Air duct cleaning studies have shown that indoor air can be two to five times MORE polluted than outside air. This pollution comes from a variety of sources such as dirt, dust, pollen, mold spores, animal dander and other contaminants that are tracked into your carpeting and collect on your furniture.
Additionally, poorly maintained HVAC systems harbor mold, fungi, bacteria, pollen, dust mites and other disease-carrying biological pollutants which are re-circulated through forced air systems. Given the right conditions of moisture and temperature, these contaminants can flourish in the ductwork and be carried into your home or workspace, exposing your family or coworkers.
When HVAC systems are contaminated with dust, mold, construction debris, bacteria, or insulation fibers the indoor air quality of the facility suffers, putting residents at a higher risk for allergy and breathing problems in any home, and damaging employee productivity for businesses. When the contaminants are combined with varying temperatures, humidity levels, and airflow in the HVAC system the indoor air quality can dramatically deteriorate. Not only are there additional health risks with a dirty HVAC system, but a system’s operating and efficacy standards are impaired, resulting in higher operating cost for the facility.
Considerations that may warrant frequent cleaning:
– Smokers in the household.
– Pets that shed high amounts of hair and dander.
– Water contamination or damage to the home or HVAC system.
– Residents with allergies or asthma who might benefit from a reduction in the amount of indoor air pollutants in the HVAC system.
– Recent home renovations or remodeling that may have dirtied your air ducts.
