Ventilation cleaning: cleaning ventilation ducts in an apartment building. Cleaning ventilation in an apartment - how to return clean and fresh air to your home

If residents in their home begin to smell some foreign odors, then it is extremely necessary to clean the ventilation in apartment building. In this article we propose to discuss how ventilation systems located in multi-storey buildings work, as well as how they are checked by special services. Besides, individuals learn how they can clean the ventilation ducts themselves.

Ventilation is a special device that is designed to ventilate various types of rooms. In each apartment located in multi-storey building, has its own ventilation system installed. If an individual suddenly begins to notice different odors, presumably coming from neighboring apartments or the entrance, this means that the ventilation duct has malfunctioned and immediately requires cleaning.

Requirements for the operation of the ventilation system

The state standard number 30494, which came into force in 2011, approved whole line rules regarding work ventilation ducts. Any ventilation system located in a room in which people live must satisfy the following rules:

1. Ensure proper air quality. If a huge amount of harmful impurities is present in the air that a person breathes, then problems with the lungs, as well as other organs, may soon begin. Since the functioning of ventilation ducts is based on the extraction and supply of air, its cleanliness in the apartment must be no less than the minimum limit, the value of which is 1000 CO2. This indicator is measured in cubic centimeters divided by cubic meters.
2. Meet the permissible humidity. Depending on the parameters of the air that comes from the ventilation ducts, the humidity in the room changes slightly. If the air is too dry, the humidity drops significantly. In special situations, this indicator can, on the contrary, reach its maximum value. Ventilation in an apartment building must function so that the minimum humidity level in the room does not reach less than thirty percent, and the maximum does not exceed sixty percent. If the humidity value is in the range from 30% to 60%, then the ventilation system meets the relevant requirements of the state standard.
3. Do not exceed maximum speed air. All ventilation ducts work the same way, however, some of them are newer (located in new buildings), and some are more outdated versions (in houses old building). The length of time an individual has lived in his apartment and how long he has had the ventilation cleaned also plays a huge role. All of the above, as well as additional characteristics, affect the speed of air flow through the ventilation ducts. In accordance with the current state standard, air currents must move no faster than 0.2 meters per second.

Principle of operation

In order for residents apartment buildings could independently monitor the condition of their ventilation ducts and promptly clean them, it is necessary to understand general principles work of this device. In any living space there are several exhaust ducts. As a rule, they are located in the bathroom, toilet, and closets. With their help, polluted air is pulled out of the apartment, and clean air flows in. Thus, the circulation of air masses occurs. However, the question automatically arises regarding where and how it gets into the apartments. fresh air. Everything is very simple. Air masses come from the street through window and door cracks.

It should be noted that in new buildings, ventilation systems operating according to the described principle are practically ineffective. This is due to the fact that almost everything modern houses are built with plastic windows, throughput which air is significantly less than that of wooden windows.

Who checks the condition of ventilation ducts

Apartments are types of property that are personally owned by their owners. In addition, individuals own some other objects under common rights, which include ventilation, roofs, entrances, and so on. For all public facilities of this kind, the management organization is responsible, with which the residents apartment building entered into an agreement to that effect. In this regard, control Current state ventilation ducts, and also take care of them safe work This service is responsible.

Government Russian Federation approved resolution number 410, which displays all the rules according to which the management organization must act when checking the condition of ventilation ducts. Checks can only be carried out by those organizations that specialize in the relevant activities and also have a license to conduct them. also in this document all requirements that must be met when cleaning ventilation are recorded.

Attention! If there are any repairs or construction works, then after they end, the management company must check the condition ventilation system. In addition, the condition of ventilation is checked in cases where residents have received any complaints regarding its operation. If the test results are unsatisfactory, the ventilation must be cleaned.

How to clean the ventilation yourself

In some situations, individuals want to clean the ventilation ducts themselves. Most often, this happens either when the management office delays a visit, the purpose of which should be to clean the ventilation, or when the contamination is insignificant. However, if the ventilation system is covered from the inside with a fairly thick layer of dirt, then it is not recommended to take on the task of bringing it back to normal. If the plaque is small, then in order to clean it, you must follow the instructions:

• Step #1. The first step is to remove the ventilation grilles. Sometimes you have to do this with a screwdriver. After this, the grates need to be thoroughly cleaned of accumulated dirt, rinsed thoroughly under water, wiped, or wait until they dry on their own.

