3 Simple Steps for Repairing a Frozen Air Conditioner

Does the air coming from your supply registers suddenly appear hot? Check the indoor component of your air conditioner. This part is situated within your furnace or air handler, if you use a heat pump. If there’s water seeping onto the floor, there may be crystals on the evaporator coil. The AC coil within the system might have frozen over. You’ll need to melt it before it can cool your house again.

Here’s the steps you should take. If you can’t get the coil frost-free, Roy Inch & Sons Home Services by Enercare is here to help with air conditioning repair in London backed by a 100% satisfaction guarantee.*

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

To get started—switch the thermostat from “cool” to “off.” This halts chilled refrigerant from moving to the outdoor compressor, which could hurt it and lead to a costly repair.

Then, switch the fan from “auto” to “on.” This creates warm airflow over the frozen coils to force them to thaw faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.

It could take under an hour or the better part of a day for the ice to melt, depending on the level of the ice. While you’re waiting, check the condensate pan underneath the AC unit. If the drain line is blocked, it might overflow as the ice melts, likely resulting in water damage.

Step 2: Troubleshoot the Situation

Insufficient airflow is a main explanation for an AC to become frozen. Here’s how to troubleshoot the problem:

  • Exmaine the filter. Low airflow through a filthy filter could be the issue. Look at and put in a new filter monthly or immediately when you observe dust accumulation.
  • Open any sealed supply vents. Your house’s supply registers should remain open always. Closing vents reduces airflow over the evaporator coil, which may lead it to freeze.
  • Be on the lookout for obstructed return vents. These typically don’t come with shiftable louvers, but furniture, rugs or curtains can still block them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent cause, your air conditioning may also be low on refrigerant. Depending on when it was replaced, it may use Freon®. Insufficient refrigerant necessitates pro assistance from a certified HVAC technician. H2: Step 3: Get in Touch with an HVAC Expert at Roy Inch & Sons Home Services by Enercare

If inadequate airflow doesn’t appear to be the issue, then something else is making your AC freeze. If this is what’s occurring, merely defrosting it won’t fix the trouble. The evaporator coil will possibly continually freeze unless you repair the root symptom. Contact an HVAC professional to check for problems with your air conditioner, which could include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run low. Low refrigerant means there’s a leak somewhere. Only a tech can find the leak, fix it, and recharge the system to the proper concentration.
  • Grimy evaporator coil: If dust accumulates on the coil, air can’t flow over it, and it’s apt to freeze.
  • Nonfunctional blower: A faulty motor or unbalanced fan could stop airflow over the evaporator coil.
