Seller is taking things from house that's under contract.

[Al Mcbee]

We are about to close on a SFR in about a week or so, and they are in the process of moving all of their things out of the property. Sometimes, I'll drive by to check on their progress from time to time.

Now, here is the problem, and I'm not sure how to approach this with her. But the other day, I drove by and noticed that the a/c condensing unit that sits outside the house is missing. I asked the owner if she knew what happened to it, and she said maybe someone had picked it up, thinking it was junk because it wasn't hooked up yet. It was on the concrete pad next to the house ready for install, HELLO!

Now, I discovered that the kitchen refrigerator and window a/c is now missing as well. The fridge, and the window a/c were both written in as part of the deal as well as some other items. but I didn't think I had to write in the condensing unit as part of the contract, just figured it would be implied.  

Do I have any recourse? I am not sure what I should do at this point, I have never had this happen before. My head is spinning, I could really use some help from the BP nation.

Thanks everyone!
