There are situations when it is necessary to dismantle the air conditioner. The reasons can be completely different - the old split system does not work, you may be moving, or you are planning to renovate the room. This problem can be solved by calling a specialist from service center. But if you want to save money, have some skills and desire, then you can cope with this task yourself. We will tell you below in our article how to remove the air conditioner from the wall during renovation, while avoiding negative nuances and mistakes, and how to hang wallpaper underneath it.

How to wallpaper under an air conditioner?

This is quite a difficult task. There are people for whom “it will be fine as is,” and there are others who want to do everything perfectly.

There are two ways to hang wallpaper:

• Carefully apply new wallpaper, sliding a couple of centimeters under the device. This method will not bring the desired result, since it will be noticeable to the naked eye that the wallpaper is not completely glued under the air conditioner.
• Remove the air conditioner for a while and stick the wallpaper perfectly.

How to remove an air conditioner from a wall during repairs so that you are pleased with the end result - we will consider in detail below.

Precautionary measures

Before you figure out how to remove the air conditioner from the wall with your own hands, you need to understand how it works in order to avoid unpleasant consequences. This device consists of 2 blocks - external and internal. Two lines connect them, and the refrigerant moves through them. Freon in a liquid state circulates through a tube of smaller diameter from the indoor to the outdoor unit, and it runs in the opposite direction, but in a gaseous state through a thicker copper tube.

This part contains problems that can ruin all your actions when trying to remove the air conditioner with your own hands:

• Complete or partial loss of freon can occur if you disconnect the main pipelines incorrectly.
• Air containing moisture may enter the heat exchanger and tubes, which may cause damage to the air conditioner after it is reconnected. Incompressible moisture enters the compressor and damages the device.
• Entry of small particles into copper pipes pulling them out very quickly leads to system breakdown.
• Handle the threaded fittings that are soldered to the tubes very carefully. If they are damaged, expensive repairs will be required.
• Be sure to mark the terminals so that you can easily reconnect the air conditioner without mixing up the wires.
• Don't cut it too short drainage tube, through which condensate is discharged outside the outdoor unit.

Important! Read the instructions carefully before starting to dismantle the air conditioner so that it does not need to be repaired in the future.

Preparatory stage

It is necessary to prepare a number of tools, without which it is impossible to cope with the task, before answering the question of how to remove the air conditioner from the wall during a DIY repair.

Required tools:

• Pipe cutter
• Gauge manifold.
• Hex socket wrenches.
• Open-end wrenches.
• Side cutters.
• Adjustable wrenches.
• Drill.
• Phillips screwdriver.
• Construction knife.

There are times when you need to acquire safety equipment.

Important! When removing the device, two people must be involved in order to carry out the work without risk to life and health.

Freon release

There are three options for dismantling the air conditioner yourself:

• Disassembly with freon release.
• Preservation of gas inside the device.
• Using a special technique, with the help professional equipment save freon completely.

All methods are used, but the third gives the best effect without any losses.

To remove the air conditioner from the wall with your own hands correctly, you need to study the design of the split system, which consists of a closed circuit filled with freon. It consists of the following components - a compressor, a system of copper tubes and an evaporator with a condenser, which connects the entire system and ensures the selection and supply of refrigerant.

To turn off the air conditioner without losing freon, you need to pump it into the condenser yourself, for this:

1. Close the valve between the device and the thin-diameter tube while the equipment is operating in cooling mode.
2. After a minute, when all the refrigerant has been pumped into the condenser, close the valve on the thick tube. With this action you will turn off the freon supply and “close” it in the trap.

Dismantling with video

To dismantle the external unit, you need to disconnect the copper tubes. To do this, they need to be cut at a distance of about 20 cm from the fitting, and then the sections must be caulked to ensure complete sealing.

Important! Copper tubing cannot be reused because extension is strictly prohibited.

Outdoor unit

Remove thermal insulation after working with copper tubes. It is best when two people work: one outside the room, and the second inside. Removing the device in this way is faster:

• One turns off the power, and the second disconnects the wires, having previously marked the terminals at the place where they are connected.

