What causes a window air conditioner unit to freeze up?
The three main reasons why window air conditioners freeze up are insufficient airflow, not enough refrigerant and mechanical failures. When the mechanical components malfunction, this can lead to decreased temperature and pressure.
Why does my window unit air conditioner keep freezing over?
The most common cause of window air conditioners icing up is a lack of adequate air flow. Room air is drawn over the evaporator coils where it is cooled and then re-circulated back into the room. Insufficient air flow over the evaporator coils will cause them to become too cold.
How do I keep my window air conditioner from freezing up?
Wipe off the fan blades on the large fan at the rear of the unit. If the coil fins are badly bent, straighten them with a fin comb. Similarly, airflow can be blocked if the air filter through which the air circulates gets clogged with dust, dirt, or debris such as pet hair.

How do you unfreeze an air conditioner fast?
If the AC unit is blowing hot air, first try turning off your air conditioner but leaving the fan on so it can defrost the AC unit. The AC's indoor fan will blow warm air over your AC's frozen coils, helping the ice thaw faster. Also check for a dirty air filter, which could be causing air flow blockage.
Why does my window unit keep freezing up?
The most common cause of window air conditioners icing up is a lack of adequate air flow. Room air is drawn over the evaporator coils where it is cooled and then re-circulated back into the room. Insufficient air flow over the evaporator coils will cause them to become too cold.
How do I unfreeze my AC unit?
- First, turn your air conditioner off at the thermostat. - Then, change the fan setting from 'auto' to 'on. ' - The fan will slowly defrost the system. - Once your air conditioner is ice-free, you can turn it back on and reset the fan to auto (This may take an hour or more).
How To Fix A Window Air Conditioner That Freezes Up
How long does it take for AC to unfreeze?
Your AC blower motor pulls in warm air from inside your home, and blows it over the refrigerant coils that make up the evaporator. How long will it take for your AC unit to thaw? It can take up to an 1 hour or 24 hours to unfreeze your air conditioner.
Will turning on the heat unfreeze AC?
Turning the HVAC fan to ON will force it to blow warm air over any frozen coils—which will speed up the defrost process. Make sure it's actually set to ON and not to AUTO. Automatic settings cause the fan to cycle—starting and stopping over and over again. You want continuous, non-stop airflow over the frozen areas.
3 Most Common Reasons Why Your Air Conditioner Freezes Up
Why does my window AC freeze up at night?
This typically happens if the AC system was allowed to run without a filter or if the filter used was extremely dirty, too small for the system, or of poor quality. Air flow problems can also be caused by a faulty fan or closed or blocked ducts and vents.
What causes my window air conditioner to freeze up?
Ice buildup can occur if a window air conditioner is too large for the room it serves. An oversized AC often short-cycles, turning on and off frequently. This prevents the good air circulation that normally keeps moist air from condensing on the cooling coils and freezing up.
