3 Fast Ways to Restore a Frozen Air Conditioner

Does the air flowing from your supply registers unexpectedly feel warm? Look at the indoor portion of your air conditioner. This piece is located in your furnace or air handler, if you rely on a heat pump. If there’s water leaking onto the floor, there may be ice on the evaporator coil. The AC coil inside the system may have frozen over. You’ll need to thaw it before it can cool your residence again.

Here’s the steps you should take. If you can’t get the coil back to normal, Winnipeg Supply Service Experts is here to help with air conditioning repair in Winnipeg that includes a a 100% satisfaction guarantee.*

Step 1: Switch the Air Conditioning Off and the Blower On

To begin—set the thermostat from “cool” to “off.” This stops chilly refrigerant from going to the outdoor compressor, which could harm it and lead to a pricey repair.

Then, switch the fan from “auto” to “on.” This produces hot airflow over the frosty coils to help them thaw faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.

It can take under an hour or the majority of the day for the ice to thaw, depending on the extent of the buildup. While you’re waiting, keep an eye on the condensate pan below the AC unit. If the drain line is clogged, it might overflow as the ice melts, likely resulting in water damage.

Step 2: Troubleshoot the Problem

Poor airflow is a leading cause for an AC to become frozen. Here’s how to get to the bottom of the problem:

  • Exmaine the filter. Low airflow through a clogged filter could be to blame. Check and change the filter monthly or immediately when you see dust accumulation.
  • Open any closed supply vents. Your home’s supply registers should stay open all the time. Sealing vents reduces airflow over the evaporator coil, which can result in it freezing.
  • Be on the lookout for obstructed return vents. These usually don’t use adjustable louvers, but furniture, rugs or curtains can still cover them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent cause, your air conditioner could also have insufficient refrigerant. Depending on how old it is, it may use Freon®. Low refrigerant calls for professional attention from a certified HVAC technician. H2: Step 3: Get in Touch with an HVAC Technician at Winnipeg Supply Service Experts

If low airflow doesn’t appear to be the problem, then something else is causing your AC freeze. If this is what’s going on, merely letting it melt won’t repair the problem. The evaporator coil will probably continually freeze unless you take care of the root cause. Get in touch with an HVAC specialist to check for problems with your air conditioner, which might include:

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run low. Not enough refrigerant is a sign of a leak somewhere. Only a tech can find the leak, mend it, and recharge the air conditioning to the correct level.
  • Grimy evaporator coil: If grime builds up on the coil, air can’t get to it, and it’s apt to freeze.
  • Malfunctioning blower: A defective motor or unbalanced fan can halt airflow over the evaporator coil.