Important! You have to manually straighten the tubes so that they fit through the holes in the wall without any problems.

• The end of the cable is also screwed to them, which is dragged inside the room.
• Then the nuts are unscrewed, which are held on special brackets outdoor unit.
• Then the two of them remove the block and move it inside the room.

Important! The outdoor unit that you have removed must be stored exclusively vertically.

Indoor unit

How to disassemble indoor unit so that freon does not leak out? Dismantling the internal unit of the device has some nuances, without knowledge of which you will not be able to do all the work correctly, which can lead to breakage of delicate fasteners.

Here's how to remove the indoor air conditioner unit from the wall for wallpapering correctly:

• Remove the housing cover using the indicators located on the bottom of the unit.

Important! Each manufacturer installs the lid differently. Read the instructions carefully to understand how to do it correctly.

• Disconnect electrical cable, to do this, unscrew it from the terminals and carefully pull it out of the system.
• Disconnect the pipe and place a container first, because water may leak out of it.
• Remove the heat insulator and then disconnect the freon pipe. Carefully unscrew the tubes, as you did when removing the outdoor unit, screw them on with caps or wrap them with electrical tape.

Important! You can also cut the tubes, squeeze them and then twist them. The main task is to prevent the entry of polluting components into them.

This household system is dismantled for subsequent repairs or when moving; many users solve the problem simply - call the technicians from the service center. A thrifty owner who has the skills and desire can save money and do everything himself, and we will tell you how to remove the air conditioner correctly, while avoiding mistakes and negative nuances.

Any modern split system, which includes a household air conditioner, consists of blocks for indoor and outdoor locations. They are connected by two lines through which the refrigerant moves. Circulates through a tube of smaller diameter freon in liquid state from the indoor unit to the outdoor unit, the same thing runs through a thicker copper tube in the opposite direction, but in a gaseous state.

This is where problems lie that can ruin everything you do when trying to remove the air conditioner yourself.

1. As a result of improper shutdown of main pipelines, partial or complete loss of freon.
2. Air containing moisture can get into the tubes and heat exchanger, which can cause damage when the air conditioner operates in a new place - incompressible moisture enters the compressor and disables it.
3. If small particles get into copper tubes when they are pulled through a wall or during improper transportation, the system will quickly break down.
4. Particular attention should be paid to the threaded bends soldered to the tubes; if they are damaged, very expensive repairs will be required.
5. Incorrectly disconnected wires. If you do not put special marks on the terminals, it may lead to incorrect connection at the new location.
6. Cutting it too short drainage tube, which discharges condensate outside the outdoor unit, you doom yourself to its premature complete replacement.
7. When transporting a product to a new location, there is a risk of losing small fasteners and parts if they are not securely fastened after disassembly.

All of the above cases lead to very expensive repairs of the entire system, so before you start dismantling the air conditioner yourself, read the instructions.

Preparation

Before dismantling the split system with your own hands, you need to prepare a tool, not a simple one. home arsenal, but purely professional, as shown in the photo:

Many users do not take advice seriously professional craftsmen, how to properly dismantle any split systems. As a result, the shutdown is carried out with numerous violations: they dismantle the product without pumping freon into the air conditioner, and it leaks, which will not be as easy to replenish as many people think.

Refilling the entire system with refrigerant will result in serious financial costs:

• first, the master will check the integrity of all pipelines - 600 rubles;
• refilling an air conditioner with a power of up to 4.5 kW - up to 3 thousand rubles;
• the same actions with equipment power up to 7 kW - up to 3.5 thousand rubles.

At the bare minimum for household air conditioners, this operation will cost you at least 4 thousand rubles, depending on the refrigerant used.

Freon release

There are three ways to dismantle the air conditioner yourself:

• disassembly with freon release;
• keep the gas inside the air conditioner approximately or “by eye”;
• completely save freon with the help of professional equipment using a special technique.

