3 Fast Ways to Restore a Frozen Air Conditioner

Does the air flowing from your supply registers unexpectedly appear warm? Check the indoor portion of your air conditioner. This component is located in your furnace or air handler, if you use a heat pump. If there’s water dripping onto the floor, there could be frost on the evaporator coil. The AC coil inside the unit could have frosted over. You’ll need to thaw it before it can cool your house again.

Here’s what to do. If you can’t get the coil frost-free, Air Engineers Service Experts is here to help with air conditioning repair in Jacksonville upheld by a 100% satisfaction guarantee.*

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

To begin—move the thermostat from “cool” to “off.” This prevents cold refrigerant from flowing to the outdoor compressor, which could harm it and lead to a costly repair.

After that, move the fan from “auto” to “on.” This creates warm airflow over the frosty coils to make them defrost faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.

It can take less than an hour or the majority of the day for the ice to defrost, depending on the level of the ice. While you’re waiting, watch the condensate pan under the AC unit. If the drain line is clogged, it can spill over as the ice melts, potentially creating water damage.

Step 2: Diagnose the Trouble

Bad airflow is a leading reason for an AC to become frozen. Here’s how to troubleshoot the problem:

  • Check the filter. Inadequate airflow through a dusty filter could be to blame. Check and put in a new filter each month or immediately when you observe dust accumulation.
  • Open any sealed supply vents. Your residence’s supply registers should remain open always. Sealing vents reduces airflow over the evaporator coil, which may result in it freezing.
  • Be on the lookout for obstructed return vents. These usually don’t come with moveable louvers, but furniture, rugs or curtains can still block them.
  • Low refrigerant: While airflow restrictions are the most common culprit, your air conditioning may also not have enough refrigerant. Depending on when it was replaced, it may have Freon®. Not enough refrigerant necessitates skilled attention from a certified HVAC specialist. H2: Step 3: Call an HVAC Expert at Air Engineers Service Experts

If poor airflow doesn’t appear to be the problem, then another problem is causing your AC frost over. If this is what’s going on, merely defrosting it won’t fix the issue. The evaporator coil will possibly keep freezing unless you fix the root issue. Call an HVAC specialist to look for issues with your air conditioner, which may include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run out. Low refrigerant means there’s a leak somewhere. Only a technician can find the leak, mend it, and recharge the air conditioner to the appropriate level.
  • Grimy evaporator coil: If dust accumulates on the coil, air can’t flow over it, and it’s apt to freeze.
  • Nonfunctional blower: A defective motor or unbalanced fan can stop airflow over the evaporator coil.
