If you noticed ice on your air conditioner, would you immediately take action? There are issues that you will immediately consider to be serious problems with your air conditioner. For example, if you notice it’s blowing hot air, that’s a clear sign your system isn’t working properly. Read more about that issue here: What To Do When There’s No Cool Air. Would you think the same thing if you noticed ice? After all, air conditioners are intended to keep things cool.

While this is true, your air conditioner should not be freezing anything, and ice on your air conditioner is a sign of trouble. Even though ice may not cause your system to break down entirely, serious problems can occur if you don’t figure out why your system is icing over. You can leave your air conditioning repairs in Bremerton, WA to our HVAC experts and enjoy a job done right.

Where does the ice come from?

To create ice, water is required. This confuses many homeowners since an air conditioning system does not use water to operate like a radiant heat system does. Although this is true, the air conditioner actually sources water from the air running through it.

More specifically, your evaporator coil is responsible for this water’s presence. During the cooling process, refrigerant is evaporated in the evaporator coil. That evaporation allows the air to be cooled since the refrigerant draws heat out of the air as it evaporates. This also dehumidifies the air. The moisture condensates on the evaporator coil, drips into a drip pan, and is removed from your property by the condensate drain line.

What causes the freezing?

Even with all this information, you still may be wondering how that condensation freezes. What causes this? There are a few possible answers. The first is a refrigerant leak, which is the most serious of all possible problems that cause this icing.

If your air conditioning system has a refrigerant leak, the evaporator coil will fail to absorb enough air from the system. When that happens, it will get so cold that it can cause the condensation on the coil to freeze. This further insulates the coil, which makes the problem even worse.

Another possible cause of ice is a very dirty air filter. Thankfully, this is a much simpler fix. In fact, you can change it yourself! A clogged air filter may be obstructing airflow so much that the system can’t pull enough heat from the air, and the result can look similar to a refrigerant leak.
