The last thing you want to do is tap into a closed system, this is the beginning of the end in most cases. If a unit is damaged, the refrigerant will be gone anyways. A refrigerator holds 4 oz. to 5 oz. refrigerant, it takes a tiny leak to deplete it entirely.
Should you need to pump a system down then you can install a tap temporarily and sil floss in a proper suction line access, the high side is optional.

How do you install a compressor in a home ac unit?
This is not a job for the home fix-er-upper type. There are special tools required, and special training and Federal/EPA training and testing required for refrigerant recovering and recycling. Assuming, then, that you had all of this covered, you would: make the unit safe, disable and lockout the electrical power supply, Pull the refrigerant out of the system and store for later recycling, verify there is no pressure in the system, cut the pipes with a tube cutter leading to the compressor. Remove the power leads to the compressor. Remove the compressor. Mount the new compressor, Fit up new copper pipes and solder them in with a nitrogen purge and limited flux. Connect the power leads. Put a deep vacuum on the system and check for leaks. Charge the system with the correct number of pounds/ounces of refrigerant. Start the system and test run, checking the system pressures with guages to verify proper operation. Put all the panels back on, (with ALL the screws).
What precaution should be taken prior to recovering refrigerant from a chiller suspected of having tune leaks?

Where is the ac drain line on a ford f-150?
There isn't an "AC drain line". Refrigerant is recovered through the schrader valve on the high pressure side. Servicing an AC system is not a "do-it-yourself" task, especially when it comes to recovering, handling, and storing refrigerant.
