Air conditioning systems play a vital role in circulating air within indoor spaces, particularly in hot climate regions like Dubai, where they are a primary source of air circulation in residential and office environments. The quality of the air we breathe indoors is directly influenced by the condition of these HVAC (Heating, Ventilation, and Air Conditioning) systems. When the air passing through the ducts is not clean, and the system is not regularly serviced and maintained, there is no guarantee of having clean indoor air in our constructed environments.
