Why air conditioner not cold air?

All strive to create a comfortable microclimate. Especially for the summer period, when hot days it is difficult enough to be in a stuffy room. For this purpose, various means and methods. To maintain the optimum temperature in the room, many people install in their homes the air conditioners and split systems from different manufacturers. But in the process, these technical devices sometimes have problems. It can completely or partially fail. The most frequent problem stopped cold air conditioning. According to most experts such failures result from incorrect handling of equipment, and violations of the operation of the device.

Depending on the damage to repair the air conditioning system can both independently and using the services of qualified employees of firms engaged in the installation and maintenance of such devices. Note owners, at least once a year to produce a complete cleaning of the air conditioner, it will help to avoid most failures.

Fault

But how to establish the existence of such problems, if it seems that bad cold air? You must perform the appropriate measurement. To solve this problem, the estimated difference of the temperature regime at the entrance/exit of the cooling system. You can use the normal thermometer. Importantly, in the process of measurements to make sure it does not hit the drum fan.

Measures the temperature of the incoming air, by placing a thermometer on the indoor unit, and blows, where the flow is near the open blinds. If the set differential temperature mode reaches 8 to 12 degrees and above, the operation of the device is optimal. If this difference is smaller, it is possible to diagnose that the air conditioner is not cold, the causes must be sought in the instrument itself.

First and foremost it should be noted that installation and installation of split systems should be done by qualified professionals. If the fault occurred during the warranty period, it is better to call craftsmen installers. If the warranty has passed – you can try to make repairs on their own.

As a rule, the poor performance of the air conditioner for cooling rooms accompanied by a variety of factors, which should include the following points.

Dust drum and shaggy coat

This suggests that the air-conditioning cools as a result of contamination of the equipment. Such problems are caused by dirt clogging air filters-grids. They are located under the front panel of the indoor unit. Huge 30-day period, these items are very heavily polluted. Therefore it is necessary to clean the device.

If you ignore these events, dirt will get between the plates of the heat exchanger, which will affect the movement of air masses. Pollution will suffer and the fan. Cleaning should only be performed by specialists. Eventually, when the fan deposited a large layer of dust and dirt, it ceases to drive the air. To test its performance, you need to check the air pressure. If it is weak, then it's time to call masters at the same time they will check, and other external sources of air. A fairly common reason why air conditioning cools in early summer poplar fluff that clogged the elements of the split-system.

No freon

Any air conditioning system basically contains a special ingredient - a freon. Therefore, refrigerant – it's kind of working fluid. During the operation it begins to boil and condenseries and thus provides cooling of the interior. For split systems, which are installed in the apartments, used to 700 grams of freon. If the device has no coolant or insufficient air conditioning not cold in the right mode. All split system consists of an external and internal unit. Between these parts are connected by copper tubes which are called freon route. Master installers during the installation of the systems use the nuts and rolling the connection.

If the density of these elements is insufficient freon in the process of operation of the air conditioner will start to evaporate. Also the cause of leaks can be cracks appeared. They arise from the vibrations of the fan and the compressor. But most often such a leak can be detected in the ground connection of copper pipes to the power system in case of use of substandard adhesions. If so will evaporate about 150 grams of the substance, this will greatly affect the performance of the device. The lack of refrigerant is indicated by the following attributes:

• On the tubes appears oil;
• The air conditioner is not cooling or is not running at full power;
• The heat exchanger of indoor unit there is a hoarfrost;
• Screw on the outside unit to freeze.

So when lifting the front panel and remove air filters heat exchanger is not cold. Its upper part may be covered with frost. Therefore, to improve the efficiency of the cooling systemyou need to add the freon and remove the existing leak. After the system overheating can burn the compressor.

Too much freon

Needless to say, the consumer can face such a problem when employees of firms that produce refilling the cooling fluid split-systems, may incorrectly advise him and to obtain additional funds from the permanent filling of the device with freon. Further, the surplus refrigerant can be also the reason why the air conditioner is not cooling air. In order to eliminate leakage of freon, competent staff of specialized firms use special analyzers.

The failure of the system elements

As a result of improper maintenance of split systems was not work:

• One of the fans, so no cold air in the apartment. It can completely or partially fail to work. The problem is eliminated only by a qualified technician.
• Four-way valve. It is located on the outdoor unit and is responsible for switching hot/cold. The result requires repair or complete replacement.

• Compressor, due to inter-turn short circuit, winding holes on the housing, the inner cliff. Can also lead to failure than thermal overload relays, replacement of which is inexpensive. But if itself is broken compressor, repair is not cheap, maybe have to change the whole outdoor unit.

The failure of sensors

The Reason why no cold air, can be sensors of temperature and pressure that are wholly or partially out of order. As a rule, for security purposes manufacturers provides automatic shutdown of the system is in the failure of these elements. To resume non-working parts must be replaced.

There is a Plugged hose debris

Sometimes weak cold air conditioning, because it requires a purge using a vacuum pump with special hose. In any case, to resolve this problem, you must use the services of a wizard.

Conclusion

For the normal functioning of the cooling systems necessary to carry out timely maintenance. In the future it will allow to avoid various problems. Summon masters for cleaning all split systems must be at least once a year.

If the air conditioner is not cold, the first thing is to check the filters, as a rule, it is the most common cause malfunction of such devices. If the period of the service warranty had not yet expired, it is better to invite a specialist. In the future it will allow to avoid additional expenses. And timely servicing of cooling systems will prevent complete failure of the air conditioner. And create the prerequisites for a normal and comfortable being in the room with the purpose of solving personal and business problems.
