Cleaning ventilation ducts. How to clean the ventilation system yourself? Ventilation systems in an apartment building

The ventilation of clean rooms is invisible to people inside the building. Rarely does anyone think about the operation of the air exchange system while everything is functioning properly. Therefore, ventilation cleaning begins only when the living space is filled with dampness, mold, unpleasant odors, and the windows are covered with "dew".

The well-being of a person directly depends on the surrounding space in general, and access to clean air in particular. The body almost instantly reacts to a lack of oxygen in the room: efficiency decreases, chronic ailments worsen, and high fatigue is observed. All the fault is the clogging of filters and, as a result, a violation of air exchange. Therefore, ventilation must be cleaned

Historical retrospective

Until the end of the 18th century, air ventilation was limited to the banal airing of rooms, rooms or halls. All that was required was to open the door or windows. And no ventilation cleaning required. At a certain stage in the development of society, this state of affairs suited everyone. The owners of the houses turned a blind eye to the dirt and dust that entered the houses without hindrance.

The first wells for air exchange between the internal space and the external environment appeared only at the end of the 18th century, at the same time they began to use primitive equipment for cleaning ventilation. Thanks to the new architectural solution, the quality of life of the then population has improved significantly.

Chimney cleaning was paid well, and chimney sweeps were respected in society

The emergence of something new is certainly accompanied by the emergence of related problems. This rule turned out to be true for the considered system as well. There was a new task - ventilation cleaning. Brick air exchange wells were laid out in the usual way, by analogy with a stove chimney, and therefore, after several months of active operation, the hole was "overgrown" with sedimentary rocks from cobwebs, dust, soot and insects.

Chimney sweeps used metal hedgehogs to remove soot

The development of technologies and an increase in the standard of living of the population contributed to the formation of a new profession for that time - chimney sweep. The frequency of cleaning was high, due to the prevalence of stove heating and fireplaces, and therefore the occupation turned out to be very profitable, albeit dusty.

How to tell when to clean your ventilation system

It is preferable to organize ventilation in an apartment building by means of a forced installation. But in domestic realities, this is the prerogative of housing comfort and premium class. The lion's share of old buildings is equipped with conventional air ducts with a common riser duct. We are talking about the cheapest and simplest connection scheme, but you still need to clean the ventilation ducts, and regularly.

A natural question arises - when to engage in "cleaning" work, by what criteria to determine that the hour "X" has struck?

It is important to determine the degree of contamination before cleaning the air ducts.

A few signs indicating that it is better to hurry up with cleaning ventilation in an apartment building:

  • in the summer season, the rooms turn into a "thermos"; it is not possible to normalize the humidity regime even with regular cleaning;
  • dust actively appears in the living room;
  • the surface of the filters, as well as the grate of the exhaust system, are covered with a layer of viscous soot (typical for kitchens);
  • double-glazed windows constantly "cry", condensation is visible on them;
  • dampness is felt in all rooms, mold and mildew are present on the walls.

Signs of contamination of the ventilation system

For all of the above, often the only reason is a clogged air duct. It is important that ventilation ducts are cleaned at least once every 2 quarters. It is better to delegate the relevant work to specialists; this problem cannot be solved by yourself. The snag may be outside the apartment.

Checking the performance of ventilation ducts

Experts identify several effective ways to determine the quality of the air ducts, the degree of their pollution. The simplest and most reliable is to direct the flame of the lighter into the grill of the hood. Be extremely careful - if the inside of the mine is filled with fine dust and cobwebs, there is a high risk of their ignition, spread and fire.

The flame is sensitive to the presence of draft in the ventilation duct

Cleaning the ventilation in the apartment is not required if the flame goes out or is directed inside the channel. If visually noticeable deviations are not noticeable, immediately contact the management company, in the housing office, for help. The optimal frequency of cleaning is once every 6 months, at least, routine inspections - once a month.

How special services check ventilation

Maintenance of ventilation systems is a responsible event assigned to the management company, due to its belonging to the common property. For this purpose, the Government of the Russian Federation has developed a special Resolution No. 410. In fact, these are a set of rules and regulations for the Criminal Code on cleaning ventilation in apartment buildings, preventive examinations.

