Standby generators range in size—the more kilowatts they have, the more they can power—and are designed to be installed as a permanent part of the home. Automatic standby generators are costly—ranging in price from $7,000 to $14,000 depending on where they’re being installed, the size of the generator, and other factors. In Miami, for example, permitting can cost close to $2,000 alone, whereas in other areas of the country, a permit could run less than $100.
Standby generators offer a homeowner peace of mind, said Andy Badertscher of J.B. Electric in Auburn, Calif.
“We have had customers with pets or with fish tanks that need to make sure their animals are safe and healthy regardless of power outages, so they have chosen the standby units with automatic start up,” Badertscher says. “Even if you are thousands of miles away, you know your home will have power in the worst of conditions. Refrigerators, freezers, basement sump pumps, wells and HVAC (equipment) will still be running. No frozen pipes, no flooded basements and no spoiled food.”
Portable generators cost significantly less—you can purchase one for less than $1,000 and they don’t require permits and inspections. However, they are designed to run for only a short period of time, they provide less power to the home and have to be manually started.
“Most portable generators currently on the market have push-button starts, but still require someone to be home, start it up and plug it into the generator receptacle,” Badertscher says. “This is a good option for renters or for someone who wants to be able to take the generator with them if they move.”
It’s important that homeowners who invest in a standby generator hire a contractor who is properly licensed and is certified by the product manufacturer. Having an unqualified contractor install a generator could be a costly mistake if he or she doesn’t follow the proper building codes.
“Look for contractors who are factory certified for the manufacturer you are purchasing from,” Badertscher says. “Not only will they have greater product knowledge to assist you with the size and type of generator to purchase, but they will also be able to warranty the unit for you if a problem comes up during or after installation.”
