Clear The Dust From The Filter
Your air conditioners filter resembles a fine screen enclosed in a plastic frame. It collects trash and air particles to keep them from flowing throughout the area.
The filter is an essential component of the air conditioner, but the dust accumulated on it can supply an ideal environment for mold to thrive.
The filter is always located just behind the front grill and is usually reusable. Control your hand-held vacuum or vacuum hose along the filter to eliminate dust . Alternatively, you can rinse the filter under running water to remove the dust .
Can Black Mold Grow In Window Air Conditioners
Air conditioners and HVAC ducts, in most cases, are not conducive to mold growth. Mold does not find a food supply in sheet metal ducts and styrofoam channels inside window units. However, dust frequently gathers in these areas, allowing mold to form.
Mold needs two things to thrive: wetness and an organic food source. Moisture might be caused by high humidity or an improperly cleaned-up leak or spill. Condenser and evaporator coils are the primary sources of condensation and, as such, have the potential for water leakage if not adequately drained. On the other hand, if there is adequate food, the mold can feed on the surface it is growing on, such as wood or carpet, or on organic particles found in dust.

How Do I Clean Mold Out Of A Window Air Conditioner
- Rosalie M on May 30, 2013It was always my understanding that Clorox removed mold. You should try a solution of warm water and bleach and wipe the air conditioner down with that. If the solution didn’t work, I would try straight Clorox. It won’t hurt it.
- Miles Enterprises Inc. on May 31, 2013i agree with Rosalie M i would put a ltle bleach with a glass cleaner so the unit does not smell like bleach .
- Kathy Driscoll on Jul 26, 2014@Miles Enterprises Inc. don’t mix chemicals- the odor can make you sick- especially bleach and ammonia- in the glass cleaner.

How To Clean A Window Ac Unit Without Removing It
The safest way to thoroughly clean your window air conditioner is to remove it from the window, but that’s not always possible. Fortunately, there are some cleaning tasks you can do with the AC installed.
You can clean the front evaporator coils by removing the filter and front grill of your window AC. Use compressed air to blow dust and debris from the fins. A soft bristle brush or fin comb will also work as long as you are gentle and don’t bend the fins.
If you’re able to access the AC from the outside, like, for example, if it’s installed on the first floor of a building, then you can clean the condenser coil. You can use the dry method described above or clean with water using a spray bottle or hose with a nozzle attachment. If you use water, make sure there is no power running to the AC and that the water will drain outside. If your AC is angled correctly, the water should drain outside.

Take Off The Grill Of The Air Conditioner Unit And Take Out The Filter
Filters should be changed every 1 to 3 months in a large HVAC unit if there is a smoker in the home. In a small unit, you want to check it every 30 days to make sure it is not jammed or full of dirt.
You may be able to let it soak in the bucket of soapy water and then let it air dry. On the other hand, it may be time for a replacement. If you need to replace it, refer to the manual for the correct size and be sure you have the model number. There are various sizes and types out there and you need to get the correct one.
Also, remember the air filter keeps the air clean so you want it as clean as possible. It may not need to be changed that much in a small window unit but always a good idea to check. Some air conditioner units have a filter rest button that will let you know when it is time to replace the filter as well.

Use Fan Mode To Dry The Inside Of The Ac
Some window ACs have a fan option. However, the compressor wont turn on to transfer heat, so the fan will blow. Once youve cooled down the room, turn on fan mode.
This will dry out your AC unit, which could cause it to fail. And since the EPA reminds us that moisture management is the key to mold control, you should probably take care of that before it gets too bad.
What You Need To Know About Getting Rid Of Mold In A Window Air Conditioner
If you think your air conditioner might have mold in it, its important to act quickly.
According to the CDC, exposure to moldy environments can cause a variety of health effects. Similarly, the EPA says mold spores produce allergens and irritants, and touching or inhaling them can irritate the eyes, skin, nose, throat, and lungs. Inhaling or touching mold or mold spores can cause allergic reactions in sensitive individuals.
Mold can even cause asthma attacks in people with asthma who are allergic to mold!
Unfortunately, under some circumstances there can be so much mold on the unit that its nearly impossible to completely remove all of it. In these situations, a new air conditioning unit is needed because if the mold is not entirely removed, it will grow back over time.

Helpful Tips To Prevent Mold Growing In Ac
The best way to clean mold from your AC unit is to prevent it from growing there in the first place. Preventing mold in your AC involves actions you should take to prevent mold from your entire home:

- Make sure the AC drains run properly.Your AC unit produces condensation, and if it cant get out of the air conditioner, that moisture will engender a lovely environment for mold.
- Regularly run the unit on its fan mode.This allows air to circulate without generating condensation that collects when the compressor is in use, which helps dry the interior.
- Use a cover. Once cooler weather comes around, and your AC unit will be beaded into hibernation mode, cover it to keep out moisture, leaves, or other contaminants.

Signs Of Mold Spores In Your Air Conditioner
How will I know that there is mold in my AC unit? The scary thing about all this is that their presence may be subtle for a long time. This means that you can stay with it for ages without noticing it, which is dangerous.
However, if you are careful, you will realize that the signs are noticeable. A key sign is the presence of a mildew smell. It smells like a stuffy attic, old and musty socks, or an earthy smell.
If you are noticing this smell how do you know it is from your air conditioner? How do you know it is not from the carpet or woody furniture?
When it is in your AC unit, you will notice the smell increases when the Air Conditioner system is on. When you switch it off, it will not be as noticeable.
Here are signs to watch out for when you switch on your AC unit:
- The mold-like smell is filling the air.

- Black dust accumulating around the vents,

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.

How Bad Is The Growth Of Mold For Our Health
According to the CDC, mold can emit spores that we unintentionally inhale. This can cause nasal stuffiness, throat irritation, coughing or wheezing, eye discomfort, etc. People with weakened immune systems or persistent lung diseases may get severe infections in their lungs.
Even my dust allergy got out of hand because of mold and I experienced skin irritation. Thankfully as soon as I was aware of its growth, I wiped it clean right away.
Though mold in the air conditioner is said to be not that dangerous, it can become worse when the unit is turned on for the whole day. Imagine invisible mold spores spreading throughout your room along with the cool air? You will never be able to figure it out but will start suffering from health issues.
Detergent And Baking Soda
