Mold in air ducts most commonly occurs when there is moisture inside the ductwork. The air coming out of the air conditioning vents is about 20 degrees colder than the inside air so if the air inside is too humid condensation will form on the metal ducts at. Black mold has a distinctive unpleasant musty smell.

It s not unusual for mold to accumulate around the vent on the wall or ceiling. Condenser coils pull moisture out of the air and into drip pans and if these become clogged they create the perfect environment for mold to grow. Common causes of black mold in air vents. Cold air cannot hold as much moisture as warm air so when warm humid air comes in contact with something cold it reaches dew point and makes condensation or water.

As cool air flows through the vents on hot days the moisture in the air can condense inside the air vent. This occurs when the grill is not tightened or the duct is not sealed allowing cold air to escape on the surrounding drywall. The black dust may be patchy and difficult to wipe off.

If there is black mold growing in your air vents you may notice a musty aroma when you run. When mold grows within the central heating cooling and ventilation system there are high chances that every room connected to the vents receives generous amounts of mold spores.

Condensation forms in the coils and ducts as cool air circulates through the system creating a habitat for moisture loving mold.
