"Based on Angi, Yelp and Google reviews, we chose a couple of well-reviewed, Generac-certified companies to come out for estimates for installing a whole-house generator. Given the amount of house/property that we wanted to power (our house, septic, well, mother-in-law dwelling, etc.), both recommended the 26kW and both were about the same price for installation. But we liked Joseph's knowledge, honesty and responsiveness to our email/text questions afterward, so we went with Smart Electric. Lead electrician Keith and crew were prompt, friendly and professional throughout the installation on the day we had scheduled. A wiring issue required Keith to return for several Saturday visits, and we appreciated his communication and determination to make sure we were completely satisfied. We would definitely call Smart Eclectic again."

"Our home had inadequate electric service. McCarthy Electric provided a bid to install 200 amp service to support our growing needs. My interactions with their team has been the most satisfying experience I have had with a service provider. The service was upgraded per the bid with no drama, in a timely fashion. I was kept informed of important developments in a courteous and professional manner. I will be a return customer for any future electrical needs."

"We had In-House Electrical replace/upgrade our main panel as well as setup a generator hook-up and A/C outlet outside. Adam and Avery were phenomenal - they were thorough, kept in constant communication with me during the project to ensure things were being done as I liked, and left the place looking better than when they showed up. They'll be my first call in the future for any electrical work I need done."

Generator Install questions, answered by experts

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.

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.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.
