How to Fix Lights Flickering When AC Turns On?

Is the constant flickering of lights driving you crazy every time your air conditioner kicks in? Don’t worry, you’re not alone. Many homeowners face this issue, and it can be frustrating and even cause concern. In this article, we will explore the common causes of lights flickering when the AC turns on and provide you with practical solutions to fix the problem.

When you notice lights flickering whenever your air conditioner starts, it indicates an underlying electrical problem. This issue can occur due to various factors, and understanding them is the first step towards finding a solution.

Causes of Lights Flickering When AC Turns On

To effectively troubleshoot the problem, let’s look at the potential causes of lights flickering when the AC turns on:

Voltage Fluctuations

Voltage fluctuations can occur when the air conditioner draws a significant amount of power to start up. This sudden surge in power demand can cause lights to flicker momentarily. Voltage fluctuations can be more common in older homes or areas with an unstable power supply.

Overloaded Electrical Circuit

If your air conditioner is connected to an overloaded electrical circuit, it can lead to lights flickering. When the AC starts, it requires a substantial amount of electricity, and if the circuit is already burdened with other high-power appliances, the lights may flicker as a result.

Faulty Wiring

Faulty wiring is another common culprit behind lights flickering when the AC is turned on. Poorly installed or damaged wiring can disrupt the flow of electricity, causing fluctuations that affect the lighting. This issue requires immediate attention as it poses a potential fire hazard.

Loose Connections

Loose electrical connections, especially at the circuit breaker or light switches, can cause intermittent contact and result in lights flickering. Over time, these connections can become loose due to regular usage or improper installation.

Steps to Fix Lights Flickering When AC Turns On

Now that we have identified the possible causes, let’s discuss the steps you can take to fix lights flickering when the AC turns on:

Step 1: Check the Voltage

Start by checking the voltage in your home. Use a voltage meter to measure the voltage levels at different outlets when the AC is turned on. If you notice a significant drop or fluctuation, it indicates a voltage problem. Contact a qualified electrician to assess and address the issue.

Step 2: Ensure Proper Electrical Circuit Capacity

Make sure that the electrical circuit connected to your air conditioner is capable of handling its power requirements. If the circuit is overloaded, consider redistributing the load or consult an electrician to install a dedicated circuit for the AC unit.

Step 3: Examine and Repair Faulty Wiring

If you suspect faulty wiring to be the cause of the flickering lights, it’s crucial to have it inspected and repaired by a licensed electrician. They will identify any damaged or incorrectly installed wiring and rectify the issue to ensure a safe and stable electrical system.

Step 4: Tighten Loose Connections

Inspect the circuit breaker panel, light switches, and outlets for any loose connections. If you find any, turn off the power and carefully tighten the connections. However, if you are unsure or uncomfortable working with electrical connections, it’s best to seek professional assistance.

When to Seek Professional Help

While some minor issues can be resolved by homeowners, it’s important to know when to seek professional help. Consider contacting a qualified electrician in the following situations:

• If you are unsure about the root cause of the problem.
• If you are uncomfortable working with electrical systems.
• If the flickering lights persist even after taking basic troubleshooting steps.
• If you suspect complex electrical issues or need a thorough inspection of your home’s electrical system

Conclusion

Experiencing lights flickering when the AC turns on can be an annoying issue, but it’s not insurmountable. By understanding the causes and following the appropriate steps outlined in this article, you can resolve the problem and enjoy a stable electrical system in your home.
