It can seem unusual that evaporator coils can become frozen when the forecasted temperature is 95 degrees or higher, but a frozen coil is a common issue during the hot summer season. There are multiple likely causes of a frozen evaporator coil.
One prevalent cause is when poorly circulated air passes near the coil, provoking the temperature to dip below 32 degrees. The condensation on the coil freezes, resulting in an inefficient or completely defective air conditioner unit.
Frozen coils can also be caused by low refrigerant or Freon, or a dirty filter. You can do a visual inspection of the filter to learn whether it may be the culprit. If the filter is dirty, then it might be affecting air flow; if it is wet, then water is condensing on the coil and missing the drain pan.
What Should You Do If You Have a Frozen Evaporator Coil?

Though the prospect of switching off your AC while you’re experiencing a heat wave can be intimidating, it might ultimately save the evaporator coil. It might take as long as eight hours for the coil to thaw, so the quicker the system is turned off, the faster the problem can be repaired. The fan can and should stay on to promote airflow. This also keeps your home as cool as possible, and quickens the defrosting process. As the coil thaws, condensation will show up, so towels will be useful to soak up the water and prevent damage.
