It is highly unlikely that A/C or air recirculating equipment will contribute to the spread of any of the many flu viruses that are around all of the time, for many years manufacturers have included 'black' components within the equipment, basically discretes in various shapes like small towers or discs that emit UV-C, thats why you dont see swathes of people who work in fully controlled ventilation offices off sick, a cruise ship because of the sheer numbers and restricted movement acts as an incubator for any flu virus thats around at the time and is a cause for concern as it will contain many people who have low immune systems and underlying pulmonary issues such as the elderly.
It's highly unlikely that there are UV generators in by far the vast majority of air handling plant in most buildings. Even in healthcare premises, there is more chance of having UV units in the water supply to humidifiers than acting in the air stream.
