Heating, ventilating and air-conditioning system for passenger compartments of motor vehicles mounted in hollow supports constituting the chassis of the vehicle, in which the heating agent or cooling agent is directed through pipes and structural elements of the vehicle towards heating air distribution openings, characterised in that independent heating modules are fixed to a first box structure (18), the structure of which is formed by the scuttle, which is connected to an air source (31) and in that delivery pipelines connected downstream of the said first box structure (18) consist of hollow longitudinal members (22, 22') which are constituent parts of the chassis (2), one of which receives a pipe (36) for the inlet of air taken from a second box structure formed between two parallel walls of the floor (20, 21) of the vehicle and containing a heating module assembly (30). <IMAGE>
