3 Fast Ways to Repair a Frozen Air Conditioner

Does the air emitting from your supply registers suddenly appear warm? Check the indoor component of your air conditioner. This part is situated in your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there might be frost on the evaporator coil. The AC coil inside the system might have frozen 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 upheld by a 100% satisfaction guarantee.*

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

First things first—move the thermostat from “cool” to “off.” This halts 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 creates warm airflow over the crystallized coils to make them melt faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.

It might take under an hour or the majority of the day for the ice to melt, depending on the level of the accumulation. While you’re waiting, check the condensate pan under the AC unit. If the drain line is blocked, it may overflow as the ice melts, likely causing water damage.

Step 2: Diagnose the Issue

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

  • Exmaine the filter. Insufficient airflow through a dirty filter could be the issue. Check and put in a new filter monthly or immediately when you see dust buildup.
  • Open any shut supply vents. Your residence’s supply registers should remain open all the time. Sealing vents reduces airflow over the evaporator coil, which may result in it freezing.
  • Look for obstructed return vents. These often don’t have moveable louvers, but furniture, rugs or curtains can still obstruct them.
  • Not enough refrigerant: While airflow restrictions are the most common suspect, your system could also not have enough refrigerant. Depending on when it was replaced, it may have Freon®. Low refrigerant necessitates skilled help from a certified HVAC technician. H2: Step 3: Get in Touch with an HVAC Tech at Teays Valley Service Experts

If poor airflow doesn’t feel like the issue, then another issue 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 probably keep freezing unless you take care of the main cause. Call an HVAC technician to check for troubles with your air conditioner, which might include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Low refrigerant signals 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.
  • Broken blower: A faulty motor or unbalanced fan may halt airflow over the evaporator coil.
