"Nikolai and Kevin with Gavin have all worked on our home in the Hemingway area of Georgetown County. We have had the panels inside/outside replaced, an outlet replaced, range and microwave rewired, a home and AC surge protector installed, re-routing of outlets to separate circuits that were constantly being overloaded, they are coming out again this coming Thursday of June 2026 and we still have more in the future as we save our funds in preparation. All the electricians have been professional, polite and thorough. I had some detailed questions at one point since we are having so much done to our house and new garage and they have answered them without fail. I would not have anyone else do the work. Thank you to Nikolai, Kevin and Gavin (team), Bobbie and Robert."

"The technician's (Tim and Chaun) that did the installing of my HVAC were courteous and professional. Tim made sure everything was working to his satisfaction before he left and told us he would check back in a day or so to make sure it was functioning properly. My wife and myself very pleased. I should also state two years ago we had a new HVAC installed by Swift and continually had problems with it. After many service calls with little luck correcting the issue, Swift installed a new unit. Five more stars to Swift for integrity!"

"Alex not only installed my 45 kw whole house generator with an automatic switch, he also upgraded our house service and installed a new 200 amp meter pan breaker panel. Itâ s so nice having the panel wired properly. No more breakers tripping!! He was on time, polite, respectful, and left the house cleaner than it was when he arrived."

Generator Install questions, answered by experts

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
