Repair Your Frozen Air Conditioner with These 3 Simple Tips

Does the air emitting from your supply registers abruptly appear hot? Check the indoor component 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 leaking onto the floor, there might be crystals on the evaporator coil. The AC coil within the unit may have frozen over. 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 defrosted, Service Experts Heating & Air Conditioning is here to assist you with air conditioning repair in West Palm Beach upheld by a 100% satisfaction guarantee.*

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

To begin—switch the thermostat from “cool” to “off.” This prevents chilled refrigerant from moving to the outdoor compressor, which could damage it and cause an expensive repair.

After that, move the fan from “auto” to “on.” This produces warm 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 start a cooling cycle.

It might take not more than an hour or most of the day for the ice to thaw, depending on the degree of the accumulation. While you’re waiting, watch the condensate pan under the AC unit. If the drain line is clogged, it can overflow as the ice melts, likely creating water damage.

Step 2: Pinpoint the Situation

Bad 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. Insufficient airflow through a dirty filter could be the issue. Check and replace the filter once a month or immediately when you observe a layer of dust.
  • Open any sealed supply vents. Your home’s supply registers should stay open constantly. Closing vents reduces airflow over the evaporator coil, which could lead it to freeze.
  • Check for blocked return vents. These usually don’t have shiftable louvers, but furniture, rugs or curtains can still obstruct them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent suspect, your system may also be low on refrigerant. Depending on when it was installed, it may have Freon® or Puron®. Not enough refrigerant necessitates pro attention from a certified HVAC specialist. H2: Step 3: Contact an HVAC Technician at Service Experts Heating & Air Conditioning

If low airflow doesn’t feel like the trouble, then something else is causing your AC freeze. If this is what’s occurring, simply letting it melt won’t repair the issue. The evaporator coil will probably keep freezing unless you repair the root cause. Contact an HVAC professional to address problems with your air conditioner, which might include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run out. Not enough refrigerant indicates a leak somewhere. Only a technician can find the leak, repair it, and recharge the air conditioning to the appropriate amount.
  • Grimy evaporator coil: If grime builds up on the coil, air can’t reach it, and it’s likely to freeze.
  • Nonfunctional blower: A faulty motor or unbalanced fan might stop airflow over the evaporator coil.
