Mini Split FAQ

 

What BTU rating should I choose for my air handler?

  • This depends on the coverage area/room size you are trying to heat/cool
  • An Air Handler's BTU is how powerful the fan is. A higher BTU rating will be able to heat/cool a larger area
Air Handler BTU Coverage Area/Room Size (Sq. Ft.)*
6K
Up to 200 Sq. Ft.
9K
Up to 375 Sq. Ft.
12K Up to 500 Sq. Ft.
