Monoblock air conditioners are simply dismantled: the condenser and evaporator are in one block, and freon circulates through pipes inside the housing. This category includes window and mobile air conditioners.
All other air conditioners consist of two or more units, as well as an extended system of pipes and cables. Therefore, the dismantling of such types (and this is a large part modern models) is more difficult and requires the involvement of specialists.
Methods for dismantling the air conditioner
Dismantling an air conditioner with an external unit can be done in two ways: with saving freon in the system and without saving it.
The second option is used if the old air conditioner is not subject to further use, but even in this case, not everything is so simple. Therefore, both for safety reasons and in order not to harm the environment (even if only slightly), it is better to dismantle external unit with preservation of freon. This can be done if you “collect” all the freon in liquid form in the external unit.
Why is it important to keep freon in the system? The point is not in its cost (refueling is often carried out during routine maintenance), but in maintaining the compressor in working condition. If ingested atmospheric air containing dust and moisture, it will fail upon startup.
In order to collect freon in the outdoor unit, carry out the following operations:
- Remove the caps from the fittings of the liquid pipeline (smaller cross-section) and gas. Below them are valves with hex key heads.
- A pressure gauge is attached to the service nipple of the gas fitting.
- Turn on the air conditioner in the “cooling” mode at full power.
- After from indoor unit cold air begins to flow, close the valve of the liquid fitting and monitor the pressure of freon in gaseous form using a pressure gauge.
- After the pressure drops below zero, close the gas fitting valve and immediately turn off the air conditioner. At this time, all the freon is inside the condenser of the external unit.
- After this, it is necessary to “close” the inputs to the capacitor. The simplest and reliable way: cut the copper pipes at a distance of about 15 cm from the fittings (with a pipe cutter, side cutter or metal scissors), bend the ends 180° and clamp them with a small vice (hand or tabletop). You can unscrew the union nuts from the fittings copper pipes, and screw the plugs in their place. But this must be done quickly and carefully so that dust and debris do not get inside the fitting.
All that remains is to disconnect the power and signal cables, unscrew the fasteners, dismantle the external unit and remove mounting structure. Since the external units of most household and semi-professional air conditioners are located on the facade, and they weigh a lot, this should also be done by specialists with safety belts.
Dismantling of indoor units
- remove the housing cover;
- disconnect (cut) the pipeline lines and close them (as with the external unit);
- trimmed drainage pipe;
- disconnect cables;
- open the latches (each trademark own design);
- remove the indoor unit from the mounting plate, and then the plate itself.
Mainly after finishing summer season This is a great opportunity to install new split systems or replace outdated devices with new, more advanced models. Naturally, almost all owners have a question: how to remove the split system yourself and whether this is possible, since calling specialists from this field is very costly. But you can dismantle the systems yourself; you don’t need any special skills. It is enough to know the sequence of work performed.
Oversized split systems
In order to properly remove the split system, you need to know exactly in what sequence you need to dismantle the device. In addition, much will depend on the type of air conditioner. Of course, removing a regular air conditioner is easier than removing and moving a split system to another location, but in any case, if you know the correct sequence of actions, you can handle it on your own.
To begin with, it is advisable to select the tools that will be required for the job. Be sure to take care of this as you will save time by having each key at hand. So, you will need:
- positive and negative screwdrivers;
- hexagons;
- soldering iron;
- wire cutters;
- brush.
The process of dismantling floor or wall air conditioners looks simple.
- First, the channels through which the working fluid circulates are blocked.
- The air conditioner is brought into working position. To ensure that all liquid comes out of the device.
- On last stage the device is disconnected from the network, the drain is disconnected, the pipes that supply working fluid to the device.
- Now the air conditioner can be removed from the wall.
Dismantling split systems
Before you remove the split system yourself, it is important to understand that the most important goal during dismantling is to ensure the safety of freon in the device. It is advisable to carry out the work in such a way that in the future there is no need to refuel the device or completely refill it with refrigerant when the system is installed in a new location.
So, the sequence of actions when dismantling the split system will be as follows.
As you can see, it’s not difficult to remove the split system yourself, the most important thing is correct order work and no rush.
