Dear guest, stay!

Who should pay for the ventilation cleaning work - me or the homeowners association?

Cleaning the ventilation in the apartment

The apartment is ours cozy corner, where you can hide and relax from the bustle of the city. Is our home safe? Unfortunately not always!

This is what a ventilation duct looks like in one of the apartments in the Moscow region before and after cleaning:

Air flow rate:

• before cleaning - less than 0.3 m.sec.
• after cleaning – 1.5 m.sec.

Bacteria, fungi and microbes are one side of the coin. Another is the lack of normal air exchange in the room.

Cost of cleaning ventilation in an apartment

If there is no impulse (draft) at all in the ventilation duct, this indicates a blockage of the duct. The cost of blockage removal is estimated individually, based on the results of a video examination.

When it's time to clean the ventilation

Note:

• You clean regularly, but the next day you notice thin layer dust on the floor.
• Another day later, clouds of dust and lint formed in some corners.
• The ventilation grille is overgrown with dirty scabs.
• IN summer period in the apartment elevated temperature and stuffiness.

Don’t be lazy, take a piece of paper and bring it to the ventilation grille, it should at least tilt towards it, and at best, be attracted to it. If this doesn't happen, it's time to call a cleaner. ventilation ducts, which, using a special device (Anemometer), will check the presence of draft, speed, temperature and humidity of the air, determine the reasons for the poor performance of the ventilation system and, of course, clean the ventilation in the apartment.

Types of ventilation ducts in apartments

IN various types apartment buildings, exist different kinds ventilation systems with separate channels or central risers. In apartments with separate ventilation shafts, access to the roof of a residential building is required to carry out cleaning work, so before placing an order, please find out from the operating organization the possibility of gaining access.

Ventilation cleaning is carried out using special equipment and a team of qualified smoke and ventilation duct cleaners who have the appropriate certificates.

Many people believe that the operating organizations (housing office, housing department, homeowners association) should clean the ventilation. Yes, this is indeed true, but in practice this does not happen. It’s up to you to clean or not to clean yourself, but know that your health is at stake!

Special offer for housing offices, management companies and homeowners associations - Cleaning of ventilation shafts!

at 12:04 The ventilation system refers to general house systems as well as water pipe risers, electricians to meters, gas pipelines, garbage chutes, elevators and much more. The list of works on these systems is also provided for by the Decree of the State Construction Committee of the Russian Federation dated September 27, 2003 N 170 “On approval of the Rules and Standards technical operation housing stock." If the management company has drawn up a management agreement excluding certain mandatory clauses for the maintenance of the house, it should be changed, those willing to take its place are quickly found today, and if it does not want to do what it should, contact the housing inspectorate, which controls the implementation requirements of the above rules.

Natural ventilation in an apartment building

Organized natural ventilation in a residential building is air exchange that occurs due to the difference in air density inside the building and outside, through specially designed exhaust and supply openings.

For ventilation of premises in a residential apartment building, a natural ventilation system is provided. Let's figure out how it works and how it works.

Natural ventilation device

In each entrance from the first floor to the last there is a common ventilation duct that runs vertically from below, upward with access either to the attic or directly to the roof (depending on the project). Satellite ducts are connected to the main ventilation duct, the beginning of which is usually located in the bathroom, kitchen and toilet.

Through these satellite channels, the “exhaust” air leaves the apartments, enters the common ventilation shaft, passes through it and is discharged into the atmosphere.

It seems that everything is extremely simple and such a mechanism should work flawlessly. But there are many things that can interfere with the normal operation of ventilation.

The most important thing in work natural ventilation the fact that air should flow into the apartment sufficient quantity. According to the projects, according to SNiP, this air must enter through “leaks” window openings, and also by opening the windows.

Excerpt from SNiP 2.08.01-89 (minimum air exchange parameters for an apartment).

But we all understand that modern windows when closed, they do not allow sound or air to pass through.

How to clean and check ventilation in an apartment building

It turns out that you need to keep the windows open all the time, which naturally is not possible for a number of reasons.

Causes of disruption of natural ventilation

• Re-equipment of ventilation ducts

It happens that ventilation stops working due to active neighbors who could simply break the ventilation duct to expand the living space. In this case, the ventilation will stop working for all residents whose apartments are located below.

• Debris in the ventilation duct

It often happens that something gets into the ventilation shaft and simply does not allow the air to move freely. If this happens, then you need to contact the appropriate structure; it is prohibited to climb into the ventilation duct yourself.

