Cleaning anything creates at least a small amount of clutter. The air duct is no exception in this case. And then air ducts are placed over your house. Therefore, when you clean them with a high suction machine, you will see some debris and dust inside your house.
Does air duct cleaning work? It does. However, it must be performed by qualified professionals and correctly. Sometimes, duct cleaning can be a complicated and costly process. To do it right, all components of the duct system must be removed and cleaned.
Cleaning contractors use portable or truck-mounted vacuum collection devices that suck debris and dust from the ductwork. All loose debris gets into the HEPA vacuum without dropping it into your home when done correctly. Dust comes from many sources, including pet dander, dust mites, entrained dirt, and blown pollen. While it's true that the ducts in your home may contain dust, the particles often stick to the inside of the ducts and don't come off when the oven or air conditioner is running.
Carpets, upholstery, and curtains can contain higher levels of dust particles, and simply walking around the room can generate more dust than the small amount that comes from air ducts. Unless a family member is allergic to dust and wants to take special precautions beyond using a HEPA vacuum cleaner, duct cleaning may not make a difference, from a health standpoint, in indoor air quality. In some cases, discussed below, cleaning the ducts is a good idea. An official website of the United States Government Official websites use.

Knowledge about cleaning air ducts is in its early stages, so a general recommendation cannot be offered on whether you should clean the air ducts in your home. The Environmental Protection Agency (EPA) urges you to read this document in its entirety, as it provides important information on the subject.
Duct Cleaning Has Never Been Proven To Actually Prevent Health Problems. Nor do studies conclusively show that the particle (for example,. This is because much of the dirt from the air ducts adheres to the surfaces of the ducts and does not necessarily enter the living space. It is important to note that dirty air ducts are just one of many possible sources of particulate matter that are present in homes.
Contaminants that enter the home from both outdoor and indoor activities, such as cooking, cleaning, smoking, or simply moving around, can cause greater exposure to pollutants than dirty air ducts. In addition, there is no evidence that a small amount of household dust or other particles in the air ducts poses any risk to your health. If any of the conditions identified above exist, it usually suggests one or more underlying causes. Before any cleaning, adaptation or replacement of your ducts, the cause or causes must be corrected or, otherwise, the problem is likely to recur.
Some research suggests that cleaning heating and cooling system components (for example,. However, there is little evidence that cleaning just the ducts will improve system efficiency. You may consider cleaning the air ducts simply because it seems logical that the air ducts become dirty over time and be cleaned from time to time. As long as cleaning is done correctly, there is no evidence to suggest that such cleaning is harmful.
EPA does not recommend that air ducts be cleaned routinely, but only when necessary. However, the EPA recommends that if you have a furnace, stove, or fireplace that burns fuel, it be inspected for proper operation and serviced before each heating season to protect against carbon monoxide poisoning. If you decide to have your air ducts cleaned, take the same consumer precautions that you would normally take when evaluating the competence and reliability of the service provider. Whether or not you decide to clean the air ducts in your home, preventing water and dirt from entering the system is the most effective way to prevent contamination (see How to Avoid Duct Contamination).
If you decide to clean your heating and cooling system, it is important to ensure that the service provider agrees to clean all components of the system and is qualified to do so. In addition, the service provider can propose the application of chemical biocides, designed to remove microbiological contaminants, inside ducts and in other components of the system. Some service providers may also suggest applying chemical treatments (sealants or other encapsulants) to encapsulate or cover the inner surfaces of air ducts and equipment housings because they believe they will control mold growth or prevent the release of dirt particles or fibers from the ducts. These practices have not yet been fully investigated and you should be fully informed before deciding to allow the use of biocidal products or chemical treatments in your air ducts.
They should only be applied, if any, after the system has been properly cleaned of all visible dust or dirt. Knowledge about the potential benefits and potential problems of air duct cleaning is limited. Since the conditions in each home are different, it is impossible to generalize whether cleaning the air ducts in your home would be beneficial or not. On the other hand, if family members are experiencing unusual or unexplained symptoms or illnesses that you think may be related to your home environment, you should discuss the situation with your doctor.
EPA has published the following publications for guidance on identifying potential indoor air quality problems and ways to prevent or address them. While the debate over the value of regular duct cleaning continues, there is no evidence to suggest that such cleaning is harmful, provided it is done correctly. On the other hand, if a service provider does not follow proper duct cleaning procedures, duct cleaning can cause indoor air problems. For example, an inadequate vacuum collection system can release more dust, dirt and other contaminants than if you had left the ducts alone.
A careless or poorly trained service provider can damage your ducts or heating and cooling system, possibly increasing your heating and cooling costs or forcing you to perform difficult and costly repairs or replacements. This is because much of the dirt that can accumulate inside the air ducts adheres to the surfaces of the ducts and does not necessarily enter the living space. In addition, there is no evidence that a small amount of household dust or other particulates in the air ducts poses any health hazard. The EPA does not recommend that air ducts be cleaned except as necessary due to ongoing uncertainty about the benefits of duct cleaning in most circumstances.
