In our enlightened age, when the installation of any unit is repeatedly and step by step described in hundreds of thematic sites on the World Wide Web, it is quite possible to install an air conditioner yourself if two conditions are met. First, a person should not be afraid of heights when it is necessary to mount an external unit of air conditioning, for example, on the seventh floor. And secondly, the home wizard must scrupulously follow the advice, recommendations and instructions of the professionals.
Today in the article we will look at how to install the air conditioner correctly, choosing the best time, place and tools for this.
How does air conditioning work?
The mechanism in question resembles a refrigerator, only the latter keeps the cold produced inside, and the air conditioner gives it out. Otherwise, the principle of operation of both units is similar. 
Liquid refrigerant in the form of, for example, freon under pressure is supplied by a compressor located in the external unit of the air conditioner to the expansion chamber located in the internal unit. There, the refrigerant boils up, starting to rapidly absorb heat in pairs.
The expansion chamber, respectively, is cooled, and moisture from the ambient air begins to condense on it, which is collected in a tank, from which it is then removed outside the system. This is the same water, the thin trickles of which we usually observe arising from the tube of a working air conditioner.
The refrigerant turned into a gas expansion chamber by a compressor is pumped out of there and chased under pressure into a condensate chamber. Along the way, the refrigerant turns from a gas into a high-density fog, while heating up. Then it enters the radiator of the condensate chamber, where it is cooled by a fan and becomes liquid again, after which the process cycles are reproduced again and again. 
Did you know? The very first conditioner, created in the USA in 1902, was not intended to cool the air in the printing house, but to counteract the moisture that adversely affected print quality.
The best time to install
There is an opinion that air conditioners, or, as they are called, split-systems, are best installed at any time of the year, except for the summer, when the demand for them is maximum, and the prices for their installation, respectively, are the highest.
In the case when a person wants to install an air conditioner on his own, this aspect of the problem is his last concern. Quite different questions come to the fore.
For example, the indoor unit of the unit can be easily mounted at any time of the year, since the process takes place indoors. But as for the outdoor unit, then winter blizzards and frosts can make serious amendments to the installation work, especially if they occur at high altitude.
That is, comfortable working conditions come to the fore here, and not so much in safety issues as in the quality of the installation: in the cold it is quite difficult to achieve. 
Do-it-yourself home renovation is a creative matter, and it allows you to save money, so it’s helpful to know how to remove paint from walls, how to wash off whitewash, how to glue wallpaper, how to install plumbing in a private house, how to put an outlet, how to make a plasterboard partition with a doorway, how to install a light switch, how to install a flow water heater, how to sheathe walls with drywall.But even if it succeeds, an even more complicated problem immediately arises. The fact is that in severe frost it is almost impossible to carry out a high-quality vacuum system. That is, the frozen water inside it in the form of ice will remain there, and then, having melted, it can disrupt its flawless work.
There are still some technical problems that arise when installing an external unit in the cold. Therefore, professionals who still mount the system at sub-zero temperatures, start up the system and set it aside for warm days. And if the customer insists on an immediate launch, then the masters take from him a receipt that he will not have claims against them in case of abnormal operation of the system after a cold start.
So the air conditioner can be mounted and run at any time of the year, but on condition of a positive temperature. 
Required materials and tools
The following materials and tools will be sufficient for installation and installation of the system:
- bracket for outdoor unit;
- two copper tubes of the required length with a section of 6.35 millimeters and 9.52 millimeters, covered with rubber insulation, with factory-flared ends and nuts attached to them;
- corrugated drainage hose;
- four- or five-wire electrical cable with a cross-section of at least 1.5 square millimeters;
- vacuum pump;
- perforator with a drill of at least 45 millimeters or with a diamond drill;
- gauge manifold;
- wiring tester.
Choosing a place for installation
Indoors, the unit of the unit is recommended to be positioned so that the cold air flow does not constantly go towards the people there. Usually the internal element of the air conditioner is placed on the sides of the windows.
The optimal distance from the unit to the ceiling is 30 centimeters.
Important! The distance between the ceiling and the air conditioner should not be less than 10 centimeters.The main requirement for the external unit - it must be available for safe service at height. Therefore, the best option here is a wall on the balcony or a non-glazed loggia. If this is not possible, then the external module must be installed directly below the window so that the master has access to all parts of the unit.
And one more essential requirement: the channel in the wall along which the highway will pass should be done with a bias towards the ground. 
Upon detailed consideration of the process, you can build a cellar with ventilation, a sheepfold, a chicken coop, a veranda, a gazebo, a pergola, a brick fence, a blind area of the house, a smokehouse of hot and cold smoking, a concrete path.
Step-by-step instruction
The installation of a split system consists of several stages, during which internal and external blocks are mounted one after the other, and then they are connected with the help of a main line.
Mounting external unit
When complying with safety regulations, installing an outdoor air conditioner module is not particularly difficult:
- With the help of the construction level it is necessary to mark the future holes and then drill them out.
- Insert the mounting bolts down into the brackets with the heads and fix them with plastic washers.
- Using anchoring, you need to install the brackets, then you need to place the external module on them, aligning the holes on it with the bolts, after which the fastening nuts should be well tightened with a cap wrench.
In an effort to decorate the space around the house, pay attention to the possibility of making a waterfall, alpine slide, fountain, wattle fence, flower bed, trellis, rose garden, mixborder, dry stream.
