Cost duct cleaning: How Much Does Air Duct Cleaning Cost? A Budgeting Guide (2022)

Is Air Duct Cleaning Worth The Money?

The summers can be real scorchers where I live in North Bergen, New Jersey. As a matter of fact, in the next three days our township will be averaging around 95° Fahrenheit. That’s pretty hot for Northern New Jersey. All I can say is that I am happy I was able to get my HVAC unit replaced before this upcoming heatwave. 

It was just last week when I came home from a socially distancing engagement party and felt warm air against my face while hearing the air handler running. I went to the nearest floor vent and felt warm air blowing. At that point, I shut down my cooling system and reached out to my local HVAC guy. I told him that it was time to replace my air conditioner and I needed it done before the weekend. After laying out $4,000, he ordered a new furnace, condenser, and air handler. The team managed to get the system installed half way, in order to cool the home. I am still waiting for them to complete the job.

While they were busy hooking up the new system, the lead installation expert mentioned to me that my air ducts happened to be rather dirty. I told him that I heard about air duct cleaning but was unsure if it was really worth it. He didn’t really give me a clear answer so I decided to do the homework myself and lay out both sides of the air duct cleaning debate.  

To Clean or Not To Clean Your Air Duct? That Is The Question

After doing a substantial amount of research I found that professional HVAC installers will be hesitant to clean the air ducts while local air duct cleaners will naturally recommend having them cleaned.  Each has their own opinion, but what is most important for a homeowner is to ask yourself the following question “Why do I want my ducts cleaned?”. With the following information below you will be better able to answer that question and decide if air duct cleaning is really worth it.

HVAC Installers Take On Air Duct Cleaning

The way an air conditioning system works is complex but can be explained in a three step process. First, the air flow will begin at the supply register which passes through a filter. Second, the air will pass through the ac coils and is cooled down and conditioned. Third, the cool air will then pass through the air handler and be pushed into your ducts. At this point, the cool air will be distributed throughout the house until the desired temperature is achieved. 

Assuming that you change your filter often, a good filter should prevent most dust and particles from entering into your ducts. Any remaining particles which do enter the duct work will begin to slowly build up over the course of time. After ten or fifteen years, there might be a nice film of dust lining both metal and flex ducts. HVAC installers are not afraid of this dust loosening and getting blown into the living area of the home as the dust itself will function as a filter. The mass flow of air will stay clean and if there are remaining dust particles which enter the duct work, they will be caught by this thin film of dust.

Final Answer From HVAC Installer

Unless there was construction done in the home that generated a significant amount of dust or your home is dusty in general, HVAC installers recommend not to have your air ducts cleaned. They rely on religious filter changing and the ducts themselves functioning as a catch all for the remaining dirt and debris that get into the duct work. In addition, they are highly concerned about having the air duct cleaning equipment possibly damaging the duct work either by causing an air leakage or by puncturing a whole.

NADCA Certified Expert Take On Air Duct Cleaning

When a local air duct cleaning expert who is certified by the National Air Duct Cleaners Association or better known as NADCA, comes to clean your air ducts, the standard service will include the following: 

• Cleaning your furnace
• Cleaning the air conditioner coils
• Cleaning the supply and return ductwork
• Cleaning the floor and ceiling registers

During the service call, NADCA certified experts will use highly sensitive equipment when loosening the dirt and debris from the air ducts. When cleaning the steel vents they will use a vinyl whip and when cleaning flex ducts they will use an ultra sensitive rubber head so as not to cause any harm to the flex ducts. The head looks like a deflated  balloon which has just enough force to loosen the dust from the ducts without harming the flex duct. The point to be taken here is that certified air duct cleaners must use ultra sensitive equipment when cleaning both residential and commercial HVAC systems. 

NADCA White Paper On HVAC Cleaning & Energy Efficiency

In addition, to the primary benefit of having clean duct work, NADCA has done a white paper showing how cleaning your HVAC system can provide home owners with substantial savings on their energy bills. According to the white paper, homeowners saw a 38% increase in overall system energy performance when getting their air ducts cleaned. Though NADCA did not report the exact dollar savings due to the many variables like average temperature and cost per kilowatt, increasing your systems performance by 38% means that your system will in essence be running 38% less of the time. In most homes, it would be safe to say that you will see these savings on your next energy bill.  

How Is The Duct Cleaning Done?

NADCA has a process which is called source removal. This is done with both negative  and positive air flow. The positive air will loosen the dust from the ducts which will then get sucked up by the compressed negative air. All of the dust and debris which is loosened from the duct will be collected outside of the house. As a customer, always make sure that the dust is being collected outside the home and not inside the home. The last thing you want is for the dust and dirt to be pushed back directly into the living area.  

Beware of Air Duct Cleaning Scams!

I cannot express this enough, don’t hire someone to clean your home unless they are certified by NADCA. One of the things to look out for is the type of equipment which is brought into the home. If someone comes to your home and is claiming to clean your air ducts with just a Shop-Vac® that has a HEPA filter, don’t let them in. At best, they will clean the ceiling and floor registers and at worst they can damage the duct work with the hard plastic vacuum head. Do your homework and make sure that the air duct cleaning service comes highly recommended and don’t rely on social media. 

