3 Simple Ways to Repair a Frozen Air Conditioner

Does the air emitting from your supply registers abruptly feel not cold enough? Look at the indoor portion of your air conditioner. This piece is situated inside your furnace or air handler, if you use a heat pump. If there’s water dripping onto the floor, there might be crystals on the evaporator coil. The AC coil inside the system 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, Eveready Service Experts is here to assist you with air conditioning repair in Richmond that includes a a 100% satisfaction guarantee.*

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

To begin—set the thermostat from “cool” to “off.” This halts chilled refrigerant from moving to the outdoor compressor, which could damage it and cause an expensive repair.

Then, move the fan from “auto” to “on.” This makes warm airflow over the crystallized coils to make them melt faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.

It can take under an hour or most of the day for the ice to thaw, depending on the level of the ice. While you’re waiting, check the condensate pan underneath the AC unit. If the drain line is clogged, it may cause a mess as the ice melts, likely causing water damage.

Step 2: Diagnose the Issue

Bad airflow is a prime cause for an AC to freeze up. Here’s how to get to the bottom of the issue:

  • Inspect the filter. Inadequate airflow through a filthy filter could be the problem. Inspect and replace the filter once a month or immediately when you observe dust buildup.
  • Open any shut supply vents. Your residence’s supply registers should remain open constantly. Shutting vents reduces airflow over the evaporator coil, which could cause it to freeze.
  • Look for covered return vents. These usually don’t use shiftable louvers, but furniture, rugs or curtains can still obstruct them.
  • Insufficient refrigerant: While airflow restrictions are the most typical suspect, your air conditioner could also not have enough refrigerant. Depending on when it was installed, it may rely on Freon® or Puron®. Insufficient refrigerant requires pro help from a certified HVAC technician.

If poor airflow doesn’t appear to be the issue, then another issue is causing your AC freeze up. If this is what’s occurring, merely defrosting it won’t fix the problem. The evaporator coil will probably keep freezing unless you take care of the underlying symptom. Get in touch with an HVAC tech to address troubles with your air conditioner, which can include:

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run low. Low refrigerant indicates a leak somewhere. Only a specialist can locate the leak, fix it, and recharge the system to the correct amount.
  • Grimy evaporator coil: If dust accumulates on the coil, air can’t reach it, and it’s likely to freeze.
  • Malfunctioning blower: A defective motor or unbalanced fan can halt airflow over the evaporator coil.
