"Klaus moved our wired electric panel and re-wired the entire kitchen. He added amazing lighting including recessed lighting, under counter lighting and toe kick lighting. He installed relocated electrical receptacles for the dishwasher, garbage disposal and water pump. Did beautiful finish work. Very good at communicating and saying yes when I asked for more. Pricing very reasonable. Very dependable and amicable. Highly recommended."

"On August 2025 I had two Hunter ceiling fans installed by Mike and was very pleased with the results. The installations were done efficiently and professionally, with both fans mounted in the second-floor loft and bedroom with 8’ ceilings. Communication was clear throughout the process, and he made sure everything was working perfectly, including the wall controls for each fan. I highly recommend their services for anyone needing reliable and quality electrical work."

"Used this company previously and again it was a pleasure from beginning to end. I would give him 10 Stars if I could. Referred William to a close friend of mine and she was just as pleased. We both sleep better during our bad Florida thunderstorms. A friend of mine lost their home due to lightning. They got out just in time couldn’t save anything but their lives barely. I urge all to install lightning rods."

Customers say: True professional

"Very professional and efficient. Arrived timely, very knowledgeable, and efficiently repaired appliance. Our General Electric large refrigerator was not properly cooling. Found door leakage, ordered the part, and returned to replace the seal. No markup on the part, no added time to repair - entire transaction was very fair. Could not ask for a better experience."

Electrical questions, answered by experts

In most cases, line wires are located at the bottom of a panel or device, while load wires are located at the top. Line wires are generally black, while load wires are typically red or black. To tell for sure, you can use a multimeter or volt pen to test the wire. A live or line wire will always carry a charge, while a load wire will only carry a charge when it’s in use.

If you need to run a wire from the meter to the breaker box, start by turning off the power using the main switch to avoid injury risks from live wires. Then, locate the ground wire from your meter and connect it to the ground bar of the breaker box. Connect the neutral wire using the same method to improve your circuit efficiency.

Next, locate the hot wires running from the main switch to the meter. To connect them to the correct terminals from meter to breaker, unscrew the nuts of the breaker hotwire terminals, insert the positive hotwire, and ensure it’s firmly attached. Finally, secure the wires with electrical tape and wire tie cables before re-securing your breaker box. Keep in mind that this process can be dangerous, so don’t hesitate to hire a local electrician.

The cost to upgrade an electrical panel ranges from $1,200 to $2,000, depending on the type of electrical panel you need and the size of your home. Amperage plays a central role in determining the cost, so calculate your home’s electrical load before purchasing. For example, a 100-amp and 400-amp panel vary widely in cost. 

You can have power but no lights if the light switch is damaged. A damaged light switch is often caused by regular wear and tear or loose wires. In addition, simple problems such as a burnt-out light bulb or an unplugged lamp could be the cause of not having working lights.

Different types of light switches include single-pole switches (the standard switch in your home), double-pole switches, toggle switches, three-way switches, four-way switches, dimmer switches, and more. 

A single-pole light switch controls the power to a single device, whereas two-way, three-way, and four-way light switches control lights from different locations, increasing the number of connections in the home.
