How Do I Know If I Have Mold In My Air Conditioner

Check air conditioner for black, green mold spots

How do I know if I have mold in my air conditioner? A few days ago, someone asked me this question. This is a very excellent question to ask, by the way.

Do you know why molds grow in your air cooling system? Molds can grow anywhere in your home. From walls to ceilings to machines, anywhere it can grow if it gets proper food. Yes, you heard me right, proper food.

Do you know what molds eat? Dust and moistures. Anywhere in there is trapped dust or moisture build-up, molds will grow there.

Today we will learn how to know if you have mold in your aircon system. I hope this article will help you to know your answer. So without any delays, lets get started.

How To Check For Mold In Air Ducts

Mold spores thrive in an environment that is warm and moist, such as an air duct. Thus, mold may develop in your air ducts if you have an excessively wet atmosphere with no ventilation or any space that traps moisture in your walls and causes condensation.

Mold testing can help determine if you have mold in air ducts. Mold is often confused with dirt or dust, and you could waste your time and money in the removal process. To confirm that the substance in your HVAC vents is mold, contact a certified mold inspector. They offer laboratory analysis of samples taken from your air ducts.

Besides a mold test, you can also use your nose as the fungus also gives off a distinct musty odor. When your heating or air conditioning is on, you may notice the smell. It will usually be strongest near the mold development vent. As a result, the scent may not be noticeable throughout the entire house but can still be detected in one particular room. On the other hand, the stench might very well continue to linger in adjacent areas and elsewhere throughout the structure.

Mold in air ducts that goes unaddressed for an extended period will absolutely spread throughout the rest of the HVAC systems. Eventually, you may detect the musty odor in every nook and cranny of your house.

How To Clean Mold Out Of Ductwork

Mold gets into your homes ductwork when there is moisture inside the ductwork. As your air conditioner circulates cool air through the air ducts on hot days, the humidity in the air can condense in the ductwork. The moisture in the air beads up on the walls of the ducts. The presence of this moisture allows mold spores to grow and colonize inside the ductwork.

Mold spores get into the ductwork by blowing in elsewhere in your home or from the outdoors. The warm moist environment in the ductwork can be an ideal place for mold to grow. When it is growing in your air ducts, the spores will be circulated through the mechanical equipment, blown through your system and into the air throughout your entire home. This may be one of the biggest reasons why you need to clean your duct work.

Mold On Air Duct Vents

One of the obvious signs of mold living inside your homes air duct system is seeing the fungus patches on the vent grates.

Take a look at the air duct vents throughout the house. Open the grates and remove the air filter. Mold spores appear as splotches of black, green, or white patches.

For a thorough duct system check and mold removal, contact a specialist for an evaluation.

Detergent And Baking Soda

How To Remove Mold From Air Conditioning Vents

Similar to our laundry detergent method, this is a little more heavy-duty because of the added baking soda. All you need is one tablespoon of laundry or dishwasher detergent, half a tablespoon of baking soda and one cup of water. Increase these ratios as needed.

  • Turn off the AC or heating.
  • Mix the solution in a large basin. Increase the ratios depending on how large your basin and air vents are.
  • Unscrew the air vents and submerge it into the cleaning solution.
  • Let it sit for 15 minutes.
  • Use a HEPA vacuum to clean out the inside of your air vents.
  • Use the same baking soda and detergent solution to clean out the inside of the air vents. You may need a long-handled mop to get deep into the vents.
  • After 15 minutes, use a scrubbing brush to scrub off the mold, mildew or dirt on your air vents.
  • Dry thoroughly.
  • Use a dry cloth to dry the inside of your air vents, too.
  • Once everything is dry, reattach the air vent.

    How to Clean a Dirty Moldy Window Air Conditioner

    If you find a musty smell coming out of your air cooling system, it means there are molds built around somewhere inside of your aircon system.

    The favorite place for a mold to grow inside of your aircon system is in the evaporator coil. The evaporator coil is located in black and in a greasy, or you can say full of moisture location. It is very easy for molds to grow there.

