"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."

"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."

"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

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. 

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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.
