Repair Your Frozen Air Conditioner with These 3 Easy Tips

Does the air coming from your supply registers abruptly appear not cold enough? Check the indoor component of your air conditioner. This component is housed inside 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 equipment may have frozen. 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 back to normal, Service Experts Heating & Air Conditioning is here to assist you with air conditioning repair in Gainesville upheld by a 100% satisfaction guarantee.*

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

First things first—switch the thermostat from “cool” to “off.” This stops chilled refrigerant from moving to the outdoor compressor, which could damage it and cause a pricey repair.

After that, switch the fan from “auto” to “on.” This makes hot airflow over the frosty coils to force them to thaw faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It may take under an hour or most of the day for the ice to thaw, depending on the degree of the accumulation. While you’re waiting, check the condensate pan below the AC unit. If the drain line is blocked, it may cause a mess as the ice melts, potentially resulting in water damage.

Step 2: Troubleshoot the Situation

Poor airflow is a prime reason for an AC to freeze up. Here’s how to get to the bottom of the issue:

  • Check the filter. Poor airflow through a dirty filter could be the issue. Check and change the filter once a month or immediately when you see dust accumulation.
  • Open any shut supply vents. Your house’s supply registers should stay open all the time. Sealing vents limits airflow over the evaporator coil, which could cause it to freeze.
  • Look for obstructed return vents. These often don’t come with adjustable louvers, but furniture, rugs or curtains can still obstruct them.
  • Not enough refrigerant: While airflow restrictions are the most typical cause, your system might also not have enough refrigerant. Depending on when it was installed, it may use Freon® or Puron®. Low refrigerant requires professional assistance from a certified HVAC tech. H2: Step 3: Call an HVAC Expert at Service Experts Heating & Air Conditioning

If insufficient airflow doesn’t feel like the problem, then another problem is making your AC frost over. If this is what’s occurring, merely thawing it out won’t fix the trouble. The evaporator coil will possibly freeze again unless you repair the root cause. Call an HVAC technician to check for troubles with your air conditioner, which may include:

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t get used up. Low refrigerant indicates a leak somewhere. Only a technician can find the leak, fix it, and recharge the system to the proper amount.
  • Dirty evaporator coil: If dirt accumulates on the coil, air can’t get to it, and it’s likely to freeze.
  • Nonfunctional blower: A faulty motor or unbalanced fan might stop airflow over the evaporator coil.
