3 Fast Steps for Repairing a Frozen Air Conditioner

Does the air flowing from your supply registers suddenly appear warm? Check the indoor component of your air conditioner. This part is situated inside your furnace or air handler, if you use a heat pump. If there’s water seeping onto the floor, there might be crystals on the evaporator coil. The AC coil inside the equipment could have frosted over. You’ll need to thaw it before it can cool your residence again.

Here’s the things you should do. If you can’t get the coil defrosted, Teays Valley Service Experts is here to assist you with air conditioning repair in Hurricane that includes a a 100% satisfaction guarantee.*

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

First things first—switch the thermostat from “cool” to “off.” This stops chilly refrigerant from flowing to the outdoor compressor, which could damage it and lead to a pricey repair.

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

It might take not more than an hour or most of the day for the ice to melt, depending on the extent of the accumulation. While you’re waiting, watch the condensate pan under the AC unit. If the drain line is blocked, it may overflow as the ice melts, possibly causing water damage.

Step 2: Pinpoint the Issue

Low airflow is a chief explanation for an AC to frost over. Here’s how to troubleshoot the problem:

  • Exmaine the filter. Insufficient airflow through a dusty filter could be the issue. Check and replace the filter each month or once you see dust buildup.
  • Open any sealed supply vents. Your house’s supply registers should remain open all the time. Shutting vents reduces airflow over the evaporator coil, which may result in it freezing.
  • Be on the lookout for covered return vents. These usually don’t have moveable louvers, but furniture, rugs or curtains can still cover them.
  • Insufficient refrigerant: While airflow restrictions are the most common suspect, your system could also have insufficient refrigerant. Depending on when it was replaced, it may have Freon® or Puron®. Low refrigerant necessitates skilled help from a certified HVAC technician.

If poor airflow doesn’t feel like the trouble, then another problem is making your AC freeze up. If this is what’s happening, simply defrosting it won’t take care of the trouble. The evaporator coil will possibly continually freeze unless you fix the root cause. Call an HVAC professional to check for troubles with your air conditioner, which might include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t get used up. Low refrigerant indicates a leak somewhere. Only a specialist can locate the leak, mend it, and recharge the air conditioning to the correct amount.
  • Filthy evaporator coil: If grime collects on the coil, air can’t reach it, and it’s apt to freeze.
  • Nonfunctional blower: A defective motor or unbalanced fan may stop airflow over the evaporator coil.
