Dirty HVAC systems lead to sick workers

August 12, 2010
WASHINGTON — AirQuest Environmental warns that tightly constructed buildings, recycled air and unmaintained heating, ventilating and air conditioning (HVAC) systems lead to sickness, according to a press release.
The recycled, circulated air in "tightly constructed" green buildings allow pathogens, bacteria, viruses and mold to build up and make employees in the building sick, the release stated.
"Indoor air quality is an increasing concern as people spend more time indoors than in the past," said Traci-Anne Boyle of AirQuest.
"Today''s tighter buildings are designed to reduce AC usage by keeping out hot and humid air. But that could mean less circulation of fresh air and a faster buildup of any indoor contaminants," Boyle added.
The issue is that many building managers do not regularly and adequately clean the air vents in the building, allowing bacteria to build, the release noted.