• Step #2. Then you will need to prepare a brush made of metal. The ruff should be as long as possible. If it is not possible to get it, then you can take a metal wire. Then, using a brush or wire, you need to clean the channels that became open to access after removing the grille. The deeper you can get, the more effective the result will be.
• Step #3. And as a final step, clean the channel from dust. You can do this using this household appliance, How regular vacuum cleaner, which will help quickly and easily remove all accumulated dust and dirt.

As long as the ventilation in the apartment is in order, few people think about it. But as soon as a “smell” of dampness appears, there is a reason to check its condition. The health and well-being of all family members directly depends on the quality of the ventilation system, because life is impossible without fresh air. in apartment buildings is not an easy task. But having a little free time and basic skills, you are quite capable of coping with this matter.

Types of ventilation

The ventilation system is installed at the construction stage. Its main purpose is access to oxygen in every room of apartment buildings. The system can be:

• natural;
• artificial.

Natural ventilation Almost all old houses are equipped. Such systems operate due to natural fluctuations in temperature and pressure in the atmosphere. However, in last years This system is gradually being abandoned.

Artificial system ventilation is effective in any weather. She works due to special equipment and provides better air circulation.

Systems are also classified according to the following principle:

• exhaust

Most buildings have both systems installed. The supply air supply ensures the flow of fresh air into the room.

The purpose of the exhaust structure is to remove waste oxygen from the room.

Timely ventilation maintenance is very important. Malfunctions in the operation of the system may not be noticeable at first, but this cannot but affect the well-being of the apartment residents.

Signs of a blockage

It is important to be able to determine when it is needed in an apartment. Clear signs of poor system performance include the following:

• rapid fogging of windows;
• spread of odors from cooking throughout the apartment;
• the appearance of mold and damp smell;
• feeling lack of oxygen;
• accumulation of dust and cobwebs on.

Of course, it is better not to wait until visible signs of blockage appear, but to regularly service the system. Poor ventilation in the apartment leads to damage to repairs, the appearance of fungus and a deterioration of the microclimate in the room.

A way to check the quality of ventilation

To understand whether the hood is working in an apartment, you can perform a simple test. You will need a thin strip of newsprint. It should be brought to the hole.

if the leaf is attracted, then everything is in order with the system

Otherwise, the ventilation in the apartment does not work - the ventilation in the apartment building needs to be repaired. It is important to check every vent in your home. It is advisable to do such checks every month. This will allow you to notice problems in time and fix them.

Why does ventilation fail?

Before you start setting up hoods, it is important to understand why the ventilation in the apartment is not working. There may be several reasons.

1. New plastic windows.
2. Mechanical blockage.
3. Disturbance of balance due to third-party interference in the system.
4. Summer season.
5. Architects' mistakes.

Although in some cases cleaning the ventilation in the apartment can help eliminate the problem, sometimes a person needs the help of professionals. If a disturbance in air exchange occurs after replacing windows, it is important to carefully monitor the frequency of ventilation of the room. While they were installed wooden windows, ventilation was carried out through micro-slits. Plastic structures They close very tightly, so air movement stops. Modern double-glazed windows are equipped with a micro-ventilation function. To restore normal air exchange, it is important to regularly leave the windows in this mode.

In most houses, ventilation shafts are lined with brick. Over time, due to moisture and dust, the material deteriorates and collapse begins. When large fragments get stuck, they block the flow of fresh air. During repairs on top floor Debris may get into the air ducts construction waste, as well as insects and birds. Without the assistance of special services, you cannot clean the entire system yourself. The maximum that is allowed is to restore order in the branch that is adjacent to the common channel.

Often, ventilation repairs in an apartment may be required when one of the neighbors independently connected powerful exhaust system. This upsets the balance that is so necessary for normal air flow in old houses. Resolving this issue can be difficult. Most often it is necessary to install such exhaust systems.

