Low Airflow per Ton – Efficiency Cut in Half

Every HVAC system is designed for a target airflow, usually around 400 CFM per ton. When airflow drops below that, efficiency and comfort disappear.
Chatterbox measures actual CFM based on power, pressure, and temperature data. A drop below spec means the blower, ducts, or filter are restricting flow.
Once corrected, you get full capacity, lower bills, and quieter operation.
