Generator Cost ComparisonsUnderstanding Generators For The House and How Much They Cost: An electric generator is any portable device or mid-sized appliance that uses a fuel source such as natural gas or gasoline to produce electricity; a home generator is an electric generator built to generate enough electrical output to provide for typical use in a single-family residence, usually designed for use as an auxiliary power source during an electrical service interruption. Roughly the size of a typical residential HVAC or central air conditioning unit, home generators are most often installed outside the home and can be hooked up to natural gas lines or standalone tanks of liquid propane. Some home generators have their own fuel tanks, as well.


What to Look For In a Generator For Home Use: Look at your power bill or call your electricity provider to estimate your standard watt usage, and buy a generator that provides the output you’ll need. Fuel type and source options are also essential considerations, especially if you don’t have natural gas service to your home. An automatic transfer switch is standard on most home generators and is a must-have feature if you want your generator to come on by itself when you lose power to your home.

Common Types: Standby (most common) and Portable. Also, trailer mounted or towable.

Generator Power in Kilowatts (KW): Typically ranges from 15 -100 KW

Fuel Type: Gasoline, Diesel, Propane, or Natural Gas.
