How to disassemble an air conditioner? How to disassemble a household split system and clean it yourself? Cleaning the air conditioner with your own hands: the process of cleaning a home air conditioner, operating recommendations How to disassemble the LG split system

There is a lot of information, articles and videos on this issue on the Internet; we will try to summarize with you a little and look from the technical side at the process of cleaning and servicing a split system (air conditioner) both with our own hands and when calling specialists.

To begin with, I would like to answer a question that worries everyone and everything.

How often should you clean your air conditioner? There is no definite answer; it depends on the operating conditions and habitat. Air conditioning in an apartment is one thing, and air conditioning in a Bar, Cafe or Food Unit is another thing. Let's assume that we have an ordinary household air conditioner in an apartment, with a standard power of 7-12 kbti.

We answer: The air conditioner needs to be cleaned and maintained annually!

What is proper air conditioner cleaning?

The second question is what is meant by cleaning the split system (air conditioner). Cleaning the filters of the indoor unit can also be called cleaning, but such “cleaning” is of little use. Cleaning an air conditioner (split system) is, first of all, cleaning the heat exchangers (evaporator and condenser) of the indoor and outdoor units, cleaning the fan, cleaning the squirrel wheel, cleaning the drainage system.

How to properly clean split system filters?

Cleaning split system filters should be taken by default; filters must be cleaned every two to three weeks. This sweet girl will show you how to do it correctly.

Well, how to clean the split so that it can be of real use?

It is difficult to do this without a steam cleaner and a high-pressure washer, but you can do it with improvised means; it is advisable to do such cleaning before each summer season.

How to disassemble and clean your home air conditioner yourself

I found a very good video on the Internet on how to properly clean the indoor unit of a split system yourself, watch:

What is the difference between cleaning and servicing an air conditioner (split)?

Maintenance is carried out by specialists using a steam cleaner and a washer, which, in principle, you can do yourself, but the key difference between maintenance and cleaning of the split system is that specialists measure the freon pressure in the system, and, if necessary, refill the required amount of freon to split cooled at an acceptable level. Diagnostics of electrical and installation connections is carried out automatically. In other words, cleaning the split system is part of the work on servicing air conditioners. I found a decent video, good guys, they explain everything in detail, watch it:

After watching these videos and reading the article, I think you all have become a little clearer about what kind of animal “cleaning air conditioners” is and “what they eat it with.” And you will decide what to do, clean your split yourself, or call specialists. But I would like to summarize all of the above:

1) You can clean the air conditioner filters yourself every 2-3 weeks

2) Cleaning of the indoor unit (condenser, squirrel wheel, drainage) must be carried out monthly on your own or by calling specialists

3) Maintenance (comprehensive cleaning of internal and external units, refilling with freon) must be carried out once every two to three years calling the specialists

Numbers and prices

The average cost of cleaning a split system in Krasnodar is 1300-1500 rubles per season. This includes cleaning the indoor and outdoor units of the air conditioner, with disassembly. With a steam cleaner and a sink, sometimes just with a steam cleaner. In good services, during the high season there is usually a queue of at least 2-3 days. There may be more, but depending on your luck.

The annual loss of freon (microcracks and microleaks) set by the manufacturer is 5-7%.

Refilling with freon, if necessary, is not included in the cost of cleaning, and can cost 500-1000 rubles additionally, depending on the amount of freon.

Disassembling and cleaning the indoor unit of the Panasonic P.S. split system. Don't forget to lubricate the impeller bearing...

Servicing the indoor unit of the air conditioner…

Hi all! At the request of my friends and accomplices in general, I want to write a post about the service of air conditioners, because this is already relevant at the moment (I hope the moderators will be understanding)! The fact is that consumers are often misled by offering them service for their air conditioner ANNUALLY!!! There is no need to do this, because everything depends on the degree of pollution of the room where the air conditioner is located!
How to understand that cleaning is already inevitable? Let's take a look at the process of cleaning the indoor unit, perhaps you can perform this operation yourself:
So we have a regular internal block:

Below, so as not to stain the repair, we glue the film onto ordinary masking tape:

Open the lid, remove the mesh filters and rinse them under running water (this can be done at any frequency, but at least once every 2 months!)

