"John called me to discuss my problem with my generator. After a few questions, John suggested a few quick easy things I could do to correct the problem. After completing the repairs he suggested, the generator operated perfectly. I asked him what I owed and he said no charge and he was just glad I was able to get it running. It's rare to find someone like John in today's business world. Believe me, any chance I get I will refer Farr Service for anyone looking for small engine repairs."

"Unstoppable Electric LLC just installed our Tesla Wall Connector, and wow—what an incredible experience. They were super responsive from the first message, easy to schedule, and showed up right on time. Max is very knowledgeable, professional, and genuinely nice to talk to. He took his time to do everything perfectly—clean, precise, top-quality work with no rush whatsoever. Explained everything clearly, made smart suggestions, and left the garage looking flawless. Pricing was fair and transparent—no surprises. Definitely now my go-to electrician in the area! 10/10 recommend! Thanks again for the stellar work! ⚡️🚗"

Generator Install questions, answered by experts

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.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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