Natural ventilation in an apartment building may cease to perform its functions during the summer heat. When the air temperature outside and indoors equalizes, air movement stops. Therefore in summer time years, you may have to use additional ways ventilation.

The help of a specialist will be required if the quality of ventilation is low due to design errors and construction of the building. In this case, you cannot do without installing special equipment.

Those who have had to deal with low-quality systems often wonder how to improve ventilation in the apartment. Although only special services have the right to carry out large-scale cleaning, using simple methods you can completely improve the quality of the system.

Methods for cleaning ventilation

Before determining how to clean the ventilation in an apartment, it is worth checking it using the methods described above. If it doesn’t work, you should start the process.

External cleansing

Often the need for cleaning ventilation holes noticeable naked eye. Grilles may be covered with a layer of dust, dirt or soot. It happens that the reason for the lack of air draft is precisely this small detail.

Before starting work, it is important to lay down newspaper or polyethylene so as not to stain the floor covering. The ventilation grille is unscrewed using a Phillips screwdriver. The screws must be put in a safe place so as not to be lost.

First, remove all significant dirt from the grate. A metal or plastic scraper is suitable for this. After initial cleaning, the element can be vacuumed. High power will be required for the process to be effective.

Do not use aggressive cleaning agents to clean ventilation grilles. chemical substances. It's better to choose simple remedies which are constantly used in everyday life.

For example, washing or cleaning powder, as well as dishwashing detergent, are suitable.

If the grill is very dirty and difficult to clean, you can leave it in a warm place for a while. soapy water. When the dirt becomes limp, it can be gently rubbed with a brush and rinsed. From detergents The grate should be rinsed under running water.

You can install the element back only after completely dry. However, cleaning ventilation in an apartment building does not end there. There are several other actions that can be carried out without special permission from service providers.

Internal cleaning

When thinking about how to clean the ventilation in an apartment, we must not forget that no large devices or tools should be lowered into the ventilation shafts. Although carrying out large-scale work on your own is prohibited, cleaning the channel leading to the common branch is quite possible.

First, the hole should be carefully inspected. Perhaps there are some fragments of crumbling plaster or brick near the exit. It’s better to remove it all yourself than to let it fall and clog the air duct. If there are no such problems, you can proceed to the next stage.

First of all, the walls of the ventilation shaft are cleaned using a scraper. It is important that no pieces of debris or dirt fall down. The air duct can then be cleaned using a vacuum cleaner.

Although the use of any reagents is prohibited, dry ice can be used. This substance perfectly dissolves dirt and grease. The ice itself gradually evaporates, leaving no traces. It is noteworthy that the use of this product not only facilitates the restoration of ventilation, but also allows you to get rid of unpleasant odors.

You can take a brush or a rigid cable and clean the channel using such tools. It is worth remembering that in ventilation shafts Oh, wasps and other insects often settle in. Therefore, we must not forget about personal safety measures.

How to improve home ventilation

You can install windows with a micro-ventilation system. If double-glazed windows are already installed, they should be improved with the help of special valves for ventilation.

May have to be mounted into the wall supply and exhaust system. She will not only additional means ventilation, but also a way to remove dampness outside.

Cleaning the kitchen hood

It is important to know how to clean properly kitchen ventilation in the apartment on your own. To keep it running smoothly, regular maintenance should be carried out.

The hood is disassembled. You need to remove the cover, grille, filter and air duct. All parts should be washed in warm soapy water. After rinsing, it is important to blot all the elements and let them dry completely.

Assembly can begin after all parts are dry.

After several washes, the filter will have to be replaced. The quality of the hood’s operation depends on its condition. If you notice that there is no ventilation in the kitchen, and odors quickly spread throughout the apartment, then it’s time to clean.

Historians claim that the concept of “ventilation” was first used in Ancient Rome. They did not designate some complex system, but normal room ventilation. In those distant times, only ventilation was carried out clean rooms, for this it was enough to simply open the window. Over the course of several hundred years, the process and equipment have made huge technological leaps.

