How To Get Mold Out Of Ductwork

Solution : Clean Your Evaporator Coil

BEST way to Clean DANGEROUS Mold out of Your Air Duct System – Twin Plumbing

The evaporator coil is an essential component of your AC unit and the main part that actually cools your home. But when it gets dirty, it becomes the perfect place for mold to grow. Follow these instructions to clean it out:

  • To start, youll need a solution of 10% bleach water. This is enough to kill off the mold without doing any damage to the coil system.
  • Most central air units have an access panel on the back. Take this off to expose the metal fins in front of the condenser coils.
  • Using your vacuum with the attachment brush, suck up any loose dust or debris from the fins and coils.
  • At this point, you can also straighten out any bent fins with a flathead screwdriver or a fin comb, which can be purchased at most appliance stores. Remove the finsthey will be held on with four to eight hex screws.
  • Now spray the bleach solution on the coils and wipe them down. Pull out the collection pan and wipe it down as well.
  • Reassemble the unit and run it to see if that has taken care of the musty smell.
  • Set Up A Negative Air Machine

    The negative air machine has something called a HEPA filter in it. Negative air allows all particles to be sucked into the HEPA filter instead of the particles just floating around in the air.

    The negative air machine can have tubes that hook up inside your ductwork to act as a vacuum to suck all dirt and debris right out.

    What Are The Dangers Of Moisture Buildup

    The number one concern of water inside the air ducts is mold growth. Under ideal conditions, mold spores can flourish within 48 hours. Mold needs only an organic food source, moisture and warm temperatures to grow. The air ducts provide all the necessary sustenance for a mold outbreak.

    Mold spores colonizing the air ducts are rapidly blown throughout the home via the vents. The spores become airborne, landing on furniture, carpeting and clothingwhich exacerbates the indoor mold problem. Indoor air quality is also reduced. Breathing mold can trigger health problems.

    Aside from mold growth, moisture inside the air ducts can reduce the insulations R-value. Over time, the water compresses the insulation, causing it to become less efficient. As the insulations R-value decreases, homeowners can expect higher utility bills and energy loss.

    Lastly, water damage to the walls, ceilings and roof can result from moisture inside the air ducts. Excess moisture can gradually be a cause of corrosion or decay in these materials. If left unaddressed for prolonged periods, the structural ruin can compromise the integrity of the building.

    Problem #: Clogged Condensate Drain Line

    How To Get Black Mold Out Of Air Ducts

    An AC condensate drain line.

    Do you see pools of water around your ACