PURPOSE: An apparatus and a method for preventing slugging noise of an air conditioner of a vehicle are provided to prevent slugging noise generated during initial driving of the air conditioner by allowing the slugging noise generated regardless of operation of a switch of the air conditioner to be absorbed by cranking noise generated during starting of the vehicle. CONSTITUTION: An apparatus comprises a TAFTRC2B(30) having forcible off processing time and two-dimensional map data by temperature of coolant set therein regardless of on of an air conditioner switch(31) after starting; the air conditioner switch allowing a driver to automatically/manually switch on/off the air conditioner; a coolant temperature part(32) sensing temperature of coolant at starting; a suction air temperature part(33) sensing temperature of air introduced from the outside at starting; a battery voltage part(34) sensing current voltage of a battery at starting; a crank switch part(35) sensing on/off state of a crank switch; an ECU(Electronic Control Unit:36) controlling signal inputted by the TAFTRC2B, the air conditioner switch, the coolant temperature part, the suction air temperature part, the battery voltage part and the crank switch part, and forcibly switching off a compressor relay(37) of an air conditioner; and the compressor relay switching on/off a compressor of the air conditioner depending on signal output from the ECU.
