3 Fast Ways to Restore a Frozen Air Conditioner

Does the air emitting from your supply registers abruptly feel hot? Look at the indoor component of your air conditioner. This component is housed inside your furnace or air handler, if you have a heat pump. If there’s water dripping onto the floor, there may be frost on the evaporator coil. The AC coil in the system may have frozen over. 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 back to normal, Bryant Heating & Cooling Service Experts is here to support you with air conditioning repair in Windsor that includes a a 100% satisfaction guarantee.*

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

To begin—move the thermostat from “cool” to “off.” This prevents chilly refrigerant from going to the outdoor compressor, which could hurt it and result in an expensive repair.

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

It might take not more than an hour or the majority of the day for the ice to thaw, depending on the extent of the ice. While you’re waiting, check the condensate pan under the AC unit. If the drain line is blocked, it can cause a mess as the ice melts, potentially creating water damage.

Step 2: Diagnose the Problem

Bad airflow is a main reason for an AC to frost over. Here’s how to get to the bottom of the issue:

  • Check the filter. Insufficient airflow through a dirty filter could be the problem. Look at and put in a new filter monthly or immediately when you observe a layer of dust.
  • Open any sealed supply vents. Your house’s supply registers should remain open all the time. Closing vents reduces airflow over the evaporator coil, which may result in it freezing.
  • Look for covered return vents. These typically don’t use adjustable louvers, but furniture, rugs or curtains can still obstruct them.
  • Low refrigerant: While airflow restrictions are the most frequent culprit, your air conditioning might also have insufficient refrigerant. Depending on how old it is, it may rely on Freon® or Puron®. Not enough refrigerant requires professional help from a certified HVAC tech.

If inadequate airflow doesn’t feel like the problem, then another issue is leading your AC freeze. If this is what’s happening, merely letting it melt won’t take care of the problem. The evaporator coil is likely to freeze again unless you take care of the underlying symptom. Call an HVAC tech to look for issues with your air conditioner, which may include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t get used up. Not enough refrigerant signals a leak somewhere. Only a professional can pinpoint the leak, repair it, and recharge the air conditioning to the proper concentration.
  • Dirty evaporator coil: If grime builds up on the coil, air can’t flow over it, and it’s likely to freeze.
  • Malfunctioning blower: A faulty motor or unbalanced fan could halt airflow over the evaporator coil.
