Note that I am measuring a spring that is fully relaxed because it is broken!. The length of the relaxed, unbroken spring is the specification of interest. It is harder to measure unbroken springs on an intact door because the springs should not fully unwind, even at the top-of-travel. If you can't be certain of the spring diameter from indications on the cones, then you have to go through an unwinding procedure to relax them fully for measurement, or perhaps reckon the size from measuring the somewhat smaller diameter at the nearly unwound condition when the door is at its top-of-travel (although one should not attempt to raise a door with a broken spring).
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.
Keep in mind that when the springs are released there is nothing to help with weight replacement. Garage doors weigh 150 pounds or more and if the door were not locked in place, there would need to be some way of holding it up until it can be lower manually. If no one is available to help, a clamp can be put on the track at the end of the door (Image 1). When ready, release the clamp and take the weight of the door.
The one excuse that makes the most sense is, "if we sell springs to a do-it-yourselfer, and he gets hurt installing it, we could get sued." I can sympathize with someone who wants to sell only to the trade and not bother with the risk of a spurious product liability lawsuit from an ignorant member of the public. But the lawn-mower dealers have figured out how to manage that kind of exposure, so this is not an absolute barrier to retailing garage door parts to the public. It doesn't explain why torsion springs at retail are virtually non-existent.
Screw - Screw-driven lift systems attach a long screw to the motor to move the garage door. These systems are powerful, fast, relatively quiet and require less maintenance than typical chain- or belt-driven systems. Genie and Overhead Door are two popular brands that make screw-driven systems. Based on our research of Genie’s line, you can expect to pay $244 on average for a screw-driven garage door opener.
Michael Davis replaced the tension springs and just about everything else that moves on both of my single car garage doors. I think I paid a premium price ($900) but I also believe I got the quality of service I paid for. Both doors are balanced and glide effortlessly and quietly along the tracks. Michael took the time to inspect and adjust every aspect of the garage door system including the opener (which I installed myself).read more

When buying an opener, choose a 1/3 hp or 1/2 hp opener for a single garage door (1/3 hp can be hard to find at some home centers). Go with 1/2 hp for a double door and 3/4 hp for a door that has a wood or faux wood overlay (they can be heavy!). Openers have a set opening speed, so installing an opener with a higher horsepower won’t open your door any faster.

With good looks, modest cost, and solid return on your investment, a new garage door is the Triple Crown of curb appeal projects. According to the “Remodeling Impact Report” from the NATIONAL ASSOCIATION OF REALTORS®, the national median cost of a garage door replacement project is $2,300 and recovers 87% of your investment if you sell your house — one of the highest percentage of recovered costs in the “Report.” 

