What Causes Mold to Grow in Your Air Conditioner?
Before we get into the signs that there may be mold in your air conditioner, it’s important to understand what causes mold to grow in your air conditioner. Here are a few factors that contribute to mold growth in air conditioners:
1. Poor ventilation
One of the most common reasons for mold growth in an air conditioner is poor ventilation. When your AC unit doesn’t have enough ventilation, condensation can build up, which provides the perfect environment for mold spores to grow and multiply. To prevent this from happening, make sure there is at least a 1-inch gap between your air conditioner and the wall or other surface it’s mounted on
2. Leaks
Another common cause of mold growth in air conditioners is leaks. Leaks can occur in the ductwork, evaporator coils, or condensate drain line. These leaks provide moisture that mold spores can use to grow and multiply. To prevent leaks, have your ductwork professionally inspected and sealed every few years and check your evaporator coils and condensate drain line regularly for signs of leaks
3. Dirty filters
Dirty filters are one of the most common issues that lead to mold growth in air conditioners. When your AC filter is clogged with dirt and debris, it can’t do its job properly, which allows dust and other airborne particles to build up on the evaporator coils. This buildup provides a food source for mold spores, allowing them to grow and multiply quickly. To prevent this from happening, change your AC filter every 1-3 months or as needed.
How Can I Tell if Mold is Growing in My Air Conditioner?
It’s important to know the signs of mold growth in your air conditioner so you can take steps to prevent it from growing. Here are a few common signs that there may be mold in your air conditioner:
- Discolored ductwork: If you can see mold growing on the outside of your ductwork, there is a good chance it has also made its way inside the ducts.
- Musty smells: A musty smell coming from your vents is another sign that mold might be present.
- Visible mold growth: Of course, one of the most obvious signs of mold is visible growth on or around your AC unit.
- Health problems: If you or someone in your family starts experiencing inexplicable health problems—such as coughing, sneezing, watery eyes, headaches, or difficulty breathing—it could be due to mold spores in the air.
If you notice any of these signs, it’s important to take action immediately. The longer you wait, the more time mold has to grow and spread.
What to Do if You Find Mold in Your Air Conditioner?
If you find mold in your air conditioner, the first thing you should do is turn off the unit. Then, remove any visible mold using a solution of equal parts water and bleach. Be sure to wear gloves and a mask while you’re doing this. Once the mold is gone, clean the area with a solution of vinegar and water.
Next, you’ll need to address the underlying problem that caused the mold to grow in the first place. This is usually due to a build-up of dirt and dust on the coils. Clean the coils with a solution of soap and water, then rinse them thoroughly. If the coils are very dirty, you may need to replace them entirely.
Once you’ve taken care of the mold and cleaned the coils, turn on your air conditioner and check the air filter. If it’s dirty, replace it with a new one. Lastly, be sure to have your air conditioner serviced regularly by a professional to prevent future mold growth.