Some research also suggests that cleaning dirty cooling coils, fans, and heat exchangers can improve the efficiency of heating and cooling systems. However, there is little evidence that simply cleaning the duct system will increase the efficiency of your system. If you think duct cleaning may be a good idea for your home, but you're not sure, talk to a professional. The company that serves your heating and cooling system can be a good source of advice.
You can also contact professional duct cleaning service providers and ask them about the services they provide. Remember that they are trying to sell you a service, so ask questions and insist on getting complete and knowledgeable answers. A thorough visual inspection is the best way to verify the cleanliness of your heating and cooling system. Some service providers use remote photography to document conditions inside ducts.
All parts of the system must be visibly clean; it must not be able to detect any debris with the naked eye. Show Consumer Checklist After Cleaning to Service Provider Before Work Begins. After you complete the job, ask the service provider to show you each component of the system to verify that the job was successful. Whether or not you decide to clean your home's air ducts, it's essential to commit to a good preventive maintenance program to minimize duct contamination.
There should be no moisture in the ducts. Controlling humidity is the most effective way to prevent biological growth in air ducts. You may be familiar with air ducts that are made of sheet metal. However, many modern residential air duct systems are constructed of fiberglass panels or sheet metal ducts that are lined on the inside with a fiberglass duct liner.
Since the early 1970s, there has been a significant increase in the use of flexible ducts, which are usually lined internally with plastic or some other type of material. Experts agree that moisture should not be present in the ducts, and if there is moisture and dirt, there is a possibility that biological contaminants will grow and spread throughout the house. Controlling humidity is the most effective way to prevent biological growth in all types of air ducts. Air duct cleaning service providers can tell you that they need to apply a chemical biocide inside the ducts to kill bacteria (germs) and fungi (mold) and prevent future biological growth.
Some duct cleaning service providers may propose to introduce ozone to remove biological pollutants. Ozone is a highly reactive gas that is regulated in outdoor air as a lung irritant. However, there remains considerable controversy over the necessity and wisdom of introducing chemical biocides or ozone into pipelines. While some low-toxic products may be legally applied while the occupants of the house are present, you may want to consider leaving the premises while applying the biocide as an additional precaution.
Manufacturers of products marketed to coat and encapsulate duct surfaces claim that these sealants prevent dust and dirt particles inside air ducts from being released into the air. As with biocides, a sealant is often applied by spraying it into the operating duct system. Laboratory tests indicate that materials introduced in this way tend not to completely cover the surface of the duct. The application of sealants may also affect the acoustic (noise) and fire retardant characteristics of ducts lined or constructed with fiberglass and may invalidate the manufacturer's warranty.
Most organizations dealing with duct cleaning, including EPA, NADCA, NAIMA and the National Association of Sheet Metal and Air Conditioning Contractors (SMACNA), currently do not recommend the routine use of sealants to encapsulate contaminants in any type of duct. Cases where the use of sealants to encapsulate duct surfaces may be appropriate include repair of damaged fiberglass insulation or when combating fire damage within ducts. Sealants should never be used on wet duct lining, to cover actively growing mold or to cover debris in ducts, and should only be applied after cleaning in accordance with NADCA or other appropriate guidelines or standards.

Duct cleaning can make a mess if not done professionally. Remember, duct cleaning involves removing dirt from the ductwork and directing it somewhere else for safe disposal. The Environmental Protection Agency and Canadian Mortgage and Housing Corporation agree that you don't have to have your ducts cleaned in any particular program, so it's not a necessary part of your annual home maintenance routine. A competent and NADCA certified duct cleaning company will always take the time to properly seal ventilation grilles, keep duct cleaning equipment clean, and protect carpets and home furnishings from vacuum hoses.
The air ducts are connected to the ventilation grilles in your home and, during the cleaning process, debris will come out through all the ventilation grilles. All of these types of ducts include sheet metal distribution cables to help properly direct airflow to different areas of the house and balancing dampers to properly distribute airflow, sealant, straps and adhesive tape to secure ducts properly. Keeping your air ducts clean is no different, in fact, it is very important to keep the air flow clean through your home. The ducts come out of the oven and through basements, access spaces and walls to reach all rooms, and cleaning them involves vacuuming dust and debris, as well as removing mold (if present).
If your goal is to make indoor air as fresh and healthy as possible, you may want to consider hiring a company to clean the air ducts in your home, the long channels that carry hot or cold air throughout the house. Asbestos could be present in older homes and would need to be removed before cleaning, as it is known that inhaling asbestos contains cancer-causing material that will spread through the air during the duct cleaning process. If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty smell or visible mold growth), clean the air ducts probably is unnecessary. Untrained technicians or fraudsters who lack the proper vacuum equipment to safely clean ducts can dislodge dust previously adhered to the inside of ducts and release it into your home.
Duct cleaning refers to the process of cleaning various parts of your forced air heating and cooling system to remove dust and other particles. Therefore, the EPA recommends that ducts be cleaned after vermin infestation or water damage, or if you see or smell mold. Consider adding or upgrading your air purification system once odors are removed to help keep the air in your home healthy and clean. You may think that regular cleaning of air ducts is a good way to ensure cost-effective heating and cooling and avoid unnecessary repairs.