Mounting the inner panel
Prior to this important matter, it is necessary to carefully study the manufacturer’s operating instructions, which indicate the particular installation features of this particular model.
- Next, you need to remove the perforated mounting plate located on the body of the unit, attach it to the wall where the internal module of the device will be located, and mark the places for future mounting holes.
- After that, using a perforator, a channel with a diameter of at least 5 centimeters should be drilled in the outer wall, through which the trunk line will pass. The channel should be in a wall with a slope of 5-10 ° towards the street. Otherwise, the condensate will not go outside, but will accumulate inside the unit.
It is recommended to insert a special plastic sleeve into the drilled channel ... 
- Then drill the mounting holes in the wall and fix the mounting plate with dowels and screws.
It is recommended to insert a special plastic sleeve into the drilled channel ... 
Important! The indoor unit of the air conditioner should be strictly horizontally, therefore, when installing the mounting plate, it is necessary to use the building level.
Electrical wiring
On the outside and inside of the blocks above the pipe connection ports, there are removable plates under which connectors are hidden. You should connect the previously stripped cable ends to them in full accordance with the scheme, which is present in the instructions. 
First, the cable is connected to the indoor unit, and then, when the trunk with the cable is formed and pushed through the channel in the wall to the outside, the cable ends, again in strict accordance with the scheme, are connected to the external module. 
Even the weakest split-system requires one and a half kilowatt of electricity. For her, you need to make a personal wiring with automatic shutdown.
Pipe laying
A purchased installation kit of copper pipes that have been expanded in the factory should be removed from the package and the ends should be tightly closed with an adhesive tape on one of their sides in order to avoid moisture and dust from entering the pipes.
And the remaining ends must be connected to the communications located on the rear wall of the indoor unit. 
Then, from these pipes, as well as from the electrical cable, you should create a kind of bundle, which must be very carefully wrapped with PVC tape. A corrugated drainage pipe for condensate drainage is also laid along this harness. 
Important! In no case can not twist the tube between them.During the next operation without an assistant can not do. Together with him you need to push the harness through the channel in the wall to the outside, and install the indoor unit on the mounting plate pre-fixed on the wall. This is done very easily - special latches clearly fix the connection.
Some craftsmen decide to cut pipes and flare their ends independently using specially purchased flare sets. In addition to complicating the installation process of the air conditioner, it also significantly increases the risk of subsequent refrigerant leakage from the system.Evacuation system
Using a vacuum pump, the system should be thoroughly cleaned from moisture, dust and other undesirable elements. For this, the lateral hose of the gauge manifold should be connected to a tube of larger cross section, and the middle one should be connected to the pump. All this is done only with closed taps.
Then it is necessary to open the valves and turn on the vacuum pump, in the first 10-20 seconds, releasing air from the pumping nozzle. 
Air conditioning should be cleaned with a vacuum for at least 20 minutes. After the termination of evacuation it is necessary to observe the manometer about 20 minutes. If his arrow remains stationary, then everything is in order, and if the pressure starts to fall, then the system is not tight, and it should be rechecked using soap suds at the joints of the pipes.
Did you know? The camel is the real live conditioner. He breathes in the hot and dry desert air, which, passing through the camel's moist nose, cools down. But the most striking thing is that dry air comes out of a camel, which is 9 degrees lower than the animal's body temperature.
Air conditioner refill
Split systems when leaving the factory were initially charged with refrigerant located in the outdoor unit. In order to fill the entire circuit with freon, it is necessary to open the valves alternately on both sides with a hexagonal key - liquid, and then gas. 
As a result, the entire circuit will be filled with freon. 
Testing
To check the performance of the installed air conditioner, it is necessary to turn on the split-system automatic disconnector, after which it must enter the test mode on its own. If this does not happen, you can start the test mode from the remote control. When the air conditioner is properly installed, the testing process should start without problems. 
How to care for equipment
As it was possible to be convinced already at its installation, the conditioner is rather difficult household appliances which need systematic leaving.
First, you should regularly wash the plastic filters that are in the indoor unit. This should be done at least once a month, and when the room is dusty - and more often.
In addition, even with the highest quality installation and installation of a split system, it inevitably loses up to eight percent of the refrigerant annually. Its lack can lead to jamming of the compressor, therefore at least once in two years it is necessary to compensate for the loss of freon in the apparatus.
The instructions of each split system indicate the temperature below zero, below which this model cannot be used.
In the presence of certain technical skills and in the absence of fear of height (in case of need for installation on the upper floors of a high-rise building), the house craftsman will be able to install the air conditioner on his own, without asking for help from expensive professionals.

Should I install an air conditioner myself: reviews
It’s just not rational in effort and time spent doing it yourself. As I wrote earlier. In a bunch of everything to collect, on the installation of one kondeya, it will take a lot of time, for money, too, not quite justified. Installation will be longer than three times.
Recently mounted with Verya outdoor gear and visor. Did it on the second floor. On the first floor the track was thrown out. At the time when the visor was marked up, the boys arrived at the installation of outdoor advertising from the first floor.
When fastening the visor, they began to mark under the brackets. In general, mounted outdoor fully, starting with the markup. Gathered faith tool and went out into the street. During this time, they just screwed the box to the brackets ... Honestly, together with the drivers, I didn’t expect such a big difference.
When the hand is full of work happens like this:
