3 Simple Steps to Fix a Frozen Air Conditioner

Does the air emitting from your supply registers suddenly feel not cold enough? Check the indoor portion of your air conditioner. This component is situated inside your furnace or air handler, if you rely on a heat pump. If there’s water seeping onto the floor, there may be frost on the evaporator coil. The AC coil in the unit could have frosted over. You’ll need to melt it before it can cool your home again.

Here’s the things you should do. If you can’t get the coil frost-free, Service Experts Heating & Air Conditioning is here to help with air conditioning repair in Fort Lauderdale upheld by a 100% satisfaction guarantee.*

Step 1: Set the Air Conditioning to Off and the Blower On

To begin—switch the thermostat from “cool” to “off.” This halts cold refrigerant from flowing to the outdoor compressor, which could hurt it and result in an expensive repair.

Next, move the fan from “auto” to “on.” This produces heated airflow over the frosty coils to help them thaw faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It may take less than an hour or the majority of the day for the ice to melt, depending on the degree of the accumulation. While you’re waiting, watch the condensate pan underneath the AC unit. If the drain line is clogged, it can cause a mess as the ice melts, potentially creating water damage.

Step 2: Diagnose the Issue

Not enough airflow is a prime explanation for an AC to become frozen. Here’s how to get to the bottom of the issue:

  • Exmaine the filter. Low airflow through a dirty filter could be the culprit. Inspect and change the filter monthly or immediately when you see dust accumulation.
  • Open any shut supply vents. Your residence’s supply registers should be open always. Sealing vents limits airflow over the evaporator coil, which may result in it freezing.
  • Be on the lookout for covered return vents. These typically don’t have moveable louvers, but furniture, rugs or curtains can still block them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent cause, your air conditioner could also have insufficient refrigerant. Depending on its age, it may have Freon®. Low refrigerant requires pro support from a certified HVAC specialist. H2: Step 3: Get in Touch with an HVAC Specialist at Service Experts Heating & Air Conditioning

If insufficient airflow doesn’t appear to be the issue, then another issue is making your AC freeze up. If this is what’s happening, merely defrosting it won’t fix the issue. The evaporator coil will possibly keep freezing unless you take care of the root issue. Contact an HVAC professional to check for issues with your air conditioner, which might include:

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run low. Insufficient refrigerant is a sign of a leak somewhere. Only a specialist can pinpoint the leak, mend it, and recharge the system to the proper level.
  • Grimy evaporator coil: If dust builds up on the coil, air can’t get to it, and it’s liable to freeze.
  • Nonfunctional blower: A broken motor or unbalanced fan can prevent airflow over the evaporator coil.
