"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

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

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.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
