Mini Split BTU Output Calculator
BTU Output = ((CFM × 60) ÷ 13) × (Return Enthalpy − Supply Enthalpy)
Testing Setup
Place the indoor unit in Cooling Mode, lower the temperature setpoint to the minimum setting, and set the indoor fan to the highest speed available. Allow the system to stabilize before recording airflow and enthalpy measurements.

ℹ Airflow Rate (CFM)
Use the airflow rate from the indoor unit's submittal or service manual. If multiple airflow values are listed, use the highest CFM rating (maximum fan speed).
