3 Quick Steps to Fix a Frozen Air Conditioner

Does the air emitting from your supply registers suddenly feel not cold enough? Inspect the indoor portion of your air conditioner. This component is situated inside 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 within the system could have frozen. You’ll need to melt it before it can cool your residence again.

Here’s the things you should do. If you can’t get the coil defrosted, Levy & Son Service Experts is here to assist you with air conditioning repair in Dallas upheld by a 100% satisfaction guarantee.*

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

First things first—set the thermostat from “cool” to “off.” This halts chilled refrigerant from going to the outdoor compressor, which could harm it and result in an expensive repair.

Next, switch the fan from “auto” to “on.” This produces warm airflow over the frosty coils to help them thaw faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.

It may take not more than an hour or the majority of the day for the ice to defrost, depending on the degree of the accumulation. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is obstructed, it might create a mess as the ice melts, potentially causing water damage.

Step 2: Diagnose the Trouble

Insufficient airflow is a main reason for an AC to become frozen. Here’s how to get to the bottom of the situation:

  • Exmaine the filter. Insufficient airflow through a dusty filter could be the issue. Look at and put in a new filter monthly or once you see dust buildup.
  • Open any sealed supply vents. Your residence’s supply registers should stay open constantly. Closing vents reduces airflow over the evaporator coil, which may result in it freezing.
  • Be on the lookout for covered return vents. These often don’t have shiftable louvers, but furniture, rugs or curtains can still obstruct them.
  • Low refrigerant: While airflow restrictions are the most frequent suspect, your system might also have insufficient refrigerant. Depending on its age, it may rely on Freon®. Not enough refrigerant calls for professional assistance from a certified HVAC technician. H2: Step 3: Call an HVAC Tech at Levy & Son Service Experts

If insufficient airflow doesn’t feel like the trouble, then something else is leading your AC frost over. If this is what’s occurring, simply defrosting it won’t fix the trouble. The evaporator coil will possibly freeze again unless you repair the underlying issue. Contact an HVAC professional to check for issues with your air conditioner, which can include:

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t get used up. Not enough refrigerant is a sign of a leak somewhere. Only a pro can pinpoint the leak, repair it, and recharge the system to the proper concentration.
  • Dirty evaporator coil: If dust collects on the coil, air can’t reach it, and it’s likely to freeze.
  • Nonfunctional blower: A defective motor or unbalanced fan may prevent airflow over the evaporator coil.
