A zone motor is typically used in ducted residential or commercial air conditioning systems to control air flow to selected zones according to the room temperature selected on the control panel. It usually consists of flap operating inside the duct tube allowing air to be restricted according to the needs of that particular zone. Sometimes a particular room, further from the finned coil and blower fan of the cooling system, may require extra cooling such as a kitchen or another room perhaps subject to other heat loads. Consequently, additional cooling might adversely affect the comfort of other rooms in the house.

The purpose of the zone motor is to open and allow more cooling air flow to those rooms in need, while restricting air flow and lower temperatures to rooms less affected by additional heat loads. However, as with all mechanical systems, sometimes components break down needing attention or replacement and when this happens Local Air Conditioning Repairs technicians can diagnose the fault quickly, replace your zone motor if needed and restore normal operation quickly.