The third option gives the best effect without any losses, but many users use all methods. Experts advise completely preserving the refrigerant so that there are no problems when installing dismantled equipment in a new location.

To properly dismantle the air conditioner, you need to know the design of the split system, which consists of a closed circuit filled with freon. The main components are a compressor, an evaporator with a condenser and a system of copper pipes that connects the entire structure and ensures the supply and removal of refrigerant.

This is what the schematic device looks like modern air conditioner or any split system:

To turn off the air conditioner yourself without losing freon, you need to pump it into the condenser; to do this, when the equipment is operating in cooling mode, you should close the valve between the product and the thin-diameter tube. When all the refrigerant is pumped into the condenser within a minute - that’s exactly how long it will take to completely pump gas into the condenser, you need to shut off thick tube valve, turning off the freon supply, and “close” it in an improvised trap.

Dismantling

Before dismantling the external unit, you must disconnect copper tubes, but in practice they are not reused, since their extension is strictly prohibited. It is necessary to cut them at a distance of about 200 mm from the fitting and caulk the sections for complete sealing.

Attention! When storing the product disassembled for a long time, the tubes are filled with nitrogen and ensure tightness to prevent oxidation of the inner surface.

Outdoor unit

The instructions say: after working with copper tubes, you must remove thermal insulation As a rule, all masters work together, one indoors and the other outside. Thus, dismantling is carried out faster: the partner has turned off the power and now you can disconnect the wires at the place of their connection, first marking the terminals.

The tubes are straightened manually so that they pass through the holes in the wall without interference, and the end of the cable is screwed to them to remove it into the room.

After this, we unscrew the nuts that hold the outdoor unit on special brackets, together with an assistant, carefully remove the unit and move it inside the apartment. Lastly, the brackets are removed from the wall of the building.

Important! During transportation and storage, the dismantled outdoor unit is positioned only vertically to prevent mechanical damage from shaking - it is inserted into a box with foam plastic underneath.

Compressor

Sometimes only the outdoor unit is dismantled, for example, if only the compressor needs to be repaired, and the indoor unit of the air conditioner remains in place. During similar operations, the internal block of the split system is also not touched.

The main condition is to properly dismantle the compressor:

• remove the cover from the outdoor unit;
• then disconnect suction and discharge tubes;
• all electrical wiring is turned off;
• the fasteners of the condenser and fan are unscrewed;
• remove the capacitor from the block housing;
• access to the compressor is open - remove the fastenings and dismantle it.

With such actions, the risk of causing damage to pipelines is eliminated and there is a real opportunity to repair other elements located in the casing of the outdoor unit, if necessary.

Indoor unit

Dismantling the internal unit of an air conditioner has its own very specific nuances, without knowledge of which all your efforts will be useless, and in some cases, careless actions can lead to breakage of rather delicate fasteners, for example, evaporator latches or clamps holding the unit on the guides.

To understand how to remove an air conditioner from a wall, you need to study the instruction manual, which contains the section you are interested in. Many users will not be able to do this operation and will have to turn to professionals.

Remove the indoor unit the air conditioning system will only work after removing the front panel, then you also need to disconnect all the electrical wiring, freon inlet and outlet pipes. You need to disassemble the tangle of wires carefully and without fuss. But this is not all the testing - manufacturers have reliably blocked access to evaporator latches ensure that dismantling is carried out only by specially trained people.

Access is closed by a lid, the latches of which are pressed quite tightly to the wall - you can get to them using two screwdrivers with a very thin tip. Your partner must hold the entire block during this labor-intensive process.

After removing the evaporator, you can unscrew mounting plate , which blocks access to the electrical wires and freon pipes supplying the product, hidden in a special gutter inside the wall. The last thing to unscrew is the decorative box, which runs along outer wall all the way to the outdoor unit.

The disconnected wires are carefully twisted and placed in a separate box for transportation. To help home craftsmen, there is a video on how to dismantle an air conditioner on your own, without turning to specialists:

Dismantling in winter

Many users are interested in the question: how to remove a split system in winter period when due to low temperature it is impossible to pump refrigerant into the condenser. The oil in the compressor will thicken, and all attempts to turn it on can end very badly.