Using a Reputable Duct Cleaning Service

When using a trusted air duct cleaning service you can ask them all the questions in the world and they should provide you with satisfactory answers. After the service you can ask to see the filter in the equipment that catches the dust and dirt which will determine if the air duct cleaning was worth it. If the filter is clean then it was probably unnecessary but if it picks up lots of dust you most likely got your money’s worth.

How Much Should Air Duct Cleaning Cost?

Depending on the size of the home the pricing may vary. Bigger home might mean using multiple compressors and require much longer duct work. According to NewHomeSource the average square footage in a home is 2,500 square feet. Based on this number, the cost of getting a house of this size’s air ducts cleaned should cost between $300 and $400 dollars. Local air duct cleaners will tend to be closer to $300 and non local will most likely be closer to $400. Pricing may vary but it’s around this range where your cost should be at. When you see a price of anything less, please be cautious of this service and make sure to get a reference. 

Final Answer From Air Duct Cleaning Experts

Get your air ducts cleaned if you feel that it’s necessary and always make sure to hire a NADCA certified expert. Always be cautious if the price is lower than $300 and ask as many questions as you wish. Do your homework and make sure the service man comes highly recommended. Also, look out for the type of equipment being used and make sure that it’s not just a Shop-Vac® with a HEPA filter.

Keep In Mind The Decision Is Yours

Never feel pressured into having your air ducts cleaned. If you have done your homework and you feel it’s necessary, call up a reputable air duct cleaning service and have them explain the process. There are two schools of thought and HVAC installers will tend to shy away from getting their customers ducts cleaned unless there is an urgent need. This might be due to an over abundance of dust in the home or perhaps right after a home makeover. Other demands for air duct cleaning might be individuals who are allergic to dust and allergens.

Final Words

Both HVAC installers and local air duct cleaning experts agree on one thing which is to keep your house clean and don’t allow the build up of dust. This is especially important in homes which have carpet. I understand that carpet gives the home a cozy feel but it also is the primary producer of dust. This dust gets circulated throughout the home and can potentially end up in your ducts. Keeping your home clean is really important and make sure you vacuum those carpets religiously.

Your home’s air ducts work hard. In fall and winter, they push heat throughout the house. In summer, they switch gears and deliver cool air. Not only that, your HVAC system has a second set of ducts that returns air to the system for recirculation. 

So, it’s natural dirt, dust, pollen, bacteria, pet hair, mold spores, and even spiderwebs and vermin droppings will build up inside air ducts. Air duct cleaning rids HVAC ducts of unwanted solid matter, returning the ducts to like-new condition. But how much does air duct cleaning cost, and is it worth the expense?

How Much Does It Cost to Clean Air Ducts?

Depending on where you live and on the size of your home and its HVAC system, air duct cleaning costs $450 at the low end and ranges up to $1,000. The average cost of air duct cleaning is between $700 and $750.

Air Duct Cleaning Cost Averages

Additional Air Duct Cleaning Costs

• Extra Registers (Vents): Cleaning usually includes a set number of registers. Beyond that number may cost from $20 to $25 per register.
• Video Inspection: Running a remote video camera through the ducts for inspection typically costs from $200 to $500.
• Air Duct Sealing: Sealing air ducts with a special coating that plugs up leaks costs anywhere from $1,500 to $4,000 per treatment. Sealant is misted into the air ducts, covering all interior duct surfaces.
• Mold Remediation: Hiring a separate mold remediation company to eliminate mold from the air ducts costs between $2,000 and $6,000, depending on spread and damage caused.

How Often to Clean Your Home’s Air Ducts

Some air duct companies recommend that you clean your ducts every five to seven years, but both the U.S. Environmental Protection Agency (EPA) and the trade agency National Air Duct Cleaners Association (NADCA) recommend duct-cleaning only on an as-needed basis.

Conditions That Warrant Frequent Air Duct Cleaning

You may want to clean your air ducts more frequently if your home has specific conditions or situations, which can include:

• Tobacco or other recreational smoking
• Wood-burning fireplace
• Long-haired pets
• Pets with dander
• After major home remodeling
• After drywall or indoor carpentry work
• Residents who have respiratory conditions
• Ductwork that experiences internal moisture contamination
• After a home fire or wildfires

Tip

Though professionals may make broad claims about the health benefits of duct cleaning, the EPA notes that no studies have found cleaning to significantly improve the health of residents.

What Happens During Air Ducts Cleaning

Air duct cleaning is usually completed within one day. Most of the indoor work is complete within two or four hours.

1. Visual inspection of ducts and registers
2. Optional video inspection of ducts
3. Attach portable or truck-mounted vacuum collection device to a duct near air handler
4. Seal all registers
5. Turn on the vacuum collection device
6. Open each register individually and agitate dust in the ductwork
7. Clean each register and grille
8. Clean blower motor, evaporator coil, and drain pan

How to Know If Your Air Ducts Need Cleaning

Since it’s not necessary to regularly schedule air duct cleaning, you will need to keep an eye on the system. Clues that it’s time to clean your air ducts include:

System Blows Dust From Registers

After a period of long inactivity, the system may initially blow out dust. But generally, the grilles and supply registers in room ceilings and floors should always pump out clean air.  

