It will sometimes seem unusual that evaporator coils can ice over when the current temperature is 95 degrees or hotter, but a frozen coil is a typical issue during the hot summer days. There are a number of possible causes of a frozen evaporator coil.
One prevalent cause is when restricted air passes above the coil, provoking the temperature to slip below 32 degrees. The condensation on the coil freezes, and then you end up with a malfunctioning or completely inactive air conditioner unit.
Frozen coils may also be a byproduct of low refrigerant or Freon, or a clogged filter. You can use a visual inspection of the filter to learn whether it may be the culprit. If the filter is dirty, then it might be reducing air flow; if it is wet, then water is collecting on the coil and missing the drain pan.

Though the prospect of shutting off your AC right in the middle of a heat wave can be less than ideal, it might ultimately save the evaporator coil. It can take as long as eight hours for the coil to be ice-free, so the earlier the system is shut down, the quicker the problem can be resolved. The fan can and should remain on to encourage airflow. This also keeps your home from getting too warm, and quickens the defrosting process. As the coil thaws, condensation will appear, so towels will be useful to soak up the water and prevent damage.
If you think your system’s evaporator coil might be frozen, call Precision Heating & Air at 407-774-9850 to schedule an appointment. We will assign a technician to inspect the unit as soon as we can.
