There are a few things you'll want to consider when selecting a garage door opener.   The most important factors are the weight of your door and the type of motor.  You'll also want to make sure the opener is compatible with your door's system. The weight of your door is important because you'll need an opener with enough power to lift it. You can find this information on the garage door opener's specifications sheet.   The type of motor is also important – choose an AC motor if you have an insulated door, or a DC motor for a non-insulated door.   In addition, make sure the opener is compatible with your garage door's system by checking the manufacturer's list of approved openers. Finally, think about what cool, extra features *you* want! Modern garage door openers can have advanced features such as WIFI, battery back up, LED lighting, cameras, keypads, and remotes.