In the 21st century, many owners of houses and apartments are faced with the acute issue of cleaning air channels, without which effective work ventilation is impossible in principle. Cleaning the ventilation in an apartment or private house should be carried out with the utmost care and regularity. Not only the microclimate of housing, but also the safety of residents depends on this.

Specialist cleaning process

A look into the historical past

Few people know that the ancient Egyptians were the first to provide inflow and outflow of fresh air into a room. In the famous Cheops pyramid, scientists counted more than 300 passages, channels and small tunnels through which oxygen passed. Ventilation cleaning was not carried out in those days, since the system was organized in such a way that it practically did not become clogged.

At the end of the 18th century, the first ventilation wells appeared in houses, thanks to which the microclimate of the living space improved, as well as general state health of the owners. However, the emergence of something new is certainly accompanied by the emergence of related problems. Therefore, it became necessary to regularly clean the ventilation ducts.

At the end of the 18th century, the profession of a chimney sweep was one of the most honorable

The brick wells did not have any protective filters. The surface of the masonry was characterized by pronounced roughness, which helped retain small particles in the form of dust, cobwebs and dead insects. There was a need for a new service for that time - cleaning of ventilation ducts. The chimney sweeps were doing dusty and not very pleasant work. To be fair, it is worth noting that their work was generously paid, and the specialists themselves were held in high esteem.



How to determine when it's time to clean your ventilation system

Most owners of houses and apartments neglect dusty air ducts and completely in vain. For some reason they forget that greasy and dry dust ignites almost instantly, and in the realities of apartment buildings this is fraught with the spread of suffocating smoke and toxic fumes. Cleaning of ventilation ducts should be regular and thorough.

How to determine when it's time to clean your ventilation system

Flow-out channels allow you to effectively remove invisible fungal spores, microbes and allergens from your living space. Gradually they accumulate on the surface of the dust “coat”, and then penetrate into neighboring apartments. A standard grille does not prevent their spread; people actively breathe potentially dangerous air.

The need to clean ventilation in apartment buildings is indicated by the following facts::

• a large amount of fine dust and cobwebs on ventilation grille, around her;
• stuffiness uncharacteristic for the premises in the summer;
• 12-24 hours after wet cleaning accumulations of dust are noticeable on the floor surface;
• feeling of dampness in the room, condensation on the windows.

The main reasons for the above are critical clogging of ventilation ducts and non-working ventilation devices.

Ventilation systems should be checked twice a year

Cleaning the ventilation in an apartment building should be done regularly and much more often than many owners believe. Specific deadlines are set by specialists after analyzing the condition of the air ducts. The recommended frequency of cleaning is 2 times a year (summer and winter), preventive inspection is quarterly.

A story about the operation of ventilation in apartments residential buildings



Checking the functionality of the ventilation duct

You can determine the functionality of the supply and exhaust channels in an apartment with your own hands using improvised means. This information will allow you to determine the state of the system and make a decision on the need to clean the ventilation ducts and replace filters.

A lit match helps in checking the functionality of the ventilation

1. 1. In any room of the apartment you need to open the window.
2. 2. Apply a flame (candles, lighters) to the ventilation grill in the bathroom or kitchen.
3. 3. Deflection of fire into the grate exhaust system indicates the serviceability of the system.

note! It is not worth checking the ventilation in an apartment building yourself using this method, especially if the building is connected to the main gas supply. The slightest gas leak can cause an explosion or fire.

It is much safer to use an A4 sheet of paper or toilet paper. The sequence of actions is maintained, and instead of a flame, thin papyrus is applied to the grate. If the system is cleaned well, then the leaf will be attracted to the surface of the grate.

Check by intelligence agency

In accordance with the Rules, inspection and cleaning of ventilation systems is the specialization of licensed companies. If these are residential buildings, then measures are taken when a lack or deficiency of traction is detected. Inspections are also carried out after repairs, internal reconstructions premises.

And if the frequency of cleaning is 2 times a year, then for scheduled inspections a more stringent framework is established - 3 times a year. Often the period chosen is before, in the middle and after heating season. Specialists conducting inspection activities use professional equipment, which automatically analyzes the performance of the channel.

