What Causes Mold Development in Your AC?

In a previous post, we discussed duct cleaning and some signs that it’s time for you to have this service done. One reason to invest in duct cleaning is due to the development of mold in your system. But how does it get there to begin with? Keep reading to discover some of the most common reasons for mold growth in your air conditioning unit.

Aging System

As your air conditioner ages, it becomes more prone to wear and tear and doesn’t perform as well as it once did. An older system is unable to deal with extreme temperatures and high humidity as well as a newer, more efficient system can. Therefore, humidity levels stay high and promote mold growth within your AC.

AC Coil

Do you keep up with your routine maintenance appointments? These should be made yearly, at least. When you neglect maintenance tasks, then your air conditioner’s coils can begin to collect dust and debris. When cool water drips and is added to this debris, then mold starts to grow and spread.

Drain Line

Is your condensation drain line cleaned out yearly? If not, it can become clogged and cause water to back up into the HVAC unit. Since most HVAC units have insulation at their base, this water creates moisture that can take months to dry out. Mold only needs a week or two to develop.

Humidifiers

Humidifiers are great appliances for homes that suffer from too dry of air. Your relative indoor humidity should be between 30-50%. The problem arises when people run their humidifiers despite their levels being within the normal range. If you forget to turn off your humidifier during a time that it’s not needed, it can create added moisture within your home and lead to mold.
