"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!"

"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."

"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

Yes. You should always turn off the power to the work area before beginning, use a voltage tester to ensure it’s off, and wear protective gear, such as insulated gloves or safety glasses, to prevent risk of injury. Proper wiring and grounding techniques are also necessary to make sure the job is done right the first time and won’t harm any future homeowners. 

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.

The cost to install or replace a circuit breaker depends on the price of the unit itself and the complexity of the installation. A new circuit breaker typically costs between $10 and $100, with standard breakers being the most affordable and GFCI or AFCI types costing more. If you are upgrading to a higher amperage, a 200-amp circuit breaker can cost between $250 and $350. The average total cost for professional installation is around $700, but this price varies. A simple replacement into existing wiring will cost less than a more complex project that requires opening walls, running new wires, and securing permits.

Yes, professional installations typically include wiring, switches, and circuit adjustments for safe operation.

While the National Electrical Code (NEC) does not set a strict limit, a common guideline is to have a maximum of eight outlets or receptacles on a 15-amp circuit. This rule of thumb, which equates to about one outlet per 1.5 amps, helps keep the total electrical load safely below 80% of the circuit breaker's capacity. It is important to consider the power demands of any devices or appliances that will be plugged in, as overloading a circuit can lead to tripped breakers or create a fire hazard. To ensure the safety and code compliance of your electrical system, consult with a licensed electrician.