Cleaning equipment

Cleaning companies that work with air ducts use special equipment to clean ventilation, and they can quickly diagnose the degree of contamination. An important advantage of specialized organizations is that during the cleaning of ventilation systems, people living or working do not feel any discomfort.

Specialized cleaning equipment

• powerful industrial blowers (vacuum cleaners);
• electromechanical units;
• air duct cleaning equipment chemical compounds, reagents;
• pneumatically driven brush installations;
• cleaning devices consisting of several filters;
• vacuum devices.

The choice largely depends on the characteristics of the objects themselves. It can be as large shopping centers, warehouses, restaurants, and ordinary residential buildings.

Also, for self-cleaning small air channels, you can use flexible shafts, which are connected to the source of rotation (screwdriver, drill).

Cleaning methods

In accordance with the law, cleaning of ventilation air ducts must be carried out by specialists from the management company. But the majority neglects the norms and regulations; employees may not appear in the apartments for years. As a result, cleaning ventilation and related responsibilities fall on the shoulders of the residents of the house.

Self-cleaning air channel

Advice! The hatch of the air handling unit is suitable for cleaning, provided that we are talking about small accumulations of dust and dirt. Otherwise, you can’t do without the help of specialists.

So, how to clean the ventilation in an apartment? The sequence of actions is as follows:

1. 1. Carefully remove the protective grille.
2. 2. Before washing the fat, dirt and dust are scraped off the surface.
3. 3. The metal frame is immersed in warm water with detergent for more effective removal residual products.
4. 4. A vacuum cleaner hose is inserted into the air duct to be cleaned (the unit switches to the “blowing” mode) and inner part channel is processed for at least 5 minutes.
5. 5. Upon completion of work, wipe the hole with a damp cloth.
6. 6. The protective grille is placed back.

You can also use the flexible shaft described above.

The difference before and after cleaning the canal

Attention! Self-cleaning of the ventilation system should be carried out without the use of aggressive chemicals or third-party objects that may get stuck inside the structure.

For stagnant fatty deposits, it is advisable to use dry cleaning, since it is practically impossible to remove such contaminants mechanically (without the use of chemicals).

Optimal indoor conditions are created thanks to a properly organized ventilation system. It is important that the amount of air that enters and leaves the room is approximately equal. This will help avoid the formation of drafts. All necessary parameters of the air environment (temperature, humidity and air exchange rate) must be normal so that it is not only pleasant, but also useful to be in such a room. Cleaning the ventilation greatly contributes to this and normalizes the operation of the system.

Reasons for failure of ventilation systems

Even the most productive and efficient system may fail over time. You can determine the deterioration of air circulation if you pay attention to the lack of a sufficient amount of fresh air, also the cause unpleasant odor there may be weak draft in the exhaust air ducts in the room, condensation in rooms with increased level humidity, the formation of fungus and mold. The main reasons that the ventilation system has reduced its functionality are the following factors:

• blockage in the air duct;
• depressurization of a section of the ventilation duct;
• failure of equipment that maintains normal parameters using automatic control.

Most often, system failure is the result of a blockage; in this case, it is necessary to clean the ventilation. To avoid such consequences, it is recommended to perform regular preventive maintenance of the entire system. Measures that even the owner of a private home can take include organizing cleaning of the most difficult areas (elbows, inlets and outlets of ventilation ducts). To do this, it is necessary to take into account the possibility of access to them when designing the system.

Consequences of dirty ventilation

Cleaning the air ducts of ventilation systems will help you avoid a number of problems that usually arise when air stops circulating due to blockage:

• breakdown of equipment, since if the performance of the system has not been reduced, but in one of the areas there are obstacles to the free movement of air, then the device will operate at maximum power values, which threatens overload and breakdown;
• Irregular cleaning of ventilation systems causes deterioration in the well-being of people in the room;
• a decrease in the efficiency of the system, along with its load, leads to a decrease in the service life of all ventilation;
• the accumulation of various contaminants in air ducts, as well as layers of substances on their walls, poses a danger due to the possibility of fire.

