Repair Your Frozen Air Conditioner with These 3 Simple Tips

Does the air emitting from your supply registers unexpectedly appear warm? Look at the indoor part of your air conditioner. This component is located inside your furnace or air handler, if you have a heat pump. If there’s water seeping onto the floor, there might be ice on the evaporator coil. The AC coil within the system might have frosted over. You’ll need to defrost it before it can cool your home again.

Here’s the steps you should take. If you can’t get the coil back to normal, All American Air Service Experts is here to help with air conditioning repair in Daytona Beach backed by a 100% satisfaction guarantee.*

Step 1: Set the Air Conditioning to Off and the Blower On

First things first—set the thermostat from “cool” to “off.” This prevents chilly refrigerant from moving to the outdoor compressor, which could hurt it and result in a costly repair.

Then, move the fan from “auto” to “on.” This produces warm airflow over the crystallized coils to force them to thaw faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.

It can take not more than an hour or the majority of the day for the ice to thaw, depending on the amount of the ice. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is clogged, it might create a mess as the ice melts, likely creating water damage.

Step 2: Troubleshoot the Situation

Poor airflow is a primary explanation for an AC to frost over. Here’s how to troubleshoot the situation:

  • Look at the filter. Insufficient airflow through a dusty filter could be the issue. Inspect and put in a new filter once a month or as soon as you see dust buildup.
  • Open any shut supply vents. Your house’s supply registers should remain open constantly. Shutting vents limits airflow over the evaporator coil, which might cause it to freeze.
  • Check for blocked return vents. These often don’t use moveable louvers, but furniture, rugs or curtains can still obstruct them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent culprit, your air conditioner might also have insufficient refrigerant. Depending on when it was replaced, it may use Freon® or Puron®. Insufficient refrigerant requires skilled help from a certified HVAC tech.

If inadequate airflow doesn’t appear to be the issue, then another issue is making your AC freeze up. If this is the case, simply thawing it out won’t repair the problem. The evaporator coil is likely to continually freeze unless you repair the root problem. Contact an HVAC professional to look for troubles with your air conditioner, which may include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Insufficient refrigerant indicates a leak somewhere. Only a specialist can pinpoint the leak, repair it, and recharge the system to the proper concentration.
  • Filthy evaporator coil: If dust accumulates on the coil, air can’t get to it, and it’s apt to freeze.
  • Malfunctioning blower: A bad motor or unbalanced fan could prevent airflow over the evaporator coil.
