“How can there be ice on my air conditioner?” This is a very popular question every summer here at Four Seasons. Countless customers experience this phenomenon, and wonder how it is even possible for an air conditioner to turn into a block of ice during some of the hottest days of the year. There are three potential causes to your problem, and luckily, two of them can be solved without any assistance from the professionals. The third cause of the problem, however, is the most complicated and warrants a major repair or possibly even replacement of the home comfort system.
3 Causes and What You Can Do to Repair Your A/C
- Cause #1- Dirty Filter: Dirty filters restrict air flow into the system. A lack of air flow causes the Freon to over-cool the system leading to the formation of ice. Shut the system down, allow the ice to thaw, replace the filter, and restart your unit.
- Cause #2- Low Temperatures: Is the temperature outside lower than 60 degrees? If so, it is too cold to run your air conditioner. Again the coils will become too cold and begin to freeze. This can cause significant damage to the compressor, and the unit needs to be shut down immediately! Only run the air conditioner when the outdoor temperature is above 60. If the indoor temperature is higher than 60, open the windows or find other ways to cool the home until the outdoor temperature is high enough to run your cooling system.
- Cause #3- Low Refrigerant: When the refrigerant in your system is low or the unit is empty, running the compressor could turn it to a block of ice. Professional help is required in this situation. The technician will perform a leak check and potentially repair the leak in the coils. If the leak is beyond repair or the system is too old to warrant repair, replacement may be necessary. Repairing the leak or replacing the unit is the only way to prevent freezing from happening again and to restore comfort to the home.
