Knowledge about cleaning air ducts is still in its infancy stage, that is why a blanket recommendation can’t be offered as to whether people should have their ducts in their houses cleaned. The United States Environmental Protection Agency or EPA urges people to read articles that provide valuable information about this topic to know the ins and outs of this business and its nature. 

It has never been actually helped prevent any health problems. Not only that, there are no conclusive studies that demonstrate that specks of dust and other particle levels in houses increase because of one dirty air duct. It is because most of the dirt lodges in them adhere to the duct surface and does not enter the living space.

People need to keep in mind that a dirty duct is only one of possible sources of dust and other particles present in every home. Pollutants that might enter houses both from indoor and outdoor activities like cooking, smoking, cleaning, or just moving around can cause exposure to harmful contaminants compared to dirty air ducts.

Moreover, there are no evidences that a small amount of dust or other particles in the ducts poses any serious risk to people’s health. Some studies suggest that cleaning, cooling and heating system parts like heat exchangers, fans, and coils might improve the system’s efficiency, resulting in a longer life for the structure, as well as some maintenance and energy cost savings. But little evidence available that cleaning the ducts can improve the system’s efficiency.

People may consider having their system cleaned because it is logical that it will get dirty after months of using and needs to be cleaned regularly. Provided that the structure is cleaned correctly, no evidence suggests cleaning would be damaging. Environmental Protection Agency doesn’t recommend that the system be cleaned regularly, but only if it is needed. 

However, Environmental Protection Agency recommends that if the house has a stove, fireplace, or a fuel-burning furnace, it needs to be inspected for properly serviced and functioning before every heating season to help protect against situations like carbon monoxide poisoning. 

If the client decides to have their systems cleaned, they need to take the same precautions; people usually would when assessing the reliability and competence of service providers. Cleaning service providers like air duct cleaning in Houston might tell homeowners that they need to apply different chemicals to the inside of the ducts as a way to kill fungi or mold and bacteria or germs. 

It helps prevent biological growth in the future. Service providers may also propose sealant applications to help prevent dirt and dust particles from being released inside the house, or to seal any air leaks. People should try to understand every pros and con of putting sealants or chemical biocides. 

While the use of sealants and chemical biocides may be suitable under certain circumstances, studies have not demonstrated the effectiveness in the ducts’ potential health effects and its cleaning process. According to the Environmental Protection Agency, there are no chemical biocides that are currently registered with their agency to be used in internally-insulated systems.

Air duct cleaning

A lot of people are now aware that air pollution inside the house is a severe problem of increased visibility and growing concerns. A lot of companies are marketing services and products intended to help improve the quality of air inside the house.

You have probably seen advertisements, received coupons inside the mall, or have been approached by companies directly, offering to clean your ducts as a way of improving the air quality inside your home. The service usually – but not always – cost from around $450 to $1,000 per cooling and heating system, depending on the services offered, system accessibility, the site of the duct system that needed to be cleaned, level of contamination, and climatic region. 

This job generally refers to the cleaning of different cooling and heating parts of forced air systems. That includes the diffusers and grilles, the registers and heat exchanger cooling and heating coiling coils, the return and supply ducts, condensate drip pans, fan motor, and housing, as well as air handling unit housing.

If not correctly installed, operated, and maintained, these parts may get contaminated with dust particles, pollen, and other forms of debris. Not only that, if moisture is present in the system, the potential for mold and other microbiological growth will increase exponentially. 

Spores from the growth may be released inside the house. Some of the contaminants can cause symptoms like allergic reactions in people if they are exposed to it. If you decide to have your cooling and heating structure adequately cleaned, it is crucial to ensure the company or service provider agrees to clean every nook and cranny in the system that can re-contaminate the entire duct system, thus nullifying potential advantages or benefits.
