Air handler Kountry star 2006 spartan cummins 350

lots of air release sounds when moving. Excellerate or let off hissing sounds , brakes or air ride What is a air handler. at smooth constant speed no sounds. The sounds after startup when air brakes release one big burst, that is the sounds but for longer periods. Had coach for 6 months never released any air, should I drain tanks. How ? thanks book says auto release from tanks but I can see the pull lines in front at front tank in front of front tires
