Cooling Coil Airflow (CCA)

Ensure Your System has the proper air flow to maximize performance

The primary purpose of testing the airflow across an evaporator coil is to verify the cooling system has an adequate flow to maintain system design. This is important because system performance can be affected by too much or too little airflow. Low airflow can reduce the equipment’s life, cause the system’s coil to freeze, or damage the compressor. High airflow will lead to high energy use, low subcooling, and may cause discomfort because the supply air is not properly conditioned.

Additional Information About Cooling Coil Airflow Tests

Any homeowner who has recently done a mechanical changeout in their home needs a cooling coil airflow test. 

This test is required anytime a mechanical changeout has been performed. This requirement applies to all climate zones in California.

The purpose of this test is to measure the airflow across the cooling coil in your HVAC system. If the cooling coil is not operating in a safe temperature range, the system can freeze over or  Prevents the system from freezing and

For a CCA test we use a Balometer Capture Hood made by TSI Alnor. This air balancing tool is electronic and highly efficient in reading air volume.
