Pigeons Nesting in AC Outdoor Units and Duct Shafts

Pigeons use warm, sheltered shafts and AC enclosures.

The short answer

Nests can block airflow, damage units and cause fire risks, and droppings foul equipment. Install mesh, remove nests carefully, and have units checked. Seek professional help for shafts.

Risks

• Blocked airflow.
• Equipment damage.
• Droppings and mites.

Prevent

1. Fit mesh covers.
2. Remove nests humanely.
3. Clean and service units.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
