Can't recommend them high enough!"

"Had an electrician out to give me an estimate on replacing my electrical panel. Decided against replacing it because that wouldn't have solved my issue. My house was built in the 60's so it needs all new wiring. I just had him show me which outlets were on each of the channels so that I could spread out my devices that needed a lot of power, specifically my space heaters."

"Wallace provided outstanding electrical service from start to finish. He arrived punctually and maintained a professional demeanor throughout the project. His technical expertise was evident as he successfully installed three light fixtures, replaced one outlet, and expertly repaired another outlet. What truly set Wallace apart was his attention to detail and respect for our property. He cleaned up thoroughly as he worked, leaving no mess behind. Additionally, he was very considerate of our schedule, working efficiently without disrupting our day. I highly recommend Wallace for any electrical needs. His combination of technical skill, professionalism, and customer service makes him a standout contractor"

Electrical questions, answered by experts

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

Yes, a water leak poses a major fire risk at your home because water is a conductor of electricity. Water that comes into contact with sparks or electrical wires can instantly ignite flammable materials. Additionally, any type of exposure to water can cause wires and other electrical components within your home to corrode. When assessing categories of water damage, it's important to know that even a small amount of moisture near wiring could cause sparks that lead to a fire.

Volts and watts aren’t directly convertible units—they measure different aspects of electricity. Volts measure electrical potential, while watts quantify the power. The relationship between the two is defined by the equation: Power (watts)= Voltage (volts) x Current (amperes). In other words, the product of volts and amps results in watts, but there is no fixed conversion of volts into watts.

There are a few signs of a faulty or failing dimmer switch. This includes your dimmer overheating or feeling warm to the touch, buzzing or clicking noises coming from the dimmer, your dimmer failing to properly dim the lights, and flickering lights. That said, these signs could signal other electrical issues. You’ll need a pro to figure out if your dimmer is the source.

Most mechanical and digital timers will only turn your Christmas lights on and off once per day, but a smart timer will likely do so as many times as you want.
