3 Quick Steps for Repairing a Frozen Air Conditioner

Does the air flowing from your supply registers abruptly seem not cold enough? Inspect the indoor component of your air conditioner. This part is located in your furnace or air handler, if you have a heat pump. If there’s water dripping onto the floor, there could be crystals on the evaporator coil. The AC coil within the unit could have frozen. You’ll need to defrost it before it can cool your residence again.

Here’s what to do. If you can’t get the coil back to normal, Gordon's Service Experts is here to support you with air conditioning repair in Oklahoma City upheld by a 100% satisfaction guarantee.*

Step 1: Set the Air Conditioning to Off and the Blower On

To get started—set the thermostat from “cool” to “off.” This stops chilled refrigerant from moving to the outdoor compressor, which could hurt it and cause a costly repair.

Then, move the fan from “auto” to “on.” This creates warm airflow over the crystallized coils to force them to thaw faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.

It could take under an hour or most of the day for the ice to melt, depending on the amount of the accumulation. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is clogged, it can overflow as the ice melts, likely creating water damage.

Step 2: Troubleshoot the Issue

Bad airflow is a prime explanation for an AC to freeze up. Here’s how to troubleshoot the issue:

  • Look at the filter. Inadequate airflow through a filthy filter could be the problem. Inspect and replace the filter each month or as soon as you see a layer of dust.
  • Open any shut supply vents. Your home’s supply registers should be open constantly. Sealing vents reduces airflow over the evaporator coil, which might lead it to freeze.
  • Check for obstructed return vents. These often don’t have adjustable louvers, but furniture, rugs or curtains can still cover them.
  • Insufficient refrigerant: While airflow restrictions are the most common suspect, your air conditioner might also have insufficient refrigerant. Depending on how old it is, it may have Freon® or Puron®. Not enough refrigerant necessitates skilled support from a certified HVAC technician.

If inadequate airflow doesn’t feel like the issue, then another issue is causing your AC freeze up. If this is what’s going on, merely defrosting it won’t repair the issue. The evaporator coil will probably continually freeze unless you fix the main cause. Contact an HVAC pro to address troubles with your air conditioner, which may include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t get used up. Insufficient refrigerant indicates a leak somewhere. Only a professional can pinpoint the leak, fix it, and recharge the system to the correct concentration.
  • Grimy evaporator coil: If dirt accumulates on the coil, air can’t get to it, and it’s apt to freeze.
  • Nonfunctional blower: A broken motor or unbalanced fan might halt airflow over the evaporator coil.
