You have one compressor and a "head" in each room.

I also understand ACV in regards to items like for example: Tree falls on 7.5 year old A/C compressor.

If the equipment is older than 10 years, I would say stop wasting money on repairs and get it replaced (you may be able to reuse the existing outside compressor it uses R410a refrigerant, but if its R22, it junk).The way they left it, it is not operational for either heat or cooling.Personally, I would review what you paid to the original HVAC company and see how they took advantage of you.

Had a A/C compressor failure and need a certified A/C tech to replace the compressor and coil.

The technician write up references that the exterior heat pump compressor had locked rotor amps and couldn't be evaluated and recommended a whole new system due to it using the old refrigerant and it's condition and that the drain pan was rusted. 

The best set up is the one with flexible hollow rods with special attachements powered by air compressor, that way less chance of dryer duct to get disconnected in the wall or ceiling.

Please tell me what you would do in my place instead.LAYOUT:There is a separate HVAC system for each condo, with the compressor outdoors and the air handler with the only return grille in the great room.The great room is long and skinny with 2 suites on each side, for 4 suites in all. 

That can damage the blower fan and can cause AC coils to freeze up, which could damage the compressor. 

Did they steal the outside compressor?

I had the oven repaired, AC compressor and condenser replaced, and heater control unit replaced.
