This question can be answered by the user only. The user can come to this decision based on the requirements of their business or residence, wherever they intend to use it. Here are some tips to be kept in mind, while searching for a portable air conditioner.

While purchasing it for a business, see if the expenses can be shown as business costs and get tax deduction for the same. As the case can depend on the situation of a particular business, this can be decided on an individual basis only.

If the user is living in a location with warm weather for most of the year, then it makes sense to purchase a portable air conditioner for rooms with poor ventilation or frequent use. In this case, as air conditioning is necessary for most throughout the year, this would be the right choice.

For people who live in locations where air conditioning is needed only for a part of the year, this can also be the right choice. In case the user need to use an extra unit to cool down a hot room in the attic, for a shorter duration, whenever he steps in after going out, a portable air conditioner can also be used. Later, once the room temperature is brought back to normal level, the unit can be turned off and the rest of the job will be taken care of by the central conditioning unit.

As is the case with anything else available for sale, well known brands of air conditioners are usually going to cost more. At the same time, there are cheaper units available too. As the technology used in both of these machines is pretty much the same, they are both going to provide quality cooling for the room.

Most of the available brands are going to satisfy users. Look at the warranty of the machine and see if it is possible to replace it in the event of getting faulty products or parts. If the warranty is comprehensive enough and covers the air conditioner well, then it is quite safe to be purchased. Portable air conditioners can come in varied sizes and associated features. Some of them can be bigger in size, whereas some others can be really compact. Some can be energy guzzlers; whereas some others can be very economical. A user must select a machine to suit the location where it is going to be used.
