Fix Your Frozen Air Conditioner with These 3 Quick Tips

Does the air emitting from your supply registers unexpectedly seem 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 leaking onto the floor, there could be ice on the evaporator coil. The AC coil in the unit may have frozen. 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 back to normal, Becht/Givens Service Experts is here to support you with air conditioning repair in Louisville that includes a 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 chilly refrigerant from flowing to the outdoor compressor, which could hurt it and lead to a costly repair.

After that, switch the fan from “auto” to “on.” This produces hot airflow over the frozen 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 could take under an hour or the better part of a day for the ice to melt, depending on the extent of the accumulation. While you’re waiting, watch the condensate pan below the AC unit. If the drain line is clogged, it can create a mess as the ice melts, likely resulting in water damage.

Step 2: Diagnose the Situation

Low airflow is a leading cause for an AC to freeze up. Here’s how to troubleshoot the issue:

  • Exmaine the filter. Low airflow through a clogged filter could be the issue. Check and put in a new filter each month or immediately when you observe dust accumulation.
  • Open any closed supply vents. Your residence’s supply registers should be 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 typical cause, your air conditioner might also have insufficient refrigerant. Depending on when it was replaced, it may have Freon®. Not enough refrigerant necessitates professional help from a certified HVAC technician. H2: Step 3: Contact an HVAC Professional at Becht/Givens Service Experts

If low airflow doesn’t appear to be the issue, then another problem is causing your AC freeze up. If this is what’s happening, just thawing it out won’t repair the problem. The evaporator coil will possibly keep freezing unless you repair the underlying issue. Get in touch with an HVAC specialist to check for problems with your air conditioner, which can include:

  • Refrigerant leak: AC units keep using 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 concentration.
  • Filthy evaporator coil: If dirt accumulates on the coil, air can’t reach it, and it’s likely to freeze.
  • Nonfunctional blower: A faulty motor or unbalanced fan may stop airflow over the evaporator coil.