Technique used

Special equipment for cleaning ventilation can greatly simplify the task. This saves time and effort, but the owners of private housing do not have specialized equipment, which means that it is necessary to attract professionals to perform such work. Cleaning of industrial and industrial ventilation civil buildings has its own characteristics: the presence harmful substances V air environment, the likelihood of waste elements settling on the walls of the air ducts, the intensity and level of contamination of the air flow passing through the ventilation ducts, etc. It is often necessary to clean the ventilation from grease deposits, for example, this is necessary in establishments Catering or in residential buildings in the hood above the stove.

There are a number of ways to remove contaminants accumulated in ventilation ducts. Here, a lot depends on the configuration of the system in the room, which allows you to use different equipment for cleaning ventilation:

• Brush pneumatic machines.
• Flexible shafts for cleaning ventilation grilles, valves and distributors of various kinds.
• Vacuum type installations.

Self-cleaning ventilation from grease and other complex contaminants will require the use of brushes and detergents. If central ventilation systems are recommended to be serviced for preventive purposes several times a year, then when local ventilation(exhaust hood above the grill, stove) ventilation ducts should be cleaned once a week, otherwise the build-up of fatty deposits can lead to a fire.

Maintenance Features

Technologies allow video inspection of the condition of the air duct. Thanks to these devices, a specialist analyzes the degree of contamination of the system. In order to determine the level of harmfulness of the circulated air due to the content of dust, bacteria and fungal spores in it, an additional chemical analysis. Cleaning the ventilation and air conditioning system also involves disinfection. This is explained by the design features of the air conditioner.

Condensation regularly falls on the surface of the evaporator (one of the main components of cooling technology), which causes constant moisture in the mechanism. Taking into account the fact that air flows of varying degrees of contamination pass through it, some of the dust from the air settles on the evaporator.

As a result, they are created favorable conditions to maintain the vital activity of various bacteria and fungal spores. In this case, the ventilation systems are cleaned and disinfected.

In addition to the use of special equipment, other methods are used to clean ventilation ducts, for example, the use of dry ice. This is the most gentle method, removing almost any contaminant. Dry ice can be used in systems with air ducts made of different materials, besides, after evaporation it does not leave condensation.

Ventilation cleaning in apartment buildings and other large objects is carried out using this method due to its effectiveness. Along with it, other cleaning equipment may be used in certain areas of particular complexity.

Cleaning the ventilation ducts of an apartment in an apartment building is not difficult. The main thing is to know what, how and where to look for the blockage.

The ventilation scheme for residential and utility rooms in a building is a complex and branched system of channels. You can do the cleaning of simple blockages yourself. To break through a large plug you will need special tool and equipment, therefore the work should be entrusted to specialists.

What is the ventilation scheme of an apartment building? You will get the answer to this question by reading the next chapter.

Features of the home ventilation system

The ventilation system is extensive and complex circuit location of ventilation shafts. The design of the ventilation circuit is influenced by many factors. The basis that influences the project being developed is the number of floors in the building.

To furnish the premises apartment building 2 main schemes are used:

• Each room in the apartment has its own channel exhaust ventilation. It goes directly to the roof and ventilation pipe. This scheme has been established before. In multi-storey construction, it is not used. This is influenced by a large area of ​​intra-house cubic space for arranging the ventilation installation.

For this reason, in modern construction conditions, this type of air ventilation system is not installed.

• Ventilation is carried out using exhaust openings from each room, which are connected to a common horizontal box. Here, all air flows are connected and discharged into the attic using a common channel. Air from each hood system, for one entrance, enters a common ventilation duct and is exhausted into the atmosphere.

This scheme began to be used in the Khrushchev era; it is also used in modern construction. This apartment ventilation scheme is considered the most inexpensive and reliable.

The principle of operation of the ventilation system

The installation of the system is carried out in accordance with the requirements of GOST 30494 - 11. According to the standards, the quality level of air masses in the room should not exceed the carbon dioxide level and the humidity of the living room should not exceed 60%, with an air speed of less than 0.2 m/sec.

Previously used natural system ventilation. Special gaps were made above the doors of the rooms for the entry of air masses; wooden windows let in a sufficient amount, even when closed. Vents were installed on the windows to provide clean air.

