Cheap and Easy Way to Kill Allergy Causing Mold from Air Conditioning System

Cleaning up mold can be difficult, messy, and the process of cleaning mold out of an air conditioner is dependent on the type of unit. Car AC units, window units, and central AC units differ greatly regarding the resources needed to eradicate them of mold. Regardless of what you are cleaning, the area where you perform the clean-up should be well-ventilated, and you should wear non-porous gloves and a face mask with goggles, especially if you are sensitive to mold. Mold can be wiped up with a household cleaner and a cloth or sponge. Bleach is not needed to remove mold. If mold has grown on a porous surface such as wood, plaster, carpet or upholstery, you will probably not be able to get rid of all the mold. The moldy item or section will need to removed, thrown away and replaced.

Window unit: By the time you see small mold spots forming on the air direction vanes or grate of your window air conditioner, it is probably too late. The mold you see is just the tip of the iceberg. You can disassemble the unit and try to clean mold from the internal air ducts, coils, evaporators and other parts, but there is always a chance you will miss some and the mold will simply grow back. A moldy window unit likely needs to be replaced.

How To Remove Black Mold From Air Ducts And Vents

Removing mold that has begun growing inside air vents can be a challenge. Some experts recommend using ozone, but the CDC and other agencies have warned that this method of removing mold can be damaging to the respiratory system. Mold can be killed with a mixture of one cup of bleach per gallon of water, but chances are good that you wont be able to reach the mold deep inside the duct work of the home. Instead, you can follow these steps to kill mold in air vents:

Step 1: Have the substance you suspect to be black mold tested to be sure that it is actually this type of fungus. You can avoid a potentially time consuming and costly cleanup with this simple test.

Step 2: Identify the main cause of the mold in your home. Wet wall interiors and damp baseboards can contribute to mold. Identify and treating the main cause of mould will ensure the problem doesnt reoccur.

Step 3: Check the insulation surrounding the ductwork. If the mold in your air vents has extended into the surrounding insulation, you will need to replace this material.

Step 4: Clean the interior of the air vents using a professional cleaner who has been recognized by the NADCA. Since improper removal of mold can be a waste of time, and money, you will want to choose someone who has experience and specialized knowledge in removing fungus.

How To Remove Mold From Hvac System

When it comes to cleaning mold, there are a number of chemicals and natural cleaners that can be used, although some will be more effective than others, depending on the species and how far it has penetrated.

Removing it from air ducts deep within your home can be tricky because they can be hard to reach, so you may have to remove them from their place in order to clean them properly. But you can follow these steps in removing mold from the air vents first to prevent the majority of the mold from spreading to other areas.

  • Wear personal protection. Protecting your health and safety is the first priority in any cleaning process. Make sure that you are wearing gloves, eyewear, and a breathing mask to avoid all contact with the mold.
  • Turn off the HVAC system. As long as the air is blowing, mold spores are floating throughout the ductwork, making it extremely dangerous to your health.
  • Identify the cause. Finding the cause of the mold is essential so you wont have to worry about it returning in the future when you are done cleaning. For example, if moisture levels within your home are too high, they need to be turned down. Or if there is too much water running in the air conditioning unit, there is significant condensation within the ductwork that is allowing the spores to develop.
