3 Types of Residential Garage Door Openers
Chain Drive: Chain driven garage door openers are the most common type of opener. They use a chain to pull or push a trolley that moves the garage door up and down. They are affordable and extremely reliable. Because chain drive openers can be a bit noisy, they are often best suited for a detached garage. For example, see LiftMaster 8165.
Belt Drive: Belt driven garage door openers use a belt instead of a chain to move the garage door. Belt driven openers are much quieter compared to chain driven openers, making them ideal for attached garages, but are a bit more expensive then chain driven openers. For example, see LiftMaster 8557.
Screw Drive: This type of garage door opener rotates a threaded steel rod to move the trolley that opens or closes the door. There are less components, resulting in less maintenance over its lifetime, but they can be a bit noisier than a belt drive. For example, see LiftMaster 3240.