• Not correct connection exhaust hoods

Another common problem is connection. kitchen hoods(exhaust hoods) of high power to the satellite channel, which is not intended for this. And when such an exhaust hood is turned on, then a airlock, which disrupts the operation of the entire system.

• Seasonality

Unfortunately, back to work natural system ventilation also has an effect temperature regime, in the cold season it works better, and in the summer, when the temperature outside rises, it works weaker. Added to this are several negative points described above, and the operation of the entire system comes to naught.

And of course, there are mistakes during construction made by the contractor for one reason or another... Only the installation of supply and exhaust ventilation equipment will help here.

Natural ventilation works all year round 24 hours a day. Therefore, a round-the-clock air flow into the room is necessary. If it doesn’t exist, then in winter when closed windows possible condensation, increased humidity up to the formation of mold, to avoid this, install supply valves, this will improve ventilation in the room and get rid of excess moisture.

To organize good air exchange in the apartment all year round. A ventilator will need to be installed. Thanks to this device, you will not have to open the windows, and fresh and clean air will always flow into your apartment.

At the address ________________________, the management organization violates the norms of the Housing Code of the Russian Federation and the Rules for the provision of utility services, namely in the apartment: the ventilation does not work.

In accordance with paragraph 5.5.6 of the Rules and Standards for the Technical Operation of the Housing Stock (approved by Decree of the State Construction Committee of the Russian Federation dated September 27, 2003 N 170), the organization for servicing the housing stock must maintain ventilation ducts and chimneys in technically good condition. At the same time, the calculated temperatures, multiplicities and air exchange rates for various rooms residential buildings must meet established requirements. Natural exhaust ventilation must ensure the removal of the required volume of air from all premises provided for by the project at current outdoor temperatures of 5 C and below. Personnel servicing the ventilation systems of residential buildings are obliged to carry out: routine inspections and elimination of all identified malfunctions of the system; replacement of broken exhaust grilles and their fastening; eliminating leaks in ventilation ducts and shafts; eliminating blockages in channels; troubleshooting dampers and throttle valves in exhaust shafts, umbrellas over shafts and deflectors.

In accordance with paragraph 31 of the Rules for the provision of utility services to owners and users of premises in apartment buildings and residential buildings adopted by Decree of the Government of the Russian Federation of May 6, 2011 N 354, an organization providing utility services to the consumer is obliged to independently or with the involvement of other persons carry out Maintenance intra-house engineering systems, with the use of which utility services are provided to the consumer, as well as recalculate the amount of payment for utility services, including in connection with the provision of utility services poor quality and (or) with interruptions exceeding the permissible duration.

Black mold in the bathroom. IN rented apartment There is a lot of black mold above the bathroom, how can I get rid of it? It is necessary to wash it, clean it with a stiff brush, ventilate it more often so that there is no moisture. Scrape everything off, coat it with a special anti-mold liquid, paint it. Ecofriend tiles/plumbing fixtures, they clean perfectly, you’ll find them on the Internet. Copper sulfate will help, and it’s not mold, but fungus. Wash the walls with a hot solution of baking soda.

Denis Andreychikov
Where can I go to have my bathroom vents cleaned? I contacted the housing department. Cleaned it up and it became so good. Go to the neighbor, if you can’t do it yourself! Housing and communal services are responsible for the maintenance of ventilation ducts; they take money from us for this, that’s all the questions for them. You didn’t write about which home we're talking about. If this is an apartment building, then contact your management company, write a statement, and they will decide for themselves whether to clean the ventilation ducts on their own or submit an application to a specialized organization.

Smell from the sink drain. The reason for the formation and ways to eliminate the unpleasant odor. The corrugation under the sink should be curved so that the water stands there and the smell does not leak out of the drain. Either your drain is done incorrectly (there is no water seal), or the top of the riser is clogged/closed and the water seal is breaking. This happened to us after the cap. renovations in the house when everything metal pipes replaced with plastic ones. I buy Tiret for odor and use it periodically. Moreover, such garbage is only in the kitchen, but in the bathroom everything is fine.

Margarita Ermolaeva
How do you take care of your bathroom? How often do you wash everything in the bathroom? I understand that you are renting an apartment. Then do this. Try not to close the bathroom door for a while so that the dampness disappears. There may be a ventilation problem. Clean the bathtub with Persol, Comit, and then treat it with baking soda slurry... Once a week I thoroughly clean it, and every day I just maintain it. Nowadays there are so many means to maintain cleanliness.

