If you have a car with an air conditioning system, it’s important to know how to evacuate the AC system without using the pump. This will help avoid any damage to the AC unit or your car. To evacuate the AC system without using the pump, first remove all of the screws that hold the unit together. Then disconnect all of the wires that run from the compressor to the AC unit. Finally, disconnect all of the cables that go from the AC unit to your car. Once these steps are complete, you’ll need to place a bucket over one end of a hose and pour water into it until it reaches a full stop. Then use your hand to push and pull on one end of the hose until all of the water has been used. Be sure not to damage any parts of your car while doing this!