If you have a special model equipped with a kit where there is heating of the compressor crankcase and the entire line drainage system, as well as a block that slows down the rotation of the fan, then your intentions will be crowned with success. If it is not available, you can use a special refrigerant collection station, which is connected in the same way as a pressure manifold.

Several Yet practical advice: You can start dismantling yourself only when you are completely confident in your own capabilities and have a qualified partner. Also availability special tool makes the work much easier.

How to disassemble the air conditioner yourself to eliminate bad smell from a split system? To disassemble a wall-mounted air conditioner with your own hands, you must first become familiar with some of the features of household air conditioners.

How to disassemble an air conditioner

One day, any user of a wall-mounted, household air conditioner is faced with the following unpleasant problem: when the split system is turned on, a stream of cool air, filled with a slightly sweetish smell of already stagnant mold, bursts out of its blowout hole. This means it's time for you to Maintenance your air conditioner, that is, wash it thoroughly, and inside the system. There are two ways to solve this problem: the first is to call the wizard (however this method expensive), the second is independent analysis split system and its subsequent cleaning on your own.

We suggest that you do everything yourself, because this way you will be able to save a certain amount of money, and besides, this skill may come in handy in the future. We present to you detailed guide on disassembling the indoor air conditioner unit, which will help you solve the problem of unpleasant odor from the split system. The considered algorithm for disassembling an air conditioner is typical, so it is suitable for many brands of modern air conditioning devices. So, to disassemble the air conditioner yourself, you will need several negative and positive screwdrivers various diameters, as well as a set of hexagonal sprockets (not for all models of split systems). If you already have such a simple arsenal, then you can start disassembling the indoor unit. Please note that when cleaning the air conditioner, you do not have to remove the device from the wall, disconnect the copper line and drain the freon.

First of all, turn off the power to the air conditioner, and then remove the protective filters from the internal unit of the device. This process is described in detail in the standard maintenance manual for your split system. Next, remove its front panel from the block; to do this, unscrew the two bolts that are covered with protective plugs, then pull the frame towards you (it is held on top by two latches). The inside of the lid will be covered with mold and dust, so immediately send it to the sink. Next, remove the blade that directs the air flow; to do this, apply a little physical force and pull it out of the grooves. Then remove bottom part of the indoor air conditioner unit from the latches, then disconnect the split system drain hose and its power cord.

Next you need to disconnect all the electrical wiring, and it is better to write down how the wires are located. If you are too lazy to write down, and besides, you can boast of your tremendous knowledge in radio engineering, then when you put the air conditioner back together, you can use its electrical circuit, which is located on the inside of the front cover of the indoor unit.

Next, press out the fastening brackets, and then remove the electronic unit housing and the transformer. Then you need to press back the three support latches and carefully remove the drain and outlet hose. The hole for blowing air from the indoor unit, as well as the blades of the built-in fan, will be covered with a strong coating, which emits an unpleasant odor. After this, unscrew the support bolts of the air conditioner motor, carefully lift the radiator, and remove the motor support. Next, remove the blades, as well as the engine from the cell, and you can carefully put the radiator back so that it does not suddenly fall.

Next, remove the thermal lock, which is located on the electric motor pulley mounting bolt. Please note that this is not easy to do. To prevent the rubber element that transmits energy from accidentally burning out, you need to carefully heat the head of the bolt using a thin soldering iron, and periodically try to unscrew it. When you manage to separate the blade from the motor, send all contaminated elements of the system to the wash. To wash all the parts, you will need a bottle of detergent, a brush with fairly long bristles, and plenty of water. Reassembling the air conditioner is carried out in the reverse order.

You can see for yourself that the design of a wall-mounted split system indoor unit is not very complicated. Therefore, in order not to spend extra money, you can clean the device yourself, and besides, you now know how to disassemble the air conditioner yourself.

