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.)* |
| 9K BTU | Up to 375 Sq. ft |
| 12K BTU | Up to 500 Sq. ft |
| 18K BTU | Up to 750 Sq. ft |
| 24k BTU | Up to 1000 Sq. ft |
| 36k BTU | Up to 1500 Sq. ft |
*Ceiling height, insulation, and local climate may impact the coverage area. For example, an uninsulated room will require more power than a well insulated room.
