How Do You Clean Mold Out Of An Air Conditioner

Effects Of Mold In Your Ductless System

How to Clean a Dirty Moldy Window Air Conditioner

We touched on a few effects that mold in your ductless system can have on you. But, those scratch the surface. If you leave a problem like this untreated, it will spread throughout the house. And, youll feel worse and worse. The more spores you inhale, the more severe the symptoms: headaches, trouble concentrating, even memory loss. Meanwhile, you dont want it to spread. Mold itself wont cause any structural damage. But, it also helps breed fungus and other invasive things. Those can eat away at walls and rafters if left untreated. Now, its important to understand that spotting a little speck isnt the end of the world. The truth is, we all have at least some mold in the house. In fact, any black spots on your bathroom tile grout or shower curtain are mold. There are many strains of mold out there. Most are relatively harmless, especially in small quantities. Still, you dont want to let the situation get out of control. After all, you clean your bathroom regularly, right? In the same way, you want to stay on top of any problems with your ductless heat pump systems. Unfortunately, these components can cultivate mold quickly if you dont use them properly.

How To Clean Mold From Air Conditioner Ac Coils

Do you know how to clean mold from air conditioner AC coils and why should you attempt to clean off mold from air conditioner coils? Allowing the mold to continue spreading and growing poses a health risk. If there is mold on the air conditioner coils, mold spores can easily spread through the ducts in your ventilation system.

Mold spores can cause a variety of health complications. Exposure to mold may experience an inflammatory response to the mold, especially if you already suffer from asthma, allergies, or a weakened immune system.

You may experience coughing, throat irritation, nasal congestion, and sneezing. Respiratory problems are also common. The mold spores may also exacerbate asthma and allergy symptoms.

Allowing the mold to remain on the coils also poses a danger to your air conditioning system. The moist mold can increase the corrosion of the copper coils, eventually resulting in a leak. Luckily, you can avoid these dangers by using the following steps to clean mold from the air conditioner coils.

Cleaning The Ac Unit To Remove The Molds

Cleaning your ac units is actually very simple and does not require you to have any technical knowledge about the operation and functioning of the units. You only require opening the unit and removing the filter so that you can be able to access the condenser. You should spray the unit with clean water and let the water stand in the unit for about 15 minutes.

You should then use a very clean cloth or piece of towel and wipe off the water. In order to be able to dry the unit completely, you should use a vacuum cleaner in order to suck the water particles from the unit. It is important to spray the unit carefully so as to prevent water from getting into contact with the fan in the unit.

Use a brush to dust off the condenser and the filter. You should also use a fairly rough piece of clothing to clean the fan and the blades on the fan. You should then use a vacuum cleaner in order to suck all the dirt and dust particles that may be hidden in the unit. These are particles that can not be wiped off manually.

The water base in the unit should be extensively cleaned due to the fact that this is the part that holds much of the standing water in an air conditioner unit. After extensively cleaning the unit, you should then give it time to dry completely. After the unit is completely dried, it should then be reassembled. It is important to accord your unit regular cleaning in order to maintain its high performance standards and efficiency.

Do Portable Air Conditioners Need To Be Drained

In most cases, your portable air conditioner will not need to be drained. Edgestar, Avallon and Koldfront portable air conditioners use a condensation exhaust system to expel water vapor collected during the dehumidifying/cooling process. This moisture is released through the exhaust hose along with hot exhaust air.

How Does Mold Growth In Air Conditioners

How To Eliminate Mold From Your Window Air Conditioner ...

Mold spores are literally all around us. They are constantly floating through the air and landing on sold surfaces. In nature, when those spores land on organic matter, such as fallen trees and leaves, they grow and feed on the matter, aiding in decomposition hence, outdoor mold growth is actually quite beneficial. Of course, mold spores get inside, too. The microscopic spores float inside through windows, doors, chimneys, and ventilation systems. They can also attach to shoes, clothing, bags, and anything else that goes outside, and when those items are brought back inside, they become airborne, travel throughout your house, and land on all types of surface.

Try as you might, there is no way to completely eliminate mold spores in your house. Minimal concentrations of mold spores usually arent problematic the problem arises when those spores continue to multiple and become mold. Why? Because patches of mold release spores, and the concentrations of the spores that mold growth produces can be quite high. Thats where the problem lies, and where adverse health effects as a result of mold exposure can occur. Since it is impossible to stop mold spores from entering your house, in order to prevent the negative effects that mold exposure can cause, you need to work on preventing the spores from growing into the fungi.

In order to grow, mold needs just a few basic things:

  • Moisture
  • Food
  • Dimly lit conditions

Mold In The Hvac Ductwork

While the mildew on the HVAC vents does not present an immediate health risk, the possibility exists for an underlying issue within the ductwork itself.

The ductwork is the vehicle used to move air from the air conditioning handler to the living space.

So, when the duct board becomes contaminated with mold, the possibility exists that the air in the home can as well.

Mold spores and fragments can be distributed into the air and landing on surfaces as well as into the carpet leading to potential health risks.

In addition, the air can push out the mold from the ductwork onto the grill.

If you see mold in the air conditioning air ducts, it is recommended that they are cleaned by a licensed HVAC professional as an unclean system that can affect the overall air quality within the home.

Is Mold On Air Conditioning Vents Dangerous

Mold present on air conditioning vents is unlikely dangerous because the material is usually metal or plastic, which is not porous. Because the vent itself is non-porous, the mold will be on the surface of the register grill only and not present danger.

