Get Your Frozen Air Conditioner Working Again with These 3 Fast Tips

Does the air coming from your supply registers abruptly appear warm? Inspect the indoor part of your air conditioner. This piece is situated inside your furnace or air handler, if you rely on a heat pump. If there’s water leaking onto the floor, there might be frost on the evaporator coil. The AC coil in the system could have frozen over. You’ll need to melt it before it can cool your home again.

Here’s the things you should do. If you can’t get the coil defrosted, Abbey Air Service Experts is here to assist you with air conditioning repair in Oakville backed by a 100% satisfaction guarantee.*

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

To begin—set the thermostat from “cool” to “off.” This stops cold refrigerant from flowing to the outdoor compressor, which could damage it and cause a pricey repair.

Next, adjust 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 begin a cooling cycle.

It can take under an hour or the better part of a day for the ice to defrost, depending on the degree of the buildup. While you’re waiting, check the condensate pan underneath the AC unit. If the drain line is obstructed, it might create a mess as the ice melts, possibly creating water damage.

Step 2: Pinpoint the Situation

Low airflow is a primary reason for an AC to freeze up. Here’s how to troubleshoot the situation:

  • Exmaine the filter. Poor airflow through a clogged filter could be to blame. Look at and change the filter each month or immediately when you notice dust buildup.
  • Open any shut supply vents. Your house’s supply registers should be open all the time. Sealing vents limits airflow over the evaporator coil, which may lead it to freeze.
  • Be on the lookout for obstructed return vents. These typically don’t have moveable louvers, but furniture, rugs or curtains can still cover them.
  • Low refrigerant: While airflow restrictions are the most typical cause, your air conditioning may also have insufficient refrigerant. Depending on when it was installed, it may have Freon® or Puron®. Insufficient refrigerant requires professional assistance from a certified HVAC specialist. H2: Step 3: Contact an HVAC Professional at Abbey Air Service Experts

If insufficient airflow doesn’t seem to be the problem, then something else is leading your AC freeze up. If this is what’s going on, just thawing it out won’t take care of the issue. The evaporator coil will possibly keep freezing unless you repair the root problem. Get in touch with an HVAC pro to check for issues with your air conditioner, which can include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run out. Low refrigerant means there’s a leak somewhere. Only a professional can find the leak, repair it, and recharge the air conditioning to the proper concentration.
  • Grimy evaporator coil: If dirt accumulates on the coil, air can’t flow over it, and it’s liable to freeze.
  • Broken blower: A faulty motor or unbalanced fan could stop airflow over the evaporator coil.
