Refrigerant Oil: Service and Repair

OIL CHARGE-COMPONENT REPLACEMENT

When replacing certain components of an air conditioning system an oil charge must be added to the system to keep the proper level of refrigerant
oil in the system.

If there are no signs of excessive leakage, add the following amount of oil depending on component to be replaced.
Evaporator.........................................................................................................................................................................................................3 ounces
Condenser...........................................................................................................................................................................................................1 ounce

 

If accumulator or compressor are to be replaced, drain oil from component to be replaced and measure, then add same amount of new oil to
replacement component plus one additional ounce.

If the refrigerant charge is abruptly lost due to a large refrigerant leak, approximately three ounces of refrigerant oil will be carried out of the
system with the refrigerant.

Upon replacement of a component which caused a large refrigerant leak, add three ounces of oil to the system plus the amount required for the
component replaced.