Now we remove the entire upper part of the case, along with the cover...

We unfasten the bathtub (through it the condensate enters the street)…

and then enjoy the terrible spectacle! Here we can already understand what we breathe including a clogged air conditioner...

We turn on the remote control to 22-25 degrees (don’t turn it on minimum... never in the heat, not a single air conditioner will give you 16-17 degrees!!! You’ll stupidly ruin it!) and enjoy the coolness!

... I'll tell you about the outdoor unit later! I would like to inform you that I have been involved in air conditioning and ventilation since 2000 and am ready to help with advice and business in this area!!! So ask away! I’ll answer later, in the evening I’ll answer everyone, because there’s a lot of work right now... I’m running away) Have a good day everyone!

Do-it-yourself split system cleaning

How to properly remove an air conditioner from a wall with your own hands

disassembled indoor unit. How to remove the air conditioning compressor and the outdoor unit itself with your own hands... Remove the protective cover from the housing; ...

Cleaning your air conditioner should not be limited to just caring for the external elements. Dust gets everywhere, accumulates and interferes with the normal operation of mechanisms. You can invite a technician from the service center for maintenance, but many craftsmen cope with this task on their own.

In order to carry out all maintenance work yourself, you need to know the structure of the internal unit of the split system. We will tell you everything about the design of climate control equipment. We will give recommendations according to which it was possible to safely disassemble the unit, clean it and reassemble it again.

Although the design of specific models from different manufacturers varies, the basic diagram by which such climate control equipment is assembled has common basic elements.

The internal block of a modern split system consists of:

• front panel;
• filter elements;
• fan and evaporator;
• engine;
• blinds;
• drainage systems;
• indicator panel, etc.

To properly disassemble the device, you need to carefully disconnect the individual elements in the correct sequence. First, you should carefully study all accompanying documents received when purchasing the device.

Basic structure of the indoor unit: 1- front panel; 2,3 – filters; 4 – fan; 5 – evaporator; 6 – blinds; 7 – panel with indicators; 8 – vertical blinds

In them you can find a lot of useful information on how to disassemble the internal unit of this split system for execution. If for some reason there is no documentation, it makes sense to search for the necessary information on the Internet.

The mesh filter, designed for primary purification of the air entering the indoor unit, must be regularly cleaned of contaminants using detergent

General procedure

First you need to prepare to disassemble the indoor unit: disconnect the device from the network, prepare the necessary tools and materials. You will need various screwdrivers, hexagons, a rag, a container to drain condensation, a stepladder, etc.

Large air flows constantly pass through the indoor unit of the air conditioner, and dust particles remain inside. You need to periodically remove this debris for the device to work correctly.

Different manufacturers use different types of fastenings: bolts, latches, clips, etc. Particular care should be taken when working with plastic fasteners. Excessive force will cause the element to break. Instead of cleaning the device, it will need to be repaired.

First, remove the front panel of the indoor unit. You will have to unscrew the bolts or disconnect the clips; you can carefully pry them off with a straight screwdriver.

After this, the mesh filter and blinds are removed from the housing. Usually these elements, which need to be cleaned quite often, are simply inserted into the housing. Manufacturers provide the possibility of their easy dismantling.

It is important to consider which side the condensate drain tube is connected to. With some Panasonic air conditioners connected to the left, this tube will have to be disconnected to remove the condensate collector

Now you need to find and disconnect the drainage tray, if possible. Sometimes it is built into the body. At this stage, you will need a container for the accumulated liquid, as well as a rag, in case the water spills. In LG air conditioners, such an element is usually attached to one bolt; there are clips located at the bottom; they need to be snapped off.

Then you should remove the impeller shaft. A lot of dust usually accumulates in its grooves. This element is usually removed from the bottom or side. If the design allows, it is preferable to use the first option, it is simpler.

