Portable air-conditioners can be taken wherever you go since they are light weight and hence easy to take along to the room of your choice in the home or at office. They are rated in British Thermal Units and calculated in BTUs like 8000 BTU = 200 sq. ft. or 10000 BTU = 400 sq. ft.

Portable Ac are meant to dehumidify air and are used in place of fans or water coolers. Some models are used for both purposes for cooling as well as heating whenever required. It is better to choose a model that can be used for all purposes so it will be in use throughout the year.

One great feature of a portable air conditioner is that you can position it in any area of your home or office that would benefit from cooling air. You are not stuck with a permanently mounted unit that cools one area very well and outlying areas poorly. With a portable model, you can focus the cool air where you need it most. Imagine a bedroom in cool comfort even though the temperatures are sweltering outside, because you can roll your portable air conditioner into your bedroom. The next day, your portable unit can move with you into your home office, covered outdoor living space, or any other room in your home where you are and where you want it cool. In an office setting a portable room air conditioner can be just the thing you need to keep your server and other hot-running electrical equipment operating at optimal levels because the room is kept in the correct temperature range.

Another reason why small portable air conditioners make an excellent investment is that you only pay for what you use in terms of air conditioning. A large permanent air conditioning unit will cool large areas of space, including rooms that you are not occupying. This is money down the drain, because you are getting no benefit from unused rooms that are cooled. Instead, focus your air conditioning on the spaces that you are using, and enjoy the benefit of cool temperatures yet only pay for what you use, where you use it.

Now as the name suggest the device is movable and small. Essentially an AC is considered as a home appliance which comes in various shapes and sizes. It is able to regulate the temperature and humidity inside a closed area like a room or a car for making the stay in it comfortable. It is a device which shows that we want to be comfortable and the desire to alter our environment.

Now what are the advantages of such a portable air conditioner? Well first is obviously the size of the device. Now the size allows placing the device where you want it. For example you need not fix the bed in the direction of the AC on the wall or the window. The s-portable one allows you place the bed as you want in the room because the size and mobility of the device gives you the freedom to do so.

Portable air conditioners are a modification of the ordinary fixed air conditioners that are mounted in a window or on a wall.

They offer convenient replacement of ordinary AC units for users who do not have enough space to fit window units, or for those in a rented house where they cannot punch a hole in the wall. Portable AC's are mobile and can be carried anywhere based on the requirement. They do not have to be mounted in the wall however there are certain things that need to be kept in mind while using portable air conditioners.
