Flickering lights in an Orlando home can have several possible causes. A loose bulb or incompatible LED dimmer may be responsible for a single flickering light, while widespread flickering can point to an issue with a circuit, electrical connection, service equipment, or utility supply.
The pattern matters.
If only one light flickers occasionally, the problem may be relatively simple. If lights throughout your home flicker, become unusually bright or dim, or change when major appliances turn on, it’s worth having the electrical system evaluated.
Check the Light Bulb First
If one light is flickering, start with the bulb.
A bulb that isn’t seated correctly can flicker because it isn’t making consistent contact with the socket. LED bulbs can also flicker when they’re incompatible with certain dimmer switches.
If replacing or properly seating the bulb solves the problem, you may not have an electrical system issue.
Can Loose Connections Cause Flickering Lights?
Yes. Loose electrical connections can cause intermittent electrical problems.
Depending on where the connection is located, you might see flickering in one fixture, several lights on a circuit, or multiple areas of the home.
Connections can deteriorate over time, and heat or corrosion can contribute to the problem.
Because diagnosing electrical connections can require professional testing, persistent flickering should be evaluated by a qualified electrician.
Why Do My Lights Flicker When the AC Turns On?
Air conditioning systems can place a significant electrical load on a home, particularly when a compressor or other motor starts.
A brief, minor change in lighting when a large motor starts may not indicate a serious electrical problem.
However, pronounced or persistent dimming can indicate an electrical issue and should be evaluated.
An electrician can determine whether the problem involves the circuit, electrical service, connections, or another component.
What If Lights Throughout the House Are Flickering?
If multiple rooms are affected at the same time, the issue may be located farther upstream in the electrical system.
Potential causes include an electrical panel problem, service connection issue, loose neutral, or utility-side problem.
If your lights become dramatically brighter or dimmer, especially when appliances turn on or off, contact an electrician promptly. Significant voltage fluctuations can damage electrical equipment.
If your neighbors are experiencing the same issue, the utility may be the source. If the problem is isolated to your home, an electrician can investigate your electrical system.
Can Florida Storms Cause Flickering Lights?
Thunderstorms and lightning can cause temporary electrical fluctuations and utility disturbances.
If flickering begins during a storm and stops afterward, it may have been caused by a temporary utility issue.
If flickering continues after the storm, however, don’t assume it will resolve on its own. Have the problem evaluated if it persists.
Does Flickering Mean You Need a New Electrical Panel?
Not necessarily.
Flickering lights can result from something as simple as a bulb or dimmer, while widespread flickering can indicate a problem with wiring, connections, service equipment, or the utility supply.
An electrical panel upgrade may be appropriate if the panel is outdated, damaged, or inadequate for the home’s electrical demand. But the cause of the flickering should be identified first.
When Should You Call an Electrician?
Contact an electrician if:
- Multiple lights flicker at the same time
- Lights become unusually bright or dim
- Flickering is persistent
- Flickering occurs when major appliances start
- You hear buzzing or crackling
- You smell burning
- Outlets or switches feel hot
- Flickering began after a storm
- Circuit breakers are also tripping
These signs can indicate an electrical problem that requires professional troubleshooting.
