It will sometimes seem strange 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 season. There are many potential causes of a frozen evaporator coil.
One prevalent cause is when poorly circulated air passes over the coil, forcing the temperature to drop below 32 degrees. The humidity on the coil freezes, resulting in a malfunctioning or completely defective air conditioner unit.
Frozen coils can also be a result of low refrigerant or Freon, or a dirty filter. You can do a visual inspection of the filter to learn whether it may be the source of the problem. If the filter is dirty, then it may be reducing 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?
Turn off the air conditioner and reach out to Precision Heating & Air at 321-452-3553 to request an appointment with a specialist!
Though the possibility of shutting off your AC during a heat wave can be less than ideal, it could ultimately save the evaporator coil. It may take as long as eight hours for the coil to be ice-free, so the faster the system is shut down, the earlier the problem can be removed. The fan can and should remain on to generate airflow. This also keeps your home as cool as possible, 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.
If you believe your system’s evaporator coil is frozen, call Precision Heating & Air at 321-452-3553 to arrange an appointment. We will direct a technician to inspect the unit as soon as we can.
