"Frank responded quickly to my inquiry and provided an estimate. We agreed the work would be done within a month. Frank arrived on the agreed upon installation date on time, worked efficiently, kept me apprised of his progress. He arranged for all required inspections and coordinated work with Duke Energy employees. I would definitely hire Frank for any electrical work and recommend him highly."

"Everything went really smooth. Larry & Aaron really know what they’re doing. We needed to add a GFCI receptacle and they had to cut into the exterior of our home. They also added a circuit switch for a generator hookup. This was no simple electrical work and it took some expert skill. These guys KNOW what they’re doing and will be my go to electricians in the future. HIGHLY recommend!"

"Review: I recently had an EV charger installed at my home, and I couldn’t be more pleased with the service. Shield electric was professional, knowledgeable, and efficient throughout the entire process. The installation was completed flawlessly, and everything was left clean and organized. Our electrician took the time to explain the setup and ensured everything was working perfectly before leaving. I highly recommend him for anyone in need of electrical work, especially EV charger installations!"

Generator Install FAQs, answered by experts

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