It was as if someone had died in the bathroom. Maybe it's the drain that smells like that? Now it’s autumn, the mice are dying, and it could also be from the ventilation, the same mouse died, or a bird got into the ventilation and also died, although we had such a stink once until it turned out that our Kyrgyz neighbors were drying meat in the kitchen, and everything stank entrance... It all starts from the basement. If the house is multi-story and you are on the lower floors, then most likely the ventilation is coming from the basement

The stench will be terrible! but you will get rid of mold and various kinds insects

Irina Lopatkina
The towels in the bathroom don't dry. What should I do? 1 Clean the ventilation. But this won’t necessarily help; neighbors on the upper floors often drown it out. they have very strong draft.2 Install an electric fan in the air duct so that the air goes there faster. There is no other way out for the heater, otherwise it will go out. Check the ventilation. It definitely needs to be cleaned. There is a coil or for a heater! Indeed, check the ventilation - you need to attach a sheet of paper to the outlet and if the paper is attracted, then there is a draft; if not, call a specialist and have them clean the ventilation. And leave the door open after washing.

There are houses with a common ventilation duct in the bathroom. When such a channel is faulty, odors from neighboring ones begin to enter the apartments. Management organizations must monitor the condition of ventilation ducts and prevent such breakdowns. I was reminded of this again Supreme Court RF.

What is the problem

In relation to the organization managing the house, GZHI conducted an unscheduled inspection of compliance with licensing requirements. During the inspection, it was found that the exhaust ventilation in the bathrooms of several apartments did not work.

As a result, the State Housing Inspectorate drew up reports and issued orders to the management organization to eliminate the violations - to restore the natural exhaust ventilation system in the bathrooms of the apartments. At the same time, a condition was set - to comply with the requirements of clause 4.7 of SanPin 2.1.2.2645-10.

The management organization considered that there was no ventilation in the disputed premises and they wanted to entrust it with the construction of a new one. Construction new ventilation refers to major repair work, and for them a decision is required from the general meeting of owners of premises in the apartment building. Therefore, the management organization went to court to have the orders declared invalid.

Different approaches of the courts to resolving the issue

The court of first instance supported the management organization and recognized the work on restoring the exhaust ventilation system as related to major repair work. The court confirmed that they are carried out by decision of the owners of premises in the apartment building.

The appeal overturned the decision of the trial court, citing

• Licensing Regulations entrepreneurial activity By MKD management, approved by Decree of the Government of the Russian Federation dated October 28, 2014 No. 1110;
• Rules for the maintenance of common property in apartment buildings, approved by Decree of the Government of the Russian Federation of August 13, 2006 No. 491;
• Rules approved by Decree of the State Construction Committee of the Russian Federation dated September 27, 2003 No. 170;

The decision of the appeal court was upheld by the Supreme Court of the Russian Federation. The State Housing Inspectorate’s instructions were recognized as legal, and now the management organization will have to restore the exhaust ventilation system. Why, read on.

Restoring the ventilation system is part of routine repairs

The Appeal and Supreme Court of the Russian Federation refused to satisfy the complaint and ordered the management organization to comply with the instructions for certain reasons.

The UO considered that it would have to make the ventilation system from scratch. In the house itself, the ventilation system in the house was simply out of order. Restoring the functionality of ventilation refers to work on current repairs, there was no talk of a major overhaul.

The management organization must carry out routine repairs, because under the terms of the management agreement concluded between it and the owners of the apartment building, the management organization has assumed obligations for the proper maintenance of the common property.

The courts noted that the management organization is obliged to maintain the common property in the apartment building in proper condition, regardless of whether or not the owners made a decision to carry out certain repair work and whether this is recorded in the text of the management agreement.

Therefore, the courts did not take into account the management organization’s remark that it did not have the owners’ decision to carry out repair work. The case concerned urgent, ongoing work aimed at fulfilling the mandatory requirements to ensure the normatively established level of maintenance of the common property of the apartment building.

Taking into account all of the above, the courts did not satisfy the complaint of the management organization.

Remember

Restoring the functionality of ventilation ducts in a multi-unit apartment building is classified as routine repair work apartment building. Major renovation will be the case if we are talking about building a ventilation duct from scratch.