They do it like this:

1. Disconnect the radiator mounts located on the left side of the case.
2. Loosen the impeller fastening screw on the right.
3. Carefully lower the shaft down, holding the loosened bolt with a screwdriver so as not to touch the blades.

All operations must be performed slowly and carefully. The screw that holds the impeller in place is very tight. It must be unscrewed so as not to damage the thread. You don't want to unscrew it all the way because it can be difficult to put it back in exactly the same position.

If it is not possible to remove the shaft from below, you need to use a more complex option:

1. Disconnect the wiring from the control unit.
2. Remove the fasteners and disconnect the unit from the split system.
3. Remove the motor mounts and remove the casing from the shaft.
4. Disconnect the shaft and engine by bending the radiator tubes.
5. Remove the impeller and clean all elements.

When reassembling the device afterward, it is very important to connect all the elements correctly. The blades of rotating parts must not touch the walls of the housing or other components of the device.

Attention will also be required when connecting the wiring. It is better for inexperienced craftsmen to first draw a diagram or photograph the wires so as not to confuse anything while connecting them.

Disassembly using the example of a Panasonic air conditioner

Even such a high-quality device with good filters is not protected from dust getting inside the case. The space between the turbine lamellas turned out to be very small here. Dust accumulates in these narrow gaps, which cannot be removed with a standard vacuum cleaner.

Panasonic has the ability to remove the turbine for cleaning without any problems. Although this is not such a simple procedure as when processing filters. There is no need to remove the housing from the wall; all operations can be performed while standing on a stepladder.

The electronic control unit with indication and other elements of this type are located on the right from the point of view of the master, who stands directly in front of the device. You need to start by disconnecting the case. It has screws on the bottom sides and is held in place with latches on the top.

First you need to unscrew the screws. They are located on the sides and hidden by neat decorative plugs. To find them, the moving part of the body will have to be lifted. Pry off the plugs with a straight screwdriver, then use a Phillips screw to unscrew the fasteners.

In order to disassemble the air conditioner, you need to unscrew the screw, disconnect the condensate collector, then unscrew the screw holding the heat exchanger, then loosen, but do not remove the hidden turbine screw. Finally, you need to lift the heat exchanger and pull out the turbine

Now the case needs to be lifted with a gentle upward movement to disconnect it. There may be a click as it is held in place by three plastic hook latches. Now you can remove another part of the housing, which consists of a cover, a motor and a condensate trap.

This block is attached to grooves located quite deep in the body, but can be easily removed. You need to carefully pull it down with moderate force. If the entire block does not separate at once, you can first release the fastening on the left, and then on the right.

At this stage, you need to pay attention to the position of the hose through which the condensate is discharged. If it interferes (this happens when connected on the left side), then it must first be disconnected from the condensate collector.

The moisture container is not completely separated from the body, since it is additionally connected to it with a pair of thin wires. You need to take care of a stand for this part of the air conditioner in advance or hang it on a cord, rope, etc.

The weight of the condensate collector may cause the wiring to break. As previously mentioned, at this stage accumulated condensate may spill out. It is better to immediately pour the moisture into a suitable container. It's very likely that some of the water will spill, so it's best to keep a rag handy.

You will learn about what should be done if climate control equipment constantly leaks into the room it is treating from, which we strongly recommend reading.

The removed condensate collector will provide access to the technical contents of the unit: on the left, the head of the screw securing the heat exchanger and the rubber bearing of the turbine will become visible. The screw needs to be unscrewed, but the bearing should not be touched; it must remain in the grooves that hold it.

If the split system has not been cleaned for a long time, dust accumulates on its internal elements, and mold also appears, which is dangerous to the health of residents.

Now you need to rotate the turbine with your hands to find the place on its right side where it is secured with a screw on the engine shaft. One lamella is missing here. The screw is recessed deep. It needs to be unscrewed, but should not be removed to facilitate reassembly. After this, lift the heat exchanger with moderate force.

