It may seem unusual that evaporator coils can become frozen when the forecasted temperature is 95 degrees or more, but a frozen coil is a familiar issue during the hot summer days. There are several possible causes of a frozen evaporator coil.
One common cause is when restricted air passes over the coil, provoking the temperature to fall under 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 clogged filter. You can use a visual inspection of the filter to find out whether it may be the source of the problem. If the filter is dirty, then it might be limiting air flow; if it is wet, then water is collecting 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 contact Precision Heating & Air at 727-545-8731 to request an appointment with a specialist!
Though the act of shutting off your AC right in the middle of a heat wave can be less than ideal, it may ultimately spare the evaporator coil. It may take as long as eight hours for the coil to thaw out, so the earlier the system is turned off, the quicker the problem can be fixed. The fan can and should be left on to promote airflow. This also keeps your home cooler, and quickens the defrosting process. As the coil thaws, condensation will appear, so towels come in handy to soak up the water and minimize damage.
If you think your system’s evaporator coil may be frozen, call Precision Heating & Air at 727-545-8731 to schedule an appointment. We will direct a technician to examine the unit as soon as we can.