Evidence of Vermin or Insects

Droppings from rats or mice or large infestations of insects will require air duct cleaning after the vermin or insects have been eliminated.

Visible Mold Growth

Mold in the air ducts can actively shed mold spores. When the air blows into the rooms, it carries the mold spores. 

Not all mold, though, produces health-threatening mycotoxins. If a solution of 1 part bleach and 16 parts water immediately clears the suspicious growth, it likely is mold. To definitively know, purchase a mold testing test or have a mold testing service (not a mold remediation company) visit your home.

How to Keep Your Air Ducts Clean and Maintained

Total system air duct cleaning is not a do-it-yourself job. The tools are specialized and cannot be duplicated with home tools. But you can—and should—maintain and partially clean your air ducts on a regular basis.

Clean the registers and especially the air return grille with the brush attachment of a shop vacuum. Equip the vacuum with a HEPA air filter. You can even remove the registers and clean the end foot or two of the ductwork.

Regularly replace your furnace’s air filter. To help the filter stay cleaner longer, convert your wood-burning fireplace to a ventless gas version, or remove it entirely.

Damp-mop the floor near the return register on a regular basis to prevent floor debris from being pulled into the system.

How to Choose a Duct Cleaning Professional

To pick an air duct cleaning company, begin by making sure that they are in good standing with NADCA. The organization’s Find a NADCA Professional page lists companies or individuals in your area, number of employees, how long they have been in business, and full contact information.

Is air duct cleaning worth it?

Air duct cleaning is worth it to save 10% to 30% on utility bills when maintenance includes changing filters, servicing all attached HVAC units, and eliminating contaminant sources. Cleaning air ducts also helps HVAC systems last longer and purify air better to reduce allergy symptoms.

What is duct cleaning?

Air duct cleaning removes all dirt, debris, pollutants, and hazardous materials from the entire ductwork ventilation system and all its heating and cooling system components. Air duct cleaning increases HVAC efficiency and can improve indoor air quality.

Duct cleaning service using a high-powered vacuum and soft brush

Professionals clean air ducts through these steps:

1. Inspecting ducts to check for hazardous materials
2. Spreading out drop cloths to protect home areas near vents while cleaning
3. Attaching a high-powered HEPA-filtered vacuum and blower to ducts
4. Dislodging debris inside the ducts
5. Extracting all dust and debris through the vacuum hose into an outside truck
6. Cleaning all supply and return vents

How often should you clean air ducts?

The National Air Duct Cleaners Association (NADCA) advises cleaning air ducts every 3 to 5 years. Other HVAC pros suggest cleaning every 5 to 7 years with well-sealed ducts. Cleaning frequency depends on duct conditions, climate, system usage, number of residents, and if people have respiratory issues.

Is air duct cleaning necessary?

Air duct cleaning is necessary and not a waste of money when excess dust or debris blocks the airflow, or when mold, mildew, or pest infestations are inside ducts. Cleaning ducts also effectively helps remove smells in homes with pets or smokers.

How long does air duct cleaning take?

Air duct cleaning takes 2 to 4 hours on average for a 2-person crew to clean one complete system. Larger or older homes take 3 to 6 hours. Cleaning times increase for homes with pets, complex HVAC systems, or contamination issues with mold, pests, or asbestos.

Do you tip vent cleaners?

You don’t need to tip vent cleaners, and some company policies don’t allow HVAC cleaners to accept tips. Most people offer workers drinks and restroom access. If the duct cleaning company performed an outstanding service, they appreciate a $10 to $20 tip.

How to tell if air ducts need cleaning

Air ducts need cleaning if these signs appear:

• Mold growth around vent covers
• Excess dust in the home
• Visible dust blowing out of the vents
• Rodent droppings or chewed areas around ducts
• Abnormally high utility bills
• Air filters clog up in less than a month
• Debris and dust collect near supply vents or in registers
• Inconsistent airflow in each vent
• Increased respiratory problems
• Unusual sounds when the HVAC blower runs
• Dust buildup on the furnace blower fan, furnace motor, or AC coils
• Musty smells in air vents

Does duct cleaning reduce household dust?

Duct cleaning does reduce household dust, but only if it came from leaky ductwork without air filters. Ducts are just one possible dust source. However, dust inside well-sealed and filtered air ducts shouldn’t enter home interiors. The EPA hasn’t proven that duct cleaning reduces health problems.

Reduce household dust effectively by:

• Installing a whole-house air purifier costs $400 to $4,000 on average.
• Using a vacuum with a high-efficiency particulate air filter, or HEPA filter
• Installing high-quality HVAC air filters on return vents
• Fixing all leaky ducts that take in attic or basement dust
• Putting screens on open windows and doors

Can air duct cleaning cause damage?

