"It was this Christmas eve during a storm and we lost power. I started up my emergency generator and it was working just fine. As the night wore on the generator started to loose power and after about an hour finally stopped generating power. I have two sump pumps that keep my basement from flooding as water levels rise from beneath and 3 refrigerators and a freezer full of food. I was aware that the upcoming New Years eve should be stormy as well, therefore getting the generator up and running was a priority. I called numerous companies that claim to service and repair generators although until I reached Rick at Raw Power none actually did repairs. Rick came to the rescue and my priority became his priority. He scheduled the repair the very next day. On the scheduled day he called to let me know he would be at my house an hour early. He is a total professional that goes the extra mile we so frequently hear about but seldom see. Once at the house he quickly analyzed the problem. Since he didn't have the required part, he found a store that had it, left to get it and promptly returned to complete the repair. There were no surprises as he was completely up front as to the costs. He even spent extra time with me reviewing how to run and maintain my generator, as well as, proper electrical connections."

"These guys are great - had a couple of issues and they immediately helped without question; including come to change a manufacturer's defect long after the job was completed at no additional charge. I will be hiring them for any future electrical projects and recommend you do the same!"

"Revolution Electric updated and reworked all our electric for our 100 year old home remodel. We still had knob and tubes under our plaster walls. They modernized all of our electric from timed lighting indoors and out, full WiFi and boosters, generator installation and even buried our electric lines outside. They are professional, timely, courteous and so easy to work with. They stayed on budget, patiently helped me find cost effective solutions and fully trained me on how to manage all of the systems we installed. I fully would recommend them and rate them a 10 out of 10."

Generator Install questions, answered by experts

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.

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.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
