Why Are My Lights Flickering or Dimming?

Noticing your lights flickering or dimming unexpectedly? At Malco Electric, we help Austin homeowners diagnose and solve these common electrical issues to keep your home safe and comfortable.

What Causes Lights to Flicker or Dim?

1. Loose or Faulty Bulbs

Before assuming it’s a big problem, check if your light bulbs are properly tightened or if they need replacing. Loose or failing bulbs are a quick and simple fix.

2. Faulty Light Switches or Fixtures

Worn-out switches or aging light fixtures can cause intermittent flickering. If replacing the bulb doesn’t help, the issue may be with the fixture itself. Our residential electrical services include fixture and switch troubleshooting.

3. Overloaded Circuits

If your lights flicker when large appliances turn on (like your AC or microwave), it could mean your circuit is overloaded. This indicates your electrical system might need an upgrade or redistribution of load.

4. Loose Wiring Connections

Loose or damaged wiring is a serious safety hazard and a common cause of persistent flickering. These issues can lead to overheating and even fires if not addressed promptly. Contact us immediately if you suspect wiring problems.

Why You Shouldn’t Ignore Flickering Lights

Persistent flickering is more than just annoying — it can be a sign of underlying electrical hazards. Addressing it early helps protect your home and avoid costly repairs later on.
