If your garage is attached to a bedroom or bonus room, the type of opener drive you choose makes the difference between hearing it open at 6 a.m. or not. Here's the no-spin comparison from a shop that installs all three in Chattanooga every week.
Metal chain pulls the trolley along the rail. Cheapest ($445–$545 installed). Most durable. Loudest—roughly 60–65 dB at the bedroom wall. Best for detached garages or homes where the garage doesn't share a wall with a sleeping room.
Reinforced rubber belt instead of chain. Roughly 40–45 dB—about as loud as a quiet conversation. Slightly more expensive ($585–$745 installed). Lifespan is now equal to chain on modern LiftMaster and Chamberlain models. Right answer for any garage sharing a wall with living space.
Mounts beside the door on the torsion shaft—no overhead motor or rail. Frees ceiling for storage or a car lift. Very quiet. Premium price ($895–$1,195 installed). Requires torsion springs (not extension). Our most-requested opener for high-end Chattanooga garages.
