3 Simple Ways to Restore a Frozen Air Conditioner

Does the air coming from your supply registers suddenly feel not cold enough? Look at the indoor component of your air conditioner. This part is situated inside your furnace or air handler, if you have 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 frozen over. You’ll need to thaw it before it can cool your residence 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 Melbourne upheld by 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 halts 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 creates warm airflow over the crystallized coils to make them thaw faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.

It can take not more than an hour or the better part of a day for the ice to defrost, depending on the extent of the ice. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is clogged, it might spill over as the ice melts, likely resulting in 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. Inspect and change the filter once a month or once 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 typical cause, your air conditioning may also not have enough refrigerant. Depending on when it was installed, it may use Freon®. Low refrigerant calls for pro support from a certified HVAC tech. H2: Step 3: Get in Touch with an HVAC Expert at Service Experts Heating & Air Conditioning

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 letting it melt won’t repair the trouble. The evaporator coil will probably freeze again unless you take care of the main cause. Call an HVAC technician to look for problems with your air conditioner, which might include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Not enough refrigerant indicates a leak somewhere. Only a specialist can locate the leak, fix it, and recharge the air conditioner to the appropriate concentration.
  • Dirty evaporator coil: If dust builds up on the coil, air can’t flow over it, and it’s apt to freeze.
  • Malfunctioning blower: A faulty motor or unbalanced fan may halt airflow over the evaporator coil.
