DEFINITION: Under certain climate and operating conditions, a musty odor develops from mold growth in the evaporator core face. This odor is generally temporary and as climate conditions change the odor will disappear and repair itself. If the odor persists, it will be necessary to clean the face of the evaporator core with the appropriate cleaner. Leaking anti-freeze or refrigerant oil can also cause problem odors in the air conditioning system.. | ||||
