The air conditioner vaporizer is basically a cooler, just smaller. The air passes through and gets cooled. Dust, dirt and poplar fluff are sucked in from the street along with the air. And as the vaporizer is ice-cold while the air conditioner is working, moisture condenses on it, and it was always wet.

If you turn on the air conditioner, the evaporator immediately begins to heat up and blows into the car a whole bunch of aromas and moist air. But when you start the engine again, and press the button on the air conditioner, the first few minutes, until the evaporator did not have time to cool, the air in the cabin gets very hot. As the air cools, the smells go away altogether, or become almost imperceptible. Automobile air conditioners should always be submitted to diagnosis, repair and refueling in order to enjoy a nice, comfortable ride.

The air conditioning system requires constant cleaning of the vaporizer and its air ducts.
