Historians claim that the concept of “ventilation” was first used in Ancient Rome. They did not designate some complex system, A normal ventilation premises. In those distant times Only ventilation of clean rooms was carried out; 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 ducts, 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.
Cleaning process by specialist
- 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.
- 1. In any room of the apartment you need to open the window.
- 2. Apply a flame (candles, lighters) to the ventilation grill in the bathroom or kitchen.
- 3. The deflection of fire into the grille of the exhaust system indicates the serviceability of the system.
- 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.
- 1. Carefully remove the protective grille.
- 2. Before washing the fat, dirt and dust are scraped off the surface.
- 3. The metal frame is immersed in warm water With detergent for more effective removal residual products.
- 4. A vacuum cleaner hose is inserted into the air duct to be cleaned (the unit switches to the “blowing” mode) and the inside of the duct is processed for at least 5 minutes.
- 5. Upon completion of work, wipe the hole with a damp cloth.
- 6. The protective grille is placed back.

A look into the historical past
Few people know that for the first time the inflow and outflow fresh air The ancient Egyptians were able to provide the premises. 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 did the general 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, but in reality 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.
About the need to clean the ventilation in apartment buildings such facts signal:
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
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 and internal reconstruction of 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 testing activities use professional equipment that 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 in the cleaning process ventilation systems, living or working people do not feel any discomfort.
Specialized cleaning equipment
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:
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 fat deposits it is advisable to use dry cleaning, since it is practically impossible to remove such contaminants mechanically (without the use of chemicals).
The quality of air in the apartment depends on the cleanliness of ventilation. Fire safety and the health of people who are constantly in the house, since the lack of fresh air always affects their well-being. The following may indicate household ventilation clogging:
- Visible dirt on the air duct grille.
- Visible dirt on the air ducts behind the grilles.
- Stuffiness in the house, not related to the weather outside the window.
- Insufficient air circulation in the rooms.
- The appearance of mold and the greenhouse effect with high humidity and warmth.
- Long lingering smell of cooking food in the apartment.
According to current legislation, inspection, cleaning and disinfection of ventilation in apartment buildings can only be carried out by specialists. This also applies to ventilation areas located in public areas and ducts inside each apartment. IN own apartment You can clean the grille and duct at arm's length, but if you have ventilation problems, this will hardly help. To return the ventilation in your apartment to a new state and ensure its full functioning, you need to seek professional help.
Cleaning ventilation in an apartment: where to go
If you need ventilation cleaning in your apartment, where to go depends on the situation.
- If you believe that problems with ventilation lie precisely in the ducts inside the apartment, you need to call the SES and call specialists to clean the system at your own expense.
- If you think that the air duct is not functioning properly due to blockages and breakdowns outside the apartment - in the general ventilation system, you need to contact your representative management company home with a request to understand the situation.
If you have never ordered ventilation cleaning in your apartment, it is highly likely that the problem lies precisely in local pollution. You can order air duct cleaning from the Dez Group SES certified by Rospotrebnadzor. By contacting the service, you receive:
- Diagnostics of the entire ventilation system in the apartment.
- Professional cleaning of the ventilation system and its parts.
- Official guarantee for the work performed.
- Your copy of the contract for the service provided, which has legal force.
The ventilation device in the apartment depends on the design of the house and is regulated building codes. Ventilation can be completely autonomous and designed for only 1 apartment or connected to the common air duct of the house. Specialists of SES "Des Group" have everything necessary equipment and skills for high-quality cleaning of both types of systems.
Cleaning ventilation in an apartment: price
You can find approximate prices for home ventilation treatment in the “” section. Exactly how much it will cost you to clean the ventilation in your apartment depends on several conditions; the price of each treatment is always calculated individually.
The cost of cleaning ventilation in an apartment depends on:
- Nature of pollution
- Length of ventilation ducts
- Number of ventilation outlets in the apartment to be cleaned
- Ventilation elements that need cleaning
- Methods for checking ventilation status before and after treatment
- Exit distances for apartments located in buildings outside the Moscow Ring Road
Additional processing discounts may be available if you:
- You order ventilation treatment for several apartments at once.
- You enter into a long-term contract for periodic maintenance and cleaning of ventilation in the apartment.
- Order any sanitary services from the SES in addition to ventilation cleaning, for example, disinfestation or disinfection of the entire apartment.
Residential buildings, institutional buildings, and enterprises have an individual ventilation system to ensure air exchange, consisting of shafts, air ducts and channels. Domestic and industrial ventilation becomes dirty during operation and requires periodic cleaning.
Exhaust ventilation ducts during operation they become contaminated with particles of dust, grease, and chemical fumes household chemicals. Supply ventilation coming into the room from the street becomes clogged even faster.
They get into the air duct
- dust,
- traffic fumes,
- dry leaves,
- insects,
- garbage.
Accumulated dirt settles on the inner surface of the channel, narrowing the ventilation hole. This reduces air exchange, leads to increased load on ventilation equipment and shortens its service life.
