Stove was dented, broken heating coil in oven, broken shelf bars in fridge, etc. 

Refrigerant isn't that valuable on newer units.I have had leaks that were hard to find, so up until you mentioned the tamper marks, I was thinking it was a leaky indoor coil.

I recently bought a house in plano.I had a done inspection and found that the Upstairs AC was not cooling.I reported this to my realtor and asked sellers to repair it.Sellers never repaired the issue completely (they just did quick fix by adding refrigerant) but upon further inspection found compressor was leaking and had coil issues.I followed up with my realtor multiple times to get it fixed from sellers she did not followed up consistently.Sellers realtor is saying she does'nt represent property as it is sold and closed.What are my options here shall i report them to TREC?

You will find motor & a couple of coils.

The master bedroom had coiled cable line in one corner under the carpet.  

For instance, the A/C inop, could be anything from a bad coil to a $15 contactor.
