Signs of Black Mold in Air Vents

Your AC ducts may be infested with black mold if you are experiencing any problems in your home, including:

  • A strong, musty odor in the house, stronger in particular rooms.
  • The smell intensifications when you switch on the AC.
  • Your eyes, nose, and throat feel irritated when you enter the air-conditioned room.
  • You can spot the mold spreading in air ducts, vents, or drip pans of the AC.

What Causes Mold on AC Vents?

A warm location which has elevated water vapor content is usually more prone to mold buildup. Water vapor forms within the AC duct system when the outside environment has high water content, and the water droplets get collected inside the duct instead of evaporating.

Molds can cause serious health problems, such as sinus infections and asthma. Some of the other health risks linked with black mold are allergic reactions, invasive disease, irritation due to volatile organic compounds, and mycotoxicosis.

Is Duct Cleaning Worth It?

Currently, there is no research to show that routine duct cleaning reduces dust or increases the air quality in your home. However, studies show that dirty cooling coils, air handling units, and motors will reduce the efficiency of your HVAC unit.

Here are some mold prevention measures that you can employ to eliminate recurring mold problems:

  • Replace the filters of the HVAC system.
  • Insulate the air ducts to reduce the condensation rate within them.
