You really need the vacuum machine that is used to suck out all the old stuff and moisture etc. to do it right.
Reclaim refrigerant. Be sure system is empty. Unhook refrigerant lines from condensor, and evap core. Best to use a "flush gun" and compressed air. Brake clean is a good solvent to use, as it evaporates quickly, and leaves no residue. Flush, and back flush. Use a clean container to capture the solvent as it comes out. Inspect to see if metal flakes are present. Usually one or two flushes in each direction will get all of the grayish, metal flakes out. Usually their is very little, if any in the evap core. On some Fords where compressor failure is catastrohic, and large amounts of metal are deposited in condensor--then maybe necessary to replace condensor. Especially on Rangers, and Explorers.
After flush complete. Then be sure and blow compressed air through the evap, and condensor core to remove residual solvent. Be sure and install the correct type, and amount of refrigerent oil in compressor and accumulator. Some techs will put a little oil in the evap & condensor too. My experience has shown that is not necessary. After system is evacutated and charged, check hi-side pressure with manifold gauge assbly to make sure their are no "pressure spikes", this could indicated a faulty condensor core.

How to install a Central Air Conditioning System?
Most new homes in the United States are built with central air conditioning systems installed during their construction. While many older homes do not have these systems, it is not difficult to install a central air conditioning system. The first step in installing a system is deciding which system is appropriate for the buyer’s needs. Central air conditioning systems typically consist of an outside unit which includes the condenser and compressor, an inside unit which contains the evaporator, and the ducts and pipes in the home that distribute the cold air to the different rooms in the building. Choosing which system is appropriate depends on the size of the area being cooled, the amount of power available to power the system, and the homeowner’s budget. Once the system has been chosen, the first step in installing the system is to install the ducts that will distribute the air inside the house. This is the most time-consuming part of the installation, and will take much longer than the actual installation of the unit. The typical homeowner will need to hire a contractor to install the ducts and central air unit, since installing a central air conditioning unit requires specialized knowledge in heating, ventilation, and air conditioning. It is also important to note that in many states, the person installing the central air conditioning system must be certified or accredited by the state in which the home is located. Another important note for the homeowner is that in many states, handling the refrigerants used in the air conditioning unit requires a special certification from the state. Once the ducts and vents have been installed, the next step in installing the central air conditioning system is to install the air handler unit. It is important to make sure the power is turned off to the house before the installation of the air handler unit is started. This component is typically installed in either the basement or attic of the house. Next install the compressor unit of the central air conditioning system. It is important to make sure the compressor is placed on a base which is level, and that the immediate area surrounding the compressor is empty. Once the compressor is installed and level, connect the compressor and air handler unit to the main power unit of the house. The final step of the installation is to install and connect the thermostat unit that will control the air conditioning unit. It is now time to turn power back on and check to make sure the unit is working properly. If the unit does not work properly, consult a licenced contractor for help in fixing any issues.
