There are three main types of garage door openers, each with its own range of features, advantages, and disadvantages. Cable-pulled openers are inexpensive to install, but have limited capacity to lift heavy doors. Chain-driven openers are much sturdier than cable-pulled openers yet still cheaper than most screw- or belt-driven models. Screw and belt-driven openers are the sturdiest and easiest to install, but they also come with the highest price tags and require regular maintenance and replacement of worn parts.
