Why Is There Ice on My Air Conditioner?

Why Is There Ice on My Air Conditioner?

The image of ice on your air conditioner in South Florida might seem like an optical illusion, but this is actually a common issue related either to system malfunctions or inadequate maintenance. Fortunately, most instances of frozen evaporator coils can be handled promptly with little hassle. The following are some possible scenarios that may explain the polar conditions in your air handler.

Air Movement

The movement of refrigerant into your air handler occurs in tandem with pressure changes that allow the material to become extremely cold. The refrigerant then absorbs heat from the air in this space, which will cause the air to cool. The system’s fan moves the air out of this area to cool the house, but any condition that impedes the movement of air can lead to the coils remaining cold enough to promote ice formation. A broken fan is one possible explanation of ice, and poor airflow at the vents might confirm this situation. However, dirty evaporator coils or a dirty air filter can also restrict air movement in the handler.

Refrigerant Supplies and Lines

A refrigerant problem can also lead to lower temperatures in the air handler. This may be due to a refrigerant leak, which can affect the pressure levels and upset the system’s balance. There could also be a problem with kinks or blockages in these lines. These issues must be addressed through professional evaluation and repair.

Preliminary Troubleshooting

If you notice ice on your evaporator coils, you can make a filter change if the existing unit is dirty. You can also check for grime on the coils, which is reflective of the need for preventive maintenance. Dirty coils can add approximately 20 percent to your energy demands for air conditioning activity, so a tune-up is an excellent measure for protecting both your system and your budget. After you have changed the filter, allow the air conditioner to remain off until the ice has melted. If ice forms again with use, you will need to schedule a service call to identify the issue.