Dismantling of large-sized systems
Cassette-type air conditioners, which are considered the most complex of air conditioning system devices, should be included in a separate group.
These devices are different large sizes and quite heavy, so it is advisable to involve a partner in this process to help. And by the way, keep in mind that during dismantling the system will have to be depressurized. Therefore, after installation in a new location, the pipeline will need to be blown out so that there is no air.
All dismantling work begins with disconnecting and shutting off the pipes through which freon reaches the device. It is also necessary to turn off the electrics and only then turn off the system itself.
For structures of this type, shut-off valves are provided, so work should begin with its disassembly. To do this, it is advisable to use a grinder or hydraulic shears designed for cutting metal.
When the shut-off valves are removed, the device should be removed from the fastenings by pressing them out. If you doubt the correct sequence of work to turn off the electrics, then you can use the manual that comes with all split systems.
Split duct systems
Such devices are the most complex in terms of dismantling work, since they consist not only of fairly massive blocks, but also have a large network of branched air ducts. That is why all work should begin with them. After the air duct system has been disassembled, you can proceed directly to dismantling the device itself.
Work begins from the place where the grille enters the room, then gradually moves to the direct place of their connection, and then is carried out similar works, as with dismantling other systems.
The pipes through which the refrigerant flows to the unit are turned off. Then the device turns on and works until cold air comes out. After this, the device is disconnected from the network and the electrical circuit of the system is completely dismantled.
It should be added that only a few use air conditioning channel type for cooling an apartment or individual residential building, so you are unlikely to have to face the problem of dismantling such a massive and heavy device.
Dismantling the split system in winter
Everyone knows that split systems can be used not only for cooling, but also for heating a room. And the situation sometimes develops in such a way that it is necessary to remove the system in winter. Dismantling devices in winter and summer is somewhat different, since during the hot period it is necessary to pump all the freon into the second unit, which is located outside.
To do this, connect the system to the network, set the “cold” mode, and set the parameters on the pressure gauge low pressure. Next, the flow of coolant is blocked by closing the valve high pressure. As a result of such manipulations, all the freon ends up in the second block, which is installed outside. The split system must be turned off when the pressure gauge readings are zero.
IN winter period Almost all the coolant is in the outdoor unit, so there is no need to pump it. Based on this, it is even easier to remove the split system with your own hands in winter. To do this, simply turn off the device and remove both blocks. The only thing that may be difficult is turning off the taps. If such a problem occurs, it can be easily eliminated by heating them with a hairdryer.
Good to know! Experts do not recommend storing split systems in a disassembled state for a long time. This is explained by the fact that when long-term storage Air can get into the pipes, as a result they will oxidize, and this will cause breakdown of the entire system in the future.
For long-term safe storage, nitrogen must be pumped into the system unit (internal), but this is simply impossible to do on your own at home.
Conclusion
When deciding how to remove the split system yourself, do not forget about your own safety. It’s simple if you live in your own home: set up a stepladder and do necessary work. And if you live in an apartment building, on top floor, and you have neither a loggia nor a balcony?
In this case, without outside help there will be no way around it. You will have to attract friends who could insure you.
Dismantling the split system allows you to clean it. When you disconnect drain hoses, check them out. View the fan blades. It is quite possible that over a period of long operation the surfaces have become dirty, and it would not hurt to wash them.
It is advisable to carry out all work after the equipment has been dismantled and do not forget that the indoor unit has built-in electrical circuits and fees. Therefore, if you decide to wash the fan, be sure to remove it first.
Greetings to all guests and readers of the Air Conditioner website. In this article we will talk about how to remove an air conditioner. It often happens that the internal unit of a split system prevents repairs in the room. In what cases will it be necessary to remove the air conditioner, and is it possible to do without dismantling? We will also consider these questions in the article.
How to “unfasten” the indoor unit of the air conditioner from the wall:
To remove any indoor unit, you must first “snap off” the lower clips. Most blocks have two clips at the bottom, which are indicated by various arrows or serifs. There are three main types of these clips. The first two can be difficult to determine (requires experience or knowledge of a specific model). So, what are their differences:
- hooking onto the plate from above.
In this case, you need to press the clips up to release the internal block;
- hooking onto the plate from below.
