Top 5 Benefits Of Air Duct Cleaning Banner


Inevitably, the air duct of your HVAC system will become contaminated with airborne pollutants. Eventually, these pollutants will accumulate inside the ducts and affect the air quality of your home. Included among the possible contaminants are pet dander, bacteria, carbon monoxide, and dust mites.


These pollutants flow throughout the space, triggering allergies and irritating respiratory conditions. They are especially harmful to children and the elderly. Below you will find the top 5 benefits of air duct cleaning:


  1. Safeguarding Against Illnesses


Family members afflicted with allergies can be adversely impacted by contaminated air ducts. As such, it is highly beneficial to create a healthy environment to prevent allergy triggers and keep other family members safe. The number of allergens can be considerably reduced through air duct cleaning.


  1. Lowering Energy Use


Experts have estimated that the removal of a mere 4/10 of an inch of pollutants from the coils of cooling systems can lower energy consumption by as much as 21%. This could significantly reduce your utility costs.


  1. Improving Air Quality


Air duct cleaning is vital to preserving healthy indoor air. The ducts are sometimes filled with rodent droppings, mildew, mold and other toxins. If the vents are not cleaned, these contaminants will ultimately be released into the living environment. Whether or not household members have allergies, they can potentially be afflicted with serious illnesses.


  1. Extending the Durability and Lifespan of the System


It has been estimated by experts that 90 percent of central heating and cooling systems breakdown or otherwise malfunction because of improper maintenance. It costs thousands of dollars to totally replace a HVAC system. Additionally, it is quite costly to pay for labor and replacement parts to repair the system.  Air duct cleaning can be incorporated into the regular maintenance routine of your system.


  1. Removing Unpleasant Odors


Unpleasant odors around the home could be an indication of the presence of dust, mildew or mold in the air ducts. Candles or air fresheners will not eliminate this odor. However, removing odors is among the remarkable benefits of air duct cleaning.


It is highly recommended by the National Air Duct Cleaners Association that your ducts should be cleaned every 3 to 5 years. However, other experts have suggested, depending on your particular situation, cleaning could be required every 2 to 5 years. The frequency of the cleaning will be contingent on factors like how often the system is used, where you are located and whether anyone in the home has asthma, allergies or other respiratory conditions.


The benefits of air duct cleaning include creating a healthier and happier environment for family members. This should be done, as recommended, to prevent the negative effects of a contaminated system.
