"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."

"SeaTown installed a standby generator. They provided us with a wide range of options, and were very good about advising us of the ramifications and external costs associated with each. They coordinated permits, locates and utility requirements, making the process easy for us. The installers were courteous, respectful of our property, and did a fine job. We are now using them to install AC."

"Three electricians worked on the job & completed it in 3 1/2 hours! I was expecting it to be done in 5-6 hours. They even hooked their generator up to my big freezer! The City inspector just checked their work, said it was a job well done! I would definitely hire them 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."

"From start to finish, this crew did an outstanding job of making sure my generator panel and switch were placed logically and cleanly. I really appreciate the time they took, especially Miguel who walked me through each step. Highly recommend."

"Electrician Alex was a complete professional in every way. We upgraded some electrical outlets in crawlspace, outside outlets, which included a generator hookup that works perfectly. His work speaks for itself and we were completely satisfied. Alex is so personal and we were so comfortable having him in our home. What a great guy! We will exclusively call Alex from here on out for any electrical needs. RENEW ELECTRICgets our highest recommendation."

Generator Install questions, answered by experts

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.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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.

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.
