To change the filters, you will need to carefully lift (or
The replaceable filter for coarse air purification is a fine mesh and can be easily dismantled.

By measuring the temperature and airflow rate at the outlet of the indoor unit of the split system, you can diagnose a number of malfunctions (for example, freon leakage or fan failure)
To flush the drainage system from dirt and calcium deposits, pour in a little special cleaning fluid
During preventive maintenance, the front panel of the indoor unit is washed under running water / If it is not possible to use water, the unit panel is cleaned with wet wipes for plastic
Dry the filters after washing.
To transport the necessary equipment, serious service companies have their own climate-friendly ambulances.
Measurement of pressure in the refrigeration circuit allows you to detect possible freon leaks
Freon leak check at joints
Checking freon leakage at the outlet of the indoor unit
In the ceiling unit, as well as in the wall unit, the drainage is flushed with a special compound
freon leak check
What do we usually do when we bring home new appliances? We plug it into the outlet, and it works without requiring any special attention. Well, except that from time to time you have to dust off the TV or change a burned-out light bulb in a chandelier. FROM
The simplest, but absolutely necessary air conditioner maintenance operation, which you can carry out yourself, is to regularly clean the mesh filters of the indoor unit (hereinafter we are talking about the most common types of air conditioners currently
Naturally, inhaling air driven through a layer of dirt will not add health to the inhabitants of your house. In addition, oddly enough, when using an air conditioner with clogged filters, your wallet will unnecessarily quickly lose weight. As dust accumulates on the filter, the amount of air passing through the evaporator decreases and the cooling capacity of the air conditioner decreases. Severe pollution leads to a violation of the operating modes of the refrigeration system and even to clogging of the drainage system with whole lumps of dust. AT
Clean the filters of the indoor unit with a brush, then wash with soap and warm water. At the same time, you can take with you into the bathroom and the front panel of the indoor unit (if it is wall-mounted). After the parts must be allowed to dry, if possible away from direct sunlight and heating devices (after all, the parts are made of plastic). The sequence of removal and installation of filters is indicated in the instruction manual, which remained with you after the workers who installed the air conditioner left.
In addition to mesh air filters, which are available in the indoor unit of each split system, others are often used in domestic air conditioners. For example, for fine air purification, an electrostatic filter is often installed that captures pollen and dust particles up to 0.01
However, manufacturers are constantly improving the air filtration system. One of the most modern solutions in the field of cleaning and deodorizing the air in an apartment are zeolite filters. They are more efficient than simple carbon ones: the zeolite filter completely purifies the air in the room in just 30 minutes.
The lot of professionals
Of course, air conditioner maintenance is not limited to washing filters or replacing batteries in the remote control. Air conditioner
Look at the windows of your city apartment. Every spring they have to be washed, and you probably saw how much dirt accumulates on the windows, which means it gets into the condensers of the outdoor units, through which large volumes of air pass with all kinds of impurities and foreign inclusions. Radical measures will also be needed to clean the outdoor units from poplar fluff, burning and other street dirt. After all, a contaminated capacitor
Be careful. Do not let the service crew clean the outdoor unit with a portable pressure washer
An important area of work of the service department is also regular monitoring of the compressor operating modes and checking the tightness of the freon circuit. Freon leakage, as a rule, occurs quite slowly and therefore is imperceptible to the owner (by the way, the normalized loss of 6 to 8% of the refrigerant per year is generally inevitable
There are several methods for checking and correcting the charge of the refrigerant. A leak can be detected, say, using a special device
The list of services for which you pay money to service specialists also includes electrical testing. To
Contacting the service department will help you get an independent assessment of the quality of installation work and make sure that the climate system is working after finishing the premises. Often, at the same time, it is possible to identify errors and shortcomings of installers that are dangerous for the air conditioner (for example, for some brands of air conditioners, the absence of a stabilizer that protects the compressor and control automation from power surges in the supply network can be considered a mistake) and builders-finishers. The latter can damage the lines of the refrigeration circuit, electrical communications, clog the drainage hole and the air duct with debris and dust.
Most of us have a rather vague idea of the rules for operating air conditioners, although they are described in detail in the instructions attached to the device. Therefore, do not be afraid to ask questions to representatives of the service company. They will surely tell you many instructive stories. For example, about using the air conditioner in winter. The fact is that it is possible to turn on an air conditioner that is not adapted to cold weather only at an outside air temperature of at least
Warranty and service are not the same
Warranty and service
The automation system is practically maintenance-free. However, it is certainly worth talking about its role in relation to the procedure for servicing a domestic air conditioner. The fact is that good microprocessor control often allows the user to save on service maintenance. For example, on split systems from MITSUBISHI ELECTRIC,
Many progressive manufacturers provide various mechanical or electronic protection units in air conditioners, the use of which can save the device from damage as a result of violation of the operating rules. And
Among the technical highlights that allow you to delay the call to the service center are high and low pressure switches, which are standardly supplied, for example, with household air conditioners of the CARRIER model range. The high pressure switch turns off the operation of the device if it is outside
Some companies such as CHOFU, HITACHI,
How to choose a service company
The problems associated with the microclimate in your home can only be qualitatively solved by companies that have at least two years of experience in the air conditioning service market. Such companies, as a rule, offer a full range of services (from
It is impossible to provide a high level of service at bargain prices. The service department needs to maintain its own fleet of cars, pay salaries to specialists, etc.
When concluding an agreement with a company for the maintenance of an air conditioner, make sure that the text of the document contains all the services agreed earlier, as well as the timing of the planned work.
It is best if the specialists of the service center have been trained in the training centers of the manufacturers of the equipment they service.
When choosing a service center, ask to familiarize yourself with a package of documents regulating the work of the organization. AT
- certificate of the manufacturer of the serviced equipment, confirming the right of the service center to work with a specific trademark (certificate of the Authorized Service Center);
- certificate of conformity for «Installation, repair and maintenance of air conditioners»;
- certificate of conformity for «Repair of household electric heaters and fan heaters», which is issued by the service certification body of the All-Russian Research Institute of Certification (VNIIS);
- a document on checking the accuracy of the readings of the instruments used by the service center specialists in the course of their daily work.
