How To Stop Mold In Air Conditioner

Mold Removal Safety Tips

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

You wont know the full extent of the mold growth in your unit unless you remove it from the window. Grab some help to safely remove the AC and place it in a sturdy spot for cleaning, like the garage or outdoor work bench. Its best to remove the mold from air conditioner parts outdoors so you have plenty of fresh air to combat the mold and any fumes from the cleaner.

Why Should I Be Preventing Mold

Your health and wellness is the first and foremost reason that mold growth in your home should be taken seriously. Mold reproduces by making spores, small airborne particles that are easily inhaled by the human body. Once in the body, mold spores can cause anything from mild to serious health issues, such as:

  • itchy, watery eyes
  • increased respiratory illness
  • increased asthma attacks

While some types of mold may cause symptoms no more serious than that of the common cold or flu, other types – such as stachybotrys chartarum, or black mold – may cause life threatening health problems, or even death.

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.

Scrub The Moldy Areas Of The Ac

You need to get a sponge, brush or cloth to soak up the solution and scrub down the affected areas of your AC. You also want to clean the front grille with the same solution. Even if you do not see any mold, it may still be a good idea to scrub down the area just to prevent mold from growing in the future. You should allow the solution to sit for at least 10 minutes. After this time, you need to rinse the AC down with a damp cloth and water. If you still see mold on the unit, you can repeat the scrubbing steps until it goes away.

How To Detect Mold In Your Air Conditioner

When You Have Air Conditioning Mold, Let Specialists Help

Every homeowner should know how to spot mold in their cooling system. It may be difficult to detect that a problem is growing in your house. The more time

spent undetected the more time that the mold can spread, so be careful and check your units on a routine basis.

You can test for mold in your AC system by being aware of what to look for, and what smells occur in your home. Here are some signs that there may be some fungi lurking there:

  • A noticeable musty smell near the air vents in the indoor environment.
  • The distinct odor increases when the air is running.
  • Patches of black fungi are visible around the vents, evaporator coils, or drip pans.
  • You or your family have an irritated throat, nose, eyes, or sinus passage when the cooling is on.

Build A French Drain System

Building a french drain system is one of the most common ways you can push water away from the house.

If you dont know what a French Drain is, it involves digging a trench on the exterior sides of your home.


There are a few different ways in which the French Drain can be built. Sometimes it will be right beside the footing, other times it will be on top of the footing. This is something that your contractor will determine.

Once you dig the trench, you have to lay a pipe down and then fill it back up.

It can be more involved than that and it is not too very hard to do, but it is something better left to a professional.

What Are The Signs Of Mold In Air Conditioners

Its highly unlikely that you will notice black mold in your air conditioner until the infestation has reached a certain level. Common signs to look for include an earth-like, musty smell and flaring up of allergies whenever its in use. Also, its important not to run the system if you are reasonably confident that the ac unit is the source of the problem.

What Not To Do If Your Air Conditioner Is Mouldy

A strategically sprayed air freshener, scented candle or diffuser is only a band-aid solution to the problem of a mouldy air conditioner. It will only temporarily mask the odour caused by the mould. You need to eliminate the mould and the smell will go with it.

You shouldnt use generalised anti-mould sprays either, because they contain a toxic cocktail of chemicals. Theyll inevitably get into your air conditioning system and from there, become airborne. You, your family or pets will inhale the fumes and can suffer adverse health consequences as a result.

Other chemical cleaners on the market are caustic or corrosive and can actually cause long term damage to the inner workings of your air conditioner, shortening its lifespan and leaving you vulnerable to breakdowns. Thats why you should only ever use a product designed for air conditioners. Otherwise, you might void your warranty.

Why Should You Worry About Mould In Your 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.

Cheap and Easy Way to Kill Allergy Causing Mold from Air ...

It probably does not surprise you to hear that mold in air conditioner systems can make you sick. Most people are aware that exposure to household mold can cause illness. Whether the mold is in your air conditioner unit or in your home heating, ventilation and air conditioning ducts, it is a health hazard. And the truth is, if you have mold in your air conditioner, there is probably also mold in the HVAC ducts, since it’s all connected.

Mold in window air conditioning units is also a problem, since window units blow mold spores out into the room. A window unit isn’t connected to your home’s heating and ventilation ducts, though. At least initially, mold blown from a window air conditioning unit affects only the room in which the window unit is installed. Mold in a central air system, on the other hand, can easily affect the entire home.

These compounds can lead to serious health issues such as pneumonia and bleeding in the lungs. Mold found anywhere in the home can result in health problems, but when mold is in the air conditioning system, it can be particularly problematic. Microscopic mold spores become airborne when air blows through the ducts and then are dispersed throughout the home, where they can be easily inhaled or develop into new mold colonies. Infants, pregnant women, the elderly, and any persons who have an immune deficiency are most susceptible to mold-related illnesses, but even healthy, young adults can get sick.

What Causes Black Mold In Air Vents And Ducts

Mold in air ducts most commonly occurs when there is moisture inside the ductwork. As cool air flows through the vents on hot days, the moisture in the air can condense inside the air vent. You can see the same principle at work when you drink an icy beverage, and water beads up on the outside of the glass. When moisture is present, mold can flourish inside vents. The mildew can be introduced into the vents in several ways.

Mold spores are generally air borne, or spread through air. Spores can enter the duct work by simply blowing in from another area of the home, or from outside. The conditions need to be right for the spores to develop, however. A single mould spore can blow inside your home and begin to develop into a colony if the conditions are right. Warmer, moist environments are ideal for mildew spores to grow.

How To Clean Mold In Air Ducts

When cleaning and disinfecting ductwork, you will need to have a chemical cleaner. The most budget friendly, and also the most effective, solution to choose is a mixture of chlorine bleach and water. For each gallon of water you use, you will add one cup of bleach. Make sure that you can reach all the duct work or you may not eliminate the spores. It is important to know that you cannot simply remove the mildew using a cloth or mop. All the spores must be killed for the problem to be fully resolved.

In general, do it yourself mold removal in air ducts is a difficult task that may not result in the total eradication of the spores that are present. This is particularly true if you have insulated vents. Any insulated vents that you have will need to be totally replaced in order to kill the mold that is present in the home. You will also need to fully inspect the interior of the furnace or heating system, including the coils, to determine the root cause of the mold contamination.

Prevent Mold Growth Indoors

Mold grows indoors for a number of reasons. First, our homes are made up of organic materials that would normally be growing in the wild – wood and wood products, for example. Secondly, our homes often prevent fresh air from reaching all spots, and motionless spaces that collect humidity are prime locations for mold to begin growing. The magical ingredient for mold growth is moisture, and warm air is one of the ways water can move around your home.

Trapped humid air can begin to help spawn a mold colony in two ways – it can condense onto a colder surface or it can be absorbed into another material. However it travels, mold is an unwanted and dangerous thing to have growing in your home. Prevention is, as they say, nine tenths of the cure, and with mold this is equally as true.

Signs Of Mold In & Around Your Ac Venting

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.
