How Do You Know There is Mold in Your Air Ducts?

Most of the time molds are visible. When they are invisible, however, you’ll get their odor in the air or have people or pets in the house show certain symptoms.

The odor is often the first sign of mold in air ducts or air vents – you mostly smell it before you see it. So, if you begin to perceive a musty or moldy “wet” smell whenever you are not using your air conditioning or heating (if they share ducts), know that mold is growing in your HVAC system.

The visible mold will turn up around AC vents, in the ducts, and in the drip pans – look out for them! Because condenser coils pull moisture out of the air and into drip pans, they become the perfect environment for mold to grow, especially if clogged.

Finally, when people or pets in the house start exhibiting symptoms like headaches, nausea, irritated nose and throat, and itchy eyes whenever the AC is on, one possible cause is mold in air ducts.

Why Would Mold Grow in My Air Ducts?

Mold grows in ductwork when there is moisture and the temperature is warm. A warm, humid environment is the ideal place for mold to thrive in, and Houston, Texas is one such place where you may always need the service of mold remediation companies.

Mold could also grow in your air ducts when you have HVAC problems such as:

  • An oversized AC unit – larger units in small spaces cool off the air too quickly and go off before dehumidifying the air, leading to the excess moisture that mold needs to thrive in.
  • A leaking duct – ducts that have leaks that let in warm air creates the temperature differential that can invite mold.

Also, if you set your AC on a very low temperature always, you could just be creating the right environment for mold to settle in your HVAC duct.

How Can I remove Mold from Air Conditioner Duct and Ceiling?

Mold on ceilings is usually visible and can be removed easily. You can remove mold on your ceiling with vinegar or bleach.

Most Houston, TX residents who have had to remove mold from their ceilings themselves prefer to use vinegar over bleach because it is 100% natural and safe.

Removing mold from your ceiling with vinegar would involve the use of a ladder, spray bottle, white distilled vinegar, scrubbing brush, plain water, and clean cloths.

To go about mold removal from the ceiling with vinegar, do the following:

  • Pour the vinegar into the dry spray bottle (do not mix any water in it) and spray a good amount to the areas infested by mold. Allow it to sit for an hour.
  • Using a clean cloth soaked in plain water to wipe away the mold from the walls and ceilings. You can also use a scrubbing brush with firm bristles for hardened fungus and stains.
  • Use a dry, absorbent cloth to soak up moisture by dabbing or pressing against the cleaned areas. Keep the windows in the house open to dry the area quicker and allow the vinegar smell to go out.
  • Spray ceiling corners and other areas where mold is likely to grow once or twice a week using the same vinegar in the bottle to help prevent mold growth.

Removing mold from the air conditioner ducts in your Houston, TX house isn’t as easy as removing it from the ceiling. You would surely need the assistance of a professional mold remediation company near you to do the job.
