Mud dauber screens

When you install ANY type Insect screen over the outside refer vent, you cut the air flow volume by about 50%. Big deal? Yes, when it gets over 70 degrees outside. Reduced fresh air flow over the refer Condenser coil will inhibit correct cooling. IF Insects make a nest on the refer burner it is easy to fix. Think about this when you decide to install the screens. Doug

Wouldn't the amount of air flow be dependent on the size of openings in the screen? I've done it for many years and have noticed no degradation in the cooling ability of my fridge. Having 2 cooling fans at the top of the vent may help offset any reduction in airflow ability.
