"Great experience from start to finish. My wife and I needed to have 2 ceiling fans and light kits installed. The work was scheduled quickly and TFC Electrical Services was even able to do the job earlier than expected. Tom and Ralph arrived as scheduled, on time and we were given a fair price quote. They had to install electrical wiring and box in our bedroom ceiling prior to installing the fan and light. They took the time to protect our furniture and floors by covering everything with protective tarps. Additionally, the installed a fan and light kit in an adjacent staircase. The concern and respect that they showed for our home was admirable and appreciated. The installations were neat, clean and expertly completed. They completed all the work in about 3 hours. TFC Electrical Services should be a model for “ALL” other electrical contractors. Any future electrical work in my home will be offered to this company. Thank you Theresa, Tom and Ralph."

"From start to finish, Best Quality Electric delivered an exceptional, white-glove experience. The process began with a dedicated consultation that was educational, detailed, and thoughtfully planned—setting a clear vision before any work even began. The following day, the team arrived precisely on time and immediately demonstrated a level of professionalism that is rare to find. Shoe protection was used, and every floor and piece of furniture was carefully covered. Their respect for the home was as impressive as their craftsmanship. Watching the two electricians work was remarkable. They operated in perfect sequence, anticipating each other’s next step, covering every single detail with precision. Not one question went unanswered—each was met with patience, clarity, and deep expertise that inspired complete confidence. Best Quality Electric truly lives up to its name. This is not just electrical work—it’s a refined, high-standard service experience. Bold, meticulous Toptier work!"

"PKJ Electrical is the most professional electrician's I have ever hired. They were on time, courteous and very knowledgeable. They replaced my breaker box. I have never before seen the wires so neat and organized as I did after he was finished with my job. I will only hire PKJ for all of my future electrical needs. Thank you again for such a wonderful experience."

Electrical questions, answered by experts

No, not all thermostats require a C-wire. Older manual and programmable thermostats typically do not need one. While many smart thermostats do require a C-wire to function correctly, some models can operate without one, often at the expense of certain features. A C-wire provides a constant source of power, which enables the thermostat to stay connected to Wi-Fi and keep its display screen lit on-demand. If you are upgrading from an older thermostat to a smart model that requires a C-wire, you may need to install one first for it to work as intended.

When installing an outdoor outlet, it's important to proceed with caution. Unless you have the necessary training and licensure, it's not recommended to attempt this DIY. First, choose a suitable location. Make sure that the area can accommodate the outlet without overloading the circuit. You'll also need to ensure that your project complies with building codes. Next, turn off the power to the circuit, then install and wire the outlet according to the manufacturer's instructions. Once the outlet is in place, test it. Lastly, be sure to use a cover that will protect it from moisture and other weather-related damage.

GFCI outlets generally need to be replaced every 7 to 15 years, though some may fail in as little as 5 years, depending on usage. It is important to test them regularly. Signs that a GFCI outlet is failing or has reached the end of its lifespan include: no power coming from the outlet, the outlet not resetting when the 'reset' button is pressed, or the outlet not tripping when the 'test' button is pressed. If you notice any of these issues, it is time to replace the outlet, and it's best to contact an electrician to do so.

Common signs of faulty electrical wiring include frequent circuit breaker trips, flickering or dimming lights, burning smells near an outlet, buzzing or humming sounds, electrical shocks or tingles when handling outlets of appliances, and hot or discolored outlet switches. If you notice one or more of these signs, hire a licensed electrician for an average cost of $50 to $100 per hour to diagnose and make necessary repairs.

Although homeowners can turn off a breaker, it’s vital to follow safety precautions when doing so to prevent serious and potentially fatal injuries. For instance, you want to ensure there is no water on the floor when you touch the breaker and wear protective gear such as safety glasses. Anytime you deal with anything electrical, it’s always best to be as safe as possible.