The specialist can accurately determine the degree of contamination of the duct

To carry out routine maintenance, a prerequisite is that the company's specialists have a license of the established form. Verification activities are carried out on a quarterly basis, in accordance with the approved plan, during repair and restoration activities, as well as when rebuilding or changing the configuration of channels, lack of traction.

In the arsenal of specialists there are professional devices for checking the functionality of the system, equipment for cleaning ventilation. The channels are periodically disinfected. To remove contamination, pneumatic brushing machines and other devices are used.

Ventilation cleaning: applied equipment

Cleaning the ventilation ducts is a responsible event, which consists of several stages. At the preliminary stage, the specialist determines the degree of contamination of the local air duct, selects the best way to eliminate the problem, if it is detected. Then a decision is made on the expediency of a common channel (coordination of work with other residents of the house).

Equipment for cleaning ventilation systems

Ventilation cleaning is carried out with special equipment:

  • chemical reagents for dissolving stubborn dirt in hard-to-reach places;
  • electromechanical device;
  • vacuum devices;
  • devices equipped with several pneumatic-driven brush mechanisms;
  • powerful industrial vacuum cleaners.

In emergency cases, cleaning the ventilation system ducts can be done by yourself using a flexible shaft with a brush connected to an electric drill.

Not only household processing is in demand, but also industrial cleaning of ventilation and ventilation systems. For such work, highly specialized equipment is used, with the help of which the level of contamination is assessed through a video camera, after which the channel is cleaned and disinfected. During the process, specialists remove all debris, even fatty ones.

Cleaning the ventilation yourself: effective ways

In accordance with the current rules for the operation of housing, apartment owners are prohibited from interfering with the work of engineering and trunk systems. Cleaning the ventilation ducts is the responsibility of the management companies, which can only delegate them to licensed services. But do not forget that "the salvation of the drowning is the work of the drowning themselves."

Self-cleaning of the duct

Each owner should not only know how to clean the ventilation in the apartment, but also be able to do it. The work is simple in its essence, and consists of several steps.

  1. In all rooms where ventilation grilles are installed, they are removed. Accumulated dirt, viscous grease and dust particles are removed. I don't think it's worth focusing on how to wash them with detergent.
  2. The area around the hole is cleaned with a plastic or metal scraper.
  3. To clean the ventilation system, it is better to use a powerful vacuum cleaner by placing the hose in the channel. It is important to "walk" the entire inner area of \u200b\u200bthe hole.
  4. After completing the cleaning measures, the accessible area of \u200b\u200bthe duct is wiped with a damp cloth, the grill is installed in place.

Powerful vacuum cleaner arm with fixed brush

To deal with persistent grease contamination, it is worth contacting a specialized company. Often, their anti-plaque arsenal consists of chemicals that effectively remove residual products that cannot be removed with conventional treatments.

Tools used for cleaning air ducts

For local cleaning of ventilation systems, protective grids, channels in the house, any detergent is suitable. It is better to remove the fatty layer with specialized thick consistencies intended for washing kitchen hoods. In this case, one cannot do without disassembling the air duct, but the cleaning class upon completion of the work will be much higher. Treatment of problem areas with a disinfectant (hydrogen peroxide is quite suitable), will get rid of microbes, spores, "traveling" through the system.

Detergents work well with grease and dirt in the ventilation system

To clean the branched ventilation system, you will have to resort to chemicals and professional equipment. One cannot do without appropriate solutions in private houses, country cottages, where the channels are located under the ceiling cladding. And if household chemicals are quite suitable for cleaning filters, then to solve narrowly focused tasks you will have to buy professional formulations, which is not always profitable.

Duct cleaning cost

Most owners, who receive an exhaustive answer to the question of how to clean the ventilation in an apartment, are wondering how much the corresponding services will cost if they contact a cleaning agency. The price factor depends on the region in which the company is located, the remoteness of the facility, the list of required work.

Below is the price list for the services discussed in this article:

Cleaning ventilation, air ducts will be much cheaper if the company is contacted not by the owner of one apartment, but by a representative from the whole house. In this case, you can count on a significant bonus. If you order regular preventive examinations, having transferred to the status of a regular customer, the total cost of work will be much lower.

