By cleaning your air ducts during the spring, you can keep your system efficient and your energy bills low during the summer. As mentioned above, your ducts can collect dust, mold, pollen, and any number of contaminants that enter your home. An official website of the United States Government Official websites use. gov A.
gov belongs to an official government organization in the United States. 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.

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. Office of Radiation and Indoor Air Division of Indoor Environments (6609J) 1200 Pennsylvania Avenue, N, W. Air ducts may also contain some harmful microorganisms.
If you have children or live with older people or people with compromised immune systems, recirculation of pollutants in the air can cause adverse health problems. When pet dander, animal fur, mold spores and pollen enter the house, they can trigger allergic symptoms and asthma attacks. A regular cleaning of the air ducts will help prevent allergens from circulating throughout the house, creating healthier living conditions. Cleaner air also makes breathing easier.
This will reduce sick time, medical bills and levels of discomfort. One of the main benefits of cleaning air ducts is that it will improve the air quality in your home. This is especially important if your home is home to people who are sensitive to poor air quality, such as children, the elderly, and people with asthma or allergies. There are many devices that can monitor the air quality in your home, but people with allergies have a much more sophisticated system, such as the eyes, nose and throat (ENT).
These senses are irritated and cause great discomfort, and sometimes even make it difficult to breathe. People who are allergic to dust often have sneezing attacks, watery eyes, and a runny nose. In chronic and more severe cases, such as those with asthma, shortness of breath, chest tightness and wheezing may occur if you are allergic to dust. According to NADCA, the air in a house can circulate on average five to seven times a day.
If there are contaminants or allergens inside the air ducts, this can have a negative impact on your home's air quality. Keeping ducts and vents free of dust, mold and allergens will improve air quality for everyone. Did you know that your home generates approximately 40 pounds of dust each year? If you are wondering where that dust is going, the answer lies in the air ducts and in the cold or warm air that is pumped into each and every room in your house. The dirtier the duct system becomes, the more difficult the HVAC unit must work to push air through the ducts and keep it circulating evenly throughout the house.
The engine of your HVAC system will experience less wear and tear if its work is facilitated by clean ducts. With residential vent cleaning services and regular system cleaning, these allergens and dust mites can be removed from the system before they have a chance to circulate in the air you breathe. Cleaning the ducts will often help to remove these harmful particles, improve indoor air quality and protect the health of your family members. There are many benefits to disinfecting air ducts that can have a positive impact on the performance of your HVAC systems and the air quality of your home.
If you've been delaying cleaning your air ducts, check out these six benefits for your home's heating and cooling seasons. In addition, if someone in your family is struggling with allergy symptoms or asthma or other respiratory problems, cleaning the air passages can help relieve symptoms. While there is some benefit to cleaning and maintaining HVAC equipment, that benefit is relatively small and the little energy waste can be attributed to dirty ducts or equipment. If you are looking for professional duct cleaning services, the technician will check the entire duct network for other problems.
If you're not sure when your air ducts were last cleaned, schedule a duct cleaning now and get back on your way to a cleaner home. Cleaning the air conditioning ducts will safely remove any external particles that have arisen during the construction of the house. Duct cleaning methods vary, although industry associations dealing with air duct cleaning have established standards. Cleaning the air ducts removes all debris from inside the air ducts, including any musty odors that have developed over time and any mold that may have grown, resulting in a fresher smelling home.
