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