"They did a great job and fixed my mast on my house. The only thing I am questioning is the time they spent doing the job. I was unable to get into Angi for the time they were coming, so I had not called NorthWestern Energy to get the power shut off. I was charged for 3 1/2 hours."

Generator Install questions, answered by experts

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.