Often in such cases there are additional holes (as in the photo). In this situation, the clip must be pulled down from the block. To do this, you will need a device (something like a screw head);
- clips under the decorative cover of the indoor unit.
Here you first need to carefully remove the cover, and then everything becomes clear. Using the LG air conditioner as an example, first unscrew two screws. Afterwards, unhook from the sides front part cover, then pull it all out towards you.
In any case, it is better to contact a specialist, especially if you do not know how the clips of your air conditioner work. Incorrect actions can break the fasteners and the unit will not fit tightly to the wall.
When is it not necessary to remove the air conditioner?
Depending on the scale of the repair and how tightly the indoor unit fits against the wall, there are several options for solving the problem.
1 case. Let's say we plan to re-glue the wallpaper, and the gap between the wall and the block allows us to do this neatly. Then there will be no point in dismantling the block (extra money down the drain). Here you can “snap” the internal unit from the plate and, without disconnecting the communications, hang wallpaper.
Case 2. If plastering and leveling of walls is carried out during repairs, then dismantling of the indoor unit will be required. It is important that, after finishing repair work The length of the communications was enough to install the unit back. During the repair process, you can (grind and putty). Read more about removing only the indoor unit.
Case 3. There are situations when the indoor unit has to be removed along with the route. This may be due to the following reasons:
- if you plan to “lower” the ceiling (the hole through the wall will be lower);
- if the nuts connecting the route to the indoor unit are inside the wall (installation features or errors);
- to prevent the nuts from connecting inside the wall after repairs;
- to move the indoor unit.
In these situations, it is necessary to dismantle the air conditioner. Read the article on how to dismantle a split system.
Reasons for removal components split systems can be different - major renovation in the room, moving to a new home. If you invite a specialist to dismantle the air conditioner, you will have to pay from 2,800 to 4,500 rubles for this service (depending on the model). But this is not the main thing - how long will you have to wait for the master? What if circumstances are such that there is no time? Let's figure out how to do everything ourselves.
The first thing to do is to make sure that the grounding is not broken. Elementary precaution, nothing more.
Removing refrigerant from the indoor unit
- Gas circulates through closed loop. Therefore, the path of its entry to the indoor unit should be blocked. To do this, close the tap on the one outside the window (external). It is located on a suitable copper tube(thin). To tighten it, you need a hex wrench.
- The air conditioner turns on. Mode – cooling.
A number of questions and problems may arise here:
Firstly, the system will immediately fail. Very rarely, but it happens. The solution is simple - connect the external unit directly to the outlet. Naturally, this requires at least basic knowledge of electronic technology. If such reconnection is difficult for the owner, then it is not a sin to turn to a knowledgeable neighbor. There is always a way out.
Secondly, how long does it take to “drive” the system? Nobody will give an exact answer. The operating time depends on the model. By the way, service employees do not like to share this secret, so as not to lose potential clients. But an analysis of all the reviews and advice on this issue allows us to conclude that within 60 seconds (± 2).
During operation of the air conditioner, gas will be removed from the indoor unit and partially from the connecting tube. Naturally, some losses of freon cannot be avoided during further disassembly of the system, but this is already the cost of independent dismantling.
The device is turned off and the tap on the second thicker tube suitable for the outdoor unit is closed, and the first one is additionally tightened (if necessary). That's it - the refrigerant is “driven” and sealed in the condenser.
System de-energized
If the plug is plugged into the socket, it is pulled out. If connected directly to the panel using an extension cable, the circuit breaker is turned off and all ends are disconnected.
Dismantling of communications
Where to start? Whatever is more convenient. The task is to remove all tubes and wires. The main difficulty is disconnecting from the indoor unit. If you need to “squeeze” it away from the wall, there is no need to be afraid - the body is fixed only in the upper part, on a horizontal bar.
On a note! If it is necessary to roll the tubes into a coil, then its permissible minimum diameter– 0.6 m. If twisted more tightly, there is a risk of damage (flattening, breaking) of the walls.
Removing the indoor unit
There are no difficulties in this. Just open the casing cover and it will immediately become clear. As a rule, the block simply lifts up a little and towards itself. By the way, this is a convenient moment to, as well as filters.
