3 Ways to Cut Your Garage Door Opener Energy Bill

  • 🌱

    Replace the old incandescent garage light with an LED — the opener's light is on for minutes each use and adds up.

  • 💡

    Lubricate the chain, rollers, and hinges annually — a smoothly running door reduces motor strain and energy draw.

  • Disable the courtesy light feature if you don't need it — it accounts for more energy than the motor itself over time.

Startup Surge Information

The motor draws a significant startup surge of about 1,000–1,500W to overcome the door's inertia, then drops to running wattage.