The obligation to maintain the housing stock in a condition suitable for habitation does not depend on the adoption or non-acceptance by the owners of property in the apartment building of a decision to carry out repair work and fixing them in the text of the contract.

If such a decision is not made, this is not considered an obstacle to the implementation of ongoing work aimed at maintaining the established level of maintenance of the common property of the apartment building. The management organization carries out such work regardless of the decision of the general meeting.

• scheduled inspections and elimination of all identified system faults;
• replacement of broken exhaust grilles and their fastening;
• eliminating leaks in ventilation ducts and shafts;
• eliminating blockages in channels;
• troubleshooting dampers and throttle valves in exhaust shafts, umbrellas over shafts and deflectors.

Who is responsible for the operation of ventilation in an apartment building?

5.7.1. Design temperatures, rates and air exchange rates for various rooms of residential buildings must comply with established requirements. Natural exhaust ventilation should ensure the removal of the required volume of air from all premises provided for by the project at current outdoor temperatures of 5 degrees. From and below….

How to clean ventilation in apartment buildings

Along an even flame that does not deviate towards the decorative grille covering vent, we can conclude that the mine is clogged and needs urgent cleaning. With normal air circulation in houses, the flame leans towards the shaft, and in some cases simply goes out. With this behavior, cleaning the ventilation is not necessary, but if it was last cleaned at least six months ago, it is still advisable to do a little work.

Cleaning ventilation in apartment buildings and in production

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.

Ventilation: what, how, why, when and who

At the dawn of mass housing development, each apartment had an individual ventilation duct, which eventually connected to the exhaust shaft. Over time, when houses became higher and higher, horizontal channels began to be installed between floors, and from them they directed air upward to the ventilation shaft.

Ventilation cleaning: cleaning ventilation ducts in an apartment building

The decrease in ventilation efficiency in old houses is, in principle, a fairly predictable process. The main reason is a simple blockage of the ventilation duct, which over time accumulates debris, dirt, dust and other waste coming from the premises. As a result, the outlet narrows and becomes unable to fully process the dirty air taken in.

Periodic inspection of smoke and ventilation ducts

c) during operation of smoke and ventilation ducts (periodic checks) - at least 3 times a year (no later than 7 calendar days before heating season, in the middle of the heating season and no later than 7 days after the end of the heating season);

Ventilation system maintenance

• conduct service maintenance with strictly approved frequency. You must not violate the terms of technical inspection of equipment and the manufacturer’s recommendations;
• start and stop the operation of the ventilation system in a certain sequence (such measures ensure the complete release of accumulated harmful substances from the air ducts);
• check fan units once a month;
• Check the duct heater for leaks once every 2 weeks;
• control timely oil changes when servicing oil filters;
• check ventilation grids and grilles for blockages once every 3 months;
• monitor the integrity of the sound-absorbing material.

Cleaning the ventilation in the apartment

Ventilation can be called the lungs of a living space. The benefits of an efficiently operating air exchange system are obvious to any person living in an apartment or private house. It directly affects the well-being, health and safety of residents. Regular cleaning of the ventilation in the apartment will ensure a comfortable stay in the house, and will also reduce the possibility of dangerous situations associated with ventilation shafts.

Installation of ventilation and shafts in multi-storey apartment buildings

If an apartment building is not equipped with a ventilation system, all waste products of people remain in the premises. Conditions are created that are dangerous to people’s health and the safety of their property. Mold eats away walls and furniture, and residents suffer from allergies and asthma. Children and the elderly feel the worst in such apartments.

Many residents multi-storey buildings, especially in old buildings, can tell you what culinary preferences their neighbors have, what they treated themselves to for dinner and what they served for lunch. However, we are not talking about telepathy; the neighbor’s menu can be recognized simply by the smell that is felt in the apartment.

If this happens constantly, it means that it is necessary to clean the ventilation, which has ceased to cope with the functions assigned to it. Our recommendations will help restore normal air exchange in the apartment. Minor blockages can be eliminated yourself, but to solve more complex tasks you will have to call specialists.

We will tell you how the ventilation system of a house works, what are the reasons and signs of its malfunction. Here you will learn how to organize the removal of exhaust air and the supply of fresh air. For visual understanding, photo selections, diagrams, and videos are attached to the article.

The air we breathe in the apartment only seems clean. In fact, it absorbs all the odors coming from the kitchen, carbon monoxide from the stove. Dust particles, lint from clothes, carpets, pet hair.

