How Does Mold Occur

Get Rid Of Ugly (Gross) Mold And Mildew Fast

Mold needs a damp, humid environment to breed. That means water is part of molds equation. Remove the water, and mold cant live. According to the U.S. Environmental Protection Agency , mold already exists in all homes, even in your Midland, Michigan home. But in most cases, it exists on such a small scale that its not noticeable or a health risk. Its when that damp, humid environment is introduced that mold grows.

This mold-ideal environment can be introduced because of an unknown or ignored leak somewhere in your home or high humidity. Air with over 70 percent humidity is a definite breeding ground for mold. Once the mold begins to grow, the spores can travel through your homes air causing allergen issues. A small leak in your HVAC system or ignored air conditioner drains and pans, evaporator coils, or air handlers could very well be an origin of mold.

Almost every air conditioner should have a fan mode that you must regularly to avoid moisture building up inside the AC units.

  • Clean Your Window AC Once or Twice During the Cooling Season

You can opt for HEPA filters on your unit, as they can hold back smaller particles as well.

  • UV filters

For your home to be safe from mold, you might also want to invest in a UV filter. These filters can kill 99% of bacteria and viruses, which means that mold doesnt have a chance.

The Dangers Of Mold In Your Air Conditioner

How to Clean a Dirty Moldy Window 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, which is what makes mold in HVAC systems so concerning. 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.

Allow The Ac Unit To Air Dry

Allow the AC enough time to air dry. This could take as long as 24 hours. Ensure that the unit, grille and filter are completely dry before using the system again.

During the 24 hours, you can seek other ways to cool your room, but do not use your air conditioning unit. Remember, moisture creates a good breeding ground for mold.

  • Wear personal protection: this includes latex gloves, safety goggles, protective clothing , and a respirator with cartridges with a N-95 rating or a N-95 rated breathing mask.

  • Clean all vent covers: use vinegar to wipe both sides of any register and cold air return covers. When finished, allow the surfaces to dry and make sure you dispose of any paper towels or rags you use by sealing them in a heavy-duty plastic bag and placing the bag in a garbage can located outside the home.
  • Clean all metal surfaces: use vinegar to clean all surfaces inside the HVAC main unit as much as possible. Then allow at least one hour of drying time before turning the HVAC system back on.

    How To Clean Mold From Air Conditioner Coils 5 Easy Steps

    How to Remove Black Mold In AC Units?

    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.

    How To Prevent Mold In Air Conditioner

    Mold in your air conditioner how to identify

    Fortunately, there are a few steps you can take to prevent mold from developing in your air conditioner:

    • Reduce moisture. The easiest way to avoid moisture build-up in an AC unit is back when you purchase it. Look for an AC unit with humidity control. Many modern units vent water vapour with air. If you have a unit that is designed to collect water in a reservoir, empty it regularly.
    • Avoid organic debris. In addition to water and air, mold needs organic matter to breed. Clean or replace your air conditioners filter regularly, and vacuum the interior to clear out any dust and debris. Dont give mold any food to live on!
    • Keep unit running while on vacation. Mold tends to build up when the air conditioner is not running and the air is still. Keep your unit running, even when on vacation. To reduce energy consumption, you can set the target temperature higher so it runs less often, but dont shut it off altogether.

    Unfortunately, air conditioners represent a particular problem area for mold, since they push the air and mold spores through the house and into the air you breathe. The risk of black mold in particular makes it important to be vigilant about mold in air conditioners and nip problems in the bud.

    It may feel intimidating, but dont feel discouraged. Knowledge is power, and knowing to keep an eye out for mold in your air conditioner will help you keep your home healthy and happy.
