How to Clean a Dirty Moldy Window Air Conditioner

Humidity is a significant driver of mold growth- if the humidity in the room is high, mold growth will be accelerated.

To prevent a moldy mess, youll need to keep the humidity level in check. Not every window AC unit comes with a humidity control, but many of them do.

Look at your AC unit closely and see if there is a humidity setting. If your AC is equipped with humidity control, turn it on and set the humidity level to 30-50%.

This humidity level is perfect, as it will keep you comfortable without encouraging mold growth.

If you havent yet bought an AC unit, make sure that you purchase a model that allows you to control the humidity setting.

How Mold Grows In Air Conditioners

Mold spores are everywhere. Unfortunately, it is impossible to get rid of all the mold spores in your house, and even if you did, more would come in every time you opened a door or window. When spores grow into mold, more spores are released, and these higher concentrations of spores are what cause the health problems associated with mold. Thus, the key is to prevent the mold from growing in the first place.

Mold needs two things in order to grow: moisture and an organic food source. Moisture can come from high humidity, or a leak or spill that is not cleaned up properly. Condenser and evaporator coils are the main contributors to condensation, and therefore have potential for water leakage if not properly drained. The food source can be the surface the mold is growing on, like wood or carpet, or organic particles found in dust, if there is enough of it.

Under most circumstances, air conditioners and HVAC ducts are not hospitable places for mold to grow. Sheet metal ducts and styrofoam channels inside window units do not offer mold a food source. However, dust often collects in these places, which can allow mold to grow.

    Prevent Future Mold Growth

    There are several things you can do to stop mold from growing in the first place after you have cleaned your unit. First, you should leave your AC on at all times. Your AC does more than cool down the air. It also conditions the air by removing moisture, which also makes your home more comfortable. Leave your AC on a continuous cycle.

    Itâs also highly recommended to get on a routine maintenance schedule. You should hire a professional to inspect your unit at least once a year to make sure everything works as it should. A Day & Night Air professional will also tell you if you have the early signs of mold growing. They will conduct deep maintenance and clean your unit to prevent mold from developing initially. This will save you a lot of hassle. Although you are certainly capable of cleaning a unit on your own, it helps to have a professional do it to stop the problem from coming back.

    Additionally, you need to identify and stop any leaks as soon as they form. Mold requires moisture to develop, so a leak in the system will lead to mold growth quickly. Mold also needs stale air, so if you turn off your AC often, then mold has everything it needs to thrive.

    Cleaning Without Removing A Window Air Conditioner

    Is this mold in my window ac? If so, what should I do ...

    It can be hard to clean a window air conditioner without disconnecting it from the wall as you need a considerable amount of water. However, it is possible with a little more effort.

    Before starting the job, you should put some buckets under your AC. Then, take off the screws of the frontal case or mask and take out the filter.

    Afterward, you need to spray the device and wipe it with the dry cloth at the same time. Repeat the process until you see the frontal and inner parts are entirely clean. Dont forget to spray the filter and rinse it, as well. It is an excellent idea to do so in your bath or sink.

    The next step is to go outside and spray the AC without removing the cover. Do it wherever you see the hole. Leave the agent and water to soak all the parts of the device for approximately 15 minutes.

    Then rinse the device with water from the hose or bucket. Make sure not to pour a large amount of water immediately. It is better to use less water over a more extended period. While doing so, you will see the dirt comes from the bottom holes of the outside unit.

    You will know a window air conditioner is clean once the water coming out becomes clean. If needed, you can repeat the soaking part, but always rinse the detergent or bleach afterward.

    Once you have finished with the cleaning, you should leave all the parts to dry for at least 2 to 4 hours. After putting back all the pieces together, your seasonal cleaning is finished.

    How To Prevent Mold In Window Air Conditioners

    Now that the black mold in the air conditioner is gone, keep it away with these tips to deprive it of food and water!

    1). Remove Dust: Mold feeds on dust and dirt. If you dust or vacuum away dust, dirt, pollen and other organic materials, you can starve any mold that begins growing. Using compressed air to blow dust out the back of the AC might help too. Some people cover the inside part of the AC with a towel when not in use to prevent it from getting dusty.

    2). Use Fan Mode to Dry the Interior of the AC: Most window air conditioners have a Fan setting. The compressor wont come on to remove heat, but the fan will blow. After youve cooled the room, turn on Fan Mode.

    This will dry out the interior of the air conditioner and as the EPA reminds us, moisture control is the key to mold control.

    3). Clean your Window AC Once or Twice During the Cooling Season: If you live in a hot climate, especially one that is humid too, clean your AC at least twice during the cooling season. Inspect it monthly for mold.

    If your AC doesnt get heavy use, then cleaning it once during the season should be sufficient unless you or someone in your household is especially sensitive to mold.

  • rinse
  • air dry
  • Use a wet/dry vac to remove all debris from the interior of the unit
  • Deep clean all affected surfaces using a mixture of 1 parts bleach to 10 parts water, adding a spoonful of detergent for extra penetration.
  • Allow at least 10 minutes for the bleach to kill off any last remnants of mold
  • Hose or otherwise rinse off the unit, but avoid soaking the electrical components
  • Allow to dry
  • Reinstall the filter, reassemble and reinstall
  • If youre intimidated by the above work, remember: hiring a mold removal expert is always a safe and sure-fire way of getting mold eradicated.

    2).Check the owners manual to see how to discharge the Capacitor correctly. The Capacitor is the device that keeps an extra charge to kick-start the motor. This step in necessary because it will make sure there are no electrical charges left on it before you start the cleaning process.

    3).Next, clean the outside cover by wiping it down with a wet cloth. Be sure to use a good dirt and grim cleaner so that when you open the cover no loose particles fall inside.

    4). Remove the cover from the front of it by either unsnapping it with your hands or removing the screws/plastic hooks that hold the cover in place. Use caution while handling the metal pieces, the edges can be sharp.

    5). If the filter to your unit is reusable, remove it and clean it with hot, soapy water until it is nice and clean. To remove all the dust and particle buildup, use a soft brush and gently remove everything. Set the filter in an area where it can dry thoroughly before you put in back the A/C. Putting a damp filter back in will only attract more dirt and mold.

    6). If it has a disposable filter, manufacturers recommend changing it monthly to help keep mold at bay.
