It can seem unusual that evaporator coils can become frozen when the outdoor temperature is 95 degrees or higher, but a frozen coil is a frequent issue during the hot summer months. There are multiple potential causes of a frozen evaporator coil.
One prevalent cause is when restricted air passes near the coil, causing the temperature to dip below 32 degrees. The humidity on the coil freezes, and then you end up with a damaged or completely inoperative air conditioner unit.
Frozen coils can also be a result of low refrigerant or Freon, or a used filter. You can perform a visual inspection of the filter to find out whether it may be the culprit. If the filter is dirty, then it could be affecting air flow; if it is wet, then water is condensing on the coil and missing the drain pan.

Though the possibility of turning off your AC while you’re experiencing a heat wave can be intimidating, it could ultimately protect the evaporator coil. It might take as long as eight hours for the coil to thaw out, so the faster the system is turned off, the quicker the problem can be removed. The fan can and should be kept on to promote airflow. This also keeps your home cooler, and speeds up the defrosting process. As the coil thaws, condensation will be created, so towels are necessary to soak up the water and avoid damage.
