DIY air conditioning repair

Climatic equipment plays a big role in creating a comfortable home environment. Repairing air conditioners in the event of a breakdown is easily carried out by one's own hands, since these devices are quite simple to operate and operate.

Diagnosis of problems

In household ventilation systems, a decrease in work efficiency is immediately felt. If some signals about the upcoming breakdown of home air conditioners can not be immediately noticed, then the deterioration of work is noticeable immediately (especially in the hot season). The main types of malfunctioning air conditioners:

1. Water is dripping from the air conditioner or condensation is collecting on the back wall. Vaporization in the device indicates a malfunction of the drainage channel, which should remove water from the device. This problem can have an unpleasant outcome - with frost on the walls of the drainage, ice stagnation forms, which will cause equipment breakdown;

   

2. Bad smell during operation. This happens if the device does not turn on for a long time or is very dirty. It is worth paying attention to the kind of smell. If it stinks of burnt plastic, then the wiring or some internal part may burn, if it is simply stale, then this is a problem of the filter clogging;

3. Uneven distribution of air flow. For example, he blows heavily on the ceiling and is not powerful enough towards the floor. Here the cause of the malfunction lies in changing the bending of the blinds. To control the draft in air conditioners, a special grill is used, which, depending on the settings, can change its frequency and angle;

   

4. The device does not turn on. Check mains and power wires;
5. Low cooling temperature, whistle during operation, other unpleasant and non-standard sounds. For the operation of domestic and industrial air conditioners, it is necessary to use refrigerant - freon in the device, which helps to cool the compressor with intensive ventilation of the room. This failure is critical for both the compressor and the engine and the radiator of the air conditioner. In the presence of this malfunction, it is better to immediately take the equipment for repair to a service center;

   

6. Incorrect temperature settings, malfunctions, interruptions in time and mode control. Most likely, the problem lies in the malfunction of the split-system boards. You need to check their contacts and the condition in general. Diagnosis is carried out on special equipment, so it is more expedient to take the device to professional workshops.

Separately, it must be said about the breakdown of floor-mounted domestic air conditioners. A very important role is played by the correct installation of HVAC equipment. If the installation was not carried out on a flat surface, then the drains will clog the first, and then the radiator and engine will malfunction. The air conditioner will begin to buzz during operation and accumulate condensate, after which its repair will be almost impossible.

The easiest way at home is cleaning and urgent repair of the air conditioner radiator. Externally, the radiator of the split system resembles a very shallow mesh, which is located under the front panel of the device. Due to the fact that it is constantly exposed to dusty air, a large amount of litter from outside accumulates on the grid, which gets into your home during work. In addition, the equipment also dusts during idle periods (winter and autumn), which also causes dust to appear on the radiator.

To own clean and repair the air conditioner, need to:

1. Remove the panel from the device. It is attached to threaded connections, they are removed with a screwdriver or wrench (depending on the brand). For some window air conditioners (Mitsubishi, Hitachi or Daikin), the panel is also secured with hidden locks;

   

2. Under it are the first air filters, through them passes a stream of air from the street and from the house. Therefore, you need to remove and soak in warm water and soap for 30 minutes. During this time, fat deposits and dust will stick off from them, and pathogenic bacteria will also be destroyed;
3. Below them is a rotary fan. It is made in the form of a roller and must be cleaned, because this particular part helps to distill the air. Its maintenance consists in wiping the blades with a damp cloth soaked in soapy water;
4. Next, you will find yourself in filters through which air flows from the external compartments to the internal ones. These parts are cleaned with a roller moistened with water and soap, you can buy a special tool or use a rag wound on a long tube.

Most often, warranty repairs do not mean cleaning radiators of air conditioners, so the work will have to be done independently. It is advisable to repeat the process once every six months to ensure the best effect.

Instructions on how to clean the heat exchanger of an air conditioner Panasonic (Panasonic), Samsung (Samsung), HLW and others:

1. It is necessary to remove the front panel and remove all parts of the external compartment. You need to get into the internal one, the heat exchanger is located there;
2. There are several ways to clean. For example, many even professional craftsmen simply purge the radiator with a vacuum cleaner. If you do not have this device, then you can walk on it with a soft brush;
3. To check its performance - dip the part in a basin with soapy water. If bubbles come from somewhere, then the radiator needs to be sealed.

With rare use of the air conditioner, or, conversely, after a very intensive use, many owners notice that water is dripping from under the front panel. The problem is in clogged drainage pipes. What to do:

1. Repair of air conditioning hoses is carried out only in the warm season, in extreme cases, at positive temperature, otherwise it will be inappropriate;
2. If the problem was noticed after the winter season, then first you need to warm it carefully with warm water and a rag - it is likely that an ice plug has formed in the pipe;
3. If the malfunction was detected in the middle of the working season, then you need to blow the pipe. To do this, you can use special compressors that are discharged to the internal outlet of the tube or liquid. Read the instructions in advance if cleaning solutions can be used in your air conditioner.

But the most dangerous problem, which requires urgent repair and may affect the operation of the air conditioning compressor or its clutch, is refrigerant leakage. The main insidiousness of the malfunction is that it is very difficult to detect. Not even all professional workshops provide such a service. Signs of a leak:

1. Noise at work;
2. Decrease in cooling efficiency;
3. Sudden changes in temperature.

Before starting repairs, you need to detect the leak. There are several ways to do this. The simplest is, again, using a soap solution. It is necessary to lubricate the pipes of the refrigeration circuit with a special soap agent (you can also use the usual 1: 1 solution, but its effectiveness is lower), and monitor where the bubbles appear.

In some brands, a liquid is added to freon, which glows under ultraviolet rays. Of course, you will need to arm yourself with a UV lamp, but this is the fastest and most effective option. It will not work to repair high and low pressure pipes on their own, moreover, if you do not find a problem in time, repair will be more expensive than the cost of the equipment. Therefore, we recommend contacting a service center with this leak immediately.
