"Mr. Electric responded promptly, showed up at my convenience and thoroughly inspected my needs before giving me an extremely reasonable quote. My service person was Elijah, who was so very competent, professional and courteous. I felt totally comfortable having him in my home. He installed two electrical outlets outside my home and converted a motion sensor floodlight to a dusk to dawn one. He explained everything he was doing and made sure that I understood. I couldn't have asked for better service!"

"We've used Scott for several projects over the years, and he's been fantastic every time. He was willing to take on some smaller jobs that many electricians wouldn't bother with, including replacing a floodlight that had been broken for years, installing a new Ring floodlight camera, and fixing an under-cabinet kitchen light. He responded quickly, showed up when he said he would, and got everything working perfectly. He also helped us with a much more complicated project when our new wine refrigerator wouldn't fit because an electrical box had been installed too far forward. It was right before Thanksgiving, and we were worried we'd be stuck without a solution. He was able to reroute wiring through the basement, relocate the box, and get everything finished quickly so we could install the fridge in time for the holiday. He's knowledgeable, reliable, reasonably priced, and does excellent work. It's hard to find contractors who communicate well, respond promptly, and genuinely care ab"

"I called APS about getting a standby generator for my home, and the whole experience was great from the start. They took the time to explain everything in a way that actually made sense and walked me through what to expect instead of just trying to sell me something. What really stood out to me was how thorough they were. They noticed my gas meter was undersized for what I already had and helped get that addressed with the utility company before it became a bigger issue. That?s the kind of thing most people probably wouldn?t even know to ask about. Their pricing was competitive, communication was easy, and everyone I dealt with was professional and knowledgeable. The 10-year warranty being included was a nice bonus too. Overall, I felt like they genuinely cared about doing the job right. I?d absolutely use APS again and would recommend them to anyone looking for electrical work or a home generator."

Generator Install FAQs, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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.

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.
