Does Air Conditioning Prevent Mold

If You Use Bleach To Clean Up Mold

Tips To Prevent Mold In AC Air Conditioning HVAC
  • Never mix bleach with ammonia or other household cleaners. Mixing bleach with ammonia or other cleaning products will produce a poisonous gas.
  • Always follow the manufacturers instructions when you use bleach or any other cleaning product.
  • Open windows and doors to provide fresh air.
  • Wear rubber boots, rubber gloves, and goggles during cleanup of affected areas.
  • If you need to clean more than 10 square feet, check the U.S. Environmental Protection Agency guide titled Mold Remediation in Schools and Commercial Buildings, which gives advice on all building types. You can get it by going to the EPA web site at .

What Causes Mold To Grow

According to the Centers for Disease Control and Prevention, mold grows in places with a lot of moisture. It can enter the home through doors, windows, and vents, or it may be brought in from the outside by people and pets. Once inside, it can grow on almost any type of material, including wood, tile, fabric, and more.

Chances are, you have mold in your home. It is impossible to eliminate mold, but the key to prevention is managing moisture. If mold lands on a damp or wet area, it will multiply.

You can identify mold growth by sight and smell. It may smell musty and look like dark green, yellow, brown, black, or gray spots. If you are wondering how to prevent black mold, there are ways to test for mold type, but regardless, you should remove any mold as soon as you are aware of it.

S To Take To Confirm The Presence Of Mould In Your Air Conditioner

You should inspect your air conditioning ducts and inside the unit itself for visible signs of mould. Mould can also be located on the air conditioning coil, the drain and on the fan itself.

If you suspect youve got a mould problem, you can also arrange for professional testing to confirm its presence and what type of mould it is. This can be done via a spore count. Its effectively an audit of the number of airborne mould spores and the collection of a sample for laboratory analysis.

Mold Can Make You Sick

According to the Centers for Disease Control and Prevention , mold can cause the following ailments in people:

  • Congestion
  • Eye problems
  • Shortness of breath and fever

Its important to note that not everyone who comes into contact with mold will have these health problems, but those who are sensitive to mold could have the following reactions. These health risks can be serious, making mold prevention in your AC a big deal.

What’s The Bottom Line On Preventing Mold In Your A/c

Did You Know That Air Conditioning Vent Cleaning Prevents Mold?

If you ever have mold in your a/c system, or seen an air conditioner with mold, then you know that doing everything possible to prevent mold growth is a priority. We discussed having your air ducts periodically cleaned, installing a UV light, and making sure that the condensate is properly draining away from the indoor unit.

Besides this practical ways to prevent mold growth, probably the most important thing you can do is open up the cover to your indoor air handler or furnace once in a while just to make sure there isn’t any mold growth or other problems.

Also, once in a while, take a flashlight and inspect your air vent covers in each room of the home. If you ever see a black mold-like substance, there is a good chance that there is mold in your indoor air conditioning unit. During my home inspections, those are really the only two locations that I see mold growth within an air conditioning system.

Regular Maintenance Is Important

Regular maintenance is key to ensuring your air conditioner is doing its job, maintaining the air quality as well as assisting with mould reduction in your home.

Neglecting to regularly clean and replace filters, can prevent your air conditioning system from working efficiently and effectively and can lead to mould growing on dirty and clogged filters, as well as inside the air conditioner fan coil.

At Coolcene, we recommend regular scheduled maintenance services be carried out on your air conditioner. Ensuring your air conditioner is operating optimally, will assist with the prevention of mould in your home as well as increase the energy efficiency of your air conditioner. to book a maintenance service

Use Detergent & Baking Soda

Detergent and baking soda is a more powerful version of killing mold than using laundry detergent. Below are the steps you should follow.

  • In a basin, add one tablespoon of either laundry or dish detergent, one cup of water, and a half tablespoon of baking soda.
  • Unscrew the AC vents and put in this solution. Note: the vents need to submerge in this solution fully. If they dont, increase the ingredients in the same ratios I specified above.
  • Let it soak for 15minutes. Meanwhile, use a HEPA vacuum to clean the inner parts.
  • Once vacuumed, use a long mop to wash the interiors using the same solution.
  • The next step is to apply a scouring brush on all the parts to remove any remaining debris and leave them to dry before reattaching the air vents.

    Toggle On The Humidity Control

    Humidity is a significant driver of mold growth- if the humidity in the room is high, mold growth will be accelerated.

    To prevent a moldy mess, youll need to keep the humidity level in check. Not every window AC unit comes with a humidity control, but many of them do.

    Look at your AC unit closely and see if there is a humidity setting. If your AC is equipped with humidity control, turn it on and set the humidity level to 30-50%.

    This humidity level is perfect, as it will keep you comfortable without encouraging mold growth.

    If you havent yet bought an AC unit, make sure that you purchase a model that allows you to control the humidity setting.

    Fog The Air Ducts With Plant

    How to prevent mold in window air conditioner

    Another technique that helps to prevent mold buildup within an a/c system is to periodically fog the duct system with a breathable anti-microbial spray. You want to make sure that the disinfectant is breathable, preferably plant-based, and is safe to use. Black mold in an air conditioner is known to be related to numerous diseases.

