3 Easy Ways to Fix a Frozen Air Conditioner

Does the air flowing from your supply registers suddenly appear warm? Inspect the indoor portion of your air conditioner. This piece is housed inside your furnace or air handler, if you rely on a heat pump. If there’s water dripping onto the floor, there might be crystals on the evaporator coil. The AC coil inside the equipment may have frozen. You’ll need to defrost it before it can cool your house again.

Here’s what to do. If you can’t get the coil frost-free, Roland J. Down Service Experts is here to assist you with air conditioning repair in Albany 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 prevents chilled refrigerant from flowing to the outdoor compressor, which could harm it and lead to a pricey repair.

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

It could take not more than an hour or the better part of a day for the ice to melt, depending on the amount of the ice. While you’re waiting, check the condensate pan underneath the AC unit. If the drain line is clogged, it can create a mess as the ice melts, potentially creating water damage.

Step 2: Troubleshoot the Issue

Poor airflow is a prime reason for an AC to freeze up. Here’s how to figure out the issue:

  • Inspect the filter. Inadequate airflow through a dusty filter could be to blame. Look at and replace the filter each month or once you see dust accumulation.
  • Open any closed supply vents. Your residence’s supply registers should remain open constantly. Shutting vents decreases airflow over the evaporator coil, which can lead it to freeze.
  • Look for obstructed return vents. These typically don’t use moveable louvers, but furniture, rugs or curtains can still cover them.
  • Not enough refrigerant: While airflow restrictions are the most typical culprit, your air conditioner might also be low on refrigerant. Depending on when it was replaced, it may use Freon®. Low refrigerant necessitates professional assistance from a certified HVAC specialist. H2: Step 3: Get in Touch with an HVAC Specialist at Roland J. Down Service Experts

If inadequate airflow doesn’t appear to be the trouble, then another issue is leading your AC frost over. If this is what’s happening, just letting it melt won’t repair the problem. The evaporator coil will probably keep freezing unless you take care of the underlying cause. Get in touch with an HVAC technician to check for troubles with your air conditioner, which can include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Low refrigerant is a sign of a leak somewhere. Only a specialist can pinpoint the leak, mend it, and recharge the air conditioner to the proper concentration.
  • Dirty evaporator coil: If dirt builds up on the coil, air can’t flow over it, and it’s likely to freeze.
  • Nonfunctional blower: A bad motor or unbalanced fan could stop airflow over the evaporator coil.
