Warning Signs
What Your Home Is Telling You
Safety first. If you see smoke, flames or sparks, smell burning, or someone is hurt, leave the area and call 911. Then call us at 615-357-7797.
Flickering or Dimming Lights
Lights that flicker, dim when the AC starts or buzz can mean loose connections, a failing dimmer or an overloaded circuit.
It may be
- Loose neutral or wire connections
- Overloaded circuits
- Worn switches or dimmers
What to do
- Note when it happens, avoid adding loads to the circuit and book a visit. If it comes with a burning smell, call right away.
Breakers That Keep Tripping
A breaker trips to protect you. Repeated trips usually mean an overload, a short, a ground fault or a worn breaker.
It may be
- Too many devices on one circuit
- A ground fault or short
- A breaker at the end of its life
What to do
- Do not keep resetting it. Unplug what you can and call us to find the cause.
Outlets That Are Warm or Discolored
A warm outlet or a darkened cover plate is a sign of heat from a loose or overloaded connection.
It may be
- Loose terminals
- Overloaded outlets and cords
- Failing receptacles
What to do
- Stop using the outlet, and if it is safe, turn off its breaker. Call us promptly, and call 911 if you see smoke or flames.
Two-Prong or Dead Outlets
Two-prong outlets mean no ground, and dead outlets mean a tripped GFCI, a loose connection or a failed device.
It may be
- No equipment ground
- Tripped GFCI elsewhere on the circuit
- Failed or loose receptacles
What to do
- Check for a tripped GFCI, and if outlets stay dead, book a repair. Ask about grounded replacements.
An Older Home With Original Wiring
Homes built many decades ago may have wiring that was never meant for today’s loads, and some types need a careful look.
It may be
- Knob-and-tube wiring
- Aluminum branch wiring
- Small or crowded panels
What to do
- Schedule a safety inspection so you know exactly what you have and what, if anything, to update.
Electronics and Appliances Dying Early
Power surges can quietly shorten the life of electronics and appliances, even when nothing looks wrong.
It may be
- Storm surges
- Utility switching
- Large appliances cycling
What to do
- Ask about whole-home surge protection plus plug-in strips for sensitive gear.
General information, not a diagnosis. If you smell burning, see smoke or sparks, or feel a shock, leave the area and call 911 first.

Be Ready
What to Do in an Electrical Emergency
If you see fire, smoke or sparks, or someone has been shocked or hurt, leave the area and call 911 first. Do not touch anyone who is still in contact with electricity.
For a total outage, a breaker that will not reset or a hot outlet, stay away from the problem, turn off the main breaker only if it is safe and dry to do so, and call us at 615-357-7797 for help.
What is a GFCI outlet and where do I need one?
A GFCI outlet cuts power quickly if it detects current leaking to ground, which protects you from shock. They are used in kitchens, bathrooms, garages, basements and outdoors, where water may be present.
What is an AFCI breaker?
An arc-fault circuit interrupter detects dangerous arcing in a circuit and shuts it off, which helps reduce fire risk. Many newer homes use AFCI protection in bedrooms and living areas.
Do you handle emergencies?
Yes. If you have an outage, a breaker that will not reset, a hot outlet or storm damage, call 615-357-7797. If you see fire, smoke or sparks, or someone is hurt, leave the area and call 911 first.
Is it safe to use extension cords permanently?
Extension cords are meant for temporary use. If you rely on them, you probably need more outlets or a new circuit, and we can add them.
