Answer first
Brief dimming when a large load starts can be normal; rhythmic flicker, multi-room flicker, or flicker with buzzing is a warning to investigate.
01
Definition
What is this?
Light flicker is a visible symptom of voltage variation, loose connections, failing devices, or utility-side events.
02
When to use
When does this apply?
Call for diagnosis when flicker is frequent, affects many rooms, accompanies burning smell, or started after electrical work.
03
Failure modes
What goes wrong?
Ignoring flicker that tracks with heat or rain. Tightening random wirenuts without finding the fault. Assuming every flicker is the utility.
04
Proof
Why trust this guidance?
Hurst troubleshoots flicker across Danville-area homes — from loose neutrals to failing panels — with testing, not guesswork.
05
Action
What should you do next?
Note which rooms and which appliances coincide with flicker, then schedule electrical troubleshooting.

FAQ
Is LED flicker different?

Yes. We help separate utility events from premises wiring.
Is it an emergency?
Smell, heat, sparking, or partial outage — treat as urgent.
