Frequently Asked Questions

The most frequent issues homeowners encounter include tripped circuit breakers, dead outlets (often due to a tripped GFCI), flickering lights, and light bulbs that burn out too quickly. Most of these are signs of circuit overloads or loose connections that should be addressed promptly.

An electrical emergency involves an immediate risk of fire or shock. If you see smoke, smell burning plastic/ozone, see sparks from a panel, or have a complete power loss to essential medical equipment, shut off the main breaker if safe to do so and call an electrician immediately.

Flickering is often caused by a loose bulb or a faulty fixture. However, if multiple lights flicker when a large appliance (like the AC or vacuum) turns on, it usually indicates a circuit overload or a problem with the main service wire coming into the house.

You should test the “Test” and “Reset” buttons on your GFCI outlets (the ones with buttons found in kitchens and bathrooms) at least once a month. These outlets are designed to protect you from fatal shocks, so ensuring the internal trip mechanism works is a vital safety habit.

A breaker trips when the circuit is drawing more electricity than it can safely handle. This is usually caused by plugging too many high-wattage appliances into one area. If it trips with only one item plugged in, you may have a “short circuit” or a ground fault.

A spike in electricity costs often points to aging appliances that are working harder to stay cool (like refrigerators), a water heater with a faulty heating element, or “phantom loads”—devices that draw power even when turned off.
