How can I temporarily attach anti-bird spikes to a window air conditioner?

Is it safe to cover outside AC unit?

Outdoor cooling units are built to endure these harsh winter weather conditions, which eliminates the need for a cover. Moisture (water) can freeze the air conditioner’s condenser coils, which can cause damage over time. However, there is no way to keep moisture out 100% of the time.

What should I put around my air conditioner?

Consider decorative fencing, lattice, or a trellis to hide the AC unit. Not only can these landscaping elements allow airflow to the condenser, but they also prevent leaves and plant debris from collecting around the base of the unit.
