How To Clean Mold Out Of Ac Unit

What Causes Mold To Form In Air Conditioners

Cleaning mold out of a window AC unit.

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.

Is Mold A Problem In Your Residence

If mold seems to plague your house, there’s a problem somewhere.

Your Central AC System – If you’ve got a central air conditioning unit, mold can grow in your ducts. This is particularly true if your ducts are the wrong size and/or if your AC or heat pump is the wrong size. These issues may not enable the dehumidification process, which goes to be complete enough. Water contracts on cold, mold spores and dusty sheet metal have all they have to grow.

We highly suggest having the machine looked at by an HVAC professional. Obtaining two remarks about what the issue is and the way to solve it’s a fantastic idea.

Your Home or Building You should definitely try to remove mold in your home. If that’s not possible this time w, or until it is done, an air purifier built to eradicate mold spores from the air is a great short-term option. Once the mold has been eliminated, the air purifier will keep your air cleaner and more breathable.

    How Does A Window Air Conditioner Work

    An air conditioning system is too complex to describe in detail in this article. Still, in brief, it transfers heat from a set of coils inside your window. Then, a compressor moves this to a set of coils outside the window.

    In a window AC, the hot and cold parts of the air conditioning system are in the same unit but separated by a panel. This is important to understand because there are two fans usually powered by the same motor.

    On the outside, it pulls air from the atmosphere to cool the hot coils. On the inside, it pulls air from your room to cool the air, thereby heating the coils.

    Wipe Down The Grill And Exterior

    While your filter is drying, wash the grill with warm water and mild detergent. Or if you don’t want to wash it, you can instead use a damp reusable cloth to wipe it down — just make sure to clean thoroughly in between the gaps where air comes out. Let it dry completely before reattaching it.

    Once you’ve cleaned the grill, wipe down the top and sides of the air conditioner. Take care to get inside of small spaces where it’s easy for dirt and dust to collect. Wait until the grill and exterior are fully dry before running the unit.

    Why Should You Worry About Mould In Your Air Conditioner

    How to Clean a Dirty Moldy Window Air Conditioner

    Not all moulds are created equal. Mould is a microscopic organism a fungus. There are good and bad moulds. For example, your camembert or brie cheese relies on mould for its distinctive flavour and texture. And where would we be without the wonder-drug penicillin? Its derived from a type of mould that scientist Alexander Fleming stumbled across. Unfortunately, the types of mould you might discover lurking in your air conditioning unit arent particularly friendly or useful ones. In fact, theyre much more likely to cause you harm than good.

    Mould spores are the mechanism through which mould reproduces. When your air conditioning unit is at rest, its the perfect petri dish for a wayward mould spore to grow on. Once comfortably at home in your air conditioner, a mould spore will reproduce. Further spores will be released and become airborne. Theyll spread throughout your home, landing on your food, your clothes and you. And from there youll eat them and breathe them in. If you have an allergic sensitivity to mould, its presence in your air conditioner is likely to trigger a significant reaction. Likewise, if you have asthma or any other respiratory illness, mould is a risk factor that can put you in hospital.

    Some moulds are also thought to be responsible for the production of mycotoxins, a leading contributor to serious and life-threatening illnesses such as pneumonia, particularly in children, the elderly and the immune-supressed.

    Apart from the styrofoam on your window air conditioner, your entire unit is also at risk of mold growth, especially the coils.

    When mold grows on the air conditioner coils, it can impede the efficient cooling of your air conditioner.

    The same is true if your unit is covered in dust and grime.

    In turn, this will lead to high monthly energy bills and warmer air conditioner air.

    It may even cause your air conditioner to cease functioning and require repair service.

    To get rid of mold development on your air conditioner coils, do the steps below.

  • Unplug the air conditioner from the power source.
  • Uncover the coils by removing the outer cover of the air conditioner. Use a screwdriver in case you need to unscrew the coil cover.
  • Use a vacuum to suck in loose dust and mold spores from the coils. Install a brush attachment to release more dust, dirt, and spores. Make sure that you move around the entire coil area.
  • Apply spray cleaner on the coils. This product is self-rinsing, which means you dont have to rinse your coils afterward.
  • Let the foam sit for 15-20 minutes.
  • Allow your air conditioner coils to dry before putting the cover back.
  • Secure the coil cover with screws and then reconnect the air conditioner to the power supply.
  • Mold growth on your HVAC system is disgusting.

    The spores can easily spread through the air coming from your air conditioner.

    Besides smelling musty, molds may also cause health problems such as breathing complications and allergic reactions.

    Finding The Right Professional

    When looking for a professional HVAC technician, its important to narrow your search to only licensed, bonded and insured contractors. This will ensure the company you choose to work with has the expertise to get the job done right and will stand behind the quality of their work. Always hire a reputable contractor.

Tak compressed air to blow dust out the back of the AC might also help. When not in use to keep it from becoming 22, some folks cover the AC area with a towel.

    2) Use Fan Mode to Dry the Inside of the AC: Several window ACs have a Fan option. The compressor won’t come on to transfer heat, but the fan will blow. Once you’ve cooled the room, turn on Fan Mode

    This will dry out the inside of the air conditioner – and since the EPA reminds us, moisture management is the key to mold control.

    If your AC doesn’t get much use, cleaning it once during the summers should be sufficient unless you or someone in your family is especially sensitive to mold.

    Turn Off Your Ac To Prevent Further Spreading

    Before cleaning your AC, you should first shut off the system. This will prevent mold spores from further circulating around your house. You need to unplug the system and visually inspect the unit to see if you have a mold problem. This will require you to grab a flashlight because mold may be further down the system. You need to be vigilant of the signs of mold, which can include streaks of green, black or brown stains. Occasionally, these stains will appear fuzzy. You also need to watch out for the development of mildew, which takes the form of white and powdery gray stains.
