Have you noticed the lights in your home flickering? While it might seem like a minor annoyance, flickering lights can sometimes signal deeper electrical issues. At Aztec Electric, we’ve helped countless Austin homeowners diagnose and fix lighting problems—and we know the difference between a simple fix and a serious concern. Here’s what you need to know about the causes and solutions for flickering lights.
Common Causes of Flickering Lights
Loose or Faulty Bulbs
The simplest explanation is often the right one. A bulb that’s not screwed in tightly or one that’s reaching the end of its life may flicker.
Incompatible Dimmer Switches
Not all bulbs work with every dimmer. For example, pairing standard LEDs with an old dimmer switch can cause constant flickering.
Overloaded Circuits
If lights flicker when large appliances (like a washing machine or HVAC system) kick on, your circuit may be overloaded. This is especially common in older homes with limited electrical capacity.
Loose Wiring
Loose connections at outlets, switches, or within your electrical panel can cause intermittent flickering. This is more than an inconvenience—it’s a fire hazard.
Voltage Fluctuations
If multiple lights flicker across the house, you may be experiencing voltage fluctuations in your electrical system. This could be due to a failing panel or issues with your utility service.
Solutions for Flickering Lights
Check and Replace Bulbs
Start simple: make sure bulbs are securely screwed in, and replace any that appear damaged or burned out.
Upgrade Dimmers and Bulbs
If you’re using dimmers, make sure they’re compatible with your bulbs—especially LEDs. Installing modern dimmers can solve many flickering issues.
Redistribute Power Usage
Avoid plugging too many high-demand appliances into the same circuit. If overloads continue, consider having an electrician add dedicated circuits for major appliances.
Have Wiring Inspected
Because loose wiring is a serious safety risk, it’s best to have a licensed electrician check your outlets, switches, and panel if flickering persists.
Install Whole-Home Surge Protection
Austin storms and power surges can cause lights to flicker. A whole-home surge protector not only reduces flickering but also shields sensitive electronics from damage.
When to Call an Electrician
If flickering happens regularly, affects multiple rooms, or is accompanied by burning smells, warm outlets, or frequent breaker trips, don’t wait—call a professional. These are red flags that point to dangerous wiring issues.

Flickering lights aren’t just a nuisance; they’re your home’s way of telling you something might be wrong. By identifying the cause early and taking corrective action, you’ll ensure your home stays safe, efficient, and well-lit.
