What Causes Truck AC to freeze up?
The problem of car AC lines freezing up is caused by moisture that has been introduced into the system. Generally, the only way that moisture can get into the AC is if the system is opened up or if you have a leak. If there is a leak, air and moisture can be pulled in by vacuum on the low side of the system.
What does it mean when your air conditioner freezes over?
Simply put, when your air conditioner suffers from poor airflow, the evaporator coil gets too cold. This is the part that “cools” the air and without good airflow, it freezes. If, however, there’s a lack of warm air moving across the evaporator coils, they ice over. The ice even travels along the refrigerant lines.
What do you do when your AC coils are frozen?
If your evaporator coil has frozen up, the first thing you should do is turn off your unit. Make sure to turn it off at the breaker box. If you continue to run the unit while the coil is frozen, it could cause extensive damage to the system.
