"I had an excellent experience with Austin — he called me within 10 minutes of submitting my request on Angi’s List. He arrived at my home within half an hour and got straight to work converting an old cable outlet into a new electrical outlet in my living room. The job was done quickly, cleanly, and exactly as requested. I also asked him to rewire my current outlet so it wouldn’t be controlled by a wall switch, and he handled that with no problem. He was prompt, professional, friendly, and genuinely happy to help — highly recommend!"

"My husband with Alzheimer’s can usually change a light switch but while doing the one in the bathroom couldn’t get it. I put an urgent message on Angie’s list and Terry from Zap electric gave me a call in a few minutes. He came and fixed the switch in 20 minutes. He was knowledgeable and so nice. He gave us a senior discount. A bathroom light is a must and he saved me that day. Please call him of you need any electrical!"

Electrical questions, answered by experts

While most electrical items can be plugged into a GFCI outlet, some appliances with internal or stationary motors, such as refrigerators, vent fans, and fluorescent lighting, can cause nuisance tripping. This happens because they experience a small, normal amount of current leakage, which can cause the GFCI to trip even when the appliance is working correctly. Although this is not a safety hazard, it can be inconvenient and may cause the GFCI outlet to wear out faster. For this reason, it is often better to plug these types of appliances into a standard outlet. Additionally, electrical circuits over 100 feet long can sometimes cause tripping. Some appliances, like hair dryers, have their own built-in GFCI protection, so connecting them to a standard outlet is fine.

Upgrading your electrical panel is often worth the cost for safety, improved electrical performance, and potential long-term savings. A primary benefit is preventing electrical fires and other hazards from a malfunctioning panel, ensuring your household's safety. An upgraded panel also provides a steady flow of electricity, eliminating issues like flickering lights and frequently tripped breakers. It allows you to connect additional appliances without overloading the system, which is especially beneficial for older homes with 100-amp service that are prone to overheating. If you run large appliances like central air conditioning, heating systems, hot tubs, or saunas, you might consider upgrading to a 300- or 400-amp service to meet the higher electrical demand. Furthermore, an upgrade can lead to long-term savings on energy bills and potentially lower insurance costs.

A C-wire connects your thermostat to your household heating and cooling system to provide continuous 24V power. The furnace's transformer converts household electrical current into this low-voltage power to operate the HVAC system's circuitry. In most configurations, the C-wire connects to the terminals labeled "C" on both the furnace's low-voltage terminal block and the thermostat. In some cases, if a dedicated C terminal is unavailable, the C-wire can be connected to the "G" (fan) terminal at the furnace.

Yes, many professionals offer wiring upgrades as part of their services, including upgrades to support VoIP, fiber optic, or high-speed internet connections. It is recommended to confirm the specifics with your contractor.

No. Blue wires and black wires are different. Even though both are used as hot wires, they serve different functions. Black wires are far more common in residential properties. They are always hot, can be positive or negative, and usually carry electricity from a power source to an outlet. Blue wires have a specialized usage in residential properties, generally as traveler wires, and are more common in commercial properties.
