Fix Your Frozen Air Conditioner with These 3 Quick Tips

Does the air emitting from your supply registers abruptly appear not cold enough? Check the indoor portion of your air conditioner. This part is situated within your furnace or air handler, if you use a heat pump. If there’s water seeping onto the floor, there might be ice on the evaporator coil. The AC coil within the unit may have frozen. You’ll need to thaw it before it can cool your residence again.

Here’s the steps you should take. If you can’t get the coil frost-free, Becht/Givens Service Experts is here to assist you with air conditioning repair in Louisville upheld by a 100% satisfaction guarantee.*

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

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

After that, switch the fan from “auto” to “on.” This produces heated airflow over the frozen coils to help them thaw faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It could take under an hour or the better part of a day for the ice to melt, depending on the level of the ice. While you’re waiting, check the condensate pan below the AC unit. If the drain line is clogged, it can create a mess as the ice melts, possibly creating water damage.

Step 2: Diagnose the Problem

Poor airflow is a chief reason for an AC to freeze up. Here’s how to troubleshoot the situation:

  • Exmaine the filter. Poor airflow through a clogged filter could be the issue. Check and replace the filter monthly or immediately when you observe dust accumulation.
  • Open any closed supply vents. Your residence’s supply registers should stay open constantly. Shutting vents reduces airflow over the evaporator coil, which may cause it to freeze.
  • Be on the lookout for blocked return vents. These typically don’t come with adjustable louvers, but furniture, rugs or curtains can still obstruct them.
  • Low refrigerant: While airflow restrictions are the most frequent cause, your air conditioning could also not have enough refrigerant. Depending on when it was replaced, it may rely on Freon® or Puron®. Not enough refrigerant necessitates professional help from a certified HVAC technician.

If insufficient airflow doesn’t seem to be the issue, then another problem is causing your AC freeze up. If this is what’s happening, merely thawing it out won’t take care of the trouble. The evaporator coil will probably continually freeze unless you repair the underlying issue. Contact an HVAC specialist to check for problems with your air conditioner, which can include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Low refrigerant means there’s a leak somewhere. Only a specialist can locate the leak, fix it, and recharge the air conditioner to the proper amount.
  • Filthy evaporator coil: If dust collects on the coil, air can’t reach it, and it’s likely to freeze.
  • Broken blower: A defective motor or unbalanced fan could stop airflow over the evaporator coil.
