Have you noticed your lights flicker when your AC turns on? This phenomenon can be unsettling, but rest assured, it’s often a normal consequence of an AC unit’s initial energy pull. At Green City Heating and Air, we encounter this issue frequently, and we’re here to shed light on why it happens and what you can do about it.

Common Causes of Flickering Lights When The Air Conditioner Turns On

Why Do Lights Flicker When Your AC Turns On?

When your air conditioner kicks on, it requires a surge of electricity to power up its compressor and other components. This surge, known as inrush current, temporarily diverts power within your home’s electrical system. As a result, your lights may briefly flicker. In most cases, this is a normal electrical response and does not indicate a serious problem.  They’re a normal consequence of an AC unit’s initial energy pull.

Is It Normal for Your Lights to Flicker?

Yes, it is completely normal for your lights to flicker when your air conditioner turns on. The inrush current can cause a momentary voltage drop, especially if your electrical system is older or if your AC and lights share the same circuit. AC turning on uses a lot of power, so lights flickering briefly is a normal response. This voltage drop can be more noticeable if there are loose connections or from damaged wires in your electrical setup. If this lighting response happens more frequently, or at times other than the initial turn on, consider calling a professional to check your electrical system and AC units.

What To Do If Your Home Lights Flicker

1. Upgrade Your Electrical System: Consider upgrading your electrical panel or wiring if your home is older or if you frequently experience flickering lights. A modern electrical system can better handle the energy demands of your AC unit.
2. Install a Dedicated Circuit: Having a dedicated circuit for your AC can prevent it from affecting other appliances and lights on the same circuit. This simple installation can reduce flickering and ensure consistent power supply.
3. Check for Loose Connections: Loose connections in your electrical panel or outlets can exacerbate flickering issues. Have a qualified electrician inspect and tighten any loose connections to stabilize your electrical supply.
4. Consult a Professional: If you’re unsure about the cause of persistent flickering or if you suspect damaged wiring, it’s best to consult with a professional electrician. They can conduct a thorough inspection and provide recommendations for repairs or upgrades.
