"JK Flores LLC sent Jorge and an associate to install a Big Ass fan and to service another Big Ass fan that had been giving us trouble for over a year (others had tried to fix it before). Jorge was on time and sensitive and attentive to our thoughts and concerns. He was quick at his work but was clean and never gave us any concern that he would sacrifice speed over quality of his work. We are already looking for other electrical issues in our house for Jorge to attend. We would highly recommend him to anyone needing electrical help."

"I would highly recommend Naymar Electric to anyone looking for an excellent electrician. Their prices were very fair and competitive, their estimated timeframes given were more than reasonable and turned out to be accurate. I appreciated that David was readily available to answer my basic questions, as well as use his experience and creativity to wire the house in a way that would provide for future inhabitants and household configurations. He was very knowledgeable and informative, as well as creative and aesthetic, and he and his crew were hard workers that paid attention to detail and left the house easy to patch when they were through. I am so glad I went with Naymar Electric, they are now my go-to!!"

Electrical FAQs, answered by experts

A pigtail is the only safe way to connect an electrical device to more than one circuit wire. Connecting multiple wires to a single screw terminal is extremely dangerous and must never be done. Many electricians will opt for pigtails even when there are multiple screw terminals available so that the device in question won’t halt the flow of downstream current when a problem arises. 

Typically, refrigerators should not be plugged into GFCI outlets. This is another appliance with a motor that can be prone to a little current leakage. Using a standard outlet saves nuisance tripping and the potential of waking up to a refrigerator full of warm food. The only exception is when the refrigerator is in a garage, where all outlets must be GFCI.

A wire stripping tool is the easiest way to strip sheathing or plastic insulation from electrical wires. A self-adjusting wire stripper cuts and removes the sheathing without damaging the core wire.

A full home inspection can cost nearly $350 on average, but inspecting the breaker box specifically is likely to be lower, between $100 and $200. Don’t confuse this service with a basic breaker trip check, which doesn’t take long and is usually billed at $40 to $50 per hour.

If the electrician discovers a serious problem and needs to replace a breaker, it can cost between $100 and $200 in additional expenses. Although rare, replacing the electrical panel typically costs between $500 and $2,000.

Baking soda is an effective fire reduction method. However, flour and baking powder are very dangerous around flames. Flour is flammable and it can also conduct electricity. The combination can cause serious injury from electrical shock and worsen the situation by adding fuel to the fire. Baking powder is also not an option as it's also highly flammable.
