3 Easy 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 situated inside your furnace or air handler, if you rely on a heat pump. If there’s water dripping onto the floor, there might be frost on the evaporator coil. The AC coil within the unit could have frozen. You’ll need to melt it before it can cool your residence again.

Here’s what to do. If you can’t get the coil frost-free, Gordon's Service Experts is here to support you with air conditioning repair in Oklahoma City that includes a 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 chilly refrigerant from moving to the outdoor compressor, which could hurt it and result in a costly repair.

Then, move the fan from “auto” to “on.” This makes warm airflow over the frosty 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 may take not more than an hour or the majority of the day for the ice to melt, depending on the amount of the ice. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is clogged, it can create a mess as the ice melts, possibly 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 situation:

  • Look at the filter. Inadequate airflow through a filthy filter could be the problem. Inspect and put in a new filter monthly or as soon as you see a layer of dust.
  • Open any sealed supply vents. Your home’s supply registers should stay open constantly. Shutting vents reduces airflow over the evaporator coil, which can result in it freezing.
  • Check for covered return vents. These usually don’t have adjustable louvers, but furniture, rugs or curtains can still cover them.
  • Not enough refrigerant: While airflow restrictions are the most common suspect, your air conditioning could also have insufficient refrigerant. Depending on how old it is, it may rely on Freon® or Puron®. Not enough refrigerant necessitates pro support from a certified HVAC technician.

If inadequate airflow doesn’t feel like the issue, then another problem is causing your AC freeze up. If this is what’s going on, merely letting it melt won’t repair the issue. The evaporator coil will possibly continually freeze unless you take care of the main problem. Contact an HVAC pro to look for troubles with your air conditioner, which may include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Not enough refrigerant signals a leak somewhere. Only a professional can pinpoint the leak, fix it, and recharge the system to the correct concentration.
  • Filthy evaporator coil: If dirt accumulates on the coil, air can’t flow over it, and it’s likely to freeze.
  • Nonfunctional blower: A broken motor or unbalanced fan might stop airflow over the evaporator coil.
