3 Simple Steps for Repairing a Frozen Air Conditioner

Does the air coming from your supply registers suddenly seem warm? Inspect the indoor component of your air conditioner. This piece is housed inside your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there might be ice on the evaporator coil. The AC coil within the system might have frozen. You’ll need to defrost it before it can cool your home again.

Here’s the things you should do. If you can’t get the coil frost-free, Stark Services is here to support you with air conditioning repair in Haltom City that includes a a 100% satisfaction guarantee.*

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

To begin—set the thermostat from “cool” to “off.” This halts chilly refrigerant from moving to the outdoor compressor, which could hurt it and lead to a costly repair.

Next, switch the fan from “auto” to “on.” This creates heated airflow over the frozen coils to help them melt faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It might take under an hour or the majority of the day for the ice to defrost, depending on the level of the buildup. While you’re waiting, watch the condensate pan below the AC unit. If the drain line is obstructed, it may cause a mess as the ice melts, possibly resulting in water damage.

Step 2: Troubleshoot the Issue

Bad airflow is a leading reason for an AC to frost over. Here’s how to figure out the problem:

  • Look at the filter. Insufficient airflow through a dirty filter could be the culprit. Check and put in a new filter monthly or immediately when you see dust buildup.
  • Open any sealed supply vents. Your residence’s supply registers should remain open all the time. Sealing vents reduces airflow over the evaporator coil, which might result in it freezing.
  • Be on the lookout for covered return vents. These typically don’t come with shiftable louvers, but furniture, rugs or curtains can still block them.
  • Insufficient refrigerant: While airflow restrictions are the most typical suspect, your air conditioning might also be low on refrigerant. Depending on when it was replaced, it may rely on Freon® or Puron®. Low refrigerant necessitates pro assistance from a certified HVAC tech.

If inadequate airflow doesn’t seem to be the problem, then another issue is causing your AC frost over. If this is what’s going on, just defrosting it won’t repair the issue. The evaporator coil will probably keep freezing unless you repair the root problem. Get in touch with an HVAC pro to check for troubles with your air conditioner, which may include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run low. Insufficient refrigerant means there’s a leak somewhere. Only a technician can find the leak, mend it, and recharge the system to the appropriate concentration.
  • Grimy evaporator coil: If dirt collects on the coil, air can’t reach it, and it’s apt to freeze.
  • Nonfunctional blower: A defective motor or unbalanced fan can stop airflow over the evaporator coil.
