Why do my lights flicker?
Occasional flicker when a big appliance starts (AC, dryer) is usually normal — a brief voltage dip. Lights that flicker constantly, in one room, or across the whole house are a connection problem until proven otherwise: a loose wire, a failing breaker, or a deteriorating service connection. Whole-house flicker is the one to take seriously — a loose service connection can arc and overheat.
Likely causes
- Failing bulb or LED driver — One flickering fixture is almost always the bulb or its driver, not your wiring.
- Loose connection — A loose wire nut, outlet, or switch connection in one room — flicker that changes when you tap the switch.
- Overloaded circuit — Flicker synced with a space heater, microwave, or hair dryer on the same circuit.
- Service or panel problem — Whole-house flicker, worse in wind or weather — utility connection or main panel. This one is a fire risk.
What you can check yourself
- Narrow it down: one bulb, one room, or the whole house? The pattern is most of the diagnosis.
- Swap the bulb first if it's a single fixture — cheap certainty.
- Note whether flicker syncs with an appliance starting, and tell the electrician — it saves troubleshooting time.
Typical cost

When to call a pro
Whole-house flickering, flicker plus buzzing or a burning smell at the panel, or lights that brighten as others dim — call an electrician promptly, and mention 'possible lost neutral'; they'll understand the urgency.
