Airflow Test (RCA)

Take Out The Guesswork With A Refrigerant Charge Airflow Test.

The refrigerant charge is vital in how the system consumes energy and conditions the building. An improperly charged system can cause various problems such as cooling issues, energy spikes, and equipment failure. When testing the system, the HERS Rater compares the data to equipment specs to verify the charge is within the manufacturer’s specifications. Airflow refers to the actual flow of cold air created by the air conditioning system. Refrigerant Charge Airflow must always be done in conjunction with the Cooling Coil Airflow but is only required in climate zones 2, and 8-15 with a replacement of a refrigerant containing component.

Additional Information About Refrigerant Charge Airflow Tests

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

This test is required by California in specific scenarios involving different climate zones and installed equipment. If you have questions on if a RCA charge is required for your specific setup, give us a call today.

The main benefit of an RCA test is it will determine if your system is properly charged for cooling. If it’s not properly charged, the unit can increase energy bills, freeze coils and lead to the system blowing out warm air.

During a Refrigerant Charge Airflow Test we use a Fieldpiece Digital Manifold.
