How To PROPERLY Flush and Recharge A Contaminated AC System. In this video we are going to take a look at what it takes to clean out a contaminated A/C system. The vehicle in this video had too much oil in the system causing the high side pressures in the system to be extremely high and the low side pressures to be extremely low. The vehicle in this video was actually venting pressure out the pressure relief because the high side pressure was so high due to the amount of oil in the system. The only way to ensure the proper amount of oil is in the system is to flush out all the old oil and add the correct amount.

Proper AC system flushing requires nearly complete disassembly of the ac system. Flushing solvent needs to be ran though all the lines and the evaporator until the flushing solvent comes out clear. Things that should not be flushed are the: Compressor, Condenser, Orifice Tube or Expansion Valve, any line with a muffler, and the Receiver Dryer/Accumulator.
