Today's energy-efficient homes are designed to be as airtight as possible, making them surprisingly good at trapping airborne dust, mold, pollen, and insect remains inside. The EPA reports that indoor air quality is four to five times more polluted than outdoor air, ranking indoor air pollution among the top five environmental risks to public health. As the main environment for contaminants lies within a home or business's HVAC unit and ductwork, the solution is a simple one ? clean the HVAC system. Unfortunately, that's not an easy task, as it requires the right technology, methods, and workmanship. This is the service that DUCTZ Duct Cleaning specializes in as indoor air quality professionals.
