3 Simple Ways to Restore a Frozen Air Conditioner

Does the air coming from your supply registers suddenly feel hot? Inspect the indoor part of your air conditioner. This part is located inside your furnace or air handler, if you rely on a heat pump. If there’s water leaking onto the floor, there may be frost on the evaporator coil. The AC coil inside the equipment may have frosted over. You’ll need to thaw it before it can cool your house again.

Here’s what to do. If you can’t get the coil defrosted, Service Experts Heating & Air Conditioning is here to help with air conditioning repair in Cocoa that includes a a 100% satisfaction guarantee.*

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

First things first—move the thermostat from “cool” to “off.” This stops cold refrigerant from flowing to the outdoor compressor, which could damage it and lead to an expensive repair.

Then, switch the fan from “auto” to “on.” This makes warm airflow over the crystallized coils to force them to thaw faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It can take not more than an hour or the better part of a day for the ice to melt, depending on the extent of the accumulation. While you’re waiting, keep an eye on the condensate pan underneath the AC unit. If the drain line is clogged, it might spill over as the ice melts, possibly creating water damage.

Step 2: Troubleshoot the Issue

Poor airflow is a primary explanation for an AC to freeze up. Here’s how to get to the bottom of the situation:

  • Check the filter. Poor airflow through a clogged filter could be the culprit. Look at and change the filter once a month or immediately when you see dust buildup.
  • Open any sealed supply vents. Your home’s supply registers should remain open all the time. Sealing vents reduces airflow over the evaporator coil, which might lead it to freeze.
  • Check for covered return vents. These often don’t have moveable louvers, but furniture, rugs or curtains can still obstruct them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent cause, your air conditioner may also have insufficient refrigerant. Depending on when it was installed, it may use Freon® or Puron®. Low refrigerant necessitates skilled support from a certified HVAC specialist.

If poor airflow doesn’t feel like the problem, then something else is leading your AC frost over. If this is what’s occurring, simply defrosting it won’t repair the trouble. The evaporator coil will possibly freeze again unless you fix the root cause. Call an HVAC professional to address problems with your air conditioner, which might include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run out. Not enough refrigerant indicates a leak somewhere. Only a specialist can pinpoint the leak, fix it, and recharge the air conditioner to the correct amount.
  • Dirty evaporator coil: If dust builds up on the coil, air can’t flow over it, and it’s likely to freeze.
  • Malfunctioning blower: A faulty motor or unbalanced fan may stop airflow over the evaporator coil.
