Pleated HVAC Air Filter (MERV 8-11)
A heavily loaded air filter increases static pressure and reduces the Cubic Feet per Minute (CFM) of air passing over the evaporator coil. Without sufficient warm return air to transfer heat to the refrigerant, the coil temperature drops below 32°F, causing atmospheric moisture to flash-freeze. This ice eventually blocks the entire coil face, preventing cooling of the interior space.

Blower Motor Run Capacitor
A failed or out-of-tolerance run capacitor prevents the indoor blower motor from reaching its designed RPM. Reduced airflow across the heat exchanger fails to provide the necessary thermal load to boil off the liquid refrigerant. The resulting drop in evaporator pressure and temperature leads to rapid ice accumulation on the coil and suction lines.

Thermal Expansion Valve (TXV)
The TXV regulates refrigerant flow based on superheat; if the internal sensing bulb loses its charge or the internal needle becomes stuck in a restricted position, the evaporator becomes starved of refrigerant. This causes a localized drop in pressure and temperature at the beginning of the coil, leading to ice formation that gradually propagates across the entire assembly.
