It is typically larger and more powerful than residential AC units, and is designed to provide cooling and ventilation for larger areas. Commercial AC units are often used in office buildings, factories, warehouses, and other large commercial spaces. They are also used in some residential buildings, such as apartment complexes. Commercial AC units are designed to provide cooling and ventilation for large areas, and are typically more energy efficient than residential AC units. They also come with a variety of features, such as air filters, temperature controls, and humidity control. Commercial AC units are designed to be more reliable and efficient than residential AC units, and are often more expensive. However, they can provide a great deal of comfort and convenience for businesses and their customers.
