Under $5,000 is the entry level for a standby generator, usually a smaller air-cooled unit of about 10 to 14 kW, sometimes with a transfer switch in the box. It will run the essentials in an outage, such as the furnace, refrigerator, lights, well pump and perhaps one air conditioner with load management.
The price is only the unit, so add the transfer switch if it is not included, plus the pad, gas line, electrical work and permits. Check the fuel type available at your home, the load you need to back up, and the warranty and service options in your area, since an unserviceable generator is a liability.
