A heating ventilation and air conditioning actuator device 12 comprises an actuator housing 18 and a motor housing 20 integrally formed as one-piece with an actuator wall 24 of the actuator housing. The motor may include a stator 32 abutable with the actuator wall, and a rotor 34 receivable therein, a drive shaft 26 being rotatable by the rotor and extending through the actuator wall into an interior of the actuator housing. The actuator housing may include a bearing 36 provided on a further actuator wall 38 opposing the first actuator wall. The bearing supports the drive shaft to prevent or limit deformation of the drive shaft. A HVAC unit comprises at least one said HVAC actuator device, at least one lever mechanism drivable by the HVAC actuator device, and one or more flaps pivotable by the lever mechanism when actuated by the HVAC actuator device. The HVAC unit may be included in a vehicle.
