Jul 19, 2017I've never noticed any performance degradation with the AC after adding the window screen. There's not a ton of air being exchanged under the shroud really. If airflow is a concern then there are screens that advertise as better flowing. A lot of manufactures call them transparent or high visibility screens. The holes are made a little more precisely which allows more air to flow through them. Screens can get plugged up with dust and dirt after being up there for a while. Just hit them with the water hose to clean them off and keep the air flowing.
