Air conditioners that can be made to move from one place to another on casters are called Portable Air Conditioners. These can be as large as window units, but they can be easily transported on their wheeled casters. Portable Air Conditioners find great use in industries, warehouses, temporary businesses, and more.

Some industrial warehouses are so large that they cannot be cooled by a single central cooling unit. Such spaces rent Portable Air Conditioners for their spot cooling needs. As their workers or machines move, the air conditioners can also be made to move along with them. Several machines in factories need such spot cooling. Even places where many computers are installed require cooling for their optimum use.

Portable Air Conditioners are specially designed for rough use; hence, their capacities are higher than the usual ones. Portable Air Conditioners with cooling capacities of 3.5 to 60 tons can be rented. They are available with both Freon and evaporation technology. Air conditioners that work on evaporation principles are more expensive to rent than Freon ones.

Portable Air Conditioners are also rented by organizers of functions and events such as weddings, live performances, football matches, and more. Rented air conditioners are placed at strategic positions so that there is an average cooling throughout the place. Once the program is finished, the air conditioner can just be wheeled away to the next location.

Vehicles on the move sometimes rent Portable Air Conditioners if they require cooling especially when there is some shipment aboard that requires cooling, such as perishable foods. Water transport vehicles such as boats and ships also find it easier to rent a Portable Air Conditioner for their cooling needs.

One can rent Portable Air Conditioners both on a long term and a short term basis. Factories require long term rentals their rentals can extend to a couple of months or even years. But social events may rent Portable Air Conditioners for a day or so. Depending on the type of air conditioner rented and the period for which it is rented, the cost may range from a few hundred dollars to a few thousand dollars.
