    Signs Of Mold In & Around Your Ac Venting

    Mould Removal Air Conditioning Cleaning in Brisbane

    There are various signs of mold in and around the AC venting, including odor, visible mold, mildew, and allergy reactions.

    Musty Odors

    Mold smell coming from AC vents is usually the first sign one experiences. The trapped moisture becomes stale in a poorly ventilated home, and soon there will be a persistent foul odor, especially if the AC is running.

    Usually, the musty smell becomes quite strong near the AC unit. If the mold stays there for long, the whole house will soon be in havoc. I recommend you call for professional help the first day you smell this musty odor to prevent mold from spreading further.

    Visible Mold & Mildew

    Sometimes, mold and mildew in vents and around the air ducts become so big that one can easily spot them. This formation happens after the AC condenser coils extract moisture from the warm air, settling in and around the AC vents.

    Allergy-like Symptoms

    Here is another obvious sign of mold growing in and around the AC vents. The biggest side effect of being exposed to mold is feeling sickly. Whoever breathes in tiny mold spores will most likely suffer from allergy-like symptoms.

    Homeowners might experience headaches, nasal congestion, nausea, itchy eyes, irritated throat, and skin rashes.

    With such illnesses, I highly recommend stopping using the AC unit until the mold is cleaned out. Prolonged exposure to mold spores can make the situation even worse.

    Causes Of Mold In Your Heating And Air Conditioning System

    The two major causes of mold in your air conditioning system are condensation and organic material. Condensation occurs when parts of your air conditioning system get cold, especially when the surrounding air in the room is warm and humid. For example, if your basement tends to be humid and the air ducts get cold while the air is blowing, the water vapor in the room can begin to condense on the air duct, creating a small amount of water. If the humidity is low enough, the water will quickly evaporate once the a/c turns off. If the humidity is too high, then the water will persist and thats when you begin to have a mold problem.

    Air conditioning systems tend to collect dust, both in the unit itself and within the air ducts. Dust contains all kinds of organic material, such as pollen and dead skin cells, which is essentially food for mold. Combined with a damp environment, this creates a great place for mold to grow.

    Diy Remediation For Mold In Hvac Systems

    How To Clean Mold from Your Window Air Conditioner Safely ...

    Personal protection equipment, or PPE, is the essential first step for the do-it-yourself individual. Gloves, safety goggles, and a N-95 rated mask are required to ensure your personal safety while remediating mold.

    Once again, make sure the system is shut down. Turn off the appropriate circuit breaker to ensure that the furnace or air conditioning unit will not come on. Remove any furnace filters, bag them up, seal the bags closed, and dispose of them. Next, choose a cleaning solution containing baking soda, borax, or household detergent and mix it appropriately with water. . Fill a spray bottle with the solution.

    Using a HEPA vacuum, remove as much visible mold as possible. Then generously apply your cleaning solution on the moldy areas using the spray bottle and allow the solution to dwell for several minutes. Using towels that can be thrown away, wipe the areas where you saw the mold. Then repeat vacuuming with the HEPA vac. Sometimes you may need to repeat this entire process, especially if there was a lot of mold present. Dont forget to bag the dirty towels before removing them to a trash receptacle.

    Lastly, apply a mold inhibitor to control mold growth inside your HVAC system. Make sure that you use only EPA registered products that are intended for use on heating and cooling systems. Keep in mind that mold can grow in as little as 48 hours, so after a couple of days you should re-inspect your system.

    Setting Ac Temperature At Too Low

    If the air conditioning at your home is set at a very low temperature in order to conserve energy, condensation can form, particularly around ventilation ducts that are close to exterior walls. This moisture should dry out if left alone. But when this does not happen for an extended period of time, mold growth may ensue. To avoid this outcome:

    • Turn the AC up to a more comfortable temperature
    • Increase airflow with open windows or fans
    • Position your outdoor condenser unit away from exterior walls, fences, and other objects that could trap moisture

    Though rare, the moisture problem can apply not only to cases where there are no leaks in your ducts but also to conditions where your HVAC ducts have leaks and allow warm air into them. In this case, you will need extensive duct cleaning with mold remediation and should seal up any existing leaks on the airways themselves.

    Mold In Your Air Conditioner Is Very Prevalent In Homes But Diagnosing It And Determining If Its Harmful Can Only Be Done By Experts

    Its common to find mold in your air conditioner or furnace. Your furnace and evaporator coil have all the components necessary for things like mold to develop. Primarily because theres consistent moisture. Even if you have your furnace and air conditioner maintained every year, the process of heating and cooling your home necessarily creates condensation that doesnt completely go away.

    Couple that with the areas of moisture being hard to reach, and you have an environment where mold can and does develop.

    What Causes Mold To Form In Air Conditioners

    Mold in air conditioning units is mostly the result of not cleaning the system or having regular maintenance done on it. Over time, your ac unit will collect a large amount of dust and dirt from inside and outside your home, which mold can feed on.

    Therefore, cleaning and having yearly HVAC maintenance done pays off in the long run because mold deteriorates and destroys the surfaces it grows on. If it finds its way onto vital components within the system such as styrofoam and coils, it will not function correctly and eventually cease to work while causing health problems for the house occupants.

    Leakages within the ac unit are another cause, which is usually the result of an incorrectly installed system or due to a lack of maintenance. The water which accumulates attracts more dust than usual, and both the water and dust fuel mold growth within the air conditioner.

    The final cause of mold in the ac unit is from not running it regularly. If it stands unused for extended periods , mold spores will get a chance to develop into mold. Its recommended to run your ac unit each day for a few minutes to clear out the vents. That way, when summer comes around, you wont have any nasty surprises.
