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?

We went through an almost identical situation with Freddie Mac on a house where five bathrooms, the laundry room, the AC compressors, and a handful of walls were decimated by copper thieves.

I understand you aren't giving tax or legal advice, so the disclaimer is out there.I have some expenses that I need to take care of on some rental properties and wanted to see your thoughts if these fall under the categories of repairs (thus deductible) or if it was a capital improvement.A/C: I "repaired" the compressor earlier this year when it went out, total cost was $2,500 would this be an improvement or a repair?

You should always blow out all the water lines with a small compressor.
