3 Easy Ways to Restore a Frozen Air Conditioner

Does the air flowing from your supply registers abruptly feel hot? Look at the indoor part of your air conditioner. This component is housed inside your furnace or air handler, if you use a heat pump. If there’s water dripping onto the floor, there might be crystals on the evaporator coil. The AC coil in the unit could have frosted over. You’ll need to defrost it before it can cool your residence 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 Fort Myers upheld by a 100% satisfaction guarantee.*

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

To get started—set the thermostat from “cool” to “off.” This stops chilled refrigerant from flowing to the outdoor compressor, which could harm it and cause an expensive repair.

After that, switch the fan from “auto” to “on.” This creates hot airflow over the crystallized coils to force them to thaw faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.

It can take less than an hour or most of the day for the ice to thaw, depending on the amount of the accumulation. While you’re waiting, check the condensate pan underneath the AC unit. If the drain line is blocked, it might create a mess as the ice melts, potentially resulting in water damage.

Step 2: Diagnose the Situation

Not enough airflow is a chief cause for an AC to freeze up. Here’s how to troubleshoot the issue:

  • Look at the filter. Inadequate airflow through a dirty filter could be to blame. Inspect and replace the filter once a month or immediately when you observe dust accumulation.
  • Open any shut supply vents. Your residence’s supply registers should remain open always. Closing vents decreases airflow over the evaporator coil, which can cause it to freeze.
  • Be on the lookout for obstructed return vents. These typically don’t use shiftable louvers, but furniture, rugs or curtains can still cover them.
  • Not enough refrigerant: While airflow restrictions are the most common cause, your air conditioning might also have insufficient refrigerant. Depending on when it was replaced, it may have Freon®. Low refrigerant calls for pro attention from a certified HVAC tech.

If inadequate airflow doesn’t appear to be the trouble, then something else is leading your AC freeze. If this is what’s happening, just thawing it out won’t repair the trouble. The evaporator coil will possibly freeze again unless you take care of the main issue. Get in touch with an HVAC technician to check for issues with your air conditioner, which can include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run out. Insufficient refrigerant means there’s a leak somewhere. Only a technician can find the leak, fix it, and recharge the system to the correct level.
  • Filthy evaporator coil: If dirt collects on the coil, air can’t get to it, and it’s liable to freeze.
  • Broken blower: A bad motor or unbalanced fan can halt airflow over the evaporator coil.
