Test and treat acid in refrigerant or risk reduced equipment lifespan
The acids sometimes found in refrigerants can be formed by chemical reactions with components and/or materials of construction, lubricating oils, and/or impurities.
The instability of the refrigerant, and thus the formation of acids, is accelerated by elevated temperatures which could be the result of improper operation, such as a failed condenser fan or clogged airflow path.
