Why Your Lights Flicker More In Cold Weather

If your lights flicker during the winter, you’re not alone. Cold temperatures often bring heavier electrical loads from heating systems and space heaters, which can cause brief drops in voltage. Here’s what could be happening:

1. **Utility fluctuations.** When many homes draw extra power, voltage can dip temporarily.

2. **Loose wiring connections.** Cold weather can contract metals and loosen terminals.

3. **Old electrical panels.** Older panels may struggle to handle high winter loads.

4. **Heavy appliance use.** Running multiple heaters or dryers on one circuit can cause flickering.

If lights flicker across multiple rooms or throughout the building, it could point to a larger issue—possibly even from the utility transformer outside. Have a professional inspect your system for safety and stability.
