"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!"

"He received the notice early on Saturday morning and called within an hour. He was at my house to get the estimate done an hour after that. We agreed to have the install done the following Friday to give him time to get the permits done. He and his son we exactly on time and the price was actually lower than I anticipated. A totally professional job. This guy is on my list for my next electrical job."

Generator Install questions, answered by experts

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
