ABSTRACT:
A method for cleaning a heat exchanging coil in an air conditioning unit using a low-pressure cleaning system to remove foreign particles that have accumulated on the heat exchanging coil. The low-pressure cleaning system discharges air at a low pressure, high velocity, and a high volume in order to clean the heat exchanging coil. Further, the low-pressure cleaning system can inject a substance into the discharge air flow to aid in cleaning the heat exchanging coil.
