Cleaning Air Conditioning Evaporator Core
WARNING
To avoid cuts from evaporator fins, do NOT use bare hands to brush away clogs.
1. Use a vacuum or compressed air to remove dirt from
inside the unit.
2. Blow compressed air through the evaporator fins from
the blower side (A) first as shown. Direct the air straight
into the evaporator to prevent fin damage. A nozzle
extension makes this procedure easier.
3. Repeat the previous step from the side (B) opposite
the blowers.
NOTE:
If you can’t feel the compressed air blowing through the
evaporator core, proceed as follows:

4. Protect the blower motor (A) from water.
5. Soak the evaporator core (B) with warm water using a
low pressure hose. Let soak for several minutes.
6. Blow compressed air through the core from the blower
side (C).
7. Repeat the soaking procedure until air blows through
the evaporator freely.
