When your AC unit is freezing up, something has altered your system that cools your evaporator coil more than it should, causing the unit to freeze up. Your air conditioning unit may be freezing up because: 

• Your AC unit has blocked or low air flow. 
• Your AC unit is being used too frequently.
• Your AC unit has broken parts. 
• Your AC unit is poorly maintained.
• Your AC unit has low refrigerant levels. 

This problem won’t go away and can damage your AC unit’s compressor. You should check your air filter to see if it is clogged or dirty. You may find the problem is simply due to a dirty filter, which can block over 60 percent of the air flow and stress your system. Replace the air filter or remove it and see if cooling returns. You should let the frozen refrigerant lines thaw first before using the AC. If the problem persists, you may need to have your AC unit repaired by an HVAC technician.
