Understanding Flickering Lights When AC Turns On: 1 Minute to Learn About AC and Electrical Issues

Do your lights flicker when the AC comes on? This common phenomenon can be frustrating and a little worrying. Let’s delve into the possible reasons and solutions.

When your air conditioning unit starts, it draws a significant amount of power. This sudden demand can cause a temporary drop in voltage, leading to flickering lights. If you’re in an older home, the wiring may not be equipped to handle the load.

Possible Causes of Flickering Lights:

1. **Voltage Drop:** The AC compressor draws more power compared to other household appliances. This surge can cause a drop in voltage.

2. **Wiring Issues:** If the wiring in your home is outdated or damaged, it may not distribute power effectively, causing lights to flicker during high-demand times.

3. **Circuit Overload:** Too many appliances on a single circuit can lead to overload and flickering. Consider checking the load on circuits.

Solutions to Prevent Flickering Lights:

1. **Upgrade Wiring:** If you have an older home, consider upgrading your electrical system to meet current demands.

2. **Use Dedicated Circuits:** Connecting your AC unit to a dedicated circuit can help prevent flickering lights when the system activates.

3. **Consult an Electrician:** For a professional assessment, it’s always best to consult with a licensed electrician to diagnose the issue effectively.
