3 Fast Steps to Fix a Frozen Air Conditioner

Does the air flowing from your supply registers unexpectedly appear not cold enough? Check the indoor component of your air conditioner. This component is located in your furnace or air handler, if you rely on a heat pump. If there’s water dripping onto the floor, there might be ice on the evaporator coil. The AC coil inside the unit may have frozen. You’ll need to thaw it before it can cool your home again.

Here’s the things you should do. If you can’t get the coil frost-free, Service Experts Heating & Air Conditioning is here to assist you with air conditioning repair in North America upheld by a 100% satisfaction guarantee.*

Step 1: Set the Air Conditioning to 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 cause an expensive repair.

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

It could take less than an hour or the majority of the day for the ice to melt, depending on the extent of the ice. While you’re waiting, check the condensate pan under the AC unit. If the drain line is clogged, it may create a mess as the ice melts, possibly causing water damage.

Step 2: Troubleshoot the Trouble

Not enough airflow is a primary explanation for an AC to become frozen. Here’s how to figure out the problem:

  • Check the filter. Poor airflow through a dusty filter could be the problem. Check and put in a new filter once a month or immediately when you observe a layer of dust.
  • Open any closed supply vents. Your home’s supply registers should stay open always. Shutting vents decreases airflow over the evaporator coil, which may result in it freezing.
  • Be on the lookout for covered return vents. These usually don’t have shiftable louvers, but furniture, rugs or curtains can still cover them.
  • Insufficient refrigerant: While airflow restrictions are the most typical cause, your air conditioning might also be low on refrigerant. Depending on when it was replaced, it may rely on Freon® or Puron®. Low refrigerant requires professional attention from a certified HVAC specialist.

If poor airflow doesn’t appear to be the problem, then another issue is causing your AC freeze up. If this is what’s going on, simply defrosting it won’t take care of the problem. The evaporator coil will possibly freeze again unless you repair the underlying symptom. Get in touch with an HVAC professional to look for issues with your air conditioner, which can include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Low refrigerant indicates a leak somewhere. Only a pro can locate the leak, mend it, and recharge the air conditioning to the correct amount.
  • Grimy evaporator coil: If grime accumulates on the coil, air can’t get to it, and it’s apt to freeze.
  • Malfunctioning blower: A bad motor or unbalanced fan can halt airflow over the evaporator coil.
