Fix Your Frozen Air Conditioner with These 3 Simple Tips

Does the air coming from your supply registers abruptly feel warm? Check the indoor portion of your air conditioner. This piece is housed within your furnace or air handler, if you have a heat pump. If there’s water dripping onto the floor, there could be frost on the evaporator coil. The AC coil in the equipment could have frozen. You’ll need to thaw it before it can cool your residence again.

Here’s the steps you should take. If you can’t get the coil back to normal, Midway Services is here to support you with air conditioning repair in Clearwater backed by a 100% satisfaction guarantee.*

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

First things first—set the thermostat from “cool” to “off.” This stops chilly refrigerant from going to the outdoor compressor, which could harm it and result in a costly repair.

After that, switch the fan from “auto” to “on.” This makes warm airflow over the frosty coils to make them thaw faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It could take not more than an hour or most of the day for the ice to thaw, depending on the extent of the buildup. While you’re waiting, keep an eye on the condensate pan underneath the AC unit. If the drain line is clogged, it may spill over as the ice melts, possibly resulting in water damage.

Step 2: Pinpoint the Situation

Not enough airflow is a prime explanation for an AC to freeze up. Here’s how to get to the bottom of the issue:

  • Exmaine the filter. Inadequate airflow through a filthy filter could be the problem. Check and replace the filter once a month or immediately when you notice dust accumulation.
  • Open any sealed supply vents. Your house’s supply registers should remain open all the time. Sealing vents decreases airflow over the evaporator coil, which can lead it to freeze.
  • Check for blocked return vents. These often don’t use moveable louvers, but furniture, rugs or curtains can still obstruct them.
  • Insufficient refrigerant: While airflow restrictions are the most common cause, your system might also have insufficient refrigerant. Depending on its age, it may have Freon® or Puron®. Not enough refrigerant necessitates skilled assistance from a certified HVAC technician. H2: Step 3: Get in Touch with an HVAC Expert at Midway Services

If low airflow doesn’t appear to be the issue, then another issue is causing your AC freeze up. If this is what’s going on, merely defrosting it won’t take care of the issue. The evaporator coil will possibly freeze again unless you fix the main problem. Get in touch with an HVAC technician to address issues with your air conditioner, which can include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Low refrigerant signals a leak somewhere. Only a technician can pinpoint the leak, mend it, and recharge the system to the proper level.
  • Dirty evaporator coil: If grime accumulates on the coil, air can’t flow over it, and it’s liable to freeze.
  • Nonfunctional blower: A faulty motor or unbalanced fan can stop airflow over the evaporator coil.
