Commercial air duct sanitation services are advertised to the public as being effective in reducing indoor aeroallergen levels despite the absence of published supporting data.
Eight residential heat-ventilation-air conditioning (HVAC) systems in six homes arid seven HVAC systems in five homes in winter arid summer, respectively, were sampled to determine fungal colony forming units (CFUs) prior to arid after an HVAC sanitation procedure was performed by a local company.
Two houses in which no sanitation procedure was performed served as controls in each study phase.
Two sample sets were obtained at each HVAC system prior to cleaning in order to determine baseline CFU levels.
