Bird Activity
Birds, primarily pigeons, roost on top of rooftop HVAC systems commonly found on commercial buildings. If the units offer shelter birds will often nest in that protected space.
Light to heavy
Why are birds there?
HVAC units are often on raised up platforms. The space under the platforms may be warm and dry making it an ideal place for nesting materials and a place birds feel safe.
HVAC Problems & Risks Caused by Birds
Bird feathers, bird droppings, and nesting material can contribute to clogging your HVAC’s evaporator coils. When the evaporator coils are plugged they can’t release heat which results in reduced airflow. Air filters can also become blocked and less efficient, reducing the quality of the air and posing a health hazard. In the event of a short circuit, the nesting materials used by birds is a fire hazard because they are highly combustable.
Considerations when Selecting Bird Control Products
Observe the birds at different times of the day, they may also be on ledges and the roof itself. If so, you have an opportunity to install bird spikes or other bird deterrent products to make the area and the AC units less attractive to birds.
Be Careful
Be careful not to damage or drill holes in the HVAC, it may void the warranty.
