With the 2013-2014 school year starting soon, a manufacturer of ductwork-cleaning equipment is reminding districts to consider the condition of their HVAC systems.

Citing U.S. Environmental Protection Agency studies, officials with Rotobrush International LLC say that schools commonly have indoor air pollution from mold, dust and other contaminants in ductwork and air-conditioning drip pans. A proper cleaning can fix many of the problems, Rotobrush said. 

“During the school year, our children spend a majority of the day in the classroom. It’s just as important to improve indoor air quality there as it is at home,” said Rotobrush President and CEO Lane Jeffryes. “Since 1980, the asthma death rate for children under 19 years old has increased by nearly 80 percent. Eliminating airborne triggers by proper ductwork cleaning and maintenance is a proactive step to creating a productive learning environment.”

Rotobrush and the EPA suggest cleaning supply diffusers, return registers and outside air intakes, inspecting and maintaining HVAC systems regularly, changing filters, checking that condensate pans drain, provide proper outside air ventilation and keeping ventilators clear of debris.
