Electrical Troubleshooting and Repair in Greater Orlando

Flickering lights are typically caused by a loose connection, a dimmer-and-LED mismatch, an overloaded circuit, failing switches, or voltage fluctuations from the utility, and fixes range from simple bulb or device changes to professional wiring repair. The most common everyday cause is a loose bulb or using non‑dimmable LEDs on a dimmer, which makes LEDs pulse. Our electricians often see that persistent, room-wide flicker points to a weak connection in a switch, light box, or panel, while whole‑home dimming under load hints at service or utility voltage issues. A loose connection can arc, creating heat, so don’t ignore frequent or worsening flicker. Technicians serving the Windermere area diagnose these issues with meter-based testing and a safety-first approach.

Try these quick checks before you call:

• Tighten the bulb and match bulb type to the switch (dimmer-compatible LEDs for dimmers).
• Swap in a new bulb and, if possible, temporarily bypass the dimmer with a standard switch.
• Note if flicker coincides with large appliances starting, or if multiple rooms dim together.
• Call a pro if you notice buzzing, warmth at a switch, a burning odor, or repeated breaker trips.

If lights dim across the house or you detect heat or odor at a switch or panel, turn off the circuit and schedule an electrician.