    There are cold fogging machines on the market that you can purchase for homeowners. You simply pour the disinfectant into the fogging machine, plug it in, and point the spray nozzle at one of your return ducts for a few minutes.

    You will want to first make sure the a/c is on so that the mist will go throughout the entire duct system.

    If you actually own the fogging machine, you can easily fog your air ducts once every few months, or even once a year.

    If you have any doubts about using a fogging machine, it would be best to contact a qualified air duct cleaning company.

    Think About What Causes Mould In Air Conditioning: Moisture

    To work out how to fight mould in air conditioning systems, its useful to know why its there. Fortunately, this is not hard! All sites of mould growth are likely to share one thing in common: moisture. Moisture is the basic building block of mould. Without moisture, mould simply cannot thrive. And where better to find moisture than in an air conditioning system? Your air conditioner is full of moisture and airborne mould spores. That is largely unavoidable too, as the operation of your air conditioner involves the circulation of air from outside your home. It also involves the condensation and evaporation of moisture. So, inevitably, the airborne spores and moisture combine. The result: mould! But if this is unavoidable, how can you fix the mould? Read on to find out!

    Tips To Further Prevent Mould

    Investing in an efficient air conditioning system for your business premises can go a long way to keeping your indoor environment comfortable, fresh and mould-free. However, there are a few extra things you can do to help keep your building mould free:

    • Try and keep the temperature up although you may think taking away warmth would make it harder for mould to grow, colder temperatures just encourage water to condense across your workplace, creating more damp for mould to grow on.
    • If you notice any leaks across your premises whether thats from pipes, through your ceilings or walls get these sorted as soon as possible. Water ingress can lead to problematic mould but can also cause structural issues, so this should be fixed quickly.
    • If you have carpeting, damp shoes can track moisture throughout the office, encouraging mould growth. Make sure you have carpets regularly cleaned, or consider replacing your flooring.
    • If youre going to be leaving the premises empty for a while, it can pay to run your air conditioning on a timer while youre away to ensure stagnant air and lingering moisture doesnt mean you return to pesky mould.

    Whats Better For Mold Air Purifier Or Dehumidifier

    Can you tell me the difference between an air purifier and a dehumidifier for mold? A dehumidifier is the best device to use if you have mold. Excess water in the air can cause mold to grow. The root cause of the problem cant be fixed by an air purification device.

    Causes Of Mold Growth In Acs

    Mold Prevention

    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 Is The Best Humidity Level To Prevent Mold

    Humidity is one of the most important factors a homeowner should take into consideration when thinking about their indoor comfort. While temperature gets all the attention, humidity can have a greater effect on your health and day to day life. For example, think about a hot summer day: which is more preferable, a hot and humid one, or a hot and dry one?

    Humidity is important when it comes to mold growth in your home as well. Cold air holds less moisture than warm air, which is in part why air conditioning prevents mold growth. A hot, humid house means that theres lots of vaporized water particles in the air, and airborne water can move around in ways that liquid or solid water cannot.

    To keep indoor moisture under control, we usually recommend a indoor humidity of 50%. There are inexpensive humidity monitoring devices on the market that can help you identify when your humidity might be too high – if you notice theres an ongoing problem with high humidity, its important to figure out why and take measures to solve the problem.

    Can Mold In The Ac System Make You Sick

    Mold growth can be a scary problem for homeowners. It can wreak havoc on the house and also on your health. This is especially true for anyone who is sensitive to molds or has mold allergies. If the fungi is allowed to grow throughout the HVAC system, the ducts then carry spores into every vent in the house. With spores blown around, you and your family are constantly inhaling them.

    This exposure can cause inflammation through your airways and lungs. Breathing it in can exacerbate respiratory problems, shortness of breath, skin irritation, allergies, and asthma symptoms. Common problems range from coughing and sneezing to bronchitis and allergic reactions. Some people notice rashes, itchiness, hives, a runny nose, watery eyes, headaches. Less common symptoms include fatigue, nausea, and dizziness. Some reactions can even be life-threatening.

    Ac Units Spread Mold Efficiently Through Your Home

    We dont want mold anywhere in our homes, and mold has the potential to be dangerous whether its on your walls or behind the toilet.

    But when its in the AC, it gets blown all over your house, increasing the chances that youll come in contact with it on a regular basis.

    Even though for some, the cleaning steps above may seem too involved, the health of your family is worth the trouble.

    Management Of Ac Ductwork And Equipment Mold Factors

    Preventing &  Repairing Mold in Your AC

    What can be done to manage these areas?

    Replace your air filter regularly and ensure that it seals well in the filter track to prevent air bypass. Filters with higher dust removal efficiency are available from numerous sources including your AC service center. When upgrading your furnace filter, beware that a higher performance air filter makes your furnace work harder to circulate air through the building. Ensure that installation of the better filter does not reduce furnace air flow to a level that limits adequate cooling of the building. Consult with your service provider if guidance is needed.

    The condensate drain pan is usually accessible for cleaning and removal of deposited organic material, and biolfilm. The drain pan piping should also be cleared of any dirt or biofilm buildup that might obstruct the free drainage of water from the pan. Air circulation blowers, cooling coils and other hard non porous surfaces can be cleaned periodically to remove the accumulation of organic material. Thorough cleaning of these areas is likely to require the support of a professional cleaning service.