Air duct cleaning causes damages and lowers air quality when cleaners don’t use proper tools or methods. Cleaning flexible heat ducts requires a high-power vacuum and soft brush powered by compressed air—otherwise, the thin liner embedded inside flex ducts tears and leaks.

Damages caused by poor cleaning include:

• Tearing holes in flex-duct walls
• Loose duct connections that leak air
• Mold growth inside ducts from using wet sponges
• Releasing pollen, dust, and allergens into the home’s air
• Ripping off insulation inside ducts
• Broken seals around vent openings
• Fiberglass fibers from damaged liner spreading to contaminate indoor air

Can you clean air ducts yourself?

A licensed professional with high-power vacuums, rotary brushes, and other special equipment is necessary to clean air ducts thoroughly. Improper DIY duct cleaning damages the ducts, insulation, lining, and all connections in the HVAC system.

Decrease the need for duct cleanings by:

• Vacuuming around registers, duct openings, vent grills, and furnaces regularly
• Changing fiberglass air duct filters every 1 to 3 months
• Replacing pleated air filters every 3 to 6 months
• Removing metal vent covers for cleaning every 3 to 6 months
• Using a home air-purifier system
• Keeping air vents open as much as possible
• Checking ducts for leaks annually
• Cleaning AC coils annually
• Sealing ducts during renovations to keep out dust

This package of documents, upon request, is provided to the authorities of the Ministry of Emergency Situations and Rospotrebnadzor. Together with the ventilation cleaning contract, we recommend concluding a ventilation maintenance contract.

OUR SERVICES

Exhaust ventilation cleaning works are carried out at a convenient time for the Customer, most often at night (which allows not to stop the work of the Customer’s enterprise).

Our teams are staffed by specialists who are citizens of the Russian Federation, who have undergone special training and have permits to work on electrical safety and at height. Exhaust hoods, hood grease traps, air ducts, exhaust fans are cleaned. Before work, the premises are prepared, kitchen equipment is covered with plastic wrap. Measures are being taken to protect the electrical equipment of the kitchen. Insertion of inspection hatches, drainage valves in ventilation ducts is carried out.

For cleaning, specialized equipment from a European manufacturer is used, which allows high-quality cleaning of air ducts without dismantling in most cases. If necessary, an initial inspection of ventilation systems is carried out with the help of television inspection. Video recording is provided to the customer (optional).
This type of work is regulated by Article 16 of the Federal Law “On Fire Safety” and the Rules of the Fire Regime in the Russian Federation (approved by Decree N 390 of the Government of the Russian Federation of April 25, 2012).

Ventilation disinfection

The air usually contains particles of dust of organic and inorganic nature, on which various microorganisms travel through the air. Some of them (including those dangerous to health) find suitable conditions for existence in the ventilation system. As they multiply, they enter the indoor air, causing various diseases, such as Legionnaires’ Disease.

Routine ventilation cleaning does not eliminate these micro-organisms; disinfection must be carried out. According to the Decree number 4 of April 27, 2004 of the Chief Sanitary Doctor, once every six months, all organizations, regardless of ownership, are required to conduct a sanitary-epidemiological examination of ventilation systems using laboratory methods. In case of detection of pathogenic microflora, disinfection is carried out.

Disinfection of ventilation and air conditioning is carried out after preliminary cleaning of ventilation. A working solution of a disinfectant is prepared and sprayed on the surfaces. Disinfectants approved for use in the Russian Federation for disinfection of ventilation and air conditioning systems are used. After irrigation, it is not necessary to rinse the product with water, as it decomposes into carbon dioxide and water within a short period of time. Our organization has experience in performing complex tasks in the field of disinfection of ventilation systems.

Soot cleaning

Chimney cleaning is relevant both at public catering facilities (exhaust hoods from kitchen equipment) and in the field of individual housing construction (dachas, cottages, etc. ) and implies a set of measures, including:
– Preliminary examination, including tele-inspection if necessary
– Cleaning the exhaust hoods of barbecues, stoves
– Cleaning the chimney directly

Ecolife Group of Companies specialists will always come to your aid in cleaning chimneys from soot, grease and other contaminants (cleaning chimneys of stoves, fireplaces, cleaning chimneys of barbecues and other chimneys). As a rule, exhaust hoods and hydraulic filters (if installed) are cleaned along with chimneys.
Cleaning of chimneys is carried out with special brushes with a flexible or rigid handle and electric drive. Depending on the material of the chimney walls and the degree of its contamination, different types of brushes (plastic, abrasive, metal) are used. In addition, dry cleaning (the brush cleans the inner walls of the chimney) and cleaning with reagents (liquid is preliminarily introduced into the chimney, which contributes to faster and more efficient cleaning) can be carried out.
This type of work is regulated by Article 16 of the Federal Law “On Fire Safety” and the Fire Safety Rules in the Russian Federation (approved by Decree N 390 of the Government of the Russian Federation of April 25, 2012).

Cleaning and disinfection of air conditioners
Cleaning and disinfection of air conditioners

In air conditioning systems, outdoor unit heat exchangers become clogged with dirt, dust, fluff, indoor heat exchangers and drainage baths become a breeding ground for pathogenic bacteria and mold.

