Hi, a rental house we own was a victim of a stolen ac (outside unit) and copper lines. Neighbor 4 doors down had the same thing happen last week. Cops said its a growing problem now that copper and aluminum is at all time high. So what can be done about this? Anything? Anyway to secure the outside unit to make it semi steal proof? This really pisses me off! To think some swine actually stole my ac unit really gets me.
