Common Questions about Garage Doors and Repairs Q: What’s the difference between a chain drive, belt drive and screw drive garage door opener? A: Chain drive garage door openers are inexpensive and very strong and are great for extra-heavy or custom built garage doors, but they’re very loud. Belt- drive garage door openers are much more expensive, but they’re also very strong and are so quiet they’re sometimes considered silent. Screw drive garage door openers fall in between chain and belt drive openers on noise level and cost, and they’re great for extreme environments where it’s very hot or very cold, but they’re not as strong.
