Yes. A ducted heat pump removes moisture from the air whenever it runs in cooling mode. As air passes over the cold internal coil, moisture in the air condenses onto the coil surface and drains away through the drain pan and drain line, lowering humidity at the same time as temperature.Some systems also have a dedicated dry mode that prioritises moisture removal over cooling, useful during humid but mild weather when full cooling isn't needed.This moisture removal is also why the drain system matters so much for ducted systems. A blocked drain line or a dirty drain pan is one of the most common causes of smell and, left unaddressed, water damage to ceilings.
