Owning an AC unit also means ensuring its optimum health. This includes no leaks, no weird noise, and most important of all, no weird smells. Even though it is common for an AC unit to have a certain smell to it, there are other indicating smells that suggest something wrong with your system.
One is a burning smell that indicates that the internal wires are burning, which could lead to a fire hazard. Another is a moldy smell that suggests mold is growing inside your system.
While some may consider this unimportant, if you notice the smell, immediately call for an emergency AC repair in St. Paul as it is harmful to one’s health.
What Causes a Mold to Grow in an AC System?
Like we see in nature, the key factors to mold growth are humidity and moisture. Considering how humid summer can become, one of the basic functions of an AC is to maintain the humidity balance within your home. However, this can disrupt the moisture balance within your system. Another way is caused by the water vapor forming inside the system’s warm ductwork when the cold air runs through it.
Once the unit stops working, this vapor becomes water droplets, which begin to collect within the air handler. However, instead of evaporating due to the warm ducts, the droplets build up and become warmer, creating the perfect area for mold spores to form and grow. Without a proper AC repair in St. Paul, MN, the accumulation of contaminants, dirt, and dust act as fodder that allows the mold to continue growing.
Things To Keep in Mind
Apart from the smell, it is difficult to know whether there is mold growing in your system, except during a maintenance service or when you schedule an AC repair in St. Paul, MN. However, for those who prefer to be alert, there a few indicators to look out for:
- The moldy smell is always near the air vents, and it increases whenever the system is switched on.
- Patches of black fungi begin to grow and form around the drip pans, evaporator coils as well as air vents.
- Health issues begin to arise within your families like runny nose, scratchy throat, or irritated sinus passage, especially when the system is running.
How To Prevent a Mold From Growing on an AC System

- Clean the drain pipes regularly to prevent them from getting clogged up.