It is secured with latches and you should hear a click. Here you need to act carefully so as not to cut yourself, the edges of some parts are quite sharp. When the heat exchanger comes out of the latches and is lifted, a vertical gap will appear through which you can carefully remove the turbine, after first removing the bearing.

A few words about cleaning

They operate simultaneously: use a brush to treat the available space, and keep the edge of the hose of the turned on vacuum cleaner nearby to immediately remove debris. Some people treat the insides of the unit with dry steam if they have access to a steam generator.

You can then use a cleaning agent, for example in the form of an aerosol. It is kept for some time, you need to act according to the instructions. Then the surface is treated with clean water using a brush or spray bottle to remove the cleaning agent that has dissolved the dirt. You will need a container to collect the draining water.

Now you need to wash the turbine, filters and other elements and dry them. This can be done using common home remedies, but there are convenient kits available for this purpose. Then the device is reassembled. All fasteners must be in place and carefully tightened or latched.

Special products designed for cleaning climate control equipment can effectively dissolve accumulated contaminants. After the allotted time, the composition should be carefully washed off.

Parts removed from the device can be washed with hot water and treated with a brush. There are household chemicals specifically designed for such equipment. But regular laundry soap will give good results. Of course, you need to protect parts from damage.

For example, hard bristles can seriously damage the mesh filter. A lot of dust accumulates on the impeller; every groove needs to be processed. All filter elements are thoroughly washed. They should be dried before installation.

The surface of the evaporator and rotor, as well as the condensate container, are treated especially carefully. It doesn’t hurt to check the condition of the tube through which moisture escapes. If you clean it with a piece of rigid cable, you can find serious dirt there. They are simply pushed out and the tube is washed out.

A special kit for cleaning air conditioners consists of a large plastic bag of a convenient size and a set of devices that give it the desired position

Some craftsmen decided to abandon disassembling the indoor unit. They remove only the front cover and filter, and then cover the wall with polyethylene and rinse the indoor unit with a thin stream of water under high pressure. This is not the best solution, since you can break the air conditioner and damage the decorative finish.

If the cleaning measures did not give the expected result, the full functionality of the split system has not been restored, you will have to. You will find repair instructions in our recommended article.

Conclusions and useful video on the topic

How to disassemble the indoor unit:

To perform such disassembly requires attention, time and patience. The procedure does not require complex instruments or special skills. But inattention during operation is unacceptable, since this can completely ruin the split system.

Would you like to talk about how you cleaned the internal components of the climate control unit with your own hands? Do you have useful information that will be useful to site visitors? Please leave comments in the block below, ask questions, post photos on the topic of the article.

During operation of a household split system, you may feel an unpleasant smell of rot along with air flows from the device. It indicates the need for preventative cleaning of the unit. In addition to the repulsive odor, clogged nodes can cause rapid wear of the power unit, increased energy consumption and allergic reactions in humans.

You can entrust this procedure to a service center employee. But if you have been using a split system for quite some time, you can handle the work yourself, saving money. You just need to familiarize yourself with the disassembly procedure and preventive cleaning.

Indoor unit dimensions

Before installing the indoor unit of the air conditioner, you should inquire about its dimensions. This is especially important during repairs, because modern technologies quite often involve the installation of suspended ceiling systems, which can affect the height of the ceiling, as well as the parameters of the device being described.

On sale you can find non-standard models that have unique sizes. The block length usually varies from 700 to 800 mm. Products up to 900 mm are somewhat less common. Experts recommend taking into account an average length of 770 mm.

As for the height, it is usually 250-290 mm. The average value is 270 mm. The depth is not of much interest to consumers, but it reaches 240 mm. The minimum value is equivalent to 170 mm. From this we can conclude that the average dimensions of the indoor air conditioner unit are 770 x 270 mm.

Knowing these parameters allows you to determine at what distance from the ceiling and walls to hang equipment. There are a lot of contradictions on this issue. Some instructions set the minimum distance to 50mm, while others go as high as 300mm. The optimal value is between 60 and 150 mm.