Management companies are reluctant to contact the relevant services. It is easier for them to turn a blind eye to the existing problems and to feed the residents "breakfast". Laws, regulations and rules are not written for them, especially when it comes to old houses.

Professional cleaning of ventilation ducts

You should be extremely careful with self-cleaning. In pursuit of perceived savings, it is easy to disrupt the functioning of the system. Don't skimp on your own health and the health of your family.

In any building or structure, a ventilation system must be provided, which is laid during the construction process. The ventilation system is needed to remove polluted and humid air, which is formed as a result of human use of plumbing and household appliances. Also, ventilation is the main element of a favorable indoor climate. Your tone and well-being depends on the air quality.

By the way the air flows move, natural and artificial ventilation are distinguished. It can also be supply and exhaust.

Types of ventilation

Natural ventilation provides for air circulation, which is created due to the temperature difference between the air outside and in the apartment, and atmospheric pressure. These are the cheapest ventilation systems, so almost all old houses are equipped with them. But the system is not widely popular, as it is completely dependent on weather conditions.

Artificial ventilation provides for air circulation, which is created using special equipment. These systems are currently used in all apartment buildings.

Supply ventilation supplies fresh air to the room, and exhaust ventilation removes polluted air using ventilated devices, and today it is the most common system. Therefore, many people have questions such as how to clean the supply and exhaust ventilation. For those who have not experienced this, it will be difficult to follow this procedure, but the following information will help you.

Sooner or later, but any air circulation system clogs up and functions poorly, and the main signs that you need to clean the ventilation in the house are:

  • air blockage;
  • a large amount of condensation on the glass and dampness in the apartment, darkened corners;
  • the formation of a cobweb around the login;
  • large accumulation of dust and small debris.

Reasons for clogged ventilation

The most common cause of air duct clogging is the accumulation of large amounts of dust and dirt in the shafts of these ducts.

The second reason is the failure of ventilation devices.

In all houses, a special service is responsible for the general engineering system, which has access to such work, so it becomes clear who should clean the ventilation in an apartment building. But every tenant has the right to clean the air channel of his apartment. Therefore, it is useful for you to learn how to clean the ventilation in the apartment yourself.

Ventilation cleaning methods

  • cleaning with improvised means. To do this, you need to carefully remove the grate and, using special detergents, remove all grease, dirt and debris from your channel;
  • cleaning with dry ice, which perfectly removes grease and then evaporates without leaving any odor.

Attention! When self-cleaning, do not lower bulky objects into the air duct shafts and use chemical reagents.

If you live in an old building, and you are interested in the question of how to clean the ventilation in Khrushchev, then one mechanical cleaning method will not be enough. To do this, you need to take care of the following things:

  • install a ventilator on new windows, restoring the natural air flow;
  • install a supply and exhaust device that removes moisture from the premises and provides an optimal atmosphere in your apartment. Such devices are mounted both in windows and on walls.

The most likely places for pollution of ventilation in an apartment are a bathroom and a kitchen. Therefore, many people ask themselves how to clean the ventilation in the bathroom. The mechanical cleaning method is suitable for this - 15 minutes and your air channel will be clean.

Ventilation systems in an apartment building

All modern apartment buildings are equipped with two types of ventilation systems:

  1. The vertical ventilation duct is led out into the attic horizontal duct - through this system, air masses from all floors are directed into the horizontal duct and outward.
  2. Vertical air ducts are led out into the attic - through this system, air masses are directed through a single ventilation shaft to the roof.

But these modern ventilation systems do not always cope with their functions. In the first case, air masses from the horizontal box can get into the apartments on the top floor. To avoid this, you must do the following:

  • to double the diameter of the horizontal box, it is better to do this work with a specialist so as not to disturb the engineering structure;
  • lead the air ducts of the last floors into the ventilation shaft above the horizontal duct.

In the second case, in order to improve ventilation, it is sufficient to lengthen the height of the air channel by one meter using a conventional pipe.

