I. Make sure that your opener actually needs replacing
It is not always that your existing door is out of order, the problems can come from another component. If you hear noisy from your door or you see it slow, it may be broken or loose bracket or roller. You should have a professional engineer installed the door opener because the bottom roller bracket has high tension cables. After replacing the steel rollers with the nylon ones, you will realise that your door is less loud. When the torsion spring above the door is showing a gap, an engineer can help you change it. In another situation, you should also adjust the torsion spring then your door turns on its own.
II. Choose a suitable opener for you
Different type of door is fit for different type of opener. If you have a single door, you just need a one-third or one-half horsepower openers. While the one-half is the most suitable for double door, the third-fourths type is better than for the extra heavy doors. The drive systems must also be chose, these choices depend on personal preference. Although the chain drives are the cheapest, they are the loudest. In contrast, the belt drivers are quietest but the most expensive. And the screw drives require the least maintenance.

If your garage is unfinished, you should cut it until it touch the ceiling with the one-inch lag screws. But you had better use three-inch lag screws for a finished one. Two more sections of angle iron will be used to mount the opener. If the distance between the opener and the ceiling more than 6 inches, you can reduce this distance by attaching an angle brace.
After that, all of the components such as wall button, old phtoelectric sensors and exposed wires must be replaced. Finally, your device can run effectively with the ones as packaged with.
