3 Easy Ways to Restore a Frozen Air Conditioner

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

Here’s the steps you should take. If you can’t get the coil back to normal, Stark Services is here to support you with air conditioning repair in Fort Worth 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 chilled refrigerant from flowing to the outdoor compressor, which could hurt it and lead to a costly repair.

Next, switch the fan from “auto” to “on.” This makes hot 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 trigger a cooling cycle.

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

Step 2: Troubleshoot the Issue

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

  • Check the filter. Insufficient airflow through a dusty filter could be the culprit. Check and replace the filter each month or immediately when you see dust accumulation.
  • 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 lead it to freeze.
  • Be on the lookout for obstructed return vents. These typically don’t come with moveable louvers, but furniture, rugs or curtains can still block them.
  • Not enough 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 have Freon®. Low refrigerant calls for pro assistance from a certified HVAC specialist. H2: Step 3: Get in Touch with an HVAC Pro at Stark Services

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

  • Refrigerant leak: AC units continuously use 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 accumulates on the coil, air can’t reach it, and it’s apt to freeze.
  • Broken blower: A defective motor or unbalanced fan can stop airflow over the evaporator coil.
