How To Clean Mold From Air Conditioner Coils 5 Easy Steps

An essential part of an ACs maintenance is keeping its coils clean, so you might want to know how to clean mold from air conditioner coils. Whats even important is keeping them from growing even more.

If the coils are not clean with grime and debris, the airflow passing through the coils will be limited. In such a case, the air conditioning system will have to work harder to cool the room.

In some cases, it will even burn itself after working that much. Debris, dust, and dirt are also the perfect breeding ground for mildew, mold, and bacteria to grow. This will cause health problems as it increases the spores of mold circulating through the air in your house.

Not only that, but it will also cause your electric bills to increase. A biofilm will start to develop on the coils if the air is limited and mold build-up. This will create a barrier inside the coils. As a result, the unit will not be exchanging heat as it normally does.

With that being said, it is important to clean up those mold from the coils.

  • Its A Wrap!
  • How To Prevent Mold In The Air Conditioner

    Keeping mold out of your air conditioner is the best way to ensure you have clean air circulating in your home, and there are several steps to do this.

    HEPA filters: All air conditioner units come fitted with air filters. The problem with these filters is that they only block out the larger particles and they are there to protect the components of the unit and not your health. Fortunately, there are HEPA filters available for these systems, which will prevent microscopic mold spores from entering the air conditioner and, ultimately, your home.

    UV filters: Most new air conditioners available for purchase today comes with a bacteria-killing UV light filter already fitted. In many cases, a UV filter can be purchased separately and installed on the current AC unit. This filter kills up to 99% of all viruses, bacteria, and mold spores without putting any additional strain on your air conditioner. Read more about the best mold-proof UV filters for air conditioners here.

    Yearly maintenance: Its recommended to have a professional come in annually to thoroughly clean and do maintenance on your air conditioner. Air filters and drain pans need to be cleaned and replaced, while air ducts should be cleaned and dried.

    Cleaning Without Removing A Window Air Conditioner

    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.

    The Dangers Of Mold In Your Air Conditioner

    If mold is growing in your house, it can release spores that can be easily inhaled. According to the CDC, molds can cause nasal stuffiness, throat irritation, coughing or wheezing, eye irritation, or, in some cases, skin irritation. People with mold allergies may have more severe reactions. Immune-compromised people and people with chronic lung illnesses, such as obstructive lung disease, may get serious infections in their lungs when they are exposed to mold.

    Mold growing in an AC unit is not necessarily more dangerous than mold growing elsewhere in your house. However, the function of an air conditioner is to spread cool air throughout a room, and the purpose of the HVAC ducts is to distribute air throughout the house. If they become contaminated with mold, they will efficiently distribute mold spores across an entire room or the entire house. If the concentration of mold spores is high enough, you will have a mold problem everywhere, rather than in just one location, and you will be inhaling mold spores in every room, even while you sleep.

    Tools and Equipment for Cleaning the Coils

    Before you can start cleaning mold and other debris from the air conditioner coils, you need to ensure that you have the right tools and equipment. Depending on the type of AC unit, you may need a screwdriver to remove access panels, along with these items:

    • Disinfectant cleaning spray
    • Trash bags
    • Soft bristle brush

    You may also need a wet/dry vac to vacuum any standing water and other debris before cleaning the coils.

    There are different types of cleaning sprays available that are designed specifically for cleaning mold and bacteria from metal parts. The best cleaners are labelled for HVAC use and can help kill mold, mildew, and bacteria.

    The cleaners are typically available as a liquid or a foam. The liquid cleaners will require you to rinse the parts clean afterward using a wet rag. The foam cleaners do not require you to rinse. However, you will need to wipe the foam clean after allowing it to set.

    When cleaning the coils, you should also consider replacing the AC filter. If mold is present on the coils, there are likely mold spores in the filter.

    Locate the Coils and Remove Access Panels

    After gathering the necessary tools and equipment, you should be ready to clean the mold from the coils. First, turn off the air conditioner and disconnect the power.

    Air conditioner vents can be breeding grounds for black mold. Condensation forms in the coils and ducts as cool air circulates through the system, creating a habitat for moisture-loving mold. Black mold can cause severe respiratory symptoms, particularly in people who are allergic to mold. After you clean your air conditioner vents, inspect walls and insulation to find the source of the black mold infestation.

  • Wear long sleeves and pants and put on a high-efficiency dust mask to protect yourself from black mold spores. Make sure all household members with mold allergies or respiratory problems are out of the house before you begin to clean the air conditioner vents.

  • Remove the vent cover of a window air conditioner by unscrewing the screws with a screwdriver or pressing in on pressure clips. Place the vent cover in a basin or tub, sprinkle with laundry detergent and add enough water to cover the vent cover. After 15 minutes, rinse and allow the filter and vent cover to air-dry.

  • Remove dust from the inside of the air conditioner, as the dust in the moist environment allows mold to thrive.

  • Spray the blades and duct opening with water to prevent dry mold from escaping into the air. Wipe the blades and duct opening as thoroughly as possible with soapy water. Mold spores are microscopic and not visible to the naked eye, so clean surfaces even if you do not see mold.