If you notice that the cold air coming out of the split system has an unpleasant sweetish smell of rot, this means that the unit urgently needs preventive cleaning

In addition to the unpleasant odor, clogging of the internal components of the air conditioner leads to faster wear of the power system of the device, increased energy consumption and, most unpleasantly, can cause whole line allergic respiratory diseases.

Of course, you can have a service technician perform this procedure, especially if the air conditioner is still under warranty. But if you have been using a split system for a long time and do not intend to pay a lot of money for something that you can easily handle on your own, then you should know the procedure for disassembling the air conditioner for its preventative cleaning.

In fact, today there are quite a lot of companies producing split systems, but they all assume a more or less unified system for constructing indoor units. So even if you encounter some design differences, the basic disassembly technique will remain the same.

How to disassemble the indoor unit of a split system for maintenance

First of all, you should prepare a set of screwdrivers of various sizes and configurations work area. Also, do not forget to put boxes next to you for collecting fasteners, as well as a functional and electrical diagram of the air conditioner (in some models electrical diagram applied to inner side top cover of the unit). To clean the internal elements of the split system you will need a vacuum cleaner, detergents and clean rags.

1. Turn off the power to the air conditioner . This is the first thing to do in order to comply with electrical safety rules. Do not turn off the air conditioner using the remote control button, but simply remove the plug from the socket.
2. Remove the top cover of the unit . Unscrew several bolts (two or three) covered with decorative plugs and remove the top cover of the indoor unit of the air conditioner. The lid, which is coated on the inside with a layer of dirt and mold, should be washed in the bathroom using a brush and detergent.
3. Remove the air filters . Remove plastic coarse air filters. They can be mounted both on the block cover and inside it. We also wash the filters under a strong stream of water, helping ourselves with a brush.
4. Remove the guides air flow . Bending slightly, remove the special blinds from the grooves that direct the flow of cold air into the room. They, too, most likely need intensive washing.
5. Disconnect the bottom cover of the indoor unit, drain pipe and power cord of the split system . Carefully press out the three latches, and then disconnect the drain pan along with the outlet hose from the internal block of the split system.
6. Disconnect the wiring terminal blocks, remove the electronic control unit and transformer . To remove the control unit from the split system, carefully press out the side fasteners and then pull the device towards you. Don't forget to unscrew the ground wires before doing this.
7. Remove the fan motor. We unscrew the bolts securing the electric motor to the chassis, lift the evaporator and remove the motor together with the rotary fan.
8. Separate the motor from the fan . First, you will have to carefully heat the head of the bolt with a soldering iron to unlock the thermal lock on the engine pulley. Once the fan blades are removed from the pulley, they can be thoroughly washed in the bathtub.

Assembling the indoor unit of the split system should be done in the reverse order.

Vadim  Unscrew two or three screws under the horizontal blind.

Then carefully move the bottom of the body aside. Try to ensure that the blinds fit through the slot. There are three hooks on the top that will unhook themselves. After removing the case, carefully remove the thermal resistor from the slot.
Then, on the left side, unscrew one screw holding the drainage tray, carefully slide it off the hooks and let it hang on the drainage hose.
The fan will be freely accessible.
Be careful when assembling. Don't break the hooks.

Service maintenance of 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 in this moment(I hope the moderators will be understanding)! The fact is that consumers are often misled by offering them service maintenance air conditioning every year!!! 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 let's remove it completely top part housing, together with the lid...

We unfasten the bathtub (through it the condensate gets out into the street)...

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

So we got to the main point that I wanted to tell you about! WITHOUT DISASSEMBLYING THE AIR CONDITIONER, you can see the degree of contamination and draw your own conclusion... is it necessary to clean it?
Please note... The fan impeller we need to clean!!!

We remove the impeller (if possible), wash it with a stream of water and a brush, and clean the radiator using a steam generator... VOILA:

Then we proceed to assembling the indoor unit, in reverse order! But those same mesh filters...

Fasten the lid, put the meshes...

Close the lid of the indoor unit...

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!