Mechanical contamination of the heat exchanger reduces the cooling capacity of the air conditioner, increases the load on the compressor and, as a result, reduces the service life of your air conditioner. Cleaning of the air conditioner should be carried out twice a year and is part of the manufacturer’s maintenance schedule.

Microbial contamination in some cases leads to acute pneumonia, in others causes chronic respiratory diseases, reduced immunity, allergies.

Disinfection of ventilation and air conditioning should be carried out twice a year (usually together with ventilation maintenance) and controlled by the Rospotrebnadzor authorities.

Inspection of ventilation systems before cleaning. Video inspection (television) of air ducts and chimneys

Teleinspection of ventilation and chimneys

TV inspection is used to diagnose air ducts and chimneys. With the help of a video camera, it is easy to assess the condition of the air ducts, the degree and type of pollution, after the work performed, the quality of ventilation cleaning is assessed. Also, the pipe inspection method is used to diagnose any other pipelines, such as sewers. The study is recorded and provided to the Customer.

A tele-inspection of ventilation systems is required to:

• determine if the ventilation or chimney is contaminated with dirt. dust, grease or soot;
• assessing the quality of ventilation cleaning;
• detection of damage, blockage or foreign object in the air duct;
• specifying the position and nature of the defect;
• Assess the condition of the entire ventilation duct before repairing or replacing the damaged area.

VIDEO: TV inspection of ventilation ducts

While after the cleaning activities, when the operation of the system returns to the design mode, positive changes are more than obvious and often cause surprise on the part of the Customer. Indeed, how much more air began to enter the room, how much more efficiently the duct air conditioner began to work, and also how much quieter the fan began to work, it is impossible not to notice.

Why is ventilation dust dangerous?

What is dust? Dust is small particles of organic and inorganic nature that are suspended in the air and settle on the surface. Why is dust dangerous? Getting into the human bronchi during breathing, dust can cause various diseases such as allergies and asthma, in addition, various microorganisms “travel” on dust particles through the air, causing the spread of infectious diseases. In addition to the above problems, dust is a flammable agent. Accumulating in the ventilation ducts, dust can instantly ignite from the slightest spark, forming an explosion. After completion of construction or repairs, as a rule, a significant amount of construction dust enters the ventilation ducts, which should be disposed of before the building is put into operation.

How ventilation and air conditioning are cleaned

The ventilation system is cleaned in segments of 5-30 m. . This dust is immediately evacuated by a vacuum machine and settles in the filter unit.

In this way, no dust is released into the environment during cleaning. Cleaning is carried out without dismantling the air ducts and as soon as possible.

If necessary, a video inspection of the air ducts is carried out to determine the degree of contamination and the results of cleaning. This technique is used all over the world and is recognized as the most efficient and environmentally friendly.

After cleaning, disinfection is carried out if necessary. Also, in addition to air ducts and air handling units, air conditioners are subject to cleaning and disinfection.

The working shift is 8 hours, of which 1 or 2 hours is the time of delivery (arrival), and 6 or 7 hours is the net working time of the brigade at the facility. Working shift when ordering works in Moscow (within the Moscow Ring Road) 7 + 1 hour. Working shift when ordering works in the Moscow region 6 + 2 hours.

* The 8-hour work shift includes not only the time that Comservice employees are at the facility, but also the road to it. In Moscow (within the Moscow Ring Road) travel time is equal to 1 hour, in the Moscow region – to 2 hours.

High-quality cleaning of ventilation is possible only if access to all air ducts is provided. It is better to think over this issue in advance, since the working time of specialists is paid, and the more rationally it is spent, the lower the final estimate. 9Service

The Revensis company is engaged in professional cleaning of ventilation of restaurants, industrial facilities, office and residential buildings in St. Petersburg. We have everything you need for high-quality cleaning of grease ventilation in cafe kitchens, removing dirt from the ventilation ducts of industrial premises and cleaning ventilation from dust in MKD. We carry out cleaning of ventilation and air conditioning systems in accordance with the law and established standards.

Ventilation cleaning intervals

Any technical system eventually breaks down. An idle ventilation system is a threat to human health. The lack of air exchange with the environment contributes to the spread of infections, the development of oxygen starvation, and deterioration of health. The ventilation ducts are cleaned at intervals set depending on the type of facility and type of ventilation:

• Cleaning of ventilation ducts in an apartment building with natural air exchange is done once every 3 years.
• Cleaning of industrial ventilation is carried out more often: about 1 time per month.
• The frequency of cleaning the ventilation from combustible waste is 2 times a month.
• Cleaning of air ducts from grease; at catering establishments should be carried out from 1 time per month.

At manufacturing enterprises, the frequency of cleaning process ventilation ducts is determined by responsible persons based on the specifics of production.

“Revensis” provides services for the repair and cleaning of ventilation in apartment buildings, cleaning of cafe ventilation systems, cleaning of industrial ventilation. We work in hotels, office buildings, shopping centers and other buildings equipped with ventilation systems.

