Get Your Frozen Air Conditioner Working Again with These 3 Quick Tips

Does the air coming from your supply registers abruptly seem warm? Inspect the indoor part of your air conditioner. This component is located within your furnace or air handler, if you rely on a heat pump. If there’s water leaking onto the floor, there might be frost on the evaporator coil. The AC coil inside the system could have frozen. 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, 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 get started—switch the thermostat from “cool” to “off.” This stops chilly refrigerant from flowing to the outdoor compressor, which could hurt it and cause an expensive repair.

Next, adjust the fan from “auto” to “on.” This creates 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 level of the ice. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is obstructed, it could create a mess as the ice melts, likely creating water damage.

Step 2: Troubleshoot the Trouble

Insufficient airflow is a prime cause for an AC to become frozen. Here’s how to get to the bottom of the problem:

  • Check the filter. Poor airflow through a clogged filter could be the culprit. Inspect and put in a new filter each month or immediately when you see a layer of dust.
  • Open any sealed supply vents. Your residence’s supply registers should be open always. Closing vents limits airflow over the evaporator coil, which could lead it to freeze.
  • Be on the lookout for covered return vents. These usually don’t use 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 its age, it may rely on Freon® or Puron®. Not enough refrigerant calls for 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 trouble, then another problem is making your AC frost over. If this is what’s going on, just thawing it out won’t take care of the issue. The evaporator coil will probably keep freezing unless you fix the underlying issue. Call an HVAC tech to address issues with your air conditioner, which can include:

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