Even the most energetic people dread getting out of their cars to open the garage door. This aggravation is made a lot easier with an automatic garage door opener. Garage door openers operate electronically or by battery, and can be operated from your car or elsewhere with a remote control. There are three basic types of garage door openers - chain-driven, belt-driven and screw-driven. Before you mount a door opener make sure the garage door is lubricated and working properly. If you can't open and close the door by hand don't install the opener until you fix the door. Faulty automatic garage doors can be dangerous and even cause death, so ensure that the garage door opener is installed and working properly. The garage door should also have an electronic eye, or sensor, so when objects are detected, the door will stop closing or reverse. Also, install a wall switch that's unreachable by children and keep the remote in a safe place. Garage door openers come in various horsepower and start at about $400 online.
