Garage Door Opener Repair & Installation in Sunnyvale, CA
A humming motor, a door that reverses halfway, a remote nothing answers — three faults with one appearance. We diagnose and repair all major brands and install modern Wi-Fi openers with the battery backup California requires on new installations.
Why Sunnyvale homes need opener repair done right
The Sunnyvale opener story is usually a healthy motor doing too much work. An opener that survived a remodel is frequently lifting a heavier door than it was chosen for, or dragging one that binds in a reframed opening — it runs hot, trips its force settings and gets replaced, and the new one inherits the same job. We measure the door's balance before condemning any unit. On Eichler streets, a wide door out of true does the same thing for a different reason.
The opener is the motor and brain of the door — and California law (SB-969) now requires battery backup on newly installed openers. We diagnose and repair every major brand, from a slipped drive gear or bad logic board to misaligned safety sensors, and install modern Wi-Fi openers with myQ smartphone control and battery backup that keeps you covered during a power outage.

What we service in Sunnyvale
What to expect on your Sunnyvale visit
- 1
Diagnose motor vs. door
Half of 'opener' problems are actually a spring, cable or sensor issue overworking the motor. We confirm the real cause before recommending a repair or replacement.
- 2
Repair or right-size a new unit
We repair boards, gears and sensors where it makes sense, or recommend the correct horsepower drive (chain, belt, or quiet wall-mount) for your door's weight.
- 3
Smart + battery-backup setup
New installs include Wi-Fi (myQ) pairing and a code-compliant battery backup, so the door still opens when the power is out.
- 4
Safety calibration
We set travel limits and closing force, align the photo-eyes, and test auto-reverse against an obstruction so the door meets safety standards.