Harmful microorganisms and bacteria accumulate in the air, which contribute to the development of serious diseases; moisture and steam coming from the bathroom cause the formation of fungus and stains. All this negatively affects the microclimate of the room, contributes to the appearance of lung diseases, allergies and other ailments.

If they did not lead to the desired result, and the draft in the channel remained at the same level, then there is a blockage in the common shaft. This is already work special services, which can be called through the Criminal Code.

Licensed companies use professional equipment And special technologies cleanings that are selected after a thorough examination of the canal and taking into account its current condition

Upgrading the system to improve performance

In houses old building mechanical cleaning ventilation shaft even specialized services does not always bring the desired effect. However, it is possible to increase air circulation in the apartment. There are several quite available ways improving ventilation.

If you decide to replace the old ones wooden windows to modern metal-plastic structures, choose double-glazed windows equipped with a micro-ventilation function. If you purchased regular plastic windows, you can install additional devices on them to provide fresh air from the street.

The management company is responsible for the condition of ventilation in an apartment building. In the article we will talk about how the MKD air exchange system is designed and works, and will also focus on Special attention responsibilities of the management company regarding its inspection, cleaning and repair. You will learn what exactly and how often needs to be done to ensure normal operation of communications and the absence of complaints from controllers.

Ventilation in MKD: design, operation and maintenance

By sanitary requirements In the premises of apartment buildings there must be constant air exchange. “Exhaust” air is removed from kitchens, bathrooms and toilets, and fresh air is supplied instead. In the old apartment building, ventilation was carried out through natural exhaust. IN modern houses forced ventilation systems are installed with equipment located in the roofs.

The normal functioning of ventilation in an apartment building is the concern of the organization serving it. Its specialists need to know how this system works, as well as how it is maintained.

Why is there ventilation in an apartment building?

The concept of “ventilation” is disclosed in SNiP 41-01-2003. It refers to the exchange of air flows, in which excess heat and humidity are removed from the premises, as well as unpleasant odors, dust and harmful substances. Well-functioning ventilation ducts in an apartment building help clean the air and create a favorable microclimate in the premises.

The lack of properly functioning air exchange in rooms where people are constantly present not only causes inconvenience, but also poses potential harm to health. Stagnant air in housing provokes development allergic reactions, as well as various respiratory diseases. If the room is not ventilated, it maintains high humidity, which has a detrimental effect on furniture and decorative finishes.

The simplest criterion for assessing how ventilation works in an apartment building is to track the spread of odors from the kitchen. If at open window If they spread throughout the apartment, there are serious problems with air exchange. Residents of upper floors often experience inconvenience due to poorly functioning ventilation, because their apartments lack traction due to the proximity of the end of the duct.

Two ventilation options

The ventilation system in an apartment building can be arranged in different ways - much depends on the layout of the apartments and the building materials used. Air removal can be carried out according to two schemes. Let's describe each of them.

Scheme 1. Leading the ventilation shaft to the attic, where it turns into a horizontal box.

Here, sealed air ducts are combined into a common channel rising above the roof. All air is supplied to a horizontal box, through which it enters a common channel and is discharged outside. The moving air mass collides with the walls of the box, which creates an area high pressure and there is a discharge to the street through the nearest opening.

Scheme 2. Exiting all ventilation ducts to the attic.

Ventilation in an apartment building is arranged in such a way that the attic acts as an intermediate chamber. The ventilation shaft is vented through the roof.

Backdraft in ventilation system MCD does not usually occur. This is due to the short length of the channels (40 centimeters).

A typical apartment building ventilation system works as follows:

• air is removed from the home through ventilation grille and is directed to the adjacent channel;
• satellite channels are connected into a common box;
• air masses enter the collection line through a single air duct;
• protective boxes cover all ventilation shafts in the attic of the apartment building;
• The exhaust air enters the atmosphere through a vertical exhaust duct.

Natural and artificial ventilation

Air exchange systems in apartment buildings are divided into:

• natural, when air enters through holes in the walls and windows;
• artificial (mechanical), when the movement of air masses is forced.

Natural ventilation is good because it is cheap and easy to maintain. The disadvantages include the significant diameter of the ventilation shaft and dependence on weather conditions.