If ventilation elements located in cold rooms are not insulated, then condensation appears and accumulates inside. Increased humidity creates favorable environment for the appearance of fungi and mold. In areas with open areas it is convenient to install flexible insulated air ducts.
Air duct contamination is a hazard to human health and safety for the following reasons:
- Deterioration of air quality;
- The appearance of mold, fungi;
- Reproduction of pathogenic microorganisms;
- Increased fire hazard.
Signs of a blockage may include the accumulation of dust and debris on the ventilation grille, rapid dusting of the room after wet cleaning, overheating of the air, lack of drafts when opening doors and frequent fogging of windows.
Regular inspection and removal of contaminants is required. IN Russian Federation such work is regulated by law. Refusal to clean ventilation air ducts, especially in crowded places, risks the spread of infectious diseases that have an airborne transmission mechanism.
Cleaning ventilation in an apartment or house
Vertical ventilation shafts in apartment buildings that belong to common property are cleaned by specialized organizations. The contract for the work is signed by the management company.
You can manually clean the hose up to the shaft yourself; to do this you need to:
- To protect against debris - cover the floor and wall under the ventilation grille;
- Install the stepladder or other stable device;
- Wear personal protective equipment (gloves, respirator);
- Remove the grille, unscrew the fan if present;
- Carefully wash with fat-soluble detergent, wipe dry;
- Use a flashlight to inspect areas of contamination;
- By hand or spatula remove large debris;
- Using a brush or wire brush clear fat deposits, dust from the inner surface of the channel;
- Remaining dirt can be removed using a vacuum cleaner;
- Reinstall the fan and grille.
If plastic air ducts are installed for ventilation, mechanical cleaning must be carried out carefully to avoid damage to the walls.
Professional services use several methods to clean ventilation systems:
- Mechanical using vacuum vacuum cleaners and brush machines;
- Chemical— spraying special chemical solutions in air ducts;
- Cryogenic cleaning dry ice - absolutely safe and effective on any surface.
Professional ventilation cleaning
Modern equipment for cleaning ventilation air ducts allows you to perform cleaning work efficiently and in a short time:
- Brush machine— removes dust deposits mechanically;
- Steam generator, sprayer, compressor - deal with grease stains chemically;
- Core, punch. Used to clean air ducts when they are clogged with construction waste;
- Brushes of different diameters, mounted on a flexible shaft. Manufactured in round, square, rectangular sections;
- Flexible rod— a device for cleaning turning areas. Adapters at the ends of the rod allow you to attach brushes to it;
- Powerful and roomy vacuum cleaner;
- Metal brushes.
Professional cleaning of ventilation air ducts takes place in several stages:
- Diagnostics of the condition of ventilation shafts and chambers is carried out using video inspection systems;
- Removal of rubble;
- Taking samples for the total microbial count in sediment washes and supplied air;
- Cleaning from dust, grease and other contaminants;
- Carrying out disinfection.
After the work has been completed, a commissioning certificate and a periodic inspection plan are drawn up.
Cleaning ventilation from grease in a restaurant
Catering establishments are required to regularly professionally clean their ventilation systems. 
- Huge amount of fat, formed during cooking, and elevated temperatures contribute to rapid contamination.
- Fat, cooling on the inner surface of the channels, forms a layer that is difficult to remove.
- He creates a favorable environment for the proliferation of pathogenic microorganisms and bacteria, which is unacceptable in restaurants.
Cleaning of ventilation air ducts from grease is carried out chemically.
- The alkaline solution is applied to the canal walls using a sprayer and washed off under pressure.
- Thick layers of fat accumulation are cleaned with metal brushes.
At hard work The hot shop must be cleaned once a month. To reduce contamination, grease traps are installed.
According to Federal Law No. 52 of March 30, 1999 “On the sanitary and epidemiological welfare of the population,” sanitary rules must be followed when preparing, storing and selling food and drinks to prevent the occurrence and spread of infectious diseases and mass non-infectious diseases.
Cleaning and disinfection of air duct systems is a sanitary and preventive measure that is mandatory and controlled by state sanitary and epidemiological supervision.
A routine hygiene check should be carried out at least once every 6 months.
After receiving the results of microbiological samples, a decision is made on the need for disinfection.
Cleaning car ventilation ducts
The car ventilation system also needs periodic cleaning. The reason may be the appearance unpleasant odor in car.
Independent work is carried out using special aerosols. To do this you need:
- Free your salon from unnecessary things and objects, aerosol is a chemical agent;
- Remove the cabin air filter;
- Start the engine, turn on the air conditioner in low temperature mode, close the doors for 5 minutes;
- After the time has passed, place a cylinder on the floor near the front passenger seat, turn on the airflow, press the spray button and close the door;
- The aerosol will begin to recirculate along with the air in the vehicle’s ventilation system;
- Open the doors in 15 minutes for ventilation;
- Then turn off the air conditioning, turn off the engine;
- Replace the cabin filter with a new one.
Cleaning car ventilation air ducts yourself is not difficult and economical option. The minimum cost of aerosol cleaners is from 500 rubles.
