"Lightning damaged several of the electronics in our house. I scheduled for an electrician to come out today and Dave was here, on time. He is professional and friendly...and he like dogs! Dave quickly and efficiently diagnosed each problem and was able to repair some items and give us direction for non-electrical repairs, such as HVAC and plumbing. Next time we need an electrical service, I guarantee it will be Gunther’s Electric!"

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."

"Mark from Duke's Electrical Services was recommended by a friend in the home improvement business whose referrals have always been A+, and Mark certainly lived up to that reputation. Mark and his son were professional, punctual, and communicative. They texted before arriving and showed up exactly on time. Mark performed a thorough electrical inspection, took photos, and reviewed everything with me so I understood the condition of our system. I also asked about a few smaller projects, including a dock light switch and a deck remote-control switch that weren't working. Mark followed through on his promise to return, contacted me within a week, and scheduled the repairs. During that visit, I added two more switch replacements, and they completed all three jobs in under an hour. What impressed me most was their attention to detail. After finishing, they vacuumed the work area. As someone who appreciates cleanliness, that meant a lot. Professional, efficient, cleanliness, very rare find."

"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."

"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

The number of outlets and lights you can safely run on a single circuit depends on the circuit's amperage and local electrical codes. A general rule is to allow one outlet or light fixture per 1.5 amps, keeping the total load under 80% of the circuit breaker's capacity. For example, a 15-amp circuit can typically support up to eight outlets or lights, while a 20-amp circuit can accommodate up to ten. Always consider the combined power usage of all connected devices and fixtures to prevent overloading. For specific guidelines and to ensure safety, it is best to consult local electrical codes or a licensed electrician.

If only half of your outlet works, there are usually two possible causes: faulty wiring or a half-hot outlet. The first thing you'll want to do is check the circuit breaker panel to ensure that it's not tripped. If your circuit breaker isn't tripped, turn off the electricity and inspect the wiring to see if anything has come loose or corroded. 

If you have a half-hot outlet, it means half of the outlet is controlled by a switch somewhere on the same circuit, which should be nearby. This is an intentional electrical design commonly found in rooms without overhead lights.

The color code for the common sprinkler wire is white, and then you can assign the remaining color codes to the rest of the wires for different sprinkler zones. For example, you could use red for the first zone, then blue for the second, and so on.

Color-coding helps you keep track of which wires go to specific zones so that you or a pro can address any issues or repairs quickly. Check your local electrical code for any requirements regarding sprinkler wire colors.

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.

You should always turn off a breaker whenever electrical work is being done. This step can prevent electrical shock and injury. Also, if a breaker is repeatedly tripping, it can mean there is an electrical overload, and it should be shut off. You should contact an electrician to figure out the cause. Make sure to review how to turn off your circuit breaker safely if you do it yourself, and follow safety precautions to avoid severe injuries.
