A method and apparatus for providing preconditioned air to a parked aircraft is disclosed. The apparatus includes a booster unit (10) adapted for association with an existing preconditioned air unit (12). The booster unit (10) includes an auxiliary compressor (112), an auxiliary evaporator (109) and an auxiliary condenser (100 and 100A). These auxiliary elements are interconnected by suitable conduit (114, 115, and 118) and an expansion valve (116). The booster unit (10) is associated with the preconditioned air unit (12) whereby the condenser fan(s) (82 and 84) of that unit is utilized to cool the condenser(s) (100 and 100A) of the booster unit (10). The method includes positioning the booster unit (10) in the air inlet of the preconditioned air unit (12); replacing either the condenser fan(s) (82 and 84) and/or the evaporator blower fan (38) of the preconditioned air unit (12) with a fan (38A or 82A and 84A) having a higher air flow rate capacity; and thereafter drawing air over the auxiliary condenser (100 and 100A) of the booster module (10) by means of the condenser fan (82 and 84 or 82A and 84A) of the preconditioned air unit (12), and also drawing air through the auxiliary evaporator (109) by operation of the P/C air blower fan (38) or (38A).