Experts usually install an air conditioner at a distance of 100 mm. Before installing the indoor air conditioner unit, it is important to consider whether there will be curtains in the room. The step between them and the split system is usually 150 mm. This value can be increased to 250 mm. The average distance from the block to the wall is 400 mm.

Classification of indoor units

In order to disassemble, it is necessary to determine the type of indoor unit of the air conditioner, which can be represented by:

• wall split system;
• duct air conditioner;
• cassette device.

The most common are wall-mounted models, which are more affordable and are sometimes also called household models. Their installation can be carried out in a room for any purpose, and the power within 7 kW allows cooling up to 70 m 2 of area. Such blocks are usually installed at the top of the wall, near the window, since the design provides for the presence of an outdoor unit, and the nodes must be interconnected.

Wall-mounted air conditioners are not capable of supplying fresh air to the premises, since this requires a separate ventilation system. If you are wondering how to disassemble the indoor unit of an air conditioner, you can find this information below. It is for such a device that recommendations are given in the article.

In addition to household air conditioners, some manufacturers supply the market with semi-industrial appliances whose power reaches 10 kW. Outwardly, they resemble traditional split systems, but in terms of parameters they are semi-industrial equipment.

Duct air conditioners are installed with suspended ceilings that hide them completely. Distribution of cooled air is ensured using thermally insulated air ducts, which are located in the inter-ceiling space. Such designs can cool several rooms at once. The power of the equipment reaches 25 kW, which makes it possible to provide cooling for a cottage or several rooms in an apartment. The main feature of duct systems is the ability to supply fresh air in the volume that is guaranteed by the functioning of full ventilation.

Cassette air conditioners require a suspended ceiling during installation. When compared to ducted designs, cassette designs distribute cooled air through the bottom of the unit. It is covered with a decorative grille and usually has the following dimensions: 600 x 600 and 1200 x 600 mm.

Disassembling and cleaning the air conditioner

To clean the indoor unit of the air conditioner, it is necessary to disassemble it. For this purpose, screwdrivers of different configurations and sizes are prepared. Make sure you have a box for collecting fasteners. You will need an electrical and functional diagram of the device. In some models they are applied to the inside of the top cover.

To clean the internal elements you will need:

• clean rags;
• detergent;
• vacuum cleaner.

The first step is to turn off the power to the air conditioner. This complies with electrical safety regulations. The plug must be removed from the socket. The top cover of the unit is removed. The bolts are unscrewed, of which there may be two or three. They are usually closed with decorative plugs. The top cover of the indoor unit is removed. If it is covered with a layer of mold and dirt, it should be washed in the bathroom using detergents and a brush.

When disassembling the indoor unit of the air conditioner, you will need to remove the air filters. They are made of plastic and are designed for rough air purification. Sometimes they are fixed on the lid or inside the air conditioner. The filters are washed under an intense stream of water. A brush will help with this.

The air flow guides should also be removed. The blinds are removed from the grooves. To make the process easier, you need to bend them slightly. These elements direct the flow of cold air into the room and also require intensive washing.

Removing the bottom cover

The next step is to detach the bottom cover. You will need to remove the drain tube and power cord. During this process, you should release the three latches and disconnect the drain pan along with the outlet hose from the block.

Removing Terminal Blocks

The indoor unit of the air conditioner has terminal blocks. They are disconnected during disassembly, and then the electronic control unit and transformer are removed. In order to remove the first one, you need to press out the side fastenings, and then pull the device towards you. Before this, the grounding wires are unscrewed.

Removing the fan motor

Now you can remove the fan motor. To do this, the bolts that are secured to the chassis are unscrewed. The evaporator is lifted and the motor is removed out along with the rotary fan. The motor must be separated from the fan, but first you will have to warm up the bolt head with a soldering iron. This will unlock the thermal lock on the motor pulley. Once the fan blades can be removed, they need to be washed. Assembly is carried out in reverse order.

Cleaning the outdoor unit

External and internal air conditioner units require equal maintenance. The frequency for the first is twice a year, which is true even with intensive use. A vacuum cleaner must be used for this, but the device must be powerful enough to remove dust from external filters and heat exchange radiators.

