What to Do If Your AC Line Is Frozen


Make Sure All Supply and Return Air Vents Are Open


If you notice problems with airflow, the first thing you should do is check your supply and return vents. Supply vents distribute clean, conditioned air throughout your home. As this air becomes stale, it’s pulled into the return vent, where it’s reconditioned before being sent back out through the supply vent.



When these vents are closed, air won’t flow in the home. Before examining your AC, check the vents in every room and ensure they’re all open.


Check for a Dirty Air Filter


Another possible cause of limited airflow is a dirty air filter. Your air conditioner’s filters catch elements you don’t want to breathe in, such as dirt and dust. Over time, filters can become clogged, ultimately blocking air from flowing in and out. The lack of airflow can then cause the entire coil to freeze and will completely restrict any air from moving through it. The AC may need to be powered off for one to two days to allow the coil to thaw after replacing the filter to allow proper functioning of the unit. This debris can also accumulate on your AC’s evaporator coil, requiring a more serious repair. In general, air filters should be cleaned regularly (about every two weeks).


Assess Your Outdoor Unit


In addition to checking your AC, assessing the outdoor unit is a good idea. Also known as the condensing unit, it works with your interior unit to release heat outside. An issue with the outdoor unit can result in rising internal temperatures.


Overgrown Shrubs or Clogged Leaves


From leaves and twigs to shrubs and debris, there’s no shortage of outdoor elements that can accumulate around your condensing unit. When these elements get lodged inside the unit, they can block airflow. Fortunately, removing the blockage can solve the problem.


Sounds of a Broken Fan


Shrubs and leaves aren’t the only things that can impede your outdoor unit’s airflow. If the fan is broken, the unit won’t be able to properly get rid of heat — which means the internal temperature won’t go down. First, make sure the fan is spinning. If it is, check for the following sounds of a broken fan:


  • Buzzing


  • Rattling


  • Screeching


  • Hissing


  • Clicking


  • Preventative Measures


    Nobody wants to deal with a frozen AC line. In addition to causing problems with your air conditioner, they require professional repairs. On the bright side, there are preventative measures you can take to help ensure this issue doesn’t arise in the first place.
