Chain, belt, or screw driven openers used to be the only players in the garage door opener game. But residential jackshaft and direct drive are here to change the market.
Chain models have a chain like a bicycle chain that pushes or pulls a trolley that connects to a track attached to your door. This is the noisiest option on the market, so much so that if your bedroom is situated over the garage, you better hope no one ever gets up earlier than you. This model is a great solution for a detached garage where no one will hear the clanking of the mechanisms of your chain. If this kind of opener is the only one in your price point, the newer models with DC motors and soft start-and-stop tech are much quieter than the traditional.
Belt openers are similar in design to chain-operated openers. Instead of a chain they possess a reinforced belt which manipulates the above mentioned trolley. Belts can be made of fiberglass, polyurethane, or steel reinforced rubber. They have the same reliability as the chain driven model but are significantly quieter. The thing to look out for with belt driven models is that they run around $60 more than their chain driven counterparts.
Screw driven openers use a similar trolley idea, but theirs is threaded into a steel rod. A motor rotates this rod and thus opens the door with very few moving parts. Manufacturers claim that it requires less maintenance than other systems because of the efficiency as well. This model has had problems in climates where there are large temperature swings between summer and winter. It’s been noted to be noisier than the belt-operated opener, but is much speedier than it is opponents.
Jackshaft openers are mounted on the wall beside the garage door. It’s equipped with a 24-v DC motor with pulleys and cables that turn the torsion bar and the raise the door. When the door is reversed the cable tensions is loosened and the door drops. This system is reliable and remains pretty quiet. It’s perfect for garages with abnormal ceilings, either too high or too low, but this model remains one of the most expensive openers.
Direct-drive units are supposed to be the quietest of all it’s opponents. The motor is the only moving part, it traverses along a stationary chain that is embedded in an overhead rail. They’re manufactured in Germany and cost the same as belt-driven openers.
More On the New Wave DC Motors

These models come with varying speeds, enabling soft-start and soft-stop tech and an be equipped with battery backup systems to avoid disaster with power outages.
