8-inch square head, which fits a 3/8-inch open-end wrench or 8-point socket, or a 7/16-inch 12-point socket or 12-point closed-end wrench. I carried an extra wrench in my pocket while winding, since I didn't want to be holding a wound spring that I couldn't set because I had dropped the wrench (although one could rest the winding rod against the door in this case while picking up a dropped tool).

Roberto was very courteous and explained the details of what he was doing. He also pointed out a repair I might consider having done (replacement of the bottom panel of my door) and asked the office to follow up with me on this. Someone did follow up with me and since replacement of the bottom panel is not an option and I would have to replace the door, I decided that I can wait.
While there might not be a huge price range when it comes to garage door openers—they are all quite an investment—there a few less expensive options to consider. Here’s a great budget option from Chamberlain. It has a motor that’s equivalent to ½ horsepower and chain drive system that is quick and easy to install. You can also connect it to the MQ technology (gateway sold separately) to use with your smartphone.

It comes with a 10-year motor, two-year parts, and one-year accessories warranty.

If your door has two springs, most professionals and research online says that replacing both springs is the best option. Most torsion springs are rated for 10,000 close/open cycles. If only one of your springs is broken, both springs are still recommended to be replaced. Considering that your second spring will break soon anyways, this added on fix is only going to cost you about $50 extra to assure that you don't have to pay another service fee for a second visit.
Before purchasing a roll-up door, measure the space between the top of the garage door opening and the ceiling or overhead framing. Standard tracks require headroom of about 14 inches. If you don’t have that, you can get low-headroom track, which costs about $100 more. There are also tracks specially made for garages with unusually high walls or cathedral ceilings.

Tools in Action says the Ryobi Ultra Quiet has plenty of versatility, as you can plug devices into the opener hardware, like a Bluetooth speaker, a fan, or even an 18V Ryobi cordless tool battery. When the opener has power, it will charge the battery. But if your home ever loses power, the 18V battery works as a backup to the garage door opener, allowing it to operate normally.
Typically, it will cost less to install a steel garage door without an opener than to install a custom wood door with a garage door opener. Recent innovations have also yielded high-tech doors with thick insulation and energy-efficient glaze, as well as finished interior surfaces and other significant upgrades. These are more expensive doors, but they are also extremely durable.
