the problem is more the turbulence it creates causing the air not to cross the coil as designed. there is a reason every manufacturers installation manuals say they must have 12 inches minimum of clearance all the way around .that means from fences,walls ,shrubs ,trash cans ,screens or anything else
What about all the turbulence created by the crap blocking airflow? I’ll keep spending 10 min a week clearing off the screen and skip the long tear downs to remove all that garbage.
Catches big cottonwood seeds and larger depths before it gets into the coils to plug up airflow. If cleared off frequently it prevents the big tear downs.
you obviously aren't understanding the issue. if you are an HVAC tech and advising your customers to put screens around their condenser then you should be prepared to pay to replace their compressor when it fails and the warranty is denied because of the screen the the installation instructions clearly say not to do
You are not understanding how air works.. Its a tiny mesh screen that does not in any way affect airflow.
I never said air won't go through a screen I said it won't flow across the coil as designed. your argument is invalid, so either you are arguing just to argue or you are truly an idiot
It absolutely affects the velocity and angle and time the air is contact with the coil surface
