"Tom and his team did an amazing job. They showed up on time, were very professional and cleaned up after each day. Their work was neat and they also installed quality hardware - which not may electricians do. I would highly recommend TFC Electric for anyone looking for a great job at a fair price. Will definitely use in the future."

"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."

"Mohammad was super helpful in diagnosing and solving our electrical issues. He went above and beyond to help label the electrical box which was mislabeled by the previous owners. Would recommend."

"Came to my house the same day and completed the job. Mike the electrician was a nice guy and did a good job. $200 the first hour and $100 each additional hour. Changed existing ceiling fan, switches and outlets. I already had the parts, took 3+ hours, cost almost $500 with tax. Not sure if this is standard. I called them after another electrician who was supposed to come that day canceled."

Electrical questions, answered by experts

Just as fluorescent lights are more efficient than incandescent lights, LED lights are more efficient to run than fluorescent lights. The specifics will vary from product to product, but LED lights are typically twice as efficient as equivalent fluorescent lights. A 13-watt CFL bulb can replace a 60-watt incandescent bulb, but a 6- to 8-watt LED bulb can offer the same amount of brightness. Fluorescent lights offer about 50 lumens per watt, while LEDs offer about 100 lumens per watt. LED light bulbs typically last two to three times as long as CFL bulbs, too. 

No, both switches do not need to be on for a 3-way switch to work. When the two switches are in opposite positions, the circuit is open and the light is off. Flipping either switch closes the circuit and turns the light on. So, either switch can turn the light off independently, and both switches do not need to be in the same position for the switch to function.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

To prevent a plug from overheating, always ensure that the electrical load connected to the plug does not exceed the plug's capacity. If the plug feels hot to the touch or emits a burning smell, immediately shut off the circuit breaker and unplug all devices from the hot outlet. Prevent electrical fires by avoiding using extension cords or adapters with the plug, as they can cause it to overheat due to increased resistance. Additionally, ensure that the plug is properly inserted into the outlet and that the outlet is not damaged or loose. 

Yes, but our analogy with the water hose doesn’t really work here. You see, electrical flow isn’t constant: It ebbs and flows like waves, coming in pulses of power. Hertz measures the rate of change in the flow of electricity, or how often it ebbs and flows. For example, 60Hz means that the electrons pulse through wiring 60 times per second. When they are pulsing, they’re in a brief retreat. Almost all United States equipment is rated for 60Hz.
