"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."

"From estimate, to selection of The Juice Company, to scheduling, they made the entire process painless. Had 2 15 amp "peanut" breakers installed to replace an existing breaker and establish a new circuit, and 2 new outlets installed. We also had low voltage network cable roughed in so I could terminate it later, and everything was done not only properly, but quickly. I would definitely recommend them to anyone needing electrical work done in the South Sound region."

"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."

"Nick went above and beyond to install my home car charger. He had to get through concrete in my crawlspace and installed the charger on the wall which I did not expect him to complete. The price was reasonable when compared to two other estimates. I would highly recommend First Choice."

"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."

Customers say: True professional

"B-Moore was the only contractor out of the Home Advisor list who answered the phone and returned my voice mail questions. Installed switch panel for the back-up generator and two outdoor light. Demonstrated the hook-up process and walked through the house to make sure the system worked. Price was fair, I checked with a friend who is a contractor, and the military discount is appreciated. They will be the ones I choose for the next electrical work. Polite, articulate, and skilled crew."

Generator Install questions, answered by experts

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency.
