Fix Your Frozen Air Conditioner with These 3 Quick Tips

Does the air coming from your supply registers suddenly feel warm? Look at the indoor part of your air conditioner. This component is housed in your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there could be frost on the evaporator coil. The AC coil in the system may have frosted over. You’ll need to thaw it before it can cool your house again.

Here’s what to do. If you can’t get the coil frost-free, Service Experts Heating & Air Conditioning is here to help with air conditioning repair in Girard upheld 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 damage it and cause a costly repair.

After that, switch the fan from “auto” to “on.” This makes heated airflow over the frozen coils to force them to melt faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.

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

Step 2: Pinpoint the Situation

Not enough airflow is a chief reason for an AC to become frozen. Here’s how to troubleshoot the issue:

  • Look at the filter. Poor airflow through a filthy filter could be to blame. Check and replace the filter each month or once you notice dust accumulation.
  • Open any shut supply vents. Your home’s supply registers should remain open all the time. Shutting vents limits airflow over the evaporator coil, which could cause it to freeze.
  • Look for obstructed return vents. These typically don’t have moveable louvers, but furniture, rugs or curtains can still obstruct them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent culprit, your system may also have insufficient refrigerant. Depending on its age, it may have Freon®. Insufficient refrigerant necessitates professional assistance from a certified HVAC tech. H2: Step 3: Call an HVAC Expert at Service Experts Heating & Air Conditioning

If inadequate airflow doesn’t feel like the problem, then another problem is causing your AC frost over. If this is what’s happening, simply thawing it out won’t fix the issue. The evaporator coil will possibly keep freezing unless you fix the main issue. Call an HVAC technician to check for troubles with your air conditioner, which may include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Low refrigerant indicates a leak somewhere. Only a technician can pinpoint the leak, repair it, and recharge the air conditioning to the correct amount.
  • Filthy evaporator coil: If dust accumulates on the coil, air can’t flow over it, and it’s apt to freeze.
  • Malfunctioning blower: A broken motor or unbalanced fan can prevent airflow over the evaporator coil.
