Generally, an air conditioner on wheels is termed as a portable air conditioner. They’re widely used in homes and offices. These units can easily be transported from one place to another and are a good alternative to window or wall units.

Portable Air Conditioners usually suck out the heat present in air and filter it by a variety of means - towards a tube or any other such device, which leads outside the general space where the air conditioner unit is in use. Then the air flows over an evaporator coil, led by means of a fan. This coil is loaded with refrigerant, which is vital in absorbing the heat present in air. When the air becomes sufficiently cooled, it is guided back into the room by means of the fan and through the air vents located at the front of the unit.
Portable Air Conditioners are versatile in a sense that they can be used to both heat or cool a room. Many portable AC’s can also be used as fans, while others can be used as space heaters.

Portable Air Conditioners are perfect for apartment buildings. They weigh anywhere between 50 to 80 pounds depending on the model you select. Portable air conditioners are more expensive than window AC’s. They are usually available with a capacity of 6,000 to 8,000 BTUs and are the most flexible option for relocating.
