3 Quick Ways to Restore a Frozen Air Conditioner

Does the air emitting from your supply registers unexpectedly feel hot? Look at the indoor portion 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 may be crystals on the evaporator coil. The AC coil inside the system could have frozen over. You’ll need to thaw it before it can cool your home again.

Here’s what to do. If you can’t get the coil frost-free, Falso Service Experts is here to assist you with air conditioning repair in East Syracuse backed by a 100% satisfaction guarantee.*

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

To begin—set the thermostat from “cool” to “off.” This stops chilly refrigerant from flowing to the outdoor compressor, which could damage it and lead to an expensive repair.

After that, move the fan from “auto” to “on.” This creates heated airflow over the frosty coils to make them melt faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It could take less than an hour or most of the day for the ice to thaw, 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 blocked, it might spill over as the ice melts, potentially resulting in water damage.

Step 2: Diagnose the Situation

Poor airflow is a main reason for an AC to become frozen. Here’s how to get to the bottom of the situation:

  • Exmaine the filter. Insufficient airflow through a dirty filter could be the culprit. Look at and put in a new filter each month or once you observe dust buildup.
  • Open any shut supply vents. Your residence’s supply registers should stay open all the time. Shutting vents decreases airflow over the evaporator coil, which could lead it to freeze.
  • Look for covered return vents. These typically don’t use moveable louvers, but furniture, rugs or curtains can still obstruct them.
  • Insufficient refrigerant: While airflow restrictions are the most common culprit, your air conditioning could also be low on refrigerant. Depending on its age, it may use Freon® or Puron®. Not enough refrigerant calls for pro help from a certified HVAC technician. H2: Step 3: Contact an HVAC Professional at Falso Service Experts

If insufficient airflow doesn’t feel like the problem, then something else is causing your AC freeze up. If this is what’s occurring, just letting it melt won’t fix the trouble. The evaporator coil will possibly freeze again unless you fix the root issue. Call an HVAC tech to look for issues with your air conditioner, which can include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run low. Low refrigerant is a sign of a leak somewhere. Only a technician can find the leak, mend it, and recharge the air conditioner to the correct concentration.
  • Grimy evaporator coil: If dust accumulates on the coil, air can’t reach it, and it’s likely to freeze.
  • Malfunctioning blower: A defective motor or unbalanced fan can prevent airflow over the evaporator coil.
