6 Reasons Why the Lights Dim When Your AC Turns On — An Expert Troubleshooting Guide for Homeowners
If your lights are dimming after your AC turns, it can be due to issues like an overloaded electrical circuit, loose wires, or defective AC components.
Possible Cause #1 — Overloaded Circuit
An overloaded circuit is a common problem. Multiple high-energy devices operating simultaneously on the circuit can use more power than it is capable of handling. The result is a voltage drop, and the lights will flicker. Assess your home’s capacity electrically and move devices to different circuits, if needed.
Possible Cause #2 — Loose Wiring
Inspect the circuit breakers on your panel to see if any have tripped. If so, reset them. Make sure all connections, outlets, and lighting fixtures included are secure and tight. Call a licensed professional if you think there is a more significant problem.
Possible Cause #3 — Faulty AC Parts
If the lights dim when your AC turns on, it could indicate insufficient capacity. Upgrade electrical capacity to ensure enough power is available for all your devices without impacting performance. A licensed professional can assess your requirements and safely perform any upgrades.
Check the electrical connections and circuit breakers to troubleshoot dimmer lights when your AC is on. It could be faulty AC or electrical components that are causing the surge.
Possible Cause #4 — Check Electrical and Circuit Breaker Connections
Inspect the circuit breakers on your panel to see if any have tripped. If so, reset them. Make sure all connections, outlets and lighting fixtures included, are secure and tight. Call a licensed professional if you think there is a larger problem.
Possible Cause #5 — Upgrade Electrical Capacity
