What should I do if a mouse gets into the air conditioner? - briefly

What should I do if a mouse gets into the air conditioner? - in detail
If a rodent has entered the air‑conditioning unit, immediate action prevents damage and health risks.
First, disconnect power at the circuit breaker to eliminate the chance of electrical shock or short‑circuiting while you work inside the appliance. Verify that the unit is completely offline before proceeding.
Next, open the access panels. Use a flashlight to locate the animal and any nesting material. If the mouse is alive, coax it toward an opening with a gentle push; avoid direct contact. If it is dead, remove the carcass with disposable gloves and place it in a sealed bag for disposal.
After extraction, inspect the interior for chewed wires, insulation, or droppings. Replace any damaged components—particularly wiring, insulation, and fan blades—to restore proper function. Clean all surfaces with a disinfectant safe for electronic equipment, then wipe the area with a damp cloth to remove residue.
Finally, seal entry points. Apply steel wool or copper mesh to gaps around the unit, and use silicone caulk to close cracks in the housing, ductwork, or surrounding walls. Install a fine mesh screen over the outdoor intake to block future intrusions. Schedule regular maintenance checks to detect signs of rodents early.
