Why Is There Ice on My AC Unit? What to Do Before It Gets Worse

Seeing ice on your air conditioning unit can be surprising—especially when it’s blazing hot outside. But this issue is more common than you might think and can be a clear sign that your AC system needs attention. Whether it’s a dirty filter or something more serious, taking the right steps early can save you from major discomfort and expensive repairs. Watch our video here about this topic.

If Its Not to Late Here is a Quick Fix

Give your unit time to defrost completely. This can take several hours, but it’s essential for getting a clear look at what’s going on. Running your AC while frozen not only makes the problem worse—it can cause your system to shut down entirely.

Once the ice is gone, check your air filter. A dirty or clogged filter is one of the most common causes of freezing. When airflow is restricted, your system can’t breathe properly, and that drop in airflow can cause moisture to freeze on the coils. Replacing the filter is a simple fix that may solve the problem on its own.