New buildings, upon installation plastic windows, are equipped with a forced ventilation system. Supply and exhaust circuits with the installation of fans are being installed. These devices allow you to maintain normal levels of humidity and carbon dioxide in your apartment.

But the operating principle of the main ventilation system remains unchanged. The main thing is to carry out routine maintenance on time and remove blockages.

Important. Ventilation checks in apartment buildings should be carried out at least 2 times a year. It is usually carried out in the summer and winter time. But when the first signs of blockages occur, you need to call specialists management company.

Signs of a faulty ventilation system in an apartment

Many residential property owners do not take this problem seriously, considering this situation not hazardous to health. It is in vain to believe that the dust and blockage of a mine or canal will “resolve” on its own and you will not get anything for it. There will be a fire due to greasy dust, which ignites instantly and the gas, when burned, will cause injury to the respiratory system. And even without a fire, no one wants to live in a damp room and breathe stale air.

Important. It is necessary to clean the ventilation ducts efficiently, responsibly, and most importantly – regularly.

The main job of flow-out channels is to remove invisible fungal spores, various allergens and microbes from living spaces. Accumulating on a bed of dust, they, when reverse thrust, penetrate into adjacent premises, people inhale a dangerous air mixture.

The following “symptoms” indicate that the canals are being cleaned:

• a large layer of dust and cobwebs on and next to the ventilation grille;
• stuffy and humid indoor atmosphere in summer;
• After wet cleaning, a layer of dust settles on the floor and furniture within a day;
• Condensation forms on the windows;

If one of the listed items occurs in an apartment, you need to urgently address the critical blockage of the ventilation duct or repair equipment forced ventilation. Checking ventilation in an apartment by a management company includes air quality measurements and an audit of the air duct system. Preventive inspections must be carried out at least once per quarter.

Who should clean the ventilation in an apartment building - there is no clear answer to this question. If the ventilation grille becomes overgrown with dust, you can perform simple repairs yourself. And here serious problems with the system channels can only be fixed by specialists with professional tool and equipment.

Carrying out work by professionals

Using special tools, professionals from a management company or specialized company will quickly and reliably eliminate malfunctions and severe clogging of the ventilation system. Diagnostics is carried out using a video camera, which will show the location of a garbage plug or a section of a destroyed channel.

After the inspection, using a pneumatic brush machine, remove any dirt or debris from the canal. The brush is launched into the air duct. Under the influence of air pressure, it passes through the pipe and destroys the plug. The brush cleans the channel and, at the same time, using a special liquid, disinfects the ventilation air duct system.

By using any open flame source, you can detect the problem without the use of technology. Bring a burning candle or lighter to the ventilation grille. Pay attention to the position of the fire. If the light deviates towards the channel, this means the draft is good and there is no blockage. At vertical position fire - it is necessary to eliminate the malfunction.

DIY air duct cleaning

How to clean the ventilation in an apartment building yourself is very simple. This work involves performing simple techniques:

• remove and clean the ventilation grille, then wash it in a disinfectant;
• If there is a blockage near the channel opening, it can be easily cleaned with a vacuum cleaner or a broom.

Advice! Before carrying out work, remember the safety rules. Be sure to wear safety glasses, gloves and a respirator.

There are situations when the system is working properly, but humidity and dust interfere with normal life. In such cases, you need to think about purchasing and installing supply valves And exhaust fans. These devices will eliminate the nuisance, and installing them is quite easy and simple. The main thing is to know how and where.

In conclusion, some advice from experts.

Old houses and overgrown ventilation ducts do not always allow simple troubleshooting. mechanical cleaning. There are several simple ways to deal with this situation.

When replacing windows, choose metal-plastic products with double-glazed windows equipped with micro-ventilation. If the windows are already installed, they can be equipped with these devices additionally and for not very much money. Plus, you can install them yourself. The simplest ventilation valve will allow fresh air from the street to enter the apartment.

Check the proper functioning of the ventilation at least once every 3 months, and the grille should be cleaned immediately after a small deposit of dust forms on it. Monitor the humidity in the room. If it increases sharply, it is necessary to call specialists to carry out repair work.
