Flickering lights? We diagnose and fix the cause

Flickering lights are more than an annoyance — they can signal a loose connection, an overloaded circuit, or a wiring problem that needs attention. Precision Power Services diagnoses the root cause and repairs it safely. Serving Rutland and central Vermont with free estimates.

Causes

Why your lights flicker

Flickering lights can have several causes. A loose bulb is the simplest — try tightening or replacing it first. But if the flickering persists, or affects multiple lights, the cause is usually in the wiring or the circuit.

A loose connection in a switch, outlet, or junction box can cause flickering. Loose connections create resistance, which generates heat and can lead to arcing — a fire hazard. These need professional repair.

If lights dim when an appliance turns on (like an AC unit or refrigerator), the circuit may be overloaded or the neutral connection may be compromised. This is common in older homes with smaller services.

If your whole house flickers or dims, the issue may be at the panel, the service entrance, or even the utility side. This needs professional diagnosis.

Common causes of flickering

  • Loose bulb or fixture
  • Loose connection in wiring
  • Overloaded circuit
  • Failing switch or dimmer
  • Aging or damaged wiring
  • Neutral connection issue
  • Service entrance problem
  • Utility voltage fluctuation
Repairs

How we fix flickering lights

Connection tightening

We inspect and tighten connections at switches, outlets, and junction boxes to eliminate resistance and arcing.

Circuit load balancing

If flickering is caused by overload, we redistribute loads or add new circuits to prevent voltage drops.

Switch and dimmer replacement

Failing switches and dimmers cause flickering. We replace them with quality, code-compliant parts.

Wiring repair

Damaged or aging wiring can cause flickering and is a fire hazard. We repair or replace affected wiring.

Panel inspection

If flickering affects the whole house, we inspect the panel and service entrance for loose connections or damage.

Whole-home surge protection

Voltage fluctuations can cause flickering. A whole-home surge protector stabilizes and protects your system.

Safety

When flickering is an emergency

If lights flicker accompanied by a burning smell, buzzing from the panel, or sparks from an outlet, turn off the breaker and call immediately. These are signs of arcing or overheating.

If flickering started after a storm, flooding, or any damage to your home, call for an inspection before using the affected circuits.

Flickering that affects only one light is usually minor. Flickering that affects multiple lights or the whole house needs professional attention. Call (802) 417-0587.

Warning signs

  • Flickering with burning smell
  • Buzzing from panel
  • Sparks from outlets
  • Whole-house flickering
  • Flickering after storm or flooding
  • Lights dim when appliances start