On your own or with the help of specialists

If the unit is located at an impressive height, then you can unscrew the protective grille and vacuum it, as well as wipe the insides from dust. Otherwise, you can seek the help of professionals who will remove the air conditioner using climbing equipment or a tower. You can clean it yourself using compact senders, but the air conditioning system will have to be de-energized and turned on only 30 minutes after the end of the service.

Finally

During operation of the split system, dust settles on the fan impeller, where a “coat” of dirt forms. This prevents air from flowing through the evaporator. The latter freezes over, and the user does not receive normal cold and intense air flow.

Cleaning the fan of the indoor unit of the air conditioner is also required when you see black flakes flying out of the device. This indicates that the amount of dirt is so large that it is not retained on the internal components. As a preventive measure, from time to time you can dismantle the fan and wash it with chemicals. But not all models allow you to easily remove this part of the system.

For efficient and safe operation of the air conditioner, regular cleaning of the internal elements of the system is required, and in addition to the external one, it is imperative to disassemble and clean the internal unit. Most often, wall-mounted SPLIT devices are installed in offices, apartments and private houses, presented by different manufacturers and modifications. Considering the demand and popularity of climate control equipment, many people will probably be interested in learning how to disassemble the indoor unit of a wall-mounted air conditioner in order to be able to do it themselves.

Design features of the indoor unit

Wall-mounted SPLIT systems from LG and others, including Daikin, Mitsubishi, Toshiba, Fujitsu, Ballu, Samsung and Hitachi, have a similar internal module design. Thanks to this, if you know the basic principles of disassembling an air conditioner, each owner can easily cope with such a task on his own, only for this you should identify the main components and parts that make up such a unit:

Standard design of wall mounted air conditioner

1. Front (front) panel
2. Coarse filter
3. Fine filter
4. Fan
5. Evaporator
6. Horizontal blinds
7. Indicator panel
8. Vertical blinds

You need to understand that proper disassembly consists of following a certain sequence of actions that allow you to gradually get to those elements that need to be cleaned. Only careful dismantling can eliminate the risk of breaking internal components and modules, so you should act carefully, without using excessive physical force. The tools you need are several shaped (phillips) and straight (flat) screwdrivers of different sizes, as well as several hexagonal stars.

Before disassembling, make sure that the air conditioner is turned off from the mains! This is very important to avoid electric shock.

Disassembling the indoor unit of a wall-mounted air conditioner

They begin to disassemble the air conditioner by removing the front plastic panel, which can be attached using clip elements (LG) or bolts (Toshiba), depending on the manufacturer. In the first case, you need to use a straight screwdriver and pry off the clips located at the top and bottom, and in the second, use the appropriate tool. The next step is to remove the mesh filter (coarse cleaning) and plastic blinds from the indoor unit, which are simply removed from the corresponding grooves.

Strainer that needs cleaning

Next, you should carefully dismantle the drainage system of the indoor unit of the air conditioner, which is usually made in the form of a tray. In some models it can be made together with the body and can only be removed with it. Before removing it, you should prepare a container or container in advance to remove condensation. To detach the tray in LG models, you need to unscrew one bolt and snap off the clips located at the bottom.

Drainage tray (on the right side it is disconnected from the blind motor)

Fan/impeller removal options

Next, you need to remove the fan of the indoor unit of the SPLIT system, made in the form of a shaft. This will require very careful and responsible work, since it is important not to damage the internal components and components of the air conditioner.

Removing the strainer

There are two ways to remove the shaft:

1. A simplified version in which there is no need to perform operations with the electric motor and control unit (the shaft is pulled out from below). Usually it is chosen when doing work with your own hands, which requires less time and effort. Here the sequence of operations is as follows:

• Unscrew the bolts/screws and release the radiator on the left side of the main main body of the SPLIT system
• Carefully loosen the fastening on the right, where you will need to carefully unscrew the screw on the shaft itself (as a rule, it is tightened very tightly, so you need to act carefully and slowly so as not to twist the head of the fastening element)

• Carefully remove the shaft component from the housing, from underneath, taking care not to damage the blades (holding the screw with a screwdriver)

Important! When the assembly (installation) sequence is reversed, the fan mounting screw must be in the position where it was originally, since otherwise there is a high risk of the fan blades coming into contact with the walls of the indoor unit.