Thus it is humanly impossible to dodge a falling door. If the spring happens to break when the door is moving up or down somewhere in the middle of travel, as is more likely, then you'll have even less time. Hence it is not prudent to stand or walk beneath a moving garage door. Of course people often do, and the only reason this does not frequently kill people is that springs typically break at the bottom of travel, where they are stressed the most.
The deluxe-model upsell trick: Don't you want the best? Don't you want to protect your family? Galvanized springs may be offered to you at extra expense as "longer lasting". Although bare springs (also called "oil tempered") can develop a light film of rust, the eventual failure is due to fatigue and not corrosion. The use of coated springs (whether galvanized, painted, powder-coated, or surface-converted) is mostly about appearance: the customer likes his new door to look shiny, and the customer doesn't like repair parts that show superficial rust from storage.
If you’re replacing an existing garage door opener in your home, the simplest method for finding the right horsepower is to check the rating of the unit in your garage and get something with equal or higher power. Most homes have single- and double-car sectional garage doors made of aluminum or steel, which is the most affordable type of garage door. These doors are relatively light, so a motor with rating of 1/2 horsepower is more than sufficient. While 1/3 horsepower motors are available, they can wear out faster than those with 1/2 horsepower in such settings, so it’s a good idea to invest a little extra for a more capable garage door opener.
A standard residential door raises 7.5 feet, but since the door goes horizontal this is equivalent to raising the whole door for half that distance, or about 3.75 feet. So if the door weighs, say, 150 lbs, then the energy supplied by the springs is 3.75 * 150, or about 563 foot-pounds. This is like throwing a 50-lb sack of cement up a 11-foot flight of stairs. Or catching a 50-lb sack of cement dropped from 11 feet up.
The low rating on the CS is due to the fact that inwas out of town and my wife called because the garage door wouldn't open. We had repairs to the only other exit, and the CS said because it could be opened manually, it was no emergency. She was stuck in the house for over Sixteen hours. No emergency crew came out. Steve, a tech who came out the first time, fixed the door. It is not his fault CS took their sweet time to help a 45 year customer. I commend Steve. I do NOT have anything good to say about CS.
While a sudden issue is usually easily repaired, a consistent issue that has gone unaddressed for months or years will likely require a total replacement. The problem is that garage doors have a number of heavy, powerful moving parts. If the door is working as it is designed, it can open and close hundreds and hundreds of times without issues. However, if there is even a small issue in the lifting mechanism that repeatedly influences the movement of the door, you will soon find that the damage caused over those hundreds of lifts can’t be fixed.
They sent Doug Fussell out to my house on the day after Christmas! I had only called them three days before! Doug was a premier technician, very thorough and very efficient. I expected him to take two days, since he was replacing two doors and adding openers on each door. He only took the daylight hours of one day! I could not believe how fast he was! In addition, he thoroughly taught me how to use the remote openers. I highly recommend them to anyone!
Stress and lifetime: Calculating the maximal stress in the wire is useful for estimating the lifetime. Using the formula above, the bending stress S in the spring wire is 32*238/(π*0.2253^3) = 212 Kpsi. The spring index C is D/d = 2.23 / 0.225 = 9.88. The Wahl correction factor is Kw = (4C-1)/(4C-4) + 0.615/C = 1.15. The Wahl-corrected stress is Kw * S = 1.15 * 212 Kpsi = 244 Kpsi. This predicts about a 10,000-cycle lifetime, which is the standard "cheap spring" configuration originally installed. Note that while this stress is proportional to the torque being applied, it is also in proportion to the inverse third-power of the wire size. Thus slightly heavier wire sizes (and suitably adjusted D and/or L) radically improve the expected cycle lifetime of the spring.

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.

The "liability" angle: The flip side of "safety issue" is "liability". This is not used to directly sell you something; it is used to demean the cheaper alternative and prod you into buying a more expensive (and profitable) option. For example, you may be pressured into buying a whole new door, when you just need a new spring, by the salesman telling you he can't just replace the spring due to "liability" issues. Since product liability is a big burden on the garage door industry, and so many old doors (and especially automatic openers) are dangerous, this may be a genuine reason to accept a higher price.

For garage doors with windows, try to match the glass style of your house windows to provide a more consistent look. It’s also recommended that you install insulated windows if your garage is heated or air conditioned. If you opt for an uninsulated garage door, make sure it’s made of thick steel – specifically 24-gauge. Thicker steel will help prevent dents.
Screw-drive garage door openers aren't as popular as some other types, but feedback indicates that those that give the Genie Excelerator a try are largely very happy that they did. It's a fast performer, owners say, and the company claims that it can move a door at a rate of up to a foot per second. It's relatively quiet, too -- perhaps not the absolute quietest that you can buy, but certainly quieter than a chain-drive opener, and quieter than older screw-drive openers, users report.
Two of the spring references specifically for the garage-door industry are the APCO Spring Manual by Bill Eichenberger, and the Torsion Spring Rate Book by Clarence Veigel; these give tables of spring sizes and torque constants. Spring engineering principles in general are described in the Handbook of Spring Design published by the Spring Manufacturer's Institute; the formulas allow you to calculate torque constants knowing only the geometry and the Young's modulus of the material. You can also find some brief spring information in standard references like Machinery's Handbook and Marks' Standard Handbook for Mechanical Engineers.
 Nate was very polite and knowledgeable about our garage door dilemma. He was prompt and earlier than the appointed time. He phoned ahead to alert us of his approximate arrival. He assessed the situation and gave us options to choose from. He educated us about our type of garage door and the opener that is typically used with it. He basically did an overall replacement of all moving parts, (spring, cables, bearings etc..). He made sure that the opener wasn’t damaged in any way from the broken spring on the garage door. He was finished within the hour. Everything works great and we are now able to get our vehicles out. When the spring breaks on your garage door, there is no way you can lift this door. It was a little expensive but at least we didn’t have to buy an entire door assembly.read more 

