What Causes Black Mold In An Air Conditioner
There are a few different things that can cause black mold in an air conditioner. The most common cause is moisture. Mold thrives in an environment with moisture, darkness, still air, and warmth.

One of the most common reasons the black mold will grow in your air conditioner is a clog. When a clog happens in the condensate drain, it can cause water to back up in the unit. Which provides the perfect environment for black mold in an AC unit.

Another way to tell if there is black mold in your air conditioner is by noticing a musty smell. If you notice a musty smell coming from your AC unit, that’s another good indication that there is black mold growing inside of it.

How to Clean Mold From an Air Conditioner
Now that you know how to tell if there is black mold in your air conditioner, let’s talk about how to clean mold from an air conditioner. If you have a small amount of mold, you can try to clean it yourself with bleach and water.
Start by unplugging your AC unit and then disassembling it so you can access the coils and drip pan. Next, make a bleach solution with a few gallons of water and 1/2 a cup of bleach. Saturate a sponge or cloth in the solution and then wipe down all of the affected areas. Any remaining mold spores will be eradicated by the bleach.
Make sure to use cleaning gloves and goggles so that you don’t have bleach touching your skin!
Once you’re done cleaning, reassemble your air conditioner unit and plug it back in. You should notice a difference in the musty smell and the overall air quality in your home.

How to Clean Mold From a Central AC Unit
If you have a central AC unit, the process of how to clean mold will be different. This is because central AC units are using ductwork which can make this process much more complicated and involved.
The first thing you need to do is identify where the mold is. If it’s just in the AC unit, then you can follow the steps above. But if the mold has spread to the ductwork, you’ll need to take a different approach.
The EPA suggests that you turn your unit off as soon as you think there is mold growing. Otherwise, the mold can spread through the ductwork. In order to clean mold from the central AC unit, you’ll need to vacuum and clean the air ducts thoroughly.
This typically will need to be done by an expert as it requires quite a bit of work and can be difficult.
