3 Simple Steps to Repair a Frozen Air Conditioner

Does the air coming from your supply registers unexpectedly seem warm? Inspect the indoor portion of your air conditioner. This piece is situated in your furnace or air handler, if you use a heat pump. If there’s water dripping onto the floor, there might be ice on the evaporator coil. The AC coil within the equipment might have frozen over. You’ll need to defrost it before it can cool your home again.

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

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

To begin—move the thermostat from “cool” to “off.” This halts cold refrigerant from flowing to the outdoor compressor, which could harm it and result in a costly repair.

Then, switch the fan from “auto” to “on.” This makes hot airflow over the frosty coils to help them melt faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.

It might take not more than an hour or the better part of a day for the ice to defrost, depending on the level of the ice. While you’re waiting, watch the condensate pan below the AC unit. If the drain line is blocked, it could spill over as the ice melts, likely resulting in water damage.

Step 2: Pinpoint the Problem

Not enough airflow is a prime reason for an AC to become frozen. Here’s how to troubleshoot the problem:

  • Inspect the filter. Low airflow through a clogged filter could be the issue. Check and replace the filter monthly or once you observe a layer of dust.
  • Open any shut supply vents. Your residence’s supply registers should remain open always. Sealing vents reduces airflow over the evaporator coil, which might result in it freezing.
  • Check for obstructed return vents. These typically don’t have shiftable louvers, but furniture, rugs or curtains can still obstruct them.
  • Not enough refrigerant: While airflow restrictions are the most typical cause, your system could also not have enough refrigerant. Depending on how old it is, it may use Freon® or Puron®. Low refrigerant necessitates skilled attention from a certified HVAC technician. H2: Step 3: Contact an HVAC Technician at Service Experts Heating & Air Conditioning

If inadequate airflow doesn’t appear to be the trouble, then something else is making your AC frost over. If this is what’s going on, simply defrosting it won’t repair the trouble. The evaporator coil will probably continually freeze unless you take care of the root cause. Call an HVAC tech to check for troubles with your air conditioner, which may include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Insufficient refrigerant indicates a leak somewhere. Only a technician can pinpoint the leak, repair it, and recharge the air conditioning to the correct amount.
  • Dirty evaporator coil: If grime collects on the coil, air can’t reach it, and it’s likely to freeze.
  • Malfunctioning blower: A bad motor or unbalanced fan could stop airflow over the evaporator coil.
