Residential openers come in three types. Chain drive is the most common and least expensive but a little noisier. Belt drive uses a reinforced rubber belt, runs more quietly and suits attached garages. Wall-mount (jackshaft) openers sit beside the door, free ceiling space and are the quietest, but usually cost the most.
The three types in one minute
Garaga, a door manufacturer, describes the three residential types this way: chain drive pulls a trolley along a rail with a metal chain, belt drive does the same with a steel-reinforced rubber belt, and a wall-mount opener mounts beside the door instead of overhead. LiftMaster's buyer's guide gives the same three families.
Which one is right depends on your door's weight, how close the garage is to bedrooms and how much room you have overhead.
Belt drive or chain drive?
Belt drive
- Steel-reinforced rubber belt
- Runs more quietly
- Recommended for attached garages or rooms above
- Usually costs a bit more than chain
Chain drive
- Metal chain on a rail
- The most common and least expensive type
- A little noisier from metal-on-metal contact and vibration
- LiftMaster calls it built for heavy, frequently used doors
The main trade is noise against price. If a bedroom is next to or above the garage, belt drive is usually the better fit. Our price list covers belt-drive and wall-mount openers.
When a wall-mount opener makes sense
A wall-mount, or jackshaft, opener turns the door's torsion shaft from the side. Garaga says it frees overhead space, suits low headroom or sloped ceilings and requires a torsion spring system. LiftMaster says the design reduces noise and vibration. Garaga calls it the quietest type and usually the most expensive. See wall-mount pros and cons.
How much power does it need?
Garaga says chain and belt openers come in 1/2 HP or 3/4 HP. Most residential doors need 1/2 HP, while heavier doors, such as larger or solid wood ones, call for 3/4 HP. DC-motor openers are rated differently. Garaga says AC motors are rated in horsepower and DC motors in newtons, with 500 N roughly equal to 1/2 HP and 700 N to 3/4 HP. Some brands print a comparison horsepower for DC models, and LiftMaster notes that DC lift capacity is not measured in HP. Read opener horsepower explained before you compare numbers across brands.
What an AC or DC motor means
An AC motor runs at a constant speed. A DC motor starts slowly, speeds up, then slows before it stops. Garaga says the two perform the same, but DC is quieter. DC models are also the ones LiftMaster describes as built for quiet operation, such as its belt-drive 6690L with built-in battery backup. In California, residential openers need a battery backup either way; see the law.
What the types cost with us
Typical prices, with the final price confirmed after we see the door:
- Belt-drive opener with battery backup, installed: $550 to $900
- Wall-mount (jackshaft) opener, installed: $900 to $1,400
- Installation labor only: $150 to $450
Wall-mount units take longer to install, and horsepower, smart features and door size move the price.
Which type fits you
- Bedroom next to or above the garage: belt drive or wall-mount
- Heavy door used all day: check the horsepower or newton rating first
- Low headroom or a sloped ceiling: wall-mount, if the door has torsion springs
- Tightest budget and a detached garage: chain drive is the usual choice
- Not sure: send us a photo of the motor label and the ceiling
Verdict: belt drive suits most attached garages, wall-mount solves space and noise problems, and chain drive is the plain, lower-cost option.
