More efficient airflow for more even comfort and a lower operating cost. Look at some of the registers or grills around your home or work area. Check for particles of black dirt or dust on them especially on the return air grills. The indoor air quality of a home or business may be so poor that health problems such as allergies, asthma and other breathing disorders can be magnified. Not only can this be a health concern, but it also leads to lost time and productivity in the work place .
Many people have allergic reactions to pollen, bacteria, dust mites and mold.
These particles, along with other invisible pollutants, settle in the air ducts and are re-circulated every time the furnace blower is operated. Cleaning and disinfecting your ductwork not only eliminates most contaminants but also can improve the efficiency of your air conditioner and furnace by improving air flow. This poses a major health risk to those who suffer from allergies, asthma, immune system deficiencies and other chronic illnesses, as well as to small children and the elderly. Medical studies have confirmed that some diseases, including Legionnaire' s Disease, originate in and are spread by contaminated ventilation systems. Doctors, particularly allergists, now commonly prescribe HVAC and air duct cleaning as a remedy for health problems related to indoor air quality.