    Apart from there is an AC drain pan which is another favorite for molds to grow. These drain evaporator coils, drain pans, etc., are the primary source of bacterial growth. So always clean them.

  • Inspect The Plenum
  • Examine the Return Air Vents
  • Inspection of AC coils
  • Reply: A Combination Of Steps Can Help Assess Mold Contamination In An Hvac System

    What makes sense to me is to take the following mold inspection and testing steps if you have not already done so:

    • A visual inspection of the air handler, return and supply plenums, visible areas of ductwork for evidence of leaks, dirt and debris, visible mold, insect debris, etc. I worry that it’s too easy to “decide” that we have a mold problem in one specific place without an adequately thorough inspection and taking of the case history. The result is the unnecessary expense of having to keep bringing back cleaning or testing people to the property. If we can do so, it’s less costly to do it right the first time.
    • A tape sample test of a clean newly installed air filter after it has been in place for 2 weeks to a month in your HVAC system – a procedure is at TEST KIT for DUST, MOLD, PARTICLES: INSTRUCTIONS – you can use any qualified mold test lab This presumes you have a centralized air filter in your duct system or air handler.
    • A tape sample of debris accumulated on the central air return register grille and on a dusty supply register grille sample too.
    • A tape sample of suspected mold growth on the HVAC duct interior If visible mold is observed inside the ductwork it may be useful to collect a tape sample of that as well, but beware that a modest amount of Cladosporium sp. is very common where condensate blows around in the duct system, and may be visible, but may by no means be the significant problem in the building.

    Mold is a type of fungus. Like all living organisms, fungi require three things to grow: oxygen, water and organic matter. Since air conditioners circulate air and the cooling coils tend to create condensation, the first two criteria for mold growth are bound to be present in an air conditioner.

    Air conditioners and ductwork also provide the dark spaces where mold can thrive. Add some organic materialwhich can simply be dust and other debrisand you have all the conditions for mold to grow.

    What To Do If You Have Mold In Your Air Conditioner

    Finding mold in your air conditioner is a problem that you should deal with immediately. If the mold is heavily infesting a small air conditioner, it’s recommended to replace the unit with a new air conditioner because even with significant cleaning there is a high chance that the mold will continue to thrive in unseen areas of the appliance. However, if the mold is relatively light, then you might be able to get rid of it before it spreads throughout the AC unit.

    Wear safety glasses, a face mask, and gloves, then move the unit to a space where it can be cleaned without contaminating the rest of the home, such as the driveway. Open the air conditioner and remove the filter. You can either replace the old filter if it is disposable or wash the filter in a mix of 1 part liquid bleach to 10 parts water, allowing it to soak for at least 10 minutes to kill any mold.

    Rinse the filter and allow it to air dry. While the filter dries, deep-clean all affected surfaces of the air conditioner with the solution of bleach and water. Rinse off the AC unit, being careful not to soak any electrical components, and allow it to dry before reinstalling the filter.

    How Does Mold Get Into Hvac Systems

    Any environment that is affected by moisture can be prone to mold growth. The summertime is humid. Plus, vapor develops in the ductwork as the cold air runs through warm ducts. Whenever the heating, ventilation and air conditioning system isnt running, water droplets can collect in the air handler or ducts. Instead of evaporating, the water inside the system accumulates and gets warmer. This becomes the perfect place for spores to grow. Then, built-up dust, skin, and pollen particles act as fuel for mold infestation inside the air conditioning system.

    Checking For Mold Inside Furnace

    Mold thrives in dark and damp settings. These conditions present a perfect environment to multiply. Testing for mold on your furnace is easy. You only need to pay attention to the condensation around the furnace components to notice any unusual build-up. The furnace often heats and humidifies the air inside, and where there is humidity, there can be mold. The pollution of indoor air often begins from mold accumulation around the furnace.

    If you notice mold around accumulating on the furnace, its a good idea to contact Beyer Air Conditioning and Heating. The specialist will be able to assess the extent of damage and prepare for duct and furnace cleaning. You might need to act fast in such cases to minimize the risk of air-borne complications.
