Vandalism at my old house? Or not?

Question

We recently moved and our old house is for sale, but we are in the process of cleaning it, etc.. But we do still own it. Our "yard man" lives down the street from our old house and still takes care of it/watches it while we are not there (he used to be a police chief). Yesterday he told my mom that 2 men were over there in the backyard up to no good. He asked them what business they had over there and they said "we were hired to do some work". My mom never hired them, and they refused to leave.. but he didn't call the cops b/c he didn't know. Today my mom went there to clean and the air conditioning didn't work right. There was a rumor going around that thieves are stealing copper from the ac units. Could this be what it is?

Answer 1

Yeah probably, My step dad owned a recycling plant and now when we see copper he collects it like it's gold.

So that is a good hypothesis  

Answer 2

You do still own it... The title would be in your name... the house is yours. More than likely the copper out of the AC unit is probably the cause of it not working.
