Fast Steps for Fixing a Frozen Air Conditioner

Does the air coming from your supply registers unexpectedly seem not cold enough? Look at the indoor component of your air conditioner. This piece is located inside your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there might be crystals on the evaporator coil. The AC coil inside the system might have frosted over. You’ll need to melt it before it can cool your house again. 

Here’s the steps you should take. If you can’t get the coil frost-free, Peachtree Service Experts is here to help with air conditioning repair in Atlanta upheld by 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 chilled refrigerant from going to the outdoor compressor, which could harm it and result in a pricey repair. 

Next, switch the fan from “auto” to “on.” This makes hot airflow over the frozen coils to make them melt faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle. 

It can take not more than an hour or most of the day for the ice to melt, depending on the degree of the accumulation. While you’re waiting, watch the condensate pan underneath the AC unit. If the drain line is obstructed, it can spill over as the ice melts, possibly creating water damage. 

Step 2: Diagnose the Issue 

Bad airflow is a leading cause for an AC to become frozen. Here’s how to get to the bottom of the situation: 

  • Inspect the filter. Insufficient airflow through a clogged filter could be the problem. Look at and put in a new filter monthly or as soon as you notice dust buildup. 
  • Open any shut supply vents. Your residence’s supply registers should stay open all the time. Shutting vents limits airflow over the evaporator coil, which may lead it to freeze. 
  • Look for covered return vents. These often don’t use adjustable louvers, but furniture, rugs or curtains can still obstruct them. 
  • Not enough refrigerant: While airflow restrictions are the most frequent culprit, your air conditioner might also not have enough refrigerant. Depending on how old it is, it may use Freon®. Not enough refrigerant calls for professional attention from a certified HVAC tech. H2: Step 3: Contact an HVAC Professional at Peachtree Service Experts 

If poor airflow doesn’t appear to be the issue, then another issue is leading your AC freeze. If this is what’s going on, simply defrosting it won’t repair the trouble. The evaporator coil will probably keep freezing unless you fix the main symptom. Call an HVAC pro to look for issues with your air conditioner, which might include: 

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run low. Not enough refrigerant means there’s a leak somewhere. Only a tech can locate the leak, fix it, and recharge the air conditioner to the appropriate level. 
  • Grimy evaporator coil: If grime accumulates on the coil, air can’t get to it, and it’s likely to freeze. 
  • Broken blower: A bad motor or unbalanced fan can stop airflow over the evaporator coil.
