"I was pleased with the work done by Allred Electrical. The process of removing my old fuse box, installing a new panel, having the town inspector come out, and the electric company coming out to remove the old outside box took longer than expected. Allred was short handed because an employee was out due to illness but they have no control over the town inspector's nor Duke Energy's schedules. Even though the process from start to finish took a little longer than expected I was only without power for part of one day by they came back on a Sunday to check on something I thought was a problem. The only problems I can think of were the fact that I couldn't get a detailed invoice prior to the job of what was to be done with a cost break down and I'm waiting for them to come back to add outlets. So I will update this review once the full job is complete."

"Great to work with from the initial quote to the final part of the installation of our generator. Arrived on time and finished ahead of time. They provided good insight into the workings of a generator and good ideas as to placement, size, etc. This was simply a great experience and I would highly recommend Southern Accents for any electrical needs."

Customers say: True professional

"Great experience with Dr. Sparky Electrical Service. Angel was our electrician, and he was knowledgeable, professional, and thorough. He took the time to diagnose the issue and clearly explain what was causing the problem and what needed to be done to fix it. The service was reasonably priced, and I appreciated the communication throughout the process. I would definitely recommend Dr. Sparky and Angel for anyone needing electrical work."

Generator Install FAQs, answered by experts

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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

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.
