Part 3: HVAC Technicians Best Option to Diagnose IAQ Problems
By Thomas A. Westerkamp
December 2012 -
HVAC technicians are the leading candidates for detecting, diagnosing and remediating IAQ problems in institutional and commercial facilities because HVAC systems form the first line of defense. Frequent air changes, combined with a proper mix of recirculated and outdoor air, optimize IAQ consistent with energy conservation.
IAQ-trained HVAC technicians can look for problems while performing routine preventive maintenance on HVAC systems, ensuring system components — including fans, motors, intake louvers, variable-air-volume controls, filters, and ducts — are clean and operate properly.