How to clean the ventilation

When we know everything about air circulation, we can now learn how to clean this system. This process consists of five steps:

Before starting work, everything must be examined and checked. To do this, bring a lighter or a match with fire to the ventilation outlet. If the flame is drawn into the channel, then there is nothing to worry about, but if it stays still, then your mine is clogged and it's time to find out how to clean the ventilation in the apartment.

Important! If there is a large accumulation of cobwebs, use another non-fire hazardous test method.

Mechanical cleaning

During this you need to take a large ruff or steel cable and clean the air channel, try to clean as much as possible. Clean it of dirt, debris and grease. If this does not help, you need to take larger items and clean again. When cleaning the air ducts, be careful not to run into the nest of wasps or other nasty insects.

Air circulation

To check the natural air circulation, you can use a piece of paper and open the interior doors wide open. If the flap of paper does not react, circulation should be improved. To do this, it is enough to set the gap between the door and the floor at a distance of 4 cm.

Air inflow

Natural ventilation is provided by open windows and doors. But you can't open them especially in winter, so you need to resort to additional methods of air flow into the room. Today, almost every house has plastic windows that securely hold not only heat, but also air. Therefore, all modern windows began to provide supply slots. Cold air comes in from the slots and mixes with warm air from the battery. In winter, this is an effective way to establish an optimal microclimate in an apartment.

True, there are rooms in which the supply slots may not be enough. In this case, supply wall valves are installed, which additionally saturate the room with fresh air.

Additional exhaust system

If, after installing the supply equipment, there is no required air circulation, then an additional exhaust system can be installed. That is, an electric fan is installed in the ventilation duct, which blows air. Thus, it provides your room with a sufficient amount of fresh air.

To finally understand how to clean the ventilation in the apartment yourself, the video will best help you figure it out:

If your special equipment suddenly does not work, then it will not hurt you to know how to clean the crankcase ventilation. Maybe the reason is this. To do this, disconnect the battery and remove the air intake pipe. And then disconnect the throttle actuator and hose. Only then can you start cleaning all other parts.

Optimal indoor conditions are created thanks to a properly organized ventilation system. In this case, it is important that the amount of air that enters and is removed from the room is approximately equal. This will help avoid drafts. All the 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 can fail over time. It is possible to determine the deterioration of the circulation of air flows if you pay attention to the lack of a sufficient amount of fresh air; also, the cause of an unpleasant smell in the room can be weak draft in the exhaust ducts, condensation in rooms with a high level of humidity, the formation of fungus and mold. The main reasons why the ventilation system has decreased its functionality are the following factors:

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

Most often, a breakdown of the system is the result of a blockage, in this case, ventilation must be cleaned. To avoid such consequences, it is recommended to regularly perform preventive maintenance of the entire system. Measures that even the owner of a private home can take are to organize the cleaning of the most difficult areas (knees, entrances and exits of ventilation ducts). For 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 avoid a number of problems that usually arise if the air has stopped circulating due to the formation of a blockage:

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

Applied technique

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

There are a number of ways to remove dirt that has accumulated in the ventilation ducts. Much depends on what configuration the system is in the room, which allows the use of different equipment for cleaning ventilation:

  • Brush pneumatic machines.
  • Flexible shafts for cleaning all kinds of ventilation grilles, valves and manifolds.
  • Installations of the vacuum type.

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

Maintenance features

Technologies allow to make a video inspection of the condition of the duct. Thanks to these devices, the 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 is performed. Cleaning the ventilation and air conditioning system also includes disinfection. This is due to the peculiarities of the air conditioner device.

Condensation regularly forms on the surface of the evaporator (one of the main components of cooling technology), which is the reason for constant moisture in the mechanism. Taking into account the fact that air flows of varying degrees of pollution pass through it, part of the dust from the air settles on the evaporator.

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

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

Cleaning of ventilation in an apartment building and other large objects is carried out using this method due to its effectiveness. Along with it, other cleaning equipment may be involved in certain areas of particular complexity.

Cleaning an apartment from pathogenic microorganisms is an important component of a successful disinfection procedure. However, in some cases, this measure will not be enough. After all, it is not only the internal premises in a building or structure that can be affected by mold and fungus. Cleaning may be required for the duct or the entire ventilation system of an apartment building. Ventilation ducts should be regularly cleaned in commercial facilities as well. Here, this moment is necessarily regulated by law and requires maintaining the appropriate sanitary documents.

