How To Prevent Mold In Ac Ducts

Will Lysol Kill Mold

Sealing Ducts to Prevent Mold in the Attic

Lysol does have disinfecting products, including their mold and mildew remover spray. It eliminates mold and mildew stains, bleaches surfaces and kills 99.9 percent of viruses and bacteria.

However, this product is intended for bathroom surfaces, so use on air vents at your own risk. The manufacturer does state that prolonged contact with surfaces made from metal, old porcelain or plastic laminate can lead to discoloration.

You can try other Lysol products, such as a disinfectant spray. But these are intended to prevent mold and mildew, rather than kill it. It is better for odor, bacteria and viruses than anything else.

What Conditions Lead To Mold Growth

There are a few conditions that promote mold growth. Mold grows best between 77 and 86 degrees Fahrenheit, which is the temperature your air ducts are at when your home is being heated. It thrives in damp conditions and needs oxygen. It also needs food, which it has access to in your air ducts. Mold may make you feel nauseous or fatigued and can also cause or contribute to allergy symptoms.

Your Air Conditioning System Is A Breeding Ground For Black Mold

Unfortunately, your air conditioning system and your air ducts are a common place for black mold to reside. Moisture plays a significant role in the growth of mold. Your air conditioning system can act as an incubator for black mold because of its constant change in humidity levels throughout the summer season. If your air conditioner works as a dual heater as well, then it increases the likelihood of having a mold infestation at some point in time due to constant usage.

If you do have mold in your home and you use your air conditioning system, the effect can be the air conditioner moving the mold spores into your ductwork through the air, with those mold spores getting lodged into your air ducts. Once they make their way to your air ducts they will have a non-visible environment to grow.

How Do I Know If I Have Mold In Vents

You may be able to physically see mold spores growing inside your HVAC air ducts. Take the vent cover off and visually inspect the inside of your vent with a flashlight. Look for dark black dots.

What Causes Black Mold In Air Vents And Ducts

Mold in Your HVAC Ducts? How to Get Rid of it and How to ...

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.

Will Air Duct Cleaning Prevent Mold In My A/c

Air duct cleaning is a great way to remove dust from your HVAC system in order to minimize the chance of mold growing inside. And if you already have mold, duct cleaning will remove the mold from your central air conditioner.

Air duct cleaning is the process of connecting a heavy duty vacuum to the air ducts. The large vacuum is sometimes outside as part of a truck, or it may be a portable vacuum inside.

A large diameter hose, such as 12″, is connected to a return duct — and then the ducts are cleaned using compressed air tools or brushes. When the vacuum is turned on, it creates a significant negative pressure in the duct system, so that when dust is loosened within the ducts — it all gets sucked to the vacuum.

If you have your air ducts cleaned, it is important that they also clean your indoor air handler or furnace. This is the central area where all the air in the home goes through, this is also usually where your filter is located . It is important to clean the blower fan, the evaporator coil, the furnace housing — the whole unit.

Almost always, if I find mold in a house, it is usually at the indoor air handler.

Why Do I Have Mold In My Vents

It can get humid inside your vents, which is the perfect environment for mold spores to grow. Vents in rooms that arent well-ventilated are the most susceptible to mold.

Air conditioners are another culprit. If theyre too big, excess moisture in the air vents doesnt circulate properly. And if you keep the temperature too low, expect condensation to form due to the temperature difference.

Install An Air Purification System

How to reduce mold in your air duct system. Great Tip.

Installing an air purification system can be a great way to help prevent mold in air ducts and reduce the frequency of cleaning required.

Air purifiers work by drawing air through filters which trap tiny airborne particles including dust, smoke and mold spores. Cleaner, fresher, better smelling air is then circulated around the room. This can also have a big impact for any allergy sufferers.

    Where Does Mold Grow In Heating & Cooling Systems

    There are three primary locations where mold growth typically occurs in HVAC systems: the air conditioners indoor unit, the drain pan, and the ductwork. These locations can foster mold growth by providing the spores what they need: moisture, food, and warmth. Food for mold can be something as simple as dust, which is why it can pay to keep your system clean.

    How To Eliminate Mold

    Mold cannot grow in environments that lack moisture. If you get rid of the moisture, youll keep the mold from growing. In HVAC systems, moisture occurs due to the mixing of hot and cold temperatures. Its the same reason cold beverages sweat and create condensation. The difference between the two situations is that condensation on air conditioners happens for a long time.

    When looking for causes and cures for mold growth, you should ask two primary questions:

  • What is causing water to form?
  • How do I eliminate the water/moisture?
  • How Mold Enters An Air Duct

    Mold inspection and testing blog and research orange county

    Mold typically enters an air duct system any time steady amounts of water or condensation are present in the vents. If an air conditioning unit is infected with a strain of mold, oftentimes it will spread from the air conditioning unit throughout the air duct system. If there is a low spot in your ducts where moisture can pool, then you can bet that mold will eventually be attracted to it. Think about your air ducts, they are the perfect spot for mold to thrive without being stopped, it’s dark, untouched, and if it’s there, it’s growing off the whatever moisture is still occurring.

    The best way to prevent mold from growing inside of your air ducts is to keep the ducts as dry as possible and have them regularly cleaned and checked by experienced technicians so that dirt, grime, and other water trapping substances are not present within the airways.

    If you are looking at the moldy spots near your vents with frustration, here is how you can channel that rage toward tackling that nasty infestation.

    First, remember that mold can be dangerous. You need to don the proper PPE when handling mold problems.

    This means:

    • Industrial grade gloves
    • Safety goggles

    You may even want to invest in a painters suit that you can dispose of after finishing. Next come the tools of the trade. Keep in mind: whatever you use to clean mold, you will need to throw it away. If you dont, you could be inviting mold right back into your home.

    You will want a soft brush and some rags to do the dirty work. You can use a few cleaning solutions to tackle mold. The first is a home remedy.

    • One tablespoon household detergent
    • Half tablespoon baking soda

    Invest In A Dehumidifier

    The battle against humidity can be a constant war, which is why buying a whole-home dehumidifier is the perfect battle tactic. Dehumidifiers are the ultimate weapon against excess moisture and can help prevent any mold from creeping into your home.

    Small portable dehumidifiers can only take out the humidity in one area. Still, a whole-home unit works with your HVAC system to help control the moisture throughout your entire home.

As such, if theres water vapor in your air ducts, then mold may form inside, using dirt, dust, and other debris as its food source. Water vapor can develop when cool air passes through the system and ducts and if water vapor outside of the ducts forms water droplets.

    What Does It Mean When Condensation Forms On Your Air Ducts

    Even the most efficient air conditioners create some condensation. As your HVAC system pushes cool air through the ducts, they get cold.

    The temperature in your attic or crawl space is usually much warmer than the ducts when the cold surface touches the warm air, duct condensation forms.

    If your system is running efficiently, you should not see much condensation. If there is an excessive amount of water on your ducts, it could be a sign of:

    • Airflow restriction
    • Humid air in your home
    • Dirty air filters
    • Warm air in your attic
