Belt Drive
The quieter sibling — worth the difference for attached garages.

- Cost: at equal horsepower and features, chain models undercut belts — the savings can fund nylon rollers or a keypad.
- Durability: a metal chain doesn't mind heat, cold, dust or decades. With basic lube it outlasts nearly everything around it.
- Strength reputation: chains earned the heavy-door reputation honestly, though modern belts have closed the gap for residential weights.
- Simplicity: every technician in America can service one, and parts are everywhere.
Its Honest Weaknesses
- Noise: the defining trade-off — metal links over a sprocket, resonating through the rail into the framing. Detached garage? Irrelevant. Bedroom above? Deal-breaker.
- Maintenance isn't optional: a neglected chain goes slack, slaps, and accelerates gear wear. (It's five minutes a year. Do the five minutes.)
- Vibration: more of it reaches the door and house than with belt or wall-mount drives.
Common Chain-Drive Repairs We Do
Stripped main drive gears (the classic hum-but-no-motion failure), chain tension and sprocket wear, trolley replacement, and capacitors on older AC units. Most are same-visit fixes with truck-stocked parts — see opener repair for the full symptom table.
Common questions
Frequently Asked Questions
Why choose chain over belt today?
Three good reasons: the garage is detached (nobody hears it), the budget is doing double duty (chain models cost less at equal feature levels), or the door is heavy and cycled hard (chains shrug off abuse and heat with simple maintenance). If none of those apply, the belt-drive page makes the case for spending slightly more.
What maintenance does a chain drive need?
Two small chores: lubrication of the chain (opener-rated lube, sparingly — over-greasing collects Las Vegas dust) about once a year, and a tension check, since a slack chain slaps the rail and a tight one wears the sprocket. Both get done automatically in a ProTech tune-up.
My chain drive got much louder lately. What changed?
Something's asking for attention: chain gone slack, drive gear wearing (listen for grinding), dry chain, or — most commonly — the door itself got heavier to lift through spring fatigue, so the whole system strains. Louder-than-usual is a diagnostic symptom, not a personality trait; worth a visit before it becomes a gear kit or worse.
Can I make my existing chain drive quieter?
Meaningfully, yes: proper chain tension and lubrication, isolating the mounting with rubber pads, nylon rollers on the door, and correct balance so the motor isn't straining. It won't become a belt drive, but 'wakes the baby' can usually become 'background noise.'