It is necessary to clean the ventilation and its maintenance in food production, in places where dirt, dust and grease accumulate. Ventilation equipment and air conditioning systems here can use various methods of regulating gas exchange processes in the room. But the call of specialists, the price of whose work is set based on the complexity and volume of work, allows you to bring it in accordance with the requirements of the SES.

Why do you need to control air exchange?

Features of modern architecture and building engineering imply the arrangement of forced or natural air exchange systems in buildings and structures. If conventional ventilation is not enough to achieve the desired result, supply or supply and exhaust equipment is used to create the desired effect. However, if ventilation systems are not regularly cleaned, even designed according to all the rules, it will work with violations. As a result, instead of clean air, dampness will accumulate in the room, mold and fungal deposits will appear.

Site specialists remind:
Both business representatives and management companies need to regularly carry out procedures associated with maintaining the normal operation of ventilation systems and air ducts. Here, norms and standards are established by the requirements of the SES and make it possible to provide opportunities for the safe life of a person.

Why is ventilation clogged dangerous?

Why is cleaning so important? It is she who allows you to maintain the air exchange system in a safe condition for its operation. It is the serviceability of the ventilation ducts that provides:

  • normal circulation of air flows in the premises;
  • removal of excess moisture and fumes;
  • elimination of pathogenic microorganisms, infections, as well as bacterial microflora;
  • lack of opportunities for their clogging with waste products of rodents or insects.

Regular disinfection of ducts and air ducts provides every opportunity to prevent the possible appearance of rodents, insects, and other pests. If these objects have not been sanitized for years, there is no need to talk about a healthy or comfortable atmosphere in the house as a whole and in its individual apartments. Here we will talk about finding a solution that allows you to quickly and safely eliminate the sources of problems that have arisen.

Existing rules and requirements

The first and most important thing to remember: cleaning of ventilation systems by non-professionals is permissible only as part of removing contaminants on the outer parts of the equipment. It is worth paying attention to the fact that this rule is also relevant for air conditioners. You just need to remember that for any manipulation, more difficult than simple dusting, you should call professionals. As a rule, an integrated approach is used here, which makes it possible to successfully remove not only surface contaminants, but also hazards invisible to the human eye.

The use of special-purpose chemicals by non-professionals should be excluded due to the high risk of poisoning. Their use requires compliance with increased security measures. The equipment with which the work is carried out must be certified and meet the established requirements. Mandatory at this stage is the effectiveness of the system's functioning.

Methods and stages of processing

Professional cleaning of the ventilation system, performed by the specialists of the site, is the basis for the successful and safe operation of air duct systems. We take an integrated approach and produce:

  1. Dry mechanized cleaning, which allows you to create all the conditions for removing dry dust, as well as dirt accumulated since the previous disinfection treatment.
  2. Contact effect on the surface manually - in the presence of stubborn or difficult to remove contaminants, it allows to achieve the desired result and bring the object to the established sanitary regulations.
  3. Compressed air supply to the system, followed by cleaning the damper and automation.
  4. Full-scale disinfection treatment using special technical and mechanical means.

This approach will provide all the opportunities for successful sanitization. Based on the results of the work, an appropriate act of disinfection will be drawn up.

Which organizations require mandatory work?

Cleaning of ventilation systems implies carrying out works related to maintaining the required level of sanitary safety. In office and commercial buildings, in residential infrastructure, as well as in medical and educational institutions, regular processing is regulated by established requirements and standards. In case of violation of sanitary standards, the regulatory authorities impose penalties - in the form of fines, suspension of activities or complete closure of the business. That is why it is necessary to ensure the conclusion of the relevant agreements on behalf of the enterprise, organization or entrepreneur even at the stage of opening your own business.

All business representatives are controlled by Rospotrebnadzor. It is he who determines the processes associated with the conduct of production and industrial activities, and also monitors the observance of the established regulations by service enterprises.

What does the site offer?

