What Causes Flickering Lights?

What Can Cause Flickering Lights In A House?

Flickering lights can be an annoying and sometimes unsettling issue in any home. Whether it’s a single light bulb or multiple lights flashing throughout the house, understanding the root cause of electrical problems is essential for maintaining a safe and comfortable living environment.

McCullough Air Conditioning, Plumbing & Electrical is here for homeowners in Niceville and surrounding areas. In this blog, we’ll explore common reasons for blinking lights and what can cause them in your house.

1. Loose Bulbs Or Fixtures

One of the most straightforward reasons for flickering lights is a loose bulb or fixture. If a light bulb isn’t screwed in tightly, it may result in an unstable connection, leading to flashing. To fix this issue, ensure all bulbs are tightly screwed in and check fixtures for any loose wiring.

2. Faulty Light Switches

Another common cause of flickering lights is a faulty light switch. Over time, the internal components of a switch can wear out, leading to poor connections. If you notice that your lights flicker when you toggle a specific switch, it might be time to replace it.

3. Voltage Fluctuations

Voltage fluctuations can also be responsible for blinking lights. Inconsistent voltage levels can cause lights to dim or flash intermittently. If you notice low-voltage lights flickering frequently, it could be due to fluctuations in the electrical supply. This issue often requires the expertise of a licensed electrician, like the team here at McCullough.

4. Overloaded Circuits

If the lights flicker when you plug something in, it could be a sign of an overloaded circuit. High-demand appliances like air conditioners, microwaves or computers draw significant amounts of power. The electrical demand from these electronics can cause temporary voltage drops and lead to blinking lights.

5. Electrical Panel Issues

Loose connections, corroded wires or malfunctioning circuit breakers can disrupt the flow of electricity, causing lights to flash. An aging or overloaded electrical panel may need to be serviced by our team to ensure a steady power supply.

6. External Factors

External factors such as weather conditions and issues with the utility company’s equipment can also affect your home’s electrical supply. These interruptions can lead to blinking lights. For instance, strong winds, storms or damage to power lines can cause temporary fluctuations in power.

7. Worn Out Wiring

Homes with outdated electrical systems may experience frequent flickering due to worn-out insulation or corroded wires. If your house is old and you encounter persistent issues, it might be time to have one of our electricians inspect the wiring. Depending on the state of the wires, we’ll recommend necessary upgrades or repairs to solve the problem.

Preventive Measures And Solutions

To prevent and address flickering lights, consider the following steps:

  • Regular maintenance — Regularly inspect and maintain your light fixtures, switches and electrical panel to ensure they are in good working condition.
  • Professional inspections — Schedule periodic inspections by a licensed electrician to identify and rectify any underlying electrical issues.
  • Avoid overloading circuits — Be mindful of the electrical load on each circuit and distribute high-demand appliances across different circuits to prevent overloading.
  • Upgrade wiring — If you live in an older home, consider upgrading the wiring to meet modern safety standards.

By following these preventive measures and addressing the common causes of flashing lights, you can ensure a stable and safe lighting environment in your home. If you encounter persistent issues, don’t hesitate to contact the McCullough team!
