"I hired Brite Electric to expand the electric capacity at my house and to add a 240 volt outlet for my ev car charger. Pete did an excellent job performing these tasks in a timely manner. He effectively communicated in detail the job tasks and answered all my questions. Pete was dependable and did not vary above the quoted price. I would definitely call Brite Electric for any future electrical work."

"I highly recommend Thundercolt Electric. Gerardo came out, provided a bid and when I advised I was ready to get started they quickly got started on the project which included recessed lighting, new electrical outlets and switches, changing out electrical outlets and light switches, installing a surge protector for the home, installation of ceiling fans and a ring doorbell. Thunderbolt did an excellent job and I would hire them again for any work I may have and Iâ d recommend them to family and friends."

"I needed an electrician for an issue in one of my bedrooms in the house that my skill level could not figure out. I had one light switch and power outlet that was not working. I could not figure out where the issue was located. I decided to give Allgood Electric a try with the issue. It was very easy and user friendly to schedule an appointment from Allgood Electric homepage. They even give you a few choices with quotes to select from for your appoint. The scheduling wizard was great because not only do you get an estimate, but it also allows you to pick the date and time slot you are looking for ALL online. This feature alone for Allgood Electric is top notch. David was the assigned technician and came first thing in the morning at the beginning of my estimated time slot. I received two calls before David showed up. I received one in the morning from an office clerk and one from David to let me know he was 30 minutes from the house. Those calls ahead really help to get you ready for their visit. David was very professional and friendly. He was quickly able to diagnose the issue. Once he diagnosed the issue he was able to get my electrical issue fixed on both my outlet and light switch. No one wishes for electrical issues in their home, but if I have another problem I am happily going to give Allgood Electric another call."

"Outstanding communication and very professional service. I would highly recommend Mr. Electric. Received both e-mails and texts on appointment to include a photo and short bio of the actual electrician (Brad Mason) who would be doing the work. Wish all home service providers did the same. Brad was on time (actually a few minutes early). He installed 30AMP breaker and associated RV plug in our garage. To avoid any sheetrock repairs it was necessary for him to drop the line to the house electric panel through a wall with foam insulation, with very limited head/body clearance for him to work. No mess left behind from the actual plug installation on another wall."

"I recently had a light fixture installed in my office and an electrical outlet relocated to a different area, and I couldn’t be happier with the results. The electrician was professional, punctual, and paid close attention to every detail. The installation was clean, the work was completed efficiently, and everything looks and functions perfectly. It’s clear they take pride in their craftsmanship and customer service. I highly recommend them to anyone looking for quality electrical work. Thank you for doing such an amazing job!"

Electrical FAQs, answered by experts

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

A low-voltage landscape lighting system using 15 to 20 LED lights for six hours a night will average about $5 to $10 a month in electricity costs. This is considered affordable lighting for many homeowners. Most modern landscape lights use LED bulbs, but some older styles may use halogen or incandescent bulbs, which can cost up to five times more than LEDs in electrical costs.

Single switch installs are quick DIY projects, but you should consider enlisting the help of a pro for more complicated replacements—like a smart switch or if you live in an older home with outdated wiring. Professional electricians are trained in the latest code regulations. They are also insured, licensed, and bonded.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
