The advantage of the portable air conditioner is that it can be installed on its own, without the help of a rather expensive team of professionals.

Of course, this does not mean that the installation or the process itself does not need certain skills. But you can be sure that you can install the portable air conditioner yourself at home. Besides, you can save money by installing it yourself.

A portable air conditioner is an air conditioning system that delivers air to a room at a certain temperature. It does not have an outdoor unit but is placed all in one housing. The unit has small wheels for mobile movement indoors.

The air conditioner has a compressor, which is a motor – it is not carried outdoors, but is located inside the room. The portable air conditioner differs from standard split-systems and has both pluses and minuses.


The portable air conditioner has standard functionality:

  • Bringing the air temperature to a certain temperature
  • Desiccation
  • Normal ventilation
  • Heating

Working principle of the portable air conditioner

To remove the warm air produced by the compressor, the air conditioner is equipped with a flexible corrugated pipe. It is routed outdoors. For obvious reasons, the warm air must be evacuated in a well-thought-out manner. Otherwise, the entire operation of the portable air conditioner will be useless.

The drain system of the portable air conditioner is discharged in several ways:

  • To a special collection of condensate (it must be emptied periodically).
  • It is led into a special pipe that ends in a container which must also be emptied.

In other words, the air conditioner is very like popular split systems. But there are differences, advantages, and disadvantages, we will talk about them below.

It may seem to some that the installation of a portable air conditioner is a simple matter, but it is not so simple at first glance. Of course, the installation of a portable air conditioner does not compare to extensive work. Such as that required for split system installation, but the basic experience is required.

The feature of the portable air conditioner is that many models are sold with a mounting kit. It is designed for installation on room windows. Thus, the easiest and most logical way to install the portable air conditioner is to take warm air outdoors.

The installation kit for any model of the portable air conditioner is of the same type. The window kit for the portable air conditioner consists of the unit itself, a corrugation, a plastic outlet tip, and housing for fixing it.

The method is like the previous one, but more efficient. Instead of a stopper, a narrow plastic insert is used, usually supplied with the air conditioner. A corrugated pipe is connected to the segment. To put the portable air conditioner out of the window, you need to open it and place the insert in the vertical opening.

What is needed to install the portable air conditioner in a room with no housing to fix it:

  • Dense plastic sheet, at least 1 inch thick. This is necessary to create a certain barrier between cool indoor air and warm outdoor air.
  • A construction saw for plastic to cut through hard material. A normal metal saw is also suitable.
  • Special paint tape or tape to fix the cut sheet to the window frame.
  • Sealer or mounting foam to ensure water and airtight.

Portable air conditioner disadvantages

The air conditioner must be monitored periodically, or rather the level of condensation (water) in the container. If it overflows, the portable air conditioner will automatically shut down.

A portable air conditioner is a bit noisier than a split-system, as the compressor is inside, not on the street, as at usual air conditioners. The level of noise can be compared with a kitchen extractor hood.

For the operation of the split air conditioner, it is necessary to exhaust hot air outside. This is done with the help of a corrugated pipe with a diameter of more than five inches, which goes in the set. This creates some discomfort. It is also not recommended to extend the pipe, otherwise, the capacity of the portable air conditioner will be lost.

A portable air conditioner with its properties is not inferior to wall devices, and the possibility of its own installation and compactness bribe many. When the need for cool air disappears, the air conditioner can be hidden until next summer. Besides, the choice of split-system will save money. Do not be afraid to experiment and enjoy your rest.
