1. A method of servicing an air conditioning system in a motor vehicle, comprising:

suctioning existing inflammable coolant from the air conditioning system;

cleaning the air conditioning system after the suctioning; and

subsequently adding, using a filling system, replacement inflammable coolant to the air conditioning system;

wherein surrounding areas of the air conditioning system are ventilated such that air in the surrounding areas is suctioned out and discharged from the surrounding areas, wherein the surrounding areas include at least the locations of (i) an engine of the motor vehicle, and (ii) a housing for enclosing at least the filling system; and

wherein the vehicle is placed in a service space within the housing, the housing having a suction trough such that the suction trough is positioned directly below the engine of the motor vehicle, wherein the suction trough is connected to a ventilator via an air channel, and wherein air is suctioned out of the service space via the suction trough and the connected air channel by the ventilator.

2. The method according to claim 1 , wherein:

the housing is defined by a closed cabinet having (i) at least one air inlet to the interior of the cabinet, and (ii) a second ventilator connected with a hose; and

the air is suctioned out of the closed cabinet via the hose connected to the second ventilator.

3. The method according to claim 1 , wherein:

the housing is a closed cabinet;

and

the interior of the closed cabinet is ventilated by a ventilation system having at least one channel for removing air from the interior of the closed cabinet.

4. The method according to claim 3 , wherein:

during the servicing, a control of the tightness of the closed cabinet and the at least one channel is performed by subjecting the closed cabinet and the at least one channel to at least one of vacuum and pressure.
