"This was the first time I used Home Advisor to find a contractor. Home Advisor linked me with Mr. Electric who did an outstanding job. They were on time, on budget, courteous, professional, and totally a pleasure to work with. Thomas installed a 50 and 30 amp service for us at our property servicing two RV lots as well as installed a power pole with a meter box for the power company to tie into. Jan was a pleasure to work with as she was the voice for the company dealing from everything from scheduling to invoice as well as general questions. Jan was very pleaseant and professional. We will use Mr. Electric in the future and highly recommend their service..."

"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."

"Overall it went well. He had to reschedule twice, and both times I was not notified he was not going to make it. I had to call multiple times to find out. Once he did show up, he installed the box in the ceiling which turned out to be a harder job than was anticipated. The box works and my ceiling fan is working great."

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

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.

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.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.
