How to Clean Your AC System Without Using a Vacuum Pump
Vacuuming an AC system without a pump is not recommended as it requires a vacuum pump to effectively remove all the air and moisture from the system. However, if you need to evacuate the system without a pump, you can use a refrigerant recovery machine that has a built-in vacuum pump. Simply connect the recovery machine to the AC system and run it until the pressure gauge shows that the system has been vacuumed. It is important to note that this method may not be as efficient as using a dedicated vacuum pump and may leave some air and moisture in the system.