We have already been contacted

Cleaning ventilation in restaurants and cafes

Timely cleaning of ventilation in a restaurant is necessary to comply with sanitary standards. In catering establishments, ventilation ducts get dirty especially quickly and strongly. This is due to the release of fat during cooking, which settles on the walls of the duct and attracts dust. Without regular cleaning of the exhaust ventilation from fat deposits:

• the intensity of air exchange decreases;
• dangerous conditions for work and health are formed;
• a fire hazardous situation is created, especially this applies to hoods from barbecues;
• there are unpleasant odors in the hall;

Grease-free restaurant ventilation eliminates all of these problems.

In addition to cleaning, our specialists carry out disinfection of ventilation systems. For more information about the service, see the “Disinfection of ventilation” section.

Ventilation duct before and after cleaning

Cleaning ventilation systems in apartment buildings and offices

Cleaning ventilation in apartments and office buildings is necessary to maintain a healthy microclimate. Without it, health worsens, the risk of developing chronic diseases increases. Humidity rises in the premises, mold and a musty smell appear.

In the kitchens of apartments, houses and offices, it is required to clean the ventilation from fat deposits. In other rooms, air ducts are being cleaned from dust. We recommend combining the cleaning of ventilation in a house with the cleaning of chimneys in apartment buildings.

Ventilation system cleaning methods

The choice of ventilation duct cleaning method depends on the type of ventilation system and its pollution. We clean channels:

• The classic way. Involves the use of the core on a rope with a brush attached to it. Suitable for cleaning ventilation in houses with short vertical ducts.
• Brush machines. This method is used to clean the ventilation of companies, cleaning ventilation in cafes. It consists in the use of special equipment with rotating brushes that quickly remove grease and dust deposits. Detergents are used to effectively clean the air from fatty deposits.

Our company provides comprehensive services for the repair and cleaning, disinfection of ventilation: see the prices for services in the table.

Our ventilation cleaning equipment

For cleaning the air ducts of ventilation systems we use:

• Air duct cleaner LIFA AIR COMBI CLEANER 40R with pneumatic drive, 40 m shaft, which allows cleaning long air ducts and diameters from 250 to 1200 mm
• Electrically driven flexible shafts of various lengths and stiffness, which are usually used for air ducts with small diameters (up to 400 mm. )
• Reel Jet is a brushing machine that can be used to clean duct sections up to 40 m long with a cleaning solution placed in a 10-liter tank.

Vene systems cleaning costs

The price for ventilation cleaning services is formed taking into account the type of system, cleaning area and degree of contamination. Therefore, the price of ventilation cleaning in apartment buildings is inferior to the price of a service in industrial buildings. The cost of cleaning the supply and exhaust ventilation is higher than the price of cleaning natural ventilation.

Expert advice

When and where to clean ventilation systems

Cleaning and disinfection of ventilation and air conditioning systems is an important anti-epidemiological and preventive measure. A polluted ventilation shaft is an excellent breeding ground for pathogens, mold and mildew. Pathogens multiply in such conditions at a tremendous rate, becoming a potential threat to the health of a large number of people.

In addition, a dense layer of dust, dirt, grease and burning creates a fire hazard. It is worth one spark to get on the contaminated surface of the mine, ignition will start and, as a result, a fire.

Timely and regular cleaning of ventilation systems by professional services is necessary to avoid possible problems.

Order processing Read interesting articles

Once every 6 months, a sanitary and epidemiological study and inspection should be performed, based on the results of which the issue of the need for cleaning and disinfection of ventilation ducts is decided.

Cafes and restaurants where ventilation systems are more likely to accumulate fat deposits should be treated at least once every 3 months. If the kitchen is working with a small load, then cleaning can be done once every six months.

For residential and industrial premises, cleaning and disinfection of ventilation is carried out as necessary, but at least once a year.

To determine the quality of air exchange, disinfectors use a special animometer device that determines the speed of air movement at the entrance to the ventilation shaft. The result obtained is compared with acceptable standards and the need to clean the systems is established.

The cost of cleaning ventilation and air ducts

The cost of cleaning is calculated individually for each object, depending on the number of ventilation systems, the length of air ducts and the area of ​​ventilation shafts.

The final price depends on the size and current condition of the ducts, the number of branches and turns, etc.

The exact calculation and the final cost can be found by calling 8-922-517-04-89, or by leaving a request for a call back on the website of the company “ECO SES”.

Cleaning of ventilation systems is necessary for their proper functioning. They regularly pass large volumes of air through themselves, which is why dust, dirt and other sediments accumulate on the walls. This reduces the efficiency of its work, and with a weak throughput, it completely blocks the air circulation. Therefore, regular cleaning of ventilation is a mandatory procedure to ensure the normal operation of this system.

Clean ventilation is necessary for fire safety, and in medical institutions and is completely mandatory, because the health of patients and employees depends on it. Therefore, do not neglect this.