1. A more complex option is when the shaft is dismantled on the right side, for which the control unit and electric motor are removed. To perform the operation proceed as follows:

• We disconnect the wiring and electronic sensors from the control unit, unclip the fastening clips (in some models we unscrew the fastening screws) and carefully remove the unit
• We unscrew the mounting elements of the electric motor, disconnect the shaft from the casing
• Very carefully and carefully, with slow movements, we disconnect the shaft from the motor, and also bend the radiator tubes

When performing work, it is important to remember all the manipulations in order to assemble everything correctly after servicing the SPLIT unit.

What needs cleaning?

After completing these manipulations, you can begin cleaning the internal components, and here it is imperative to remove dirt deposits from the rotor and evaporator, using antibacterial compounds (active foam), clean water and steam (steam generator tool). The condensate receiving bath is also cleaned of dirt, after which all parts are thoroughly dried. In addition, it would be a good idea to lubricate all moving parts with silicone grease, which will prolong their service life.

To disassemble the indoor unit of the air conditioner, you need to be patient, act carefully and slowly. It is always important to remember that the SPLIT system has a complex structure where all internal components are located very close to each other. This instruction provides a sequence of actions that are performed regardless of the design features of the wall-mounted climate control equipment.

Antibacterial treatment and cleaning of the existing split system must be performed annually. Let’s clarify: we are talking about internal modules used in your home, and office units need to be washed even more often. Maintenance of the external unit is carried out as it gets dirty, but at least once every 2 years. Let's figure out how you can clean your home air conditioner without calling a service technician, that is, with your own hands.

Why servicing more often is beneficial

Unlike old climate control equipment, modern split systems are capable of not only cooling, but also heating the air. Therefore, owners of apartments and private houses often use them until the street temperature drops below -5 °C. Accordingly, the main elements of the air conditioner - filters, heat exchangers and fans - become dirty twice as fast. There are other compelling arguments in favor of timely maintenance:

1. To your health. It is exposed to the harmful effects of fungi and mold that settle and actively multiply inside an overly dusty unit. The sign is an unpleasant musty smell.
2. Dirt accumulated in the external and internal radiator prevents the normal passage of air flow, which reduces the efficiency of the entire installation. With a constant output of heat or cold, more electricity is consumed.
3. Seasonal washing is one thing, but cleaning and antibacterial treatment of a heavily contaminated indoor module is another thing entirely. You will do the first yourself, but for the second you will have to call a specialist with specialized equipment (high pressure washer, steam generator), which will cost you a pretty penny.

Note. A decrease in the efficiency of any refrigeration machine leads to an increase in the load on the compressor - the most expensive part. It turns out that heat exchangers clogged with dirt bring the time of repair, or even replacement, closer.

There is no point in developing the topic of harmful microorganisms living inside dirty air conditioners and harming people’s health, since this fact has long been known to everyone. But it would be useful to find out how much it costs in your region for professional cleaning of split systems with. After all, if the evaporator has not been washed for several years, then calling a specialist becomes inevitable.

Comparative example. The cost of comprehensive cleaning of household air conditioning systems with a power of up to 5 kW is in the range of 2-3 thousand rubles. (35-53 USD). These are Moscow prices; in the regions they may be lower. If you wash the split with your own hands, then you can easily do it in 5, maximum – 10 cu. e., which you will spend to buy the cleaner. Agree, independent prevention is much more profitable than after-sales service.

