Simple Steps for Repairing a Frozen Air Conditioner

Does the air emitting from your supply registers abruptly appear warm? Check the indoor part of your air conditioner. This piece is situated in your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there may be crystals on the evaporator coil. The AC coil inside the system may have frozen. You’ll need to defrost it before it can cool your house again.

Here’s the steps you should take. 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—switch the thermostat from “cool” to “off.” This halts chilly refrigerant from going to the outdoor compressor, which could harm it and result in an expensive repair.

Then, move the fan from “auto” to “on.” This produces warm 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 begin a cooling cycle.

It can take less than an hour or the majority of the day for the ice to thaw, depending on the amount of the accumulation. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is obstructed, it might spill over as the ice melts, potentially causing water damage.

Step 2: Diagnose the Trouble

Not enough airflow is a prime cause for an AC to frost over. Here’s how to get to the bottom of the situation:

    • Inspect the filter. Inadequate airflow through a filthy filter could be to blame. Look at and change the filter each month or once you notice a layer of dust.
    • Open any shut supply vents. Your home’s supply registers should remain open always. Closing vents reduces airflow over the evaporator coil, which may lead it to freeze.
    • Check for obstructed return vents. These usually don’t use shiftable louvers, but furniture, rugs or curtains can still block them.
    • Not enough refrigerant: While airflow restrictions are the most common culprit, your system might also have insufficient refrigerant. Depending on its age, it may use Freon®. Not enough refrigerant requires skilled attention from a certified HVAC tech. H2: Step 3: Contact an HVAC Tech at Service Experts Heating, Air Conditioning & Plumbing

If poor airflow doesn’t seem to be the issue, then something else is making your AC frost over. If this is the case, merely defrosting it won’t repair the issue. The evaporator coil will probably freeze again unless you fix the underlying cause. Get in touch with an HVAC technician to address problems with your air conditioner, which might include:

    • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run out. Insufficient refrigerant means there’s a leak somewhere. Only a tech can find the leak, repair it, and recharge the air conditioning to the proper amount.
    • 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 could halt airflow over the evaporator coil.
