Are you considering having your air ducts cleaned in Miami-Dade County, FL? It's important to understand the potential environmental benefits of air duct cleaning before making a decision. While there is no conclusive evidence that air duct cleaning can prevent health problems, it can help reduce the amount of dirt and other particles in the air. The Environmental Protection Agency (EPA) recommends that you read this document in its entirety to learn more about the subject. The EPA does not suggest that air ducts be cleaned routinely, but only when necessary.
This is because much of the dirt that accumulates inside the air ducts adheres to the surfaces of the ducts and does not necessarily enter the living space. In addition, there is no proof that a small amount of household dust or other particles in air ducts poses any health risk. However, if any of the conditions identified above exist, it usually implies one or more underlying causes. Before cleaning, reconditioning, or replacing the ducts, the cause or causes must be corrected, or else the problem is likely to reappear.
Some research indicates that cleaning the components of the heating and cooling system (e.g., cooling coils, fans, and heat exchangers) can improve the efficiency of heating and cooling systems. However, there is little evidence to indicate that simply cleaning the duct system will increase the efficiency of the system. If you decide to have your air ducts cleaned, take the same consumer precautions you would normally take when evaluating the competence and reliability of the service provider. You may want to consider cleaning your air ducts simply because it seems logical that the air ducts will get dirty over time and should be cleaned from time to time. As long as cleaning is done properly, there is no evidence to suggest that such cleaning is harmful.
The EPA recommends that if you have a furnace, stove, or fireplace that burns fuel, they be inspected for proper functioning and maintained before each heating season to protect against carbon monoxide poisoning. If you decide to clean your heating and cooling system, it's important to make sure that the service provider agrees to clean all components of the system and is qualified to do so. In addition, the service provider may 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 thoroughly investigated and you should be fully informed before deciding to allow the use of biocides or chemical treatments in your air ducts. They should only be applied, if at all, after the system has been properly cleaned of all visible dust or debris. Knowledge about cleaning air ducts is in its early stages, so no general recommendation can be offered as to whether you should clean your home's air ducts.
Pollutants that enter the home from both outdoor and indoor activities, such as cooking, cleaning, smoking, or just moving around can cause greater exposure to pollutants than dirty air ducts. On the other hand, if family members have unusual or unexplained symptoms or illnesses that you think might be related to your home environment, you should discuss this with your doctor. The EPA has published several publications for guidance on how to identify potential indoor air quality problems and ways to prevent or fix them. Whether you decide to clean your home's air ducts or not, preventing water and dirt from entering the system is the most effective way to avoid contamination (see How to Prevent Duct Contamination).If you think duct cleaning might be a good idea for your home but you're not sure, talk to a professional. The company that services your heating and cooling system can be a good source of advice.
You can also contact professional duct cleaning service providers and ask questions about their services.
