Fix Your Frozen Air Conditioner with These 3 Fast Tips

Does the air flowing from your supply registers suddenly appear not cold enough? Check the indoor part of your air conditioner. This piece is located within your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there could be ice on the evaporator coil. The AC coil in the unit may have frozen over. You’ll need to defrost it before it can cool your house again.

Here’s what to do. If you can’t get the coil back to normal, Service Experts Heating & Air Conditioning is here to support you with air conditioning repair in Miami backed by a 100% satisfaction guarantee.*

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

To get started—move the thermostat from “cool” to “off.” This halts cold refrigerant from going to the outdoor compressor, which could harm it and lead to an expensive repair.

Then, move the fan from “auto” to “on.” This produces warm airflow over the crystallized coils to make them defrost faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.

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

Step 2: Diagnose the Situation

Poor airflow is a main cause for an AC to freeze up. Here’s how to troubleshoot the situation:

  • Inspect the filter. Low airflow through a dirty filter could be the culprit. Look at and put in a new filter monthly or immediately when you see dust buildup.
  • Open any sealed supply vents. Your residence’s supply registers should stay open all the time. Shutting vents decreases airflow over the evaporator coil, which could cause it to freeze.
  • Be on the lookout for blocked return vents. These usually don’t come with moveable louvers, but furniture, rugs or curtains can still obstruct them.
  • Not enough refrigerant: While airflow restrictions are the most typical suspect, your system may also be low on refrigerant. Depending on how old it is, it may have Freon®. Insufficient refrigerant calls for pro help from a certified HVAC specialist. H2: Step 3: Call an HVAC Pro at Service Experts Heating & Air Conditioning

If poor airflow doesn’t appear to be the problem, then another issue is leading your AC frost over. If this is what’s occurring, merely thawing it out won’t repair the trouble. The evaporator coil is likely to keep freezing unless you take care of the underlying symptom. Contact an HVAC specialist to look for issues with your air conditioner, which might include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run low. Insufficient refrigerant means there’s a leak somewhere. Only a specialist can pinpoint the leak, repair it, and recharge the air conditioner to the proper amount.
  • Grimy evaporator coil: If grime collects on the coil, air can’t flow over it, and it’s liable to freeze.
  • Malfunctioning blower: A faulty motor or unbalanced fan could halt airflow over the evaporator coil.
