They might be stealing them to sell for scrap metal.

Finance oil, gas, metals, minerals, health, technology, space and aviation with our 3rd fund.

One little blip with change in their job or business and they are toast.Conversely if someone makes 700k to 1 million or more a year and wants a custom build Mercedes SUV Blue Metallic color then why not?.....

@Miriam De HaroSorry for this inconvience, but where I live a brand new AC install you're looking around 2-3k with the coil still installed.
