Which of the following is NOT a characteristic of air conditioning?

Focusing solely on temperature control is not a characteristic of air conditioning because modern air conditioning systems are designed to manage a range of factors beyond just temperature. While temperature control is a core function, effective air conditioning systems also regulate humidity levels, enhance air cleanliness by filtering out pollutants, and ensure the even distribution of conditioned air throughout a space. By addressing these multiple aspects, air conditioning systems create a comfortable and healthy indoor environment, demonstrating that their functionality extends well beyond just controlling temperature.
