Fix Your Frozen Air Conditioner with These 3 Quick Tips

Does the air flowing from your supply registers abruptly feel not cold enough? Inspect the indoor portion of your air conditioner. This part is located within your furnace or air handler, if you rely on a heat pump. If there’s water leaking onto the floor, there could be frost on the evaporator coil. The AC coil within the system may have frozen over. You’ll need to melt 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, Service Experts Heating & Air Conditioning is here to assist you with air conditioning repair in Naples backed by a 100% satisfaction guarantee.*

Step 1: Set the Air Conditioning to Off and the Blower On

First things first—switch the thermostat from “cool” to “off.” This halts chilly refrigerant from moving to the outdoor compressor, which could harm it and cause an expensive repair.

After that, adjust the fan from “auto” to “on.” This produces hot airflow over the frosty coils to help them melt faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.

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

Step 2: Troubleshoot the Issue

Not enough airflow is a main explanation for an AC to freeze up. Here’s how to troubleshoot the problem:

  • Look at the filter. Inadequate airflow through a dirty filter could be the issue. Inspect and replace the filter once a month or immediately when you notice dust accumulation.
  • Open any closed supply vents. Your home’s supply registers should be open constantly. Sealing vents limits airflow over the evaporator coil, which could lead it to freeze.
  • Be on the lookout for obstructed return vents. These typically don’t have moveable louvers, but furniture, rugs or curtains can still block them.
  • Insufficient refrigerant: While airflow restrictions are the most common cause, your air conditioner may also be low on refrigerant. Depending on how old it is, it may use Freon®. Not enough refrigerant requires skilled assistance from a certified HVAC technician. H2: Step 3: Contact an HVAC Pro at Service Experts Heating & Air Conditioning

If insufficient airflow doesn’t appear to be the trouble, then something else is causing your AC freeze up. If this is what’s going on, simply defrosting it won’t take care of the issue. The evaporator coil will possibly keep freezing unless you take care of the main issue. Get in touch with an HVAC specialist to address problems with your air conditioner, which might include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Insufficient refrigerant means there’s a leak somewhere. Only a specialist can find the leak, fix it, and recharge the system to the correct amount.
  • Filthy evaporator coil: If grime builds up on the coil, air can’t reach it, and it’s apt to freeze.
  • Nonfunctional blower: A faulty motor or unbalanced fan may prevent airflow over the evaporator coil.