Outdoor unit
If all the connections are made, then it is simply removed from the landing “socket”. The difficulty is that it has significant weight. Each model has its own parameter. You may also need help. But how can two people work together? window opening so as not to interfere with each other? All this needs to be thought through.
On a note! The weight of the outdoor unit can be checked from its passport. If it is lost, then there is enough information on the Internet on various systems.
- If the unit is intended to be transported and it is not known when it will be installed again, it is advisable to close all pipes with plugs. For example, twisted pieces of fabric, thick paper. But this must be done to prevent dust from getting into the channels. Otherwise, you will have to call a technician and pay for forced cleaning of the system.
- When disconnecting tubes or wires, their ends must be marked (labeled). Additionally, sketch everything. It is not known when reassembly will take place, so there is no point in relying on your own memory and the fact that the marks will not be erased over time.
- It should be noted that violation of the rules for dismantling the outdoor unit often leads to a refrigerant leak. This means you will need to call a specialist to download it. The work itself is not highly valued (about 650 rubles), but gas is quite expensive. Restoring the functionality of the external unit is comparable to the cost of professional dismantling services. If you are not confident in your abilities, then it is better to contact them immediately.
- Be careful when transporting the air conditioner. The most “delicate” part of the system is Vacuum pump, which is quite expensive. Plus – its installation and adjustment of the system.
And lastly, before disassembling the air conditioning system, you should study the structure of this particular model, the principle of its operation, at least in general terms. Climbing in with a screwdriver and a wrench “blindly” is a guarantee that you will have to send the air conditioner in for repair.
Qualified shutdown and dismantling of the air conditioner requires specialists to have special training and the availability of professional equipment. Services for removing a split system can be quite expensive due to their significant labor intensity. And below you will find out how much it costs to dismantle an air conditioner and about the process itself in more detail.
Modern models of split systems are designed for long-term operation and are characterized by high reliability. Qualified dismantling of an air conditioner involves performing a whole range of complex operations that are associated with carrying out high-altitude work. Attempts to deal with the problem on your own may result in device failure after further installation and connections.
Dismantling household air conditioners and modern split systems are carried out by specialized companies that work in this field. A reputable company should have necessary equipment and well trained staff. We are highly qualified, which ensures the functionality of expensive equipment after its dismantling.
In what cases does it become necessary to dismantle air conditioners?
Split systems are installed by owners of residential premises ( country houses and apartments) and company management in offices. Installation and dismantling of household air conditioners most often occurs with the involvement of qualified specialists. The main reasons for the need to dismantle the device are as follows:
- Moving a person to another place of residence.
- Termination of lease office space with the company leaving the premises.
- The occurrence of significant malfunctions that cannot be eliminated without dismantling the air conditioner with further installation after repair.
- Damage to the internal or external unit of the split system, making its subsequent operation impossible.
- Replacement of a broken air conditioner that has not yet completed its warranty period by representatives of the service center.
In the latter case, the costs of the work can be recovered from the manufacturer of the equipment or its representative office. The manufacturer fulfills warranty obligations if the initial installation and connection of split systems and air conditioners, as well as dismantling for repairs, is carried out by automated companies.
It is important that this is documented, otherwise you will not be able to prove your claims in court. The equipment manufacturer will rely on warranties and refuse to fulfill obligations with good reason.
So, how much does it cost to remove an air conditioner? Average prices
We list the stages of dismantling the air conditioner
Removing an air conditioner involves performing a complex set of works that require experience and high qualifications from the performer. Dismantling, just like installation, must be carried out in in a certain order, by adhering to which you guarantee that the equipment will remain in good condition. It is important to adhere to the following sequence of actions:
- Disconnecting equipment from the network, bleeding the refrigerant from the system.
- Undocking the pipelines and removing the indoor unit of the air conditioner from the wall for further removal of the bracket.
- Preparation for outdoor work and securing components and parts with safety ropes to prevent them from falling.
- Removing the outdoor unit of the air conditioner, console bracket and other installed elements on the external surface of the equipment.
Often, work on dismantling air conditioners involves the need to carry out manipulations on high altitude. Such operations are carried out by industrial climbers with extensive experience.
