Mold in AC Units: Give Mold the Cold Shoulder!

It’s HOT in Florida and your AC is working overtime. Smelling a musty smell even after changing the air filters? Instead of candles or air fresheners, consider having your air ducts inspected for mold.

Mold can grow in any area of the HVAC (heating, ventilation, and air conditioning) system where moisture is present, including inside air ducts. Here are some common areas where mold can be present in air ducts:

Air ducts: Mold can grow on the inside surface of air ducts if moisture is present. This can occur if there are leaks or condensation in the ductwork, or if the humidity levels are high.

Air handler: The air handler is the part of the HVAC system that circulates air through the ducts. Mold can grow on the coils and other surfaces inside the air handler if moisture is present.

Drain pans: The drain pan is located beneath the air handler and collects condensation from the coils. If the drain pan is not properly maintained or if there is a clog, standing water can accumulate and provide a breeding ground for mold.

Grills and diffusers: These are the vents that distribute air throughout your home or building. Mold can grow on these surfaces if they are not cleaned regularly or if there is moisture present.

Once mold starts to grow in air ducts, it can spread throughout the entire HVAC system, potentially affecting the air quality of the entire building.

It’s important to note that mold growth in air ducts can be difficult to detect, as it is not always visible. In some cases, mold growth may only be detected through the presence of musty odors or allergy-like symptoms. If you suspect that your air ducts may have a mold problem, contact Bio Pro Mold Assessment to assess the extent of the problem and determine the best course of action.

If you suspect mold in your air ducts, here are some steps to remediate:

Inspection: The first step in remediation is to conduct a thorough inspection of the HVAC system to determine the extent of the mold growth. This may involve visual inspection, air quality testing, and/or sampling of surfaces. This is a service Bio Pro provides.

Identify the source of moisture: Once the extent of the mold growth has been determined, it’s important to identify and address the source of moisture that is allowing the mold to grow. This may involve fixing leaks or improving ventilation to reduce humidity levels.

Contain the affected area: To prevent further spread of mold spores, it’s important to contain the affected area. This can be done by covering the vents with plastic sheeting and sealing them with tape.

Remove mold from ductwork: To remove the mold from the ductwork, specialized cleaning techniques and equipment are often required. This may involve using HEPA vacuums, scrubbing the ductwork with brushes or specialized tools, and applying antimicrobial agents to disinfect the surfaces.

Replace contaminated components: In some cases, it may be necessary to replace contaminated components of the HVAC system, such as filters or insulation. This can help ensure that all sources of mold growth are eliminated.

Clearance Test: After remediation, a final inspection should be conducted to ensure that all mold has been removed and that the air quality of the building has been restored to safe levels.
It’s important to note that mold remediation in air ducts can be complex and should be performed by trained professionals with experience in this area. Attempting to remove mold from air ducts without proper training and equipment can be dangerous and may not be effective.

In summary, mold growth in air ducts can be a serious problem that affects the air quality of a building. Taking preventative measures can help avoid mold growth in air ducts and ensure that the air quality of the building remains healthy and safe for occupants.
