3 Simple Ways to Restore a Frozen Air Conditioner

Does the air emitting from your supply registers suddenly feel not cold enough? Check the indoor portion of your air conditioner. This component is located in your furnace or air handler, if you have a heat pump. If there’s water seeping onto the floor, there may be frost on the evaporator coil. The AC coil within the unit 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 back to normal, Service Experts Heating & Air Conditioning is here to help with air conditioning repair in Fort Lauderdale upheld by a 100% satisfaction guarantee.*

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

To begin—switch the thermostat from “cool” to “off.” This stops cold refrigerant from flowing to the outdoor compressor, which could hurt it and cause a pricey repair.

After that, adjust the fan from “auto” to “on.” This produces heated airflow over the frosty coils to help them thaw faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.

It may take less than an hour or most of the day for the ice to defrost, depending on the degree of the ice. While you’re waiting, watch the condensate pan under the AC unit. If the drain line is clogged, it can cause a mess as the ice melts, potentially resulting in water damage.

Step 2: Diagnose the Issue

Not enough airflow is a prime explanation for an AC to frost over. Here’s how to figure out the issue:

  • Exmaine the filter. Low airflow through a dirty filter could be the culprit. Look at and change the filter each month or immediately when you see dust buildup.
  • Open any shut supply vents. Your residence’s supply registers should stay open constantly. Shutting vents decreases airflow over the evaporator coil, which may result in it freezing.
  • Be on the lookout for obstructed return vents. These typically don’t have shiftable louvers, but furniture, rugs or curtains can still block them.
  • Not enough refrigerant: While airflow restrictions are the most typical cause, your air conditioner could also have insufficient refrigerant. Depending on when it was installed, it may have Freon® or Puron®. Low refrigerant requires pro assistance from a certified HVAC tech.

If low airflow doesn’t appear to be the trouble, then another issue is making your AC freeze up. If this is the case, merely defrosting it won’t fix the issue. The evaporator coil will possibly continually freeze unless you fix the main issue. Contact an HVAC technician to check for issues with your air conditioner, which might include:

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run low. Not enough refrigerant is a sign of a leak somewhere. Only a specialist can locate the leak, mend it, and recharge the system to the proper level.
  • Filthy evaporator coil: If dirt builds up on the coil, air can’t get to it, and it’s liable to freeze.
  • Broken blower: A broken motor or unbalanced fan can prevent airflow over the evaporator coil.
