Repair Your Frozen Air Conditioner with These 3 Simple Tips

Does the air coming from your supply registers suddenly seem not cold enough? Check the indoor component of your air conditioner. This part is located within your furnace or air handler, if you use a heat pump. If there’s water seeping onto the floor, there may be frost on the evaporator coil. The AC coil within the system could 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 Service Experts 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 begin—move the thermostat from “cool” to “off.” This halts chilled refrigerant from flowing to the outdoor compressor, which could harm it and lead to a costly repair.

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

It may 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 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 Problem

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

  • Exmaine the filter. Poor airflow through a filthy filter could be the issue. Inspect and replace the filter monthly or immediately when you notice dust accumulation.
  • Open any shut supply vents. Your residence’s supply registers should remain open always. Closing vents reduces airflow over the evaporator coil, which may result in it freezing.
  • Look for covered return vents. These typically don’t use shiftable louvers, but furniture, rugs or curtains can still block them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent cause, your air conditioner may also be low on refrigerant. Depending on when it was replaced, it may use Freon® or Puron®. Not enough refrigerant calls for skilled support from a certified HVAC technician.

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 letting it melt won’t fix the trouble. The evaporator coil will probably continually freeze unless you repair the root symptom. Get in touch with an HVAC technician to check for problems with your air conditioner, which may include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run out. Low refrigerant means there’s a leak somewhere. Only a professional can find the leak, fix it, and recharge the system to the proper amount.
  • Filthy evaporator coil: If dust collects on the coil, air can’t get to it, and it’s likely to freeze.
  • Nonfunctional blower: A faulty motor or unbalanced fan may stop airflow over the evaporator coil.
