Clearing the Air For the Next School Year

As schools prepare to reopen, parents can find reassurance in the steps being taken to ensure cleaner indoor air. Regular inspection and cleaning of HVAC systems during summer maintenance can significantly improve air quality for students and staff.

Ducts can accumulate a variety of contaminants, including bacteria, dust, skin cells, mold, and chemicals. These pollutants recirculate throughout the building multiple times a day, leading to a major build-up in ductwork and system components. Many school buildings, some over 50 years old, operate with air exchange rates well below recommended levels, exacerbating the problem. Rodents and insects can also infest ductwork, further contaminating the air.

Poor indoor air quality can lead to serious health issues, particularly for individuals with respiratory conditions, asthma, or allergies. It is linked to increased risks of pneumonia, upper respiratory problems, irritated eyes and throat, headaches, dizziness, and fatigue, all of which can hinder a child's ability to concentrate on learning. Experts note associations between poor indoor air quality and absenteeism, respiratory symptoms, and difficulties with concentration and learning.

However, improvements in ventilation, filtration, and HVAC maintenance offer a solution. Systematic cleaning of HVAC systems has been shown to reduce fine and coarse particulate matter. Working with certified professionals, such as those from NADCA member companies, ensures that contaminants are effectively removed at the source, promoting healthier indoor environments for the upcoming school year.
