Simple Steps for Repairing a Frozen Air Conditioner

Does the air emitting from your supply registers unexpectedly seem not cold enough? Look at the indoor portion of your air conditioner. This component is housed within your furnace or air handler, if you use a heat pump. If there’s water dripping onto the floor, there may be ice on the evaporator coil. The AC coil in the unit might have frozen over. You’ll need to thaw it before it can cool your residence again.

Here’s the things you should do. If you can’t get the coil back to normal, Service Experts Heating, Air Conditioning & Plumbing is here to assist you with air conditioning repair in the U.S. that includes a 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 prevents cold refrigerant from flowing to the outdoor compressor, which could harm it and result in a costly repair.

Next, adjust the fan from “auto” to “on.” This creates hot airflow over the frosty 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 less than an hour or most of the day for the ice to melt, depending on the extent of the accumulation. While you’re waiting, watch the condensate pan below the AC unit. If the drain line is blocked, it can overflow as the ice melts, possibly creating water damage.

Step 2: Troubleshoot the Trouble

Poor airflow is a primary explanation for an AC to become frozen. Here’s how to troubleshoot the issue:

    • Look at the filter. Inadequate airflow through a dirty filter could be to blame. Check and change the filter monthly or immediately when you observe dust accumulation.
    • Open any closed supply vents. Your residence’s supply registers should remain open all the time. Closing vents decreases airflow over the evaporator coil, which could lead it to freeze.
    • Be on the lookout for obstructed return vents. These typically don’t use moveable louvers, but furniture, rugs or curtains can still cover them.
    • Insufficient refrigerant: While airflow restrictions are the most common culprit, your system may also not have enough refrigerant. Depending on its age, it may have Freon®. Insufficient refrigerant necessitates pro attention from a certified HVAC technician. H2: Step 3: Contact an HVAC Professional at Service Experts Heating, Air Conditioning & Plumbing

If low airflow doesn’t seem to be the trouble, then another problem is leading your AC freeze. If this is what’s going on, simply defrosting it won’t fix the problem. The evaporator coil will possibly keep freezing unless you fix the underlying symptom. Call an HVAC pro to address problems with your air conditioner, which might include:

    • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run out. Insufficient refrigerant signals a leak somewhere. Only a technician can find the leak, mend it, and recharge the system to the proper amount.
    • Dirty evaporator coil: If dirt builds up on the coil, air can’t reach it, and it’s likely to freeze.
    • Malfunctioning blower: A bad motor or unbalanced fan can stop airflow over the evaporator coil.
