Copper and aluminum theft from outdoor AC units is a real problem in parts of Miami-Dade, especially on vacant properties, rentals and businesses. A locking steel cage makes the condenser a much harder target.
AC condenser cage installation puts a locking steel enclosure around the outdoor unit, bolted to the pad, so thieves cannot easily cut lines or remove copper and aluminum. The cage is sized for airflow and service access, and it can be combined with hurricane tie-downs.

Thieves target condensers for their copper and aluminum. In a few minutes they can cut the line set and electrical whip, leaving the owner with a destroyed system and a large repair bill.
A properly built cage surrounds the condenser on all sides, bolts into the concrete pad and locks. It slows thieves down enough that most move on.
We size cages so the condenser still gets full airflow and technicians can still service it, and we can add hurricane tie-downs and surge protection on the same visit.

Local context
Condenser theft in Miami-Dade
Copper theft rises when metal prices climb, and condensers on vacant homes, rentals between tenants, churches and small businesses are frequent targets.
Ground-level units in alleys or behind buildings are easiest to hit. Rooftop units on commercial buildings are targeted too.
A cage, good lighting and a camera together make a property far less attractive to thieves.
