3 Easy Ways to Fix a Frozen Air Conditioner

Does the air emitting from your supply registers unexpectedly appear warm? Look at the indoor part of your air conditioner. This component is situated inside your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there could be frost on the evaporator coil. The AC coil within the system may have frozen. 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 back to normal, Service Experts Heating & Air Conditioning is here to assist you with air conditioning repair in Shreveport that includes a a 100% satisfaction guarantee.*

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

To get started—move the thermostat from “cool” to “off.” This stops chilly refrigerant from flowing to the outdoor compressor, which could harm it and lead to an expensive repair.

Then, switch the fan from “auto” to “on.” This produces warm airflow over the frosty coils to help them defrost faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It may take not more than an hour or the better part of a day for the ice to melt, depending on the amount of the accumulation. While you’re waiting, check the condensate pan below the AC unit. If the drain line is obstructed, it can cause a mess as the ice melts, possibly creating water damage.

Step 2: Troubleshoot the Trouble

Bad airflow is a main explanation for an AC to frost over. Here’s how to figure out the issue:

  • Check the filter. Poor airflow through a filthy filter could be the problem. Check and replace 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 reduces airflow over the evaporator coil, which might cause it to freeze.
  • Look for obstructed return vents. These typically don’t have shiftable louvers, but furniture, rugs or curtains can still obstruct them.
  • Low refrigerant: While airflow restrictions are the most common culprit, your system could also be low on refrigerant. Depending on its age, it may have Freon® or Puron®. Not enough refrigerant necessitates pro attention from a certified HVAC technician. H2: Step 3: Contact an HVAC Professional at Service Experts Heating & Air Conditioning

If inadequate airflow doesn’t feel like the trouble, then another issue is leading your AC freeze up. If this is the case, merely letting it melt won’t take care of the trouble. The evaporator coil will probably continually freeze unless you fix the root symptom. Contact an HVAC specialist to check for issues with your air conditioner, which might include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run out. Insufficient refrigerant is a sign of a leak somewhere. Only a technician can locate the leak, mend it, and recharge the air conditioning to the appropriate level.
  • Filthy evaporator coil: If grime builds up on the coil, air can’t reach it, and it’s likely to freeze.
  • Nonfunctional blower: A faulty motor or unbalanced fan can halt airflow over the evaporator coil.
