You never know when the power might go out, especially during severe weather.
's Angie's List report, what you need to know about home generators.
When it comes to generators, homeowners have a couple of options.
Portable generators are cheaper than permanent units, but are designed to run for shorter time periods and are powered by gasoline, so they'll need frequent refueling.
Permanent units can start automatically or with the flip of a switch - and can power everything in your house.
"When deciding what type of generator you might want to have its dependent on your potential usage. If you are living in the city and you may just need it for a few hours a portable generator can be a great option, they cost about $1,000. But if you live in a rural area where you may be without electricity for a longer period of time or if you have medical issues that require equipment to be plugged in you are probably going to go with a whole house generator," Angie Hicks with Angie's List said.
Generators do require some maintenance. You should regularly check your generator to make sure it starts and is operating correctly.
And always follow specific safety instructions when using generators. Put the generator outside on a level surface in a well-ventilated area at least ten feet away from the house to avoid carbon monoxide poisoning.