When installing mechanical ventilation in an apartment building, special equipment is used - fans, air conditioners, dust collectors and other devices. Forced ventilation of apartments is much more expensive than natural ventilation. The increase in price is due to higher maintenance costs and the need to pay for electricity. The main advantage of such systems is fast and high-quality ventilation, regardless of external conditions.

Modern systems artificial ventilation can not only remove exhaust air and supply fresh air. They are also capable, for example, of heating and purifying air masses. For natural ventilation additional functions not available.

Features of natural ventilation

Each entrance to the apartment building has its own ventilation duct, which runs through all floors and goes out to the attic or roof. Satellite channels are connected to it, through which air comes from the kitchen, bathroom and toilet. Exhaust air is discharged to the street through a common ventilation duct. The operation scheme seems simple and clear, but in reality there are many factors that can disrupt air exchange.

Ventilation shafts for natural circulation air quality in residential buildings must be mandatory. The requirements for ventilation in an apartment building are as follows:

• sealed design;
• compliance of the throughput with the values ​​specified in the project;
• compliance with sanitary and hygienic standards;
• fire safety system.

According to SNiP, apartments in MKDs are ventilated, including due to slightly open vents or slotted openings in window designs. If the windows constantly remain hermetically sealed, then there will be no normal air exchange in the room. The standards set the speed at which air exchange must occur. We present this information in the form of a table.

Those who service ventilation in an apartment building need to understand why natural air exchange may be disrupted. There are four main points here:

• re-equipment of ventilation ducts. During repairs and redevelopment, residents may violate the integrity of ventilation ducts;
• debris in the path of air movement;
• incorrect connection of fume hoods. Household hoods with high power connected to satellite channels can lead to traffic jams and disrupt the operation of the system;
• seasonal factors. The difference in air temperature in the home and outside affects how the ventilation system will work. In winter, circulation is much better; in the summer heat, on the contrary, it is minimal.

Ventilation operation in the basement of an apartment building

The basement contains an important part of the ventilation system. The shaft, which removes air and supplies it to the apartments, begins precisely at ground floor. From basement It is also necessary to remove stagnant air and humidity, and this is done using a general ventilation shaft. It is connected to each apartment through satellite channels.

Normal basement ventilation in an apartment building prevents the appearance of fungus and mold. Additionally, special vents are provided in the walls, located above ground level. The number of these holes depends on the size of the basement.

Checking the ventilation of an apartment building

A properly functioning ventilation system not only provides comfortable living, but also affects the safety of people. Dry and greasy dust filling the channels is highly flammable and produces choking smoke. In this regard, communications through which Fresh air, need to be checked and cleaned regularly.

By sanitary rules checking ventilation in an apartment building with preventative work carried out at intervals of three months. At least 4 times a year, the management company must inspect communications and, if necessary, bring them to standard condition.

How and when ventilation ducts are checked in residential buildings is determined in Rules 410 (RF RF No. 410 dated May 14, 2013). According to paragraph 12 of this normative document It is necessary to analyze the condition of ventilation ducts and chimneys in the following situations:

• when the house is put into operation for the normal operation of gas or heating equipment;
• if the ventilation ducts were repaired or the apartments underwent redevelopment;
• for prevention. As mentioned above, this is done every three months, a week before the start of the heating season and within a week after its completion;
• when poor traction or its complete absence is detected;
• if there is gas equipment in the house and it was installed, maintained, repaired or diagnosed, as well as if emergency dispatch service was provided.

Ventilation repair and cleaning

The cleaning of ventilation ducts in an apartment building is carried out by specialized organizations that are equipped with necessary equipment. If the necessary equipment is available, the management company can do this. By sanitary standards cleaning must be performed at least twice a year - during the winter and summer seasons.

A preliminary diagnosis is carried out, for which special devices, for example, endoscopes with video cameras. The state of the system is documented. After this, a plan for the necessary cleaning and repair activities is developed.

Most operations to restore the functionality of ventilation systems can be carried out directly on site without dismantling individual elements. If any components require serious repairs, they are removed and transported to the workshop. Specialists organize and supervise these works. management company. They are paid, naturally, from funds collected from residents.

The cost of work is determined by several factors:

• Are there any hatches in the ventilation system for inspection and inspection;
• how dirty the canals are;
• are there any difficulties with access to communications;
• what kind of contaminants are present in the channels.

As a general guide, we provide an approximate price list for services for maintenance and cleaning of ventilation ducts in an apartment building.
