Pick what you're noticing. We'll tell you what it usually means, how urgent it is, and what fixes it.

Safety first

Burning Smell, Scorch Marks or Sparks

A burning or hot-plastic smell from an outlet, switch or the panel usually means wiring or a connection is overheating.

If you see smoke, sparks or flames, get everyone out and call 911. If it is safe to reach, switch off the affected breaker or the main. First Choice Electric is not an emergency service; once the area is safe, book a repair visit and we will find and fix the cause.

Outlets or Switches Warm to the Touch

Outlets and switches should not feel warm. Heat points to a loose connection, an overloaded device or, in some 1960s-70s homes, aluminum branch wiring.

Stop using the outlet and unplug what is on it. If you see smoke or scorching, call 911. Then book a visit; do not keep using a hot device.