You can contact the station Maintenance for professional cleaning. This is a reliable option, and also comes with a warranty. The minimum price for services is from 3600 rubles.
Ventilation disinfection
During the cleaning process, contaminant samples are taken for laboratory testing.
If exceeded acceptable values microbiological indicators, carry out disinfection -
- destruction of pathogenic microorganisms,
- bacteria inside ducts and air ducts.
It is performed only after cleaning. This is an important event for maintaining a favorable indoor microclimate and ensuring human health and well-being.
To do this, the cleaned channel surfaces are treated disinfectant solution, permitted by the State Sanitary and Epidemiological Surveillance.
After disinfection, new samples are taken from the canal walls to confirm the effectiveness of the work done.
Dear Managers of production and food enterprises, institutions, management companies and homeowners associations, take measures to ensure our overall sanitary safety - plan, carry out and monitor cleaning and disinfection of ventilation systems.
Ventilation cleaning equipment
Depending on the size and material of ventilation shafts, air ducts, as well as the degree of their contamination, the equipment required in terms of power and configuration is selected.
The technology for cleaning non-flexible and flexible ventilation ducts is different. Review of average prices:
- Set of 5 brushes for mechanical cleaning will cost 9,000 rubles;
- Flexible 6 meter shaft for their attachment - 12,000 rubles;
- Metal brushes from 2,500 rubles;
- Brush machine - RUB 105,000;
- Vacuum cleaner with a flexible shaft - 75,000 rubles;
- A set of steam generator and sprayer with an additional set of tools for cleaning grease - RUB 150,000;
- Video inspection system from RUB 45,000.
How much does cleaning and disinfection cost?
Conduct self-cleaning It is advisable only in relation to property belonging to private property (for example, a sleeve to a common shaft in a city apartment, usually its length does not exceed 0.5 meters).
To do this, it is enough to purchase personal protective equipment, a wire brush and a grease remover.
It is prohibited to clean common house shafts on your own. It is impossible and very dangerous to carry out disinfection yourself.
The cost of specialized services for cleaning and disinfecting air ducts depends on the complexity of the work performed.
The price is influenced by factors such as
- availability of channel locations,
- degree and nature of pollution.
The basic cost of work is usually calculated at 1 square meter air duct, cleaning of ventilation air ducts price:
- Video diagnostics from RUB 5,000;
- Mechanical cleaning of dust deposits from RUB 170;
- Cleaning fatty deposits from 750 rubles;
- Microbiological tests - 1,500 rubles per wash;
- Disinfection from 50 rubles.
Cleaning ventilation air ducts is a necessary mandatory measure, regulated by the legislation of the Russian Federation and aimed at ensuring the health and high efficiency of the population.
Cleaning of ventilation air ducts in Moscow by Dez Group employees.
The sanitary condition of ventilation determines the quality of indoor air and the level of comfort of the environment in which people are constantly located. If the atmosphere is not polluted by harmful impurities and there are no unpleasant odors in the air, this has a beneficial effect on the health of everyone present in the building. Clean and fresh air can have a significant impact on the productivity of office workers, as the lack of oxygen inhibits brain activity. Harmful elements, bacteria and microbes coming from 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 prerequisite for legal business. According to order No. 107 of 08/12/2004:
- A complete inspection of the system must be carried out at least once every 6 months.
- Organize and carry out inspections and cleaning in deadlines tenants and owners of the premises must independently, with the involvement of specialists of the appropriate profile.
- The results of the inspection are recorded in a standard report.
- Based on the data obtained, a decision is made about the need to clean the system.
- The treatment can only be carried out by a full-time ventilation engineer or an invited specialist from a professional sanitary service who has the necessary skills to work with ventilation and hoods.
Ventilation systems must be checked for contamination at least once every 6 months. Sufficient grounds for starting the cleaning process are most often considered to be one of the following factors or a combination of them:
- The presence of visible contamination: 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 tests of air and scrapings from the surface of the system showed the presence of pathogenic microorganisms in it.
The highly specialized SanPiN rules contain separate clauses regulating microclimatic standards for production, work and other premises. They may vary depending on the scope of the company or organization. These requirements have clear quantitative indicators, which are checked with special instruments. When cleaning ventilation air ducts, we must not forget about these indicators. The processing results must bring the system to the standards prescribed by law.
When ventilation air ducts are cleaned, the price is based on technical device, the length of the system and the nature of the pollution. For standard projects this can be a fixed price, for individual ones - the cost is calculated per square meter. You can find out the price for processing your particular system at the stage telephone conversation at the time of contacting the company. When you sign up for a multiple-use service agreement, the price of the service will be lower than when ordering a one-time procedure.
Timely cleaning of air ducts of ventilation systems:
- 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.
- Helps quickly remove foreign odors from the building - burning, food, tobacco, chemicals for processing premises and others.
- Increases the service life of climate control equipment.
- Reduces repair costs and premature replacement of elements or the entire system.
- Saves in all rooms comfortable atmosphere, meeting the requirements of legislation in the field of health and labor protection.
