"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 is a well-oiled machine! From the start (estimate of costs) to the final installation and safety checks I knew I picked the right company to do my generator project. All employees that were involved were knowledgeable and answered all my questions thoroughly and in a way that made sense to me. I plan to use this company again."

"G&S Heating is the best of the best! They just replaced our 1995 Lennox furnace that they installed with a 2020 Lennox furnace. The crew was phenomenal in craftsmanship and attitude. Our furnace is in the tight crawl space under our home which is a pain in the @#*! They really worked well together and it was so cool to learn that one of the guy's father had installed our furnace back in 1995 and he is still with G&S! Their entire operation focuses on customer service and satisfaction from the phone contacts to the sales reps to the job planners and finally the installers! I am giving G&S my highest recommendation and will have them install our new Kohler 20KW whole house generator soon. Thank you G&S... Tom H"

Generator Install questions, answered by experts

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

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.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.
