Mold Inspection & Mold Removal

At AirWiz we often first spot a mold infestation during a routine air duct cleaning appointment. As we inspect the system and access the ductwork to clean it, we can sometimes see it. We also look for it in places prone to mold growth: coils, plastic, stickers, labels, cables, wires, and insulation.

Signs of a Mold Infestation in the Air Ducts

Worried you have mold in the system? Check for these signs:

Allergies and unexplained sickness. Mold in your home can cause allergies and illnesses you can’t explain or that don’t go away. Some of the symptoms include:

  • Sneezing and coughing.
  • Itchy nose, throat, skin, and eyes, and rashes.
  • Runny or stuffy nose.
  • Chronic fatigue or low energy levels.
  • Dizziness or persistent headaches. These symptoms will be more pronounced in people already suffering from allergies, asthma, or compromised immune systems.

Strong, musty odor. If you smell a musty odor when your HVAC system kicks on, suspect mold. The closer you get to the vent where the mold is growing the stronger the odor will be. If you ignore the problem, it will soon spread throughout the duct system to all areas of your home. The sooner it’s remediated the easier it is to eradicate.

Visible mold around the vents. As mold spores get pushed through the HVAC system, they can begin growing around the air vents. If you see yellow, green, brown, or black growth, suspect mold.

Remediation Process

As we remediate mold from ductwork, we follow a four-step process.


We identify the areas that contain mold.


We wet-clean the areas to wash the mold from the surfaces.


We disinfect the surfaces with our powerful nontoxic botanical cleaner. EPA-approved Benefect® Disinfectant contains Thymol, a bactericidal, virucidal, fungicidal, and tuberculocidal product. It kills on contact.


Some of our clients like to also use a UV light air purifier to make sure all harmful substances are removed from the air on a contiuous basis.
