Microbiological growth within the HVAC system, duct work, drain pans, and air filters can go undetected for long periods, spread throughout the building, and cause serious illness or death (for example, through Legionnaire’s disease). When designing these systems, provide for easy access for inspection, cleaning, draining, and replacement in these areas.
