A portable air conditioning unit is a smart option when cooling a non air conditioned space is desired. The garage is a great location to cool during the hot summer months and keep comfortable while making repairs on small items, working on lawn equipment and maintaining autos. Working in uncomfortably hot spaces reduces productivity and many home based jobs are run from the extra space available in home garages. A portable unit can be placed in a window or customized to fit in a wall space that is cut to a specific size.

A hot attic is another spot that can be cooled with an inexpensive and efficient portable cooling unit. Many homes are afforded hardwood flooring in attics that make perfect areas for craft and art work and home office units. A cool attic also helps to maintain a comfortable temperature in the living space within the home. While storing items and organizing this upper level space, more work can be accomplished when not battling hot temperatures. Many households cannot afford whole house central cooling systems and opt for several portable units that can be used only when the rooms are occupied. This is a great money saving tactic when electing to cool only the rooms in the home that are being used.

Vacation homes from the mountains to the shore are in need of indoor cooling from time to time. During the summer months, the cool mountain nights lend to high temperatures at day break and the offshore breezes give way to the stillness of sweltering heat waves. A portable air conditioning unit is the smart choice for these occasional periods to relieve a summer day's heat. One unit can accommodate an entire house when purchased to cool the square footage of the intended space for cooling.

When building a new home, a central air conditioning system may be too expensive and several portable units can be purchased for a fraction of the price of a central system, while producing the same desired cooling effect. The size of any structure can be matched with one or multiple portable air conditioning units for comfortable indoor temperatures. These units have made huge advancements with minimal noise while running and adjustable extensions to ensure a snug fit to keep cool temperatures in and hot temperatures out. Many households rely on one or more portable air conditioning units as back ups when Freon is exhausted in the middle of the summer and maintenance calls take days.
