Generac Air-Cooled Generators & Guardian Series Installation in Florida, Tennessee, Kentucky and Mississippi
The Guardian Series is the #1 selling line of home backup generators: permanently installed, automatic, and running on your home’s natural gas or propane.
Air-Cooled
Why Choose Air-Cooled Backup Power?
Air-cooled generators are Generac's home standby line, from 10kW units that keep the essential circuits running to 28kW units that can back up a whole house. Larger homes and commercial buildings that need more move up to liquid-cooled models.
Essential Circuits or Whole Home
Smaller units power the necessities, like lights, the refrigerator and an AC unit. Larger units, or a mid-size unit paired with a load management switch, cover the whole house.
A Compact Footprint
Guardian units from 10kW to 26kW share one enclosure, 48 by 25 by 29 inches, on a concrete pad beside your home.
Quiet, Automatic, No Refueling
The weekly self-test runs in a low-speed Quiet-Test mode at about 55 to 57 dB(A), and the generator runs on natural gas or propane, so there is nothing to refuel.
