Black mold can cause severe respiratory symptoms, particularly in people who are allergic to mold. After you clean your air conditioner vents, inspect walls and insulation to find the source of the black mold infestation.

  • Wear long sleeves and pants and put on a high-efficiency dust mask to protect yourself from black mold spores. Make sure all household members with mold allergies or respiratory problems are out of the house before you begin to clean the air conditioner vents.

  • Remove the vent cover of a window air conditioner by unscrewing the screws with a screwdriver or pressing in on pressure clips. Place the vent cover in a basin or tub, sprinkle with laundry detergent and add enough water to cover the vent cover. After 15 minutes, rinse and allow the filter and vent cover to air-dry.

  • Remove dust from the inside of the air conditioner, as the dust in the moist environment allows mold to thrive.

    • Keep your HVAC ducts clean

    Mold The Stubborn Intruder: What Is The Cause

    In most cases, homeowners can most efficiently remove the mold form visible areas. However, molds spread through spores, and the presence of a small colony can lead to a re-infestation in no-time. Mold problems in HVAC systems and subsequent air ducts occur due to humidity and water accumulation in the system. Unless you find out precisely what is responsible for the growth in the first place, you might find yourself fighting a losing battle.

    The DIY solutions are only suitable for minor mold problems. These are more effective for isolated cases that do not involve the entire ductwork. For example, if your master bathroom or your storage room smells musty, you can try to scrub the particular duct or vent that aerates these rooms. It is very common for some places to gather mold in the ductwork more than the others. Bathrooms are often more prone to mold infestations since there are higher humidity levels, and water almost never dries up completely. There is a high chance of recurring mold growth in the bathroom, and research shows that over 70% of toilets and showers in the urban areas have sneaky mold problems.

    Do Sealants Prevent The Release Of Dust And Dirt Particles Into The Air

    Manufacturers of products marketed to coat and encapsulate duct surfaces claim that these sealants prevent dust and dirt particles inside air ducts from being released into the air. As with biocides, a sealant is often applied by spraying it into the operating duct system. Laboratory tests indicate that materials introduced in this manner tend not to completely coat the duct surface. Application of sealants may also affect the acoustical and fire retarding characteristics of fiber glass lined or constructed ducts and may invalidate the manufacturer’s warranty.

    Questions about the safety, effectiveness and overall desirability of sealants remain. For example, little is known about the potential toxicity of these products under typical use conditions or in the event they catch fire.

    In addition, sealants have yet to be evaluated for their resistance to deterioration over time which could add particles to the duct air.

Each company will have its own recommendation or process, and theres no universal solution given the range of vents found in homes today.

    When your solution is ready, you simply need to scrub the area until the mold is removed. It may take more than one application, but when you are done, dispose of rags, brushes, or scrapers in an airtight construction bag. When satisfied, the next step should be to use a mold inhibitor in the area to ensure it doesnt return.

    Mold can grow under the fridge by the motor area, beneath the kitchen and bathroom sinks, and on the bathroom ceiling and walls. This is especially true when there is no window in the bathroom and the only ventilation is a vent fan. Its important to make sure that the bathroom vent fans are working and exhaust the unwanted moisture from a steaming shower.

    Unpleasant Odor From Ducts

    Another telltale sign of the presence of debris in the system and that you should conduct serious ventilation system cleaning is odor. If you experience an unpleasant smell in your home and can’t find the source, it could be emanating from the air duct system. You should get up close to all the air registers for a good sniff to verify these suspicions. You can also have a technician inspect the air ducts for anything that could be emitting the bad smell.

    Suggestions For Choosing A Duct Cleaning Service Provider

    To find companies that provide duct cleaning services, check your Yellow Pages under “duct cleaning” or contact the National Air Duct Cleaners Association at the address and phone number in the information section located at the end of this guidance. Do not assume that all duct cleaning service providers are equally knowledgeable and responsible. Talk to at least three different service providers and get written estimates before deciding whether to have your ducts cleaned. When the service providers come to your home, ask them to show you the contamination that would justify having your ducts cleaned.


    • they are experienced in duct cleaning and have worked on systems like yours
    • they will use procedures to protect you, your pets and your home from contamination and
    • they comply with NADCA‘s air duct cleaning standards and, if your ducts are constructed of fiber glass duct board or insulated internally with fiber glass duct liner, with the North American Insulation Manufacturers Association’s recommendations.
