Because it’ll be a bummer if you’re going home, and the very first thing you’ll encounter is your air conditioner having such problems. Especially if you’ve gone for a long day and all you ever wanted was just a good rest, though you cannot achieve it because of the molds.

The molds forming in your airconditioner indicate that your AC unit is dirty, and you need to clean that instantly if you don’t want to trigger your allergies or let dirt contaminate the air in your room. So, read on to learn how to keep molds from growing in your air conditioner.


Preventing Molds In Air Conditioner

Mold grows mostly on any surface as long as the area is covered in darkness and humid, and your air conditioner is no exception. Since it’s dark inside the air conditioner and during its cooling process, and high humidity is present, molds will very much flourish.

If you don’t do something about it, the moldy AC unit will blow tiny mold spores all over your room which is the last thing you want to happen because it is a threat to your health, especially to your lungs when you breathe dirty air. So, make sure to take down notes and learn how to prevent molds in air conditioner:


Method #1. Checking and maintaining the drain pans of the unit

Checking and maintaining your air conditioner’s drain pans regularly is one of the most efficient and common ways to prevent molds from coming into your air conditioning unit.

If you don’t clean pans at least once every two weeks or a month, water could not go through the trap with a deep seal. And if that happens, water, germs, and microbes accumulated there will result in molds growing, which will smell all over the area.

Now to avoid this, check on your drain pans from time to time and wipe them out once you’ve seen that germs and water have accumulated. Please do this at least every two to three weeks to ensure that the pans stay clean to avoid mold growth in there.


Method #2. Replacing your air filters

Mold grows in air conditioners for a variety of reasons, including wet and filthy air filters. Why? Because wet and dirt filters are ineffective in trapping bacteria and some spores contaminating your air filters. If you ever leave them just like that, these particles will start to accumulate inside of your appliance slowly and will allow molds to grow inside of it.

Doing this is simple and might cost you just a little bit of money one time in a month to replace the air filter that suits the model of your appliance, but prices may vary, depending on the model, type, and brand, so make sure you have enough cash on hand.


Method #3. Applying mold inhibitor onto the area

Mold inhibitors are the most effective chemicals to prevent mildew and mold growth in your appliances’ interior. Here is an article about that: “Fact Sheet: Mold inhibitors, mycotoxin binders, and antioxidants.”

Regardless, instructions are included on applying it according to the manufacturer’s included steps when buying one. Though not every brand comes with instructions with it most of the time, to apply it, it is all over the pieces of the cooling and heating units.


Method #4. Using a disinfectant

This one is one of the most needed steps to use before applying the inhibitor for molds towards your air conditioner. Disinfectants come in many varieties to ensure that the one you are picking is specifically used only for disinfecting air conditioning units.

To apply this, treat the areas with the disinfectant onto the surface where you would use your mold inhibitor later on. In that way, it’ll prevent and reduce molds or spores from ever coming back again into your appliance. And that is how to prevent mold in your AC system.



And that is how to prevent molds in air conditioner. With these methods, I hope you would put them to use and see results in a matter of time to avoid having problems. Ensure that you wear gloves, safety goggles, and a mask when you plan to clean your AC unit.

Again, the steps you can apply are applying mold inhibitors, disinfectants, replacing, and checking your filters.