The need to clean ventilation systems

During operation, dust and grease deposits accumulate in the air ducts and equipment of ventilation systems, which makes it difficult to maintain the set air parameters. Contaminated air ducts of ventilation and air conditioning systems create the possibility of fires. Accumulated deposits of dust and grease in ventilation equipment and air ducts ignite easily, and with the movement of air inside the air ducts, the fire quickly spreads throughout the building.

If the ventilation system, in addition to transporting air, is designed to heat, cool and humidify it, then the accumulated dust deposits create favorable soil for the growth of mites, bacteria, fungi and other microorganisms dangerous to humans. Over time, microorganisms can break away from the surface of the air ducts and be carried by the air flow into the serviced premises. Diseases such as allergies, influenza, and SARS can be transmitted through ventilation from an infected person to a healthy person.

Examination of ventilation systems

Examinations are carried out using multimeters (flow rate, temperature, humidity, dust concentrations by particle fractions), sound level meter and video equipment in order to determine the condition of vertical and horizontal channels, the causes of inefficient ventilation, as well as to control the quality of cleaning ventilation ducts.

Methods of work carried out are based on GOST, ISO and industry-specific MU. During the examination, a high-sensitivity video camera mounted on a self-propelled minitractor is used. The image is fed to the monitor, which allows you to quickly assess the condition of the air ducts, as well as record the examined areas on a video cassette.

After cleaning, a second video diagnostic of the air ducts is carried out, the record is attached to the protocol of work. According to the results of the examination, a report on the conducted studies, an examination protocol is drawn up. If necessary, recommendations are given on the creation of air purification systems in supply and exhaust ventilation systems and for solving technological problems.

Cleaning of ventilation systems

After determining the degree of contamination of vertical and horizontal channels, a work plan is drawn up with a list of equipment used. Cleaning of the air handling unit of the ventilation system, as well as its individual components, is carried out using compressed air and high-performance industrial vacuum cleaners.

Air ducts are cleaned mechanically and chemically. Cleaning equipment consists of a wide range of installations and tools for solving specific tasks:

• pneumatic drive unit with turbine for rotating the brush,
• electromechanical cleaning plant,
• air duct chemical treatment plant,
• high pressure vacuum and pressure unit,
• filtration unit, etc.

This method of cleaning ventilation ducts is effective and safe. It allows you to clean the air ducts without dismantling and not pollute the premises, due to the use of highly efficient filtering units.

You can do this work yourself, but it is important to remember that for this you need to use specialized equipment, without which it will be difficult to get the perfect result. It is also important to know exactly what elements the entire system consists of, as a result of which it will be necessary to take care of cleaning each component.

The most common degreasing is done, which is quite simple, but if you concentrate on this work, it is recommended to immediately implement other related work to get a comprehensive cleaning. It is important not only to get rid of grease and dust, but also from various deposits of bacteria and microbes. If there are any blockages in the air ducts at all, then they must be promptly eliminated, since in most cases they cause serious problems with indoor air. It is best to have at your disposal unique video equipment that will allow you to easily diagnose mines and channels.

How is ventilation cleaned from dust and other contaminants? To do this, it is important to clean the following items:

• Cleaning of ventilation shafts and chambers;
• Valve handling;
• Removal of deposits inside the impeller of machines for extracting or supplying air;
• Cleaning of contaminants accumulating in air ducts with both large and small sections;
• Replacement of various filters as needed.

The most significant difficulties usually arise when cleaning the crankcase ventilation, and also when working with air ducts located in very tall and large buildings, since they are located at a significant height and also have a significant diameter. In this case, it is mandatory to have special equipment for this work. In order to get the perfect cleaning result, it is important to constantly use various brushing machines and just ordinary hand brushes, which must have different degrees of hardness and sizes, because then the most optimal option can be selected for a certain contamination. Also, if you have to work in large channels, then you need to wear special protective clothing.

The cleaning process itself takes place in several stages:

• Assessment of the condition of the existing ventilation system;
• Finding suitable equipment and other cleaning supplies for the job;
• Direct cleaning of fat deposits and other contaminants, and for this a mechanical or chemical method can be used, and in the first case a variety of equipment is used, and in the second different chemical reagents;
• Evaluation of the work carried out, on the basis of which it can be decided whether it should be supplemented with other stages or whether an ideal result was achieved.

Cleaning of fire hazard deposits

Contaminated ventilation and air conditioning systems create the possibility of fires. Accumulated deposits of dust and grease in the ventilation equipment and air ducts are easily ignited, and with the movement of air inside the air ducts, the fire quickly spreads throughout the building.

The most dangerous from the point of view of fire are the air ducts of the exhaust systems from the equipment of the kitchens of restaurants, cafes, etc. Often the cause of a fire is the untimely cleaning of kitchen umbrellas and air ducts from fat deposits accumulated in them.

In many national cuisines there are dishes prepared in “live” fire. During the preparation of such dishes, the flame can easily spread from the dishes in which the dish is cooked to the grease traps of the kitchen umbrella and move inside the ventilation system to other rooms. Removing grease from the air duct behind the kitchen umbrella is quite a laborious job, so the air duct is often left unattended.

Every building that has an exhaust system above kitchen equipment has a potential fire risk.

