So, you're wondering how an air conditioning flush is performed? It's a multi-step process that involves evacuating the system, removing contaminants, and reintroducing refrigerant.

First, a technician will connect the manifold gauges to the proper fittings and use a specialized machine to reduce the pressure in the system to 0 psi. This is a crucial step to prevent any damage to the system.

Next, the technician will remove the refrigerant hose from both the high and low sides of the condenser and pour fresh fluid into the high-side inlet. Compressed air will then be added to the high side, forcing dirty fluid from the outlet hole in the condenser.

Some condensers have internal tubing that can't be flushed, so they need to be replaced. This is a common issue that can be avoided by regular maintenance.

The technician will then remove the mounting bracket that secures the accumulator and orifice tube/expansion valve. They'll visually inspect the orifice tube/expansion valve for any debris or signs of damage and replace it as necessary.

A new accumulator and orifice/expansion valve will be secured to the mounting bracket, ensuring the system is properly reassembled.

Finally, the technician will reintroduce refrigerant into the system, recharge it to the acceptable specification, and run the air conditioner for about 10 minutes to circulate the refrigerant throughout the system.
