Importance of Air Duct Cleaning

With time, a variety of pollutants can build up in air ducts, reducing indoor air quality and perhaps harming health. Frequent air duct cleaning keeps the interior atmosphere cleaner and stops the spread of dangerous particles by successfully eliminating dust, grime, mold, pet dander, and allergies. Reducing symptoms and fostering improved respiratory health greatly enhances the quality of the air, helping those with respiratory disorders like allergies or asthma.

Clean ducts also improve airflow, which makes your HVAC system work more effectively and uses less energy and money on utilities. As a vital component of house maintenance, air duct cleaning lessens the load on the system and increases its lifespan by avoiding early wear and potential malfunctions.

What Is Hiding in Your Ducts?

You must comprehend which pollutants are influencing the quality of the indoor air before moving on to the solutions. Numerous issues might arise for you and your family as a result of them, including seasonal allergies and an increased chance of respiratory illnesses. The most typical pollutants found in the air are listed below: 

  • Dust & Dirt: These are tiny particles that accumulate from everyday activities and outdoor elements, accumulate in the air ducts over time, and cling to the internal walls of the ductwork. These degrade the indoor air quality when circulated through your HVAC system throughout your home, settling on furniture, floors, and other surfaces. 
  • Pet Dander: Small pieces of skin that are shed by hairy or feathered animals, such as dogs, cats, rats, birds, and mice, compose pet dander. Sensitive people may have allergic reactions and breathing problems in response to pet dander. 
  • Pollen: Plants produce pollen, a fine powder that can get into your house through open windows, doors, clothes, and pets. Seasonal allergies brought on by pollen can produce symptoms including runny nose, itchy eyes, and throat, as well as sneezing. 
  • Mold & Mildew: Mold and mildew are fungi that thrive in damp, humid environments and are often found in air ducts that have accumulated moisture. They release spores into the air, which can cause respiratory problems and other health concerns. 
  • Chemical Residues: Chemicals used in and around your home, such as paints, insecticides, and cleaning supplies, can leave behind chemical residues. These residues can release volatile organic compounds (VOCs) into the air, which can cause headaches, dizziness, breathing difficulty, and other health problems. 

Effect on Health of Harmful Contaminants

This article concentrates on the negative features of indoor air quality, as they have a direct impact on human health. The risks associated with duct pollution are many, especially for individuals with allergies and breathing issues like asthma. The following are the effects on health that are linked to each kind of contaminant:

  • Allergies & Respiratory Issues: Dust and pollen are the cause of allergies and respiratory disorders, which is why symptoms like coughing, sneezing, and throat irritation arise.
  • Asthma: Apart from asthmatic bronchitis, mold spores are also accountable for various respiratory disorders that result in long-term sickness.
  • Infections: Aerosolized forms of infectious organisms, such as bacteria and viruses, can occur. They may also infiltrate the HVAC system in healthcare facilities, raising the risk of respiratory illnesses.
  • Chemical Sensitivities: People who are sensitive to these carcinogenic chemical residues may occasionally experience associated symptoms, including headaches and dizziness.

How Often Air Ducts Should Be Cleaned

Air ducts, like any other HVAC system, require regular cleaning to ensure maximum efficiency. The National Air Duct Cleaner Association (NADCA) recommends air duct cleaning every three to five years. This can be more immediate, depending on the condition of the duct. For instance, food manufacturers need duct cleaning services on a quarterly basis, whereas hospitals need air duct cleaning services on a much more regular basis because they are concerned about any kind of particulate that might pose a health risk to patients.
