Why is my AC Freezing?

If your air conditioner stops working or it is no longer blowing cool air into the house, you may notice that the outside unit has frozen over. This freezing of your air conditioner is not uncommon however if it continues to happen, or is not fixed it may cause damage to your AC unit. If you notice ice around your AC system, it is best to call a professional right away. In the meantime, this article can help you get some basic answers to the question “why is my AC freezing?”.

Why is my AC freezing?

So while it may happen to many AC units it does not mean that your AC freezing is a good thing or even a normal problem that will fix itself. There are many things happening within your system that can result in your AC freezing.  Let’s look at some of the issues that may cause your AC to freeze.

  • If the air flow that runs across your air conditioner’s evaporator coil is blocked, partially or completely, this can cause the evaporator coil to freeze up.  This blockage will stop the Freon from doing its work and your air conditioner will freeze up.
  • If your system is low on Freon or is leaking Freon, this can be another reason why your air conditioner may freeze up.
  • Running your air conditioner when the air outside is below or around 62 degrees may also cause your air conditioner to freeze up. This is due to the fact that your system is designed to only function within a specific temperature range.
  • Another reason for your air conditioner freezing up is that there may be a mechanical failure. If your refrigerant line is blocked or has kinks, or a major part of your system like the blower fan is not running this can affect the pressure in your system, causing freezing to occur.
