I don’t intend to occupy the house as a primary residence but purchase the property as an investment property. 

(FWIW,$8K on just the compressor seem excessive.)Otherwise, unless your contract with your GC says they will provide 24/7 surveillance, or you can prove the AC was never installed, you own the problem.If the property has been vacant for more than 30 days, most policies won't cover vandalism unless you have added a Builders Risk Addendum.
