Why an Iced-Over AC Coil is Bad News

Sometimes people will see a build-up of ice on their air conditioner coil and think that it isn’t an issue. They may even think that it is a sign that their system is doing a really good job. Unfortunately, this isn’t the truth.

A build-up of ice on your AC system’s coil is a sign of a problem. It can be caused by more than one problem actually, all of which we will explain in a moment. The end result here is that it can and will harm your air conditioner if it is not fixed soon.

What Causes That Build-Up of Ice?

There is more than one underlying cause that can lead to ice building up on your air conditioner, specifically on your evaporator coil. Here are some of the issues that can lead to an iced-over evaporator coil:

  • A clogged air filter: Yes, too much dirt and debris can eventually cause major problems for your air conditioner. If the air filter that air passes through to enter your AC system is packed with dirt or dust, it will reduce the amount of air that is able to get to your evaporator coil to be cooled. This can mean that the air immediately around your coil simply gets colder and colder until it creates ice.
  • A dirty evaporator coil: Yes we are back to dirt again, but that’s because it is a serious issue. If dirt and other debris are allowed to build-up on your evaporator coil, it will hinder the transfer of heat to your refrigerant. This will lead to the creation of ice on the coil as your system can’t absorb heat.
  • Low refrigerant levels: This is a bit problem in more ways than one but for now we want to focus on the icy implications it can have. Low refrigerant levels will, you guessed it, make it hard or impossible for your system to absorb heat and create cool air. Ultimately this will end up creating ice on the coil.
