Why Are the Lights Flickering in My House?

Flickering lights aren’t just a nuisance; they can indicate serious underlying electrical issues that need professional attention. Whether you’re dealing with intermittent flickering or constant lighting issues, it’s important to know the potential causes and when it’s appropriate to address the issue yourself or trust a professional with your lighting repair needs.

In this blog post, our expert electricians at Dean’s Home Services explain common causes of flickering lights, DIY fixes, and when it’s best to seek the help of a qualified electrician.

Common Causes of Flickering Lights

The lights in your home may start to flicker for various reasons, the most common of which include:

Loose or Faulty Lightbulbs

Sometimes, the simplest solution is the correct one: A loose or faulty lightbulb can cause your lights to flicker. Make sure the bulb is screwed in properly and inspect it for signs of damage or defects.

Voltage Fluctuations

Fluctuations in voltage can also cause flickering. Voltage fluctuations typically occur due to high-demand appliances powering on and off, or issues with your electrical service may cause them.

Faulty Light Switches

Malfunctioning light switches can cause flickering as well. If the switch feels warm to the touch or you notice flickering when you tap it, you may want to consider having the switch replaced.

Overloaded Circuits

When too many appliances draw power from a single circuit, it can cause your lights to flicker. This is most noticeable when high-power appliances such as air conditioners or microwaves are in use.

Wiring Issues

Old or damaged wiring can cause flickering lights. This is a more serious issue that may require professional attention to ensure proper functionality and compliance with safety standards and electrical codes.

Electrical Panel Problems

Issues with your electrical panel, such as loose connections or a failing circuit breaker, may cause flickering lights. This is another time when professional intervention is strongly recommended.

DIY Fixes for Flickering Lights

If you’re dealing with flickering lights at home, there are a few troubleshooting techniques you can try before calling in a professional for light repair services:

• Check and tighten lightbulbs: Ensure that all lightbulbs are screwed in securely. Replace any bulbs that appear damaged or defective.
• Replace light switches: If you suspect a faulty light switch, consider replacing it. Be sure to turn off the power at the breaker box before doing any electrical work.
• Reduce load on circuits: Try unplugging some appliances to see if the flickering stops. If it does, you might need to redistribute the load across different circuits or consider adding new circuits.

When To Call a Professional Electrician

While some flickering light issues may be resolved through a simple DIY fix, others may require professional expertise to correct. Here are a few examples of when it’s best to leave the hard work to a trained technician:

• Persistent flickering: If the flickering continues despite your DIY efforts, it’s time to call a professional. Persistent flickering can indicate more serious issues, such as wiring problems or electrical panel malfunctions.
• Burning odor: If you notice a burning smell coming from your lights or switches, turn off the power immediately and contact an electrician. This could be a sign of an electrical fire hazard.
• Hot switches: If your light switches or outlets feel warm to the touch, it’s important to have them inspected by a professional. Overheating components can be dangerous and need prompt attention.
• Outdated wiring: Homes with old or outdated wiring should have regular electrical inspections. An electrician can identify and address any potential issues to prevent flickering lights and other electrical problems.
