Freezing Evaporator Fun Facts & Frippery

<p >In this episode, Bryan and Sam discuss freezing evaporator coils. They explain why frozen coils happen and how to address them.</p> <p>When the coil's surface temperature drops below freezing (32 degrees), the moisture in the air that condenses on the coil can freeze to the coil. In those situations, your suction saturation will probably be in the mid to high twenties.</p> <p>Generally, freezing evaporators will occur when you have less load on the evaporator. When there is less heat, the evaporator temperature will drop accordingly. The return air temperature is usually around 35 degrees, though that number...
