It might seem odd that evaporator coils can freeze when the current temperature is 95 degrees or more, but a frozen coil is a frequent issue during the hot summer days. There are several likely causes of a frozen evaporator coil.
One prevailing cause is when restricted air passes over the coil, provoking the temperature to slip beneath 32 degrees. The moisture 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 clogged filter. You can use a visual inspection of the filter to determine whether it may be the cause. If the filter is dirty, then it may 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?
Turn off the AC and reach out to Precision Heating & Air at (407) 519-3265 to request an appointment with a specialist!
Though the act of shutting off your AC in the middle of a heat wave can be intimidating, it could ultimately save the evaporator coil. It can 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 addressed. The fan can and should be left on to generate airflow. This also keeps your home from getting too warm, and speeds up the defrosting process. As the coil thaws, condensation will show up, so towels are necessary to soak up the water and prevent damage.
If you think your system’s evaporator coil may be frozen, call Precision Heating & Air at (407) 519-3265 to arrange an appointment. We will send a technician to examine the unit right away.