The specialists of the site company offer the conclusion of contracts for disinfection, as well as complex cleaning of ventilation ducts and air conditioning systems. A professional approach, modern technical equipment and extensive practical experience allow us to easily cope with the performance of work in any volume. Even the most complex and neglected cases, our specialists allow us to bring them to the established sanitary standards. It is important to understand that when performing work, it is imperative to take into account the type of activity of the company or organization. The frequency of treatments also depends on what the firm is doing.

For owners of their own business, we offer opportunities for the successful and effective implementation of sanitary impact on the interior of ventilation or air conditioning systems. Based on the results of the cleaning performed, our specialists take control measures to assess the efficiency of air exchange and the degree of its intensity.

The quality of indoor air and the level of comfort of the environment in which people are constantly located depends on the sanitary state of ventilation. If the atmosphere is not polluted by harmful impurities and unpleasant odors do not hover in it, this has a beneficial effect on the health of everyone who is present in the building. The cleanliness and freshness of the air can significantly affect the productivity of office workers, as lack of oxygen inhibits brain activity. Harmful elements, bacteria and microbes coming from the ventilation, accumulating in the body, can lead to difficulty breathing, shortness of breath and, with prolonged exposure, to diseases of varying severity.



For organizations, maintaining and cleaning ventilation ducts is a prerequisite for running a legitimate business. According to order No. 107 of 12.08.2004:

  • A complete system inspection must be carried out at least every 6 months.
  • The tenants and the owners of the premises must organize and carry out the inspection and cleaning on time, with the involvement of specialists of the appropriate profile.
  • The results of the check are recorded in the act of the established form.
  • Based on the data obtained, a decision is made on the need to clean the system.
  • Processing can only be carried out by a full-time ventilation engineer or an invited professional sanitary service specialist who has the necessary skills to work with ventilation and extractors.
Due to the specific device, cleaning the ventilation ducts is a process that requires the use of special equipment. The device, which consists of a long shaft with remote control, interchangeable cleaning attachments and a live-view camera, allows ventilation cleaners to follow the process at all stages of the passage through the channels, efficiently clean up dirt and penetrate even into hard-to-reach places that cannot be reached by conventional means. Cleaners, electricians, plumbers or any other employees of the enterprise who are not directly related to air systems should not be allowed to work with ventilation pipes and technical elements of air cleaning and cooling systems.


The ventilation systems must be checked for contamination at least once every 6 months. One of the following factors, or a combination of them, is most often considered a sufficient reason to start the cleaning process:

  • The presence of visible dirt: grease, settled dust, mold, mildew, large debris, etc.
  • The presence of an unpleasant odor in the room, the source of which is the ventilation openings.
  • Laboratory analyzes of air and scrapings from the surface of the system showed the presence of pathogenic microorganisms in it.
The exact frequency of cleaning air ducts of ventilation systems is not spelled out in the law. The rationale for this approach may be the fact that at different sites, climate and ventilation equipment can be contaminated for different reasons, at different rates and with different substances.

In the highly specialized rules of SanPiN, there are separate items that regulate microclimatic standards for production, work and other premises. They may differ depending on the scope of the company or organization. These requirements have clear quantitative indicators that are checked by special devices. When cleaning the ventilation ducts, these indicators must not be forgotten. The results of processing must bring the system to the standards prescribed by law.


When cleaning the ventilation ducts, the price is formed based on the technical device, the length of the system and the nature of the pollution. For typical projects, this can be a fixed price, for individual projects, the cost is calculated per square meter. You can find out the price of processing your system at the stage of a telephone conversation at the time of contacting the company. When signing a contract for multiple services, the price of the service will be lower than when ordering a one-time procedure.

Timely cleaning of ventilation systems air ducts:

  • Prevents the appearance of foreign odors in the room.
  • Reduces the likelihood of pathogenic bacteria, fungi and viruses spreading through the air supply system.
  • Provides the necessary conditions to prevent a disaster in the event of force majeure - fire, smoke, etc.
  • It helps to quickly remove extraneous odors from the building - burning, food, tobacco, chemicals for room treatment and others.
  • Increases the service life of climatic equipment.
  • Reduces the cost of repairs and premature replacement of elements or the entire system.
  • Maintains a comfortable atmosphere in all rooms that meets the requirements of legislation in the field of health and safety.
