It is really annoying to get out of the car in the pouring rain or snow just to open the garage door and so the automatic garage door opener is invented. An automatic garage door opener is a motorized device that helps in automatically opening and closing the garage door. But before you rush to buy one, here are some info on the types of automatic garage door opener.

Drive System

• Screw-drive system: The mechanism that operates the door slides along a threaded shaft made of steel. Maintenance is simple and the device is housed on the ceiling.
• Chain-drive system: The garage door moves up and down along by means of a metal chain device. This is the most popular because it is cheap. The downside of this device is that it is noisy when in operation.
• Belt-drive system: Makes the use of a rubber belt to operate the garage opener. This is the most expensive of all the automatic garage door openers.
• Computer-controlled system: Useful for garages with limited headspace because the device is installed on top of the garage door.

Aside from choosing the best drive system to operate the automatic garage door opener, you also have to consider other factors. One is the power of the motor that drives the system specially for those that will be used to maneuver double doors. The doors should operated with minimum noise. Second is the speed of operation.

This feature is mandatory fro all types of garage door openers.
