Air Conditioner Question - 95 Disco 1

Air Conditioner Question - 95 Disco 1
Ok - so I started a new thread, because my situation is kind of unique.
When I turn on my a/c unit - both fans come on. At first, the a/c clutch was not engaging. I bought a can of do it yourself a/c recharge - put in 1/2 a can and the clutch engages. Success!
Not blowing cold air still - after putting in the remainder of the can.
Also - still not registering any pressure on the gauge that came with the can.
Here is what makes my situation a bit unique. Someone redid the heads on my Rover before I bought it.
My questions are:
1) When they did this, wouldn't they have had to drain the system completely?
2) If so - how many cans should it take to recharge the system?
I emptied the entire can - it is still not blowing cold, and it is registering 0 on the gauge. I figure it is going to take a lot more, or my gauge is faulty.
Thanks for your help.

They may have laid compressor to the side with lines attached. Or the could have just vented to the atmosphere which is not good. Here are the economic facts: If one can has not done it, you have some other problems. The cost of a set of gauges and vac pump exceed the cost of a shop handling this. You might be able to rent gauges and vac pump, but if you have never used them then there is the learning curve.
You could have a problem with the drier needing to be replaced if compressor lines were off and system was exposed to open air. The drier soaks up humidity, and if you buy one they come shrink wrapped. Once you open the wrap it must be installed in minutes.
You tried the basic fix. Now it is time to spend a small fee and get it done, save money on other DIY things to make up the difference.
Full fill is 0.9 kilograms, with rear air that would jump to 1.15 kilograms of R134a.

Took it to the shop - they inspected it for free. Said I have a leak in the line that feeds the rear a/c. The shop specializes in a/c and driveline - but the guy wouldn't let me watch them work, and the kid using the vac system seemed to be fumbling with the machine a bit. The owner did go out and talk to him a couple times (I felt like he was teaching him how to use the machine).... Not sure that I trust them...but have nothing else to go on.
Is there a way for me to verify what they were diagnosed - or should I just take it to another shop?
If it is a leak to the rear - is replacing the lines, or bypassing the rear an option?
Thanks

Thanks - I will search for the threads on bypassing the rear air.
Just curios - if they didn't pump in the die to look for the leak, how would he know that there is a leak in the rear air.
I understand about the liability - but the whole thing just felt weird. He was secretive, and the kid didn't seem to know what he was doing - they were talking in hushed voices around me. It was just a weird vibe.

At this point - since I live in the state of Washington, and our summer is almost over - I'm not going to worry about it. I will look into this next spring, before our 75 + degree days kick in.
