Generator Install FAQs, answered by experts

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.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more.