In the photo - applying Bizol cleaning foam (price - about 6 USD)

Simple foam rinsing

This method of removing dirt from an indoor unit is very simple and accessible to everyone, including housewives. It is performed using detergents sold in aerosol cans (Liqui Moly, Plak, Bizol and the like). The technology is like this:

1. Disconnect the device from the power supply, open the lid and remove the filters. Rinse them with running water and leave to dry.
2. Apply foam from the bottle onto the evaporator fins and wait for the time specified in the instructions (from 10 to 30 minutes).
3. Install the filters and turn on the split system in heating or ventilation mode (depending on the recommendations on the can) and let it work for half an hour. Ventilate the room.

How to foam clean an air conditioner at home is clearly demonstrated in the video:

Unfortunately, this method cannot be called effective, because it only allows you to flush the heat exchanger. The fan turbine, drainage basin and hidden cavities of the device remain dirty. Therefore, next we propose to consider how to properly clean the split system units, having first disassembled them.

How to disassemble and wash the indoor unit

The cleaning process is proposed to be considered using the example of a Korean Daewoo split with a capacity of 18 kBTU or 5.3 kW. What you will need for work:

• flat and Phillips screwdrivers;
• alkaline-based cleaner Carlyclean or similar in a container with a hand sprayer;
• a special polyethylene cover with a water drain, made to fit the dimensions of the indoor module;
• latex gloves;
• another hand-held sprayer to rinse off the cleaner.

For reference. A single dose of Carlyclean can be ordered at any specialized online store at a price of about 3 USD. e. They also sell covers that protect walls from drips (cost is about 2 USD). If you wish, you can solder such a device yourself from plastic film.

Location of fastening screws

To thoroughly clean and disinfect all parts of the internal module, you need to disassemble it in the following order:

Note. Split systems from other manufacturers are disassembled in approximately the same order. Differences occur in the methods of attaching the panels, the number of blinds and the placement of the display.

Cover with drain prevents wallpaper from splashing

If you are servicing your home air conditioner for the first time, the disassembly procedure will take approximately 1.5-2 hours. This gives you access to the fan turbine and the cavity behind it, which also needs to be cleaned. Then everything is simple: pull the cover over the module, sliding its edges between the wall and the body, then start cleaning the “split”:

1. Wear rubber gloves and thoroughly apply cleaning fluid to the heat exchanger, fan drum and internal cavities. At the same time, rotate the turbine with your free hand.
2. After 5-10 minutes, take a water sprayer and wash off the product along with the dirt. You need to spray until clean water runs out of the block.
3. Wait until all the water has drained out of the indoor unit, then remove the cover and let the unit dry.
4. Wash the removed panel, bath and filters and dry them. At the same time, try not to wet the foam seals. After drying, the air conditioner can be assembled.

This is what the turbine and heat exchanger look like after flushing

Advice. It is better to start assembly the next day so that all the parts have time to dry thoroughly. Our video will tell you how to properly disassemble and clean the internal unit of a split system:

Instructions for cleaning the outdoor unit

The main difficulty in servicing the external unit is its location. If it is installed on the wall of a high-rise building on the side of a window opening, then it is better to avoid cleaning it yourself, unless you live on the first floor. It is safer to work when the capacitor is placed in the following places:

• on an unglazed balcony or loggia;
• on the wall of a private house where you can attach a ladder;
• under the apartment window.

The disassembly and cleaning procedure itself is quite simple and is performed in the following sequence:

For reference. The electronics and compressor installed in the external unit are separated from the condenser by a partition, so you can safely apply the product and rinse it off with water.

Washing is carried out from 2 sides - external and internal

It is also better to postpone turning on the cooler for a day so that the seals have time to dry. How to clean the outdoor unit of the air conditioner is shown in the video:

Conclusion

The described self-cleaning technology is suitable for split systems that have not become heavily clogged with dirt. After watching the video, you will see how easy it is to wash the parts of a cooler that has been in use for 1-2 years since the last service. If, upon opening, you find a decent layer of dirt, then it is better to contact a service workshop for the first time. Its specialists will thoroughly clean the air conditioner and perform antibacterial steam treatment, and you will take care of further cleaning.
