Why Are My Lights Flickering? A Guide for East Nashville Homeowners

Flickering lights can mean anything from a loose bulb to a real electrical safety issue — and in East Nashville's older homes, the cause is often tied to the age of the wiring itself.

Common Causes

• A loose bulb or fixture connection — the simplest and least concerning cause
• A loose wire connection at the switch, outlet, or panel — a genuine fire risk that needs attention
• An overloaded circuit, especially when the flicker happens as another appliance turns on
• A failing breaker that isn't providing consistent power delivery
• Utility-side voltage fluctuations, which affect a whole block rather than a single home
• Aging wiring, including knob-and-tube or degraded connections common in pre-1950 East Nashville homes

When It's an Emergency

Flickering paired with a burning smell, warm outlets or switches, or visible scorching is not a wait-and-see situation. Shut off the affected circuit if it's safe to do so and call an electrician right away.

Older Wiring and Flickering Lights

In East Nashville's historic homes, flickering is often traced to degraded connections in knob-and-tube wiring or an undersized panel that's been carrying more load than it was designed for as households have added modern appliances and electronics over the decades. A licensed electrician can trace the actual circuit and identify the real cause instead of guessing.

What We Check

We test the affected circuit, inspect the panel and breaker condition, check connections at the switch and outlets involved, and rule out whether the issue is isolated to one circuit or affects the whole home.

Frequently Asked Questions

Why do my lights flicker when the AC or a large appliance turns on?

This usually points to a shared circuit carrying more load than it comfortably handles, or a loose connection reacting to the sudden draw.

Is flickering always dangerous?

Not always — a loose bulb is harmless. But flickering tied to a loose wire connection or an overloaded circuit is a real fire risk and worth having checked.

Could it be my utility company's fault?

Sometimes. Voltage fluctuations on the utility side usually affect multiple homes on the same block, not just one house.