Once you’ve decided it’s time to replace your garage door — whether the result of malfunctions or just seeking to modernize your home’s exteriors — you may be wondering how much a garage door replacement costs. While these numbers are often determined by several factors, including the materials and labor involved, on average, a garage door replacement can cost just over $1,000 but could range from about $300 to over $2,000.
Because your garage door is a major entryway to your home, it is important to keep it in good working order for your own safety, security, and convenience. Choosing the right style and appropriate materials will lessen the amount of repairs that may arise. Additionally, investing in regular maintenance can be cost-effective in the long run. If your garage door is in need of major repair, it is best to call a professional garage door repair company for assistance. Typically, the company will charge for at least one hour for making a service call. However, the benefits of a professional repair job can well outweigh any costs, as a professional can ensure the safety, security, and proper operation of your garage door.
A torsion spring counterbalance system consists of one or two tightly wound up springs on a steel shaft with cable drums at both ends. The entire apparatus mounts on the header wall above the garage door and has three supports: a center bearing plate with a steel or nylon bearing and two end bearing plates at both ends. The springs themselves consist of the steel wire with a stationary cone at one end and a winding cone at the other end. The stationary cone is attached to the center bearing plate. The winding cone consists of holes every 90 degrees for winding the springs and two set screws to secure the springs to the shaft. Steel counterbalance cables run from the roller brackets at the bottom corners of the door to a notch in the cable drums. When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension.[7]
Before carrying out any kind of San Antonio garage door repair, we try and understand the problem at the very first place. After being contacted, our professionals will go and visit your garage personally and find out the actual problem. They are the best people to suggest if the problem can be solved with repairs or if the garage door will need a replacement. Usually if the problem is a minor one, it can be tackled with repairs, but in case of grave issues, complete replacement of the doors is recommended.
Now 13 pounds of force must be respected when backed by many hundreds of foot-pounds of stored energy, waiting to be released. Holding this torque is equivalent to stalling a 3 horsepower DC motor. But holding and turning these handles does not require extraordinary human strength. Note that this maximum tangential force depends only on the weight of the door, and the radius of the drums, and is divided by the number of springs (some designs have only one longer spring, as mine did originally, instead of two shorter ones). Higher or lower lift distances imply more or less turns to wind the spring (and thus a different spring geometry), but not more force on each turn.
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. The product comes with two three-button visor remote controls, a multi-function wall control, as well as a wireless keyless entry system. It comes with a 10-year motor, two-year parts, and one-year accessories warranty.
Regardless of the material, you will likely need to perform some regular maintenance tasks. A garage door professional can examine common problem areas to ensure all are working as they should. Additionally, it is necessary to examine the integrity of the door itself, since your garage can be especially vulnerable to security issues if your door is not structurally sound.
Most situations allow you to replace spring(s) without removing the assembly from the wall, if there is enough clearance in the surrounding garage structure at the ends of shafts. By unbolting the end bearing plates and removing the drums, you can run the springs down to the ends of the shaft to remove and replace the springs. This avoids the balancing act of holding a long, wobbly, heavy shaft while climbing up and down a ladder. This is how the professionals get the job done in a few minutes.
Leveling the door: Before commencing the spring winding, to check that you have the door properly leveled on the cables, considering all the factors above that make this a tricky adjustment, apply the winding cone setscrew lightly to lock the (unwound) spring cone temporarily on the torsion shaft, and momentarily lift the door slightly off the floor. Adjust the drum set as needed to level the door, repeating this slight lift test. Loosen the cone setscrew before winding the spring(s).
Carter door: Garage doors in Florida come with extra bracing on the back and are wind-loaded to protect against hurricanes. The average with is 350 lbs. but some can weigh as much as 800 lbs. It can cost up to $1,000 dollars to replace a steel two-car garage door and if it's made of wood it can cost you up to $5,000 dollars. Some customized doors can be as much as 20 - 30k.
