Rotobrush: Time to check school buildings' ductwork
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.
