Most portable air conditioners cool and dehumidify rooms, as well as use air purification features. Installation for portable air conditioners is not permanent. They can be moved around on wheels or castors, and can also be packed up for easy storage. They are very energy efficient, thus saving money on energy bills. With today's technology, which includes ultraviolet lighting, they are constructed with carbon air conditioning filters to remove odor, collect dust, and prevent mold. They are also equipped with digital thermostats and automatic timers that can be set from 1-12 hours.

Portable air conditioners are the perfect cooling product for: residential homes, computer/server rooms, small offices, university classrooms, construction sites, hospitals, retail companies, disaster recovery sites, and industrial locations. Additional features include quiet operating technology, and an LCD display with remote control. These convenient conditioners have ionizers that release positive and negative ions into the room, as well as an automatic oscillating louver which directs air throughout the room evenly. Installation parts include a durable, yet flexible, exhaust hose and window adapter kits. Industrial portable cooling conditioner designs eliminate the old water tank or tray that had to be emptied. Today, they contain a built-in condensation disposal system, sending water through the exhaust hose.

Industrial or commercial models are more reliable, and are built for easy installation as a drop ceiling model. Portable cooling conditioners ideal for businesses are those that will automatically restart after a power failure. This feature ensures that computers and servers are protected from heat damage, because of their precise automatic temperature controls. They improve the room environment where circulation and ventilation is poor, and they increase the room's energy efficiency.

The new and improved ceiling mounted conditioners utilize the latest engineering features to keep server rooms, and other small spaces that contain high heat temperatures, safe and cool for products and equipment. Portable ceiling mounted air conditioners are built "green," easy to program, and can be installed and moved simply and quickly. They are free of chlorofluorocarbons ("CFC’s"), which means they do not emit dangerous ozone damaging gases.

For small rooms like in the home, vent-less portable cooling conditioner units are placed by the window for the exhaust pipe. The cooling temperature is exhausted through the pipe, and is equipped with a thermostat to adjust the temperature as needed. They also come in a fun variety of colors and designs to match the interior of homes or small offices. Vent-less portable air conditioners, like most portables, save greatly on power and electricity bills.
