Repair Your Frozen Air Conditioner with These 3 Simple Tips

Does the air emitting from your supply registers abruptly appear warm? Look at the indoor component of your air conditioner. This piece is located inside your furnace or air handler, if you have a heat pump. If there’s water seeping onto the floor, there could be ice on the evaporator coil. The AC coil within the system might have frozen 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 frost-free, All American Air Service Experts is here to help with air conditioning repair in Daytona Beach backed by a 100% satisfaction guarantee.*

Step 1: Switch the Air Conditioning Off and the Blower On

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

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

It can take under 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 underneath the AC unit. If the drain line is clogged, it might create a mess as the ice melts, possibly resulting in water damage.

Step 2: Troubleshoot the Problem

Low airflow is a primary explanation for an AC to become frozen. Here’s how to troubleshoot the situation:

  • Look at the filter. Insufficient airflow through a dirty filter could be the issue. Inspect and put in a new filter once a month or as soon as you see dust accumulation.
  • Open any shut supply vents. Your residence’s supply registers should remain open constantly. Shutting vents limits airflow over the evaporator coil, which can 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.
  • Not enough refrigerant: While airflow restrictions are the most frequent suspect, your air conditioning might also not have enough refrigerant. Depending on when it was replaced, it may use Freon®. Not enough refrigerant requires pro help from a certified HVAC specialist.

If inadequate airflow doesn’t seem to be the issue, then another issue is making your AC freeze up. If this is the case, simply thawing it out won’t take care of the trouble. The evaporator coil is likely to continually freeze unless you repair the root problem. Contact an HVAC technician to address troubles with your air conditioner, which could include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Insufficient refrigerant signals a leak somewhere. Only a specialist can pinpoint the leak, mend it, and recharge the system to the proper amount.
  • Grimy 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 may prevent airflow over the evaporator coil.