What equipment is used in the process of cleaning ventilation systems?

Ventilation cleaning equipment today is extensive and quite popular, so choosing the right one is really not so easy. However, if you intend to do all the work yourself, then you can pick up the most basic and standard components that will remove dust, grease and blockages in mines and other parts of the system. These include:

1. Core with which you can check the channels for deposits or blockages;
2. A bar that is highly flexible yet allows easy access to ventilation areas that are horizontal and therefore difficult to access;
3. Brushing machine, which, if desired and available, can be replaced with different manual brushes;
4. Canal Punch that easily clears blockages, and they can even be made from bricks or building debris;
5. A video surveillance system that will provide information about where blockages or deposits are in the system.

How often should the ventilation system be cleaned?

Cleaning intervals may vary for different systems. It is best if this complex work is carried out at least once every six months, however, the system is often used very often, and as a result, purification will need to be carried out more often. If there is a special industrial enterprise at all, where impurities in the air constantly arise, which are eliminated with the help of a ventilation system, then purification work should be carried out about once or twice a month. Fine filters can easily tell you when to replace them, because they will easily show various dirt and deposits. In this case, you can independently decide when the need for cleaning work arises.

Detergents and disinfectants

Professional cleaning of air ducts from grease and other harmful deposits is carried out with the help of specialized chemicals:

• aggressive alkaline compounds for cleaning channels with foam;
• neutral powder detergents for removing deposits by soft blasting.

Clarification. Blasting is a procedure similar to sandblasting the pollutants. Only instead of sand, fine chemical powders are used that do not damage the zinc coating of the ventilation duct. The technology is effective, but quite expensive.

Alkaline products are sprayed inside the air ducts beforehand or during the cleaning process. Under the influence of the reagent, fats and soot decompose, the sediment is washed off with water.

The type and concentration of disinfectant antiseptics is selected according to the results of the study of samples (so-called swabs). The latter are taken at the stage of inspection or primary cleaning of air ducts and sent to the laboratory.

Ventilation cleaning technology

At the first stage, a clean-up plan is drawn up. The ventilation scheme is being studied, the places for connecting machines, the points for setting plugs and the amount of installation work are determined.

Note. In the process of servicing the ventilation system, one cannot do without partial disassembly and reassembly of the elements. Example: to connect a pipe from a vacuum pump, you need to remove the inspection hatch or disconnect the fitting of the air duct. If there are no hatches at the right points, installers cut openings in the channels and put tight covers.

In addition to air ducts, the following ventilation elements are subject to cleaning:

• intake and exhaust devices – grilles, diffusers, local exhaust hoods;
• fire-retarding and check valves, control dampers;
• heat exchangers for heaters, recuperators and central air conditioners;
• fan parts in contact with the air flow – impellers, turbines;
• grease filters designed for regeneration (recovery).

The equipment and ventilation network are also cleaned from the outside. Cell, bag and bag type filters are completely replaceable. Upon completion of the work, the organization draws up an act approved by the customer.

The process for dry cleaning of the air duct network looks like this:

1. The vacuum machine is connected by a hose to the main air line, usually next to the fan. Extended collectors of large diameters are divided into sections of estimated length comparable to the productivity of the machine.
2. The filter block is connected to the vacuum fan with a second corrugated pipe.
3. Ventilation grilles are removed along the entire length of the serviced area, branches of a smaller diameter are disconnected. The holes are tightly closed with plugs.
4. The operator of the brushing machine, dressed in a protective suit and respirator, pulls a flexible shaft with a cleaning tool into the channel from the other side. To remove fat, an alkaline reagent is pre-sprayed there.
5. Both units are started and the air duct is cleaned. Dust and soot, removed from the walls with a rotating brush, is sucked up by a vacuum unit. Dirty air is supplied through a pipe to a filter unit that traps all particles.
6. The operation is repeated on subsequent sections in the same way.

Note. If the ventilation system is properly designed, it will not be necessary to disconnect the air ducts. On the branches from the collector there will be dampers that can be covered.

Documentation when cleaning the ventilation

Cleaning the ventilation is a necessary procedure that contributes to its normal functioning. Therefore, the frequency of such work is indicated in the Fire Safety Rules of the Russian Federation, namely in paragraph 50. It states that such work should be carried out at least once a year. As for medical institutions, there this procedure must be performed every six months for air intake shafts and once a month for ventilation chambers.

Therefore, the procedure for cleaning such systems is important and must be approved by official organizations or companies providing such services. When cleaning yourself, it is worth carrying out appropriate tests confirming the quality of the work performed. In addition, documentation is carried out in this area, namely:

• Types of work that are carried out during revision or cleaning.
• Revision and cleaning schedule.
• Act of the result of cleaning its revision.

The act may be accompanied by the results of a ventilation test for efficiency, as well as an act of acceptance of the system into operation. It is extremely important to draw up documentation, because it will be needed when checking the fire inspection, if the house is used by some organization or company.

Important! The act should not be drawn up after the work has been completed, but on the basis of tests that prove the effectiveness of the ventilation.
