Why Is There Ice on My Air Conditioning System?

If you notice that there is ice on your air conditioning system, on the outdoor unit, the evaporator coil, or the refrigerant lines in particular, you may think that your system is just cooling things down exceptionally well. In truth, though, ice on one’s air conditioning system is always a sign of trouble, and of potentially serious problems with one’s home cooling system. If you notice ice on your air conditioner, or if you see water dripping that may be resulting from the melting of ice, let us know right away. The longer that the root cause of the problem goes unresolved, the greater the risk to your air conditioner in Des Moines, IA.

Dirty Filters

Chances are that you have heard our technicians speak to the importance of changing your air filter, if you have worked with us in the past. It bears repeating, though. Changing the air filer in your HVAC system is an absolute necessity. If you fail to do so on a regular basis, you are putting the efficiency of your system, as well as your indoor air quality, at risk. However, you may not realize that a dirty air filter can also lead to the problem of an iced-over evaporator coil. It is within the evaporator coil that refrigerant evaporates as it absorbs heat from the air passing over it. If your filter is dirty and reducing airflow, there may not be enough hot air passing over the coil, which can lead to icing.

Refrigerant Leaks

Another potential cause of ice on your air conditioner is a refrigerant leak. All air conditioners require a precise level of refrigerant in order to function properly. If your air conditioner is leaking refrigerant, it may not have enough to absorb heat properly, leading to the icing of the coil or of the refrigerant lines themselves. This can eventually cause serious problems to the compressor, so be sure to schedule AC repairs at the first sign of trouble.
