Mold thrives in moist areas, which is why the air conditioner is a prime location for mold growth. Moldy AC units can have a severe negative impact on the indoor air quality, as their job is to blow around cold air. Though you can take the time to clean out mold when you notice it, you are much better off learning about the causes of mold. This way, you can prevent the mildew from appearing in the first place.

Clogged Drain Line

The drain line of your HVAC system should be cleaned out at least once a year. If it isn’t, it can become clogged, which will cause water to back up into the unit. The majority of HVAC units are insulated around the base. Because of this, the water backup can take months to dry out entirely. Mold, however, only takes a week or two to grow.

Dusty AC Coil

Your AC unit should be maintained every year. When you don’t keep up with regular maintenance, your coils start to collect more dirt, dust, and debris. While the air conditioner is on, the cool water drips and accumulates in the debris. This leads to even more mold growth. To prevent the spread of mold, perform regular AC maintenance and clean the coils when they get dirty.

Too Humid

When humidity levels in the home are too high, mold grows much more quickly. The humidity indoors should be between 30 and 50 percent. If it is higher than that, mold indoor air quality in Norcross, GAbecomes worse. So, if your home is within the normal range of humidity, shut off your humidifier until you need it again.

Old AC System

Aging air conditioning systems are more susceptible to wear and tear. Your system just won’t perform as well as it used to. The older a system is, the less capable it is at handling extreme temperatures and high humidity levels. In this case, humidity levels remain high and mold grows inside the AC. When you notice your AC system is not working as well as it once did, it’s time to replace it.
