The main health hazards that can be caused by the rarity of the air conditioning unit and the drain are when there are animals that die and rot in the air conditioning duct without being noticed so that bad bacteria are hidden in the air conditioning unit ducts. Decaying animals in air conditioning units and their channels can cause bacteria to be blown into the house and inhaled by owners and can cause various infections and health problems. The increase in temperature and humidity made by HVAC units inside the AC unit helps the growth of organisms and accelerates the natural decomposition of animals and plants.
That is the reason for the importance of cleaning the aircon regularly. Airtight rooms need to be maintained so as not to cause disease. With the aircon being able to process the air for the better, it should be cleaned regularly so that the dirt that settles in the filter can be removed to minimize the presence of disease.
