It’s a bizarre, yet common sight. There you are in the middle of summer. The sun is beating down. Everyone is wearing shorts. And your outside air conditioner unit or heat pump is caked in solid ice. How is it possible for an air conditioner to look like an igloo, even in the warmest summer months? Needless to say, it is abnormal for ice to form on an air conditioner, and it is certainly cause for concern. Several common problems can cause air conditioner freeze-ups: The buildup of ice and frost is a sure sign that your air conditioner is not operating properly. If you notice a decline in your system’s cooling capacity, ice build-up should be the first thing you suspect. Air conditioner freeze-ups should be addressed immediately; continued ice accmulation can cause permanent damage to your a/c unit. The first thing you should do once you notice your air conditioner is frozen is to turn it off and let it defrost completely. Once it has defrosted, check the airflow. Clean or replace dirty filters or remove any visible dirt or obstructions;

in some cases, this could be all that is needed.

How did the leak start?; Nope – the air conditioning equipment may be frozen. But, Service Experts Heating & Air Conditioning offers hope. The evaporator coil is the component of a central A/C unit that actually freezes. This component of the air conditioner transfers (evaporates) heat from the inside to the outside of your your city area home. reasons why the evaporator coil may 1. Airflow restriction, or 2. the ending effect is that the air conditioner's evaporator coil cannot operate to properly transfer heat, and in essence 'overcools'The net effect of this super-cooling is condensation (that's water formation), and finally ice forms from that condensation as it cools below the freezing point. Yep, the A/C transformed into an old-school icebox.

Your outside air conditioning refrigerant line is covered in ice—which seems crazy in Arizona heat. Chances are, the indoor unit’s evaporator coil is frozen solid and cold liquid refrigerant is flowing to the outside unit through the refrigerant line (which is why it’s covered in ice).

This is an evaporator coil. DO THIS RIGHT NOW: Turn off your AC and turn the fan setting to “On.” This will unfreeze the evaporator coil and prevent any damage to the compressor (a very expensive part you don’t want to replace). Now, let’s delve into what can cause an evaporator coil to freeze up and what you can do to ensure this never happens again. What causes the evaporator coil to freeze up An evaporator coil, a group of copper tubes, freezes when the refrigerant flowing through the tubes gets too cold, causing the moisture in the surrounding air to freeze. So what causes the refrigerant to get too cold? Usually, it’s one of two things: Low airflow over the evaporator coil Low amounts of refrigerant What can cause these two problems? Let’s divide the possible causes into things you can solve right away and things you’ll need a technician to solve. Problems you can fix Clogged/dirty air filter—A dirty filter reduces airflow over the evaporator coil, causing it to freeze.

Check the filter at least once a month. Closed supply vents—Don’t close supply vents (the vents that blow air out)—even in unused rooms. Closing vents reduces airflow over the evaporator coil. Blocked return vents—Ensure that furniture or curtains aren’t blocking the return vents (the grates where air gets sucked in).  Like closing supply vents, this reduces airflow over the evaporator coil. Problems a technician needs to fix Refrigerant leak— The main cause of low refrigerant is a refrigerant leak. The technician needs to evacuate the remaining refrigerant, and then find and—if possible—fix the leak. Malfunctioning indoor blower— If the blower isn’t working properly, there may not be enough air blowing over the evaporator coil, causing it to freeze up. Dirty evaporator coil—Dirt blocks airflow over the evaporator coil, causing it to freeze up. Note: This list isn't exhaustive; it’s just a quick overview of common problems. Change the filter, and open and unblock any supply and return vents.
