3 Quick Ways to Repair a Frozen Air Conditioner

Does the air flowing from your supply registers suddenly seem not cold enough? Look at the indoor part of your air conditioner. This piece is housed within your furnace or air handler, if you rely on a heat pump. If there’s water dripping onto the floor, there may be ice on the evaporator coil. The AC coil inside the equipment might have frosted 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 frost-free, Church Services is here to assist you with air conditioning repair in Houston that includes a a 100% satisfaction guarantee.*

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

To get started—move the thermostat from “cool” to “off.” This stops chilly refrigerant from going to the outdoor compressor, which could hurt it and lead to an expensive repair.

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

It can take not more than an hour or the majority of the day for the ice to defrost, depending on the degree of the buildup. While you’re waiting, watch the condensate pan underneath the AC unit. If the drain line is clogged, it can spill over as the ice melts, possibly causing water damage.

Step 2: Troubleshoot the Situation

Poor airflow is a main reason for an AC to frost over. Here’s how to figure out the situation:

  • Exmaine the filter. Low airflow through a filthy filter could be the culprit. Look at and put in a new filter monthly or as soon as you notice dust accumulation.
  • Open any shut supply vents. Your home’s supply registers should stay open always. Shutting vents reduces airflow over the evaporator coil, which may result in it freezing.
  • Be on the lookout for blocked return vents. These typically don’t use adjustable louvers, but furniture, rugs or curtains can still cover them.
  • Not enough refrigerant: While airflow restrictions are the most typical culprit, your air conditioner might also have insufficient refrigerant. Depending on when it was installed, it may rely on Freon®. Not enough refrigerant requires skilled help from a certified HVAC specialist. H2: Step 3: Contact an HVAC Expert at Church Services

If poor airflow doesn’t feel like the trouble, then another issue is making your AC freeze. If this is what’s occurring, merely defrosting it won’t fix the issue. The evaporator coil will probably continually freeze unless you take care of the main problem. Get in touch with an HVAC technician to look for troubles with your air conditioner, which can include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run out. Low refrigerant indicates a leak somewhere. Only a tech can pinpoint the leak, mend it, and recharge the system to the correct amount.
  • Grimy evaporator coil: If dirt accumulates on the coil, air can’t reach it, and it’s likely to freeze.
  • Nonfunctional blower: A broken motor or unbalanced fan can halt airflow over the evaporator coil.
