A central air conditioning system is designed to maintain desired indoor conditions throughout the year.
It provides cooling in summer, heating in winter, ventilation, air filtration, and sometimes humidity control.
Such systems are large, serving multiple rooms or entire buildings through ductwork.
They can switch between cooling and heating modes automatically.
Options like only summer or winter air conditioning do not describe its full capability.
Dehumidification is just one function, not the entire system’s purpose.
Therefore, central AC systems are mainly for year round air conditioning.
