3 Fast Steps to Fix a Frozen Air Conditioner

Does the air coming from your supply registers abruptly seem warm? Inspect the indoor part of your air conditioner. This component is situated within your furnace or air handler, if you rely on a heat pump. If there’s water seeping onto the floor, there could be frost on the evaporator coil. The AC coil inside the system might 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, Comfortech Service Experts is here to support you with air conditioning repair in Jackson backed by 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 stops chilly refrigerant from moving to the outdoor compressor, which could hurt it and cause an expensive repair.

Next, move the fan from “auto” to “on.” This makes hot airflow over the frosty coils to make them defrost faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.

It might take not more than an hour or the majority of the day for the ice to melt, depending on the extent of the accumulation. While you’re waiting, keep an eye on the condensate pan underneath the AC unit. If the drain line is obstructed, it may overflow as the ice melts, possibly resulting in water damage.

Step 2: Troubleshoot the Trouble

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

  • Look at the filter. Poor airflow through a clogged filter could be to blame. Inspect and replace the filter monthly or once you see a layer of dust.
  • Open any shut supply vents. Your residence’s supply registers should stay open constantly. Closing vents decreases airflow over the evaporator coil, which could result in it freezing.
  • Be on the lookout for covered return vents. These often don’t come with adjustable louvers, but furniture, rugs or curtains can still block them.
  • Insufficient refrigerant: While airflow restrictions are the most common culprit, your system might also not have enough refrigerant. Depending on when it was installed, it may have Freon®. Not enough refrigerant necessitates professional assistance from a certified HVAC specialist. H2: Step 3: Call an HVAC Professional at Comfortech Service Experts

If poor airflow doesn’t appear to be the issue, then another issue is making your AC freeze. If this is what’s going on, just thawing it out won’t repair the issue. The evaporator coil will possibly keep freezing unless you take care of the underlying issue. Call an HVAC tech to address troubles with your air conditioner, which can include:

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run out. Not enough refrigerant is a sign of a leak somewhere. Only a professional can locate the leak, mend it, and recharge the system to the correct concentration.
  • Grimy evaporator coil: If dust accumulates on the coil, air can’t reach it, and it’s apt to freeze.
  • Malfunctioning blower: A defective motor or unbalanced fan can stop airflow over the evaporator coil.