Cleaning Black Mold From Air Conditioning Vents

Because vents are not porous, black mold in which the scientific term is Stachybotrys does not grow on vents. The mold that may be present on a vent is not generally toxic but can cause an allergic-type reaction such as coughing or sneezing.

However, just because mold is not dangerous when present on the vents, it does not mean mold inside of the vents cant cause occupants in the home harm.

How Mold Grows In An Ac Unit

Knowing the science behind how mold grows is helpful when trying to understand how to prevent mold growth.

In order for mold to grow, it must have both moisture and nourishment .

Moisture comes from within the AC unit, where water leaks and spills are common, and dust is molds most common food source.

So, when you leave the air conditioner off while youre out of the home, dust builds and settles within the unit, along with any moisture/humidity that manages to accumulate within the machine. This creates a heavenly environment for mold.

Cleaning Mold From A Wall Or Window

These air conditioner mold removal steps will work on most window or through-wall air conditioners as well as on wall-mounted split system air conditioners and heat pumps.

A split system or “ductless” air conditioning system dispenses with duct work entirely, using a wall-mounted indoor evaporator/blower unit and a separate outside compressor/condenser .

At above left you can see rather typical dark mold growth on the plastic surfaces of the indoor half of a wall-mounted split system air conditioner. Similar mold may appear on window or through-wall mounted air conditioners as well.

Mold grows readily on the plastic surfaces of the air conditioner’s face cover and on its air-directing louvers because these surfaces often are damp with condensate from the conditioned air.

Mold may also grow on the metallic surfaces of the squirrel cage fan that blows room air through the air conditioner, more so as those surfaces accumulate building dust that typically includes organic debris such as skin cells.

At left is a close-up of a fairly-clean split system air conditioner blower fan.

If you click to enlarge the image you’ll see normal dust accumulation on the blade edges. In contrast, if the curved blades have become dust-laden not only does that serve as possible mold food it also means that the air-flow of the blower fan will be reduced.

Below is a fairly dirty air conditioner air outlet grille or fan blade.

  • Filters and grates of air conditioners should be frequently cleaned to prevent dust accumulation, which can serve as a food supply for mold and inhibit airflow.
  • Air conditioners must be emptied regularly. They usually have a light and an automatic shut-off to indicate that the reservoir is filled. Therefore, before storing your portable AC for the winter, ensure it is dry and empty.
  • Replace your air filters frequently. Blocked filters not only serve as a food supply for mold but also can obstruct air circulation.
  • Air conditioner ducts usually have self-regulation of moisture sin the circulation of air dries them out. It would be best if you kept all your air returns and grates clean and unblocked to enable proper air circulation with your HVAC system.
  • Never should you introduce moisture to your air conditioner. When duct cleaning, use dry wiping or dry vacuuming.

Mold growth around your air conditioner is a serious issue since it enables the spread of mold spores across your home. Fixing an HVAC mold issue can be a challenging and costly job. for more information about HVAC mold issues.

Air conditioner vents can be breeding grounds for black mold. Condensation forms in the coils and ducts as cool air circulates through the system, creating a habitat for moisture-loving mold. Black mold can cause severe respiratory symptoms, particularly in people who are allergic to mold. After you clean your air conditioner vents, inspect walls and insulation to find the source of the black mold infestation.

  • Wear long sleeves and pants and put on a high-efficiency dust mask to protect yourself from black mold spores. Make sure all household members with mold allergies or respiratory problems are out of the house before you begin to clean the air conditioner vents.

  • Remove the vent cover of a window air conditioner by unscrewing the screws with a screwdriver or pressing in on pressure clips. Place the vent cover in a basin or tub, sprinkle with laundry detergent and add enough water to cover the vent cover. After 15 minutes, rinse and allow the filter and vent cover to air-dry.

  • Remove dust from the inside of the air conditioner, as the dust in the moist environment allows mold to thrive.

  • Spray the blades and duct opening with water to prevent dry mold from escaping into the air. Wipe the blades and duct opening as thoroughly as possible with soapy water. Mold spores are microscopic and not visible to the naked eye, so clean surfaces even if you do not see mold.

    How To Get Rid Of Mold

    Despite regularly inspecting your system, you are still getting complaints about it , here are some tips you can share with your HVAC contractor for cleaning it up:

  • Turn off your HVAC system.
  • Everyone involved in this cleaning should wear at least an N-95 respirator
  • Replace anything porous, such as filters or insulation that has become wet. Double-bag the waste using 6-mil or thicker plastic bags.
  • Use wet vacuums to clean out any standing water.
  • Use an EPA registered disinfectant labeled for HVAC use to clean non-porous surfaces of mold, mildew, and other dirt. BIOSPRAY-TOWER ready-to-use disinfectant and mold cleaner will kill and remove mold, mildew, and odor-causing bacteria.
  • Clean the HVAC evaporator coils using a mechanical coil cleaning system to remove any solid debris.
  • As an added measure, isolate each section of ductwork you clean with bladders so the spores you stir up during cleaning dont spread to other parts of the system or the building. Fog the area with an EPA-registered disinfectant.
  • Apply a mold and mildew inhibitor to all components of the HVAC systems. Again, this must be EPA registered and specifically labeled for use in HVAC systems to limit risks associated with using the wrong chemicals and cleaners in HVAC systems. BBJ Mold Control is EPA registered for use in HVAC systems to control mold growth for up to 2 years.
  • As a final step, HEPA vacuum anything that you cleaned up.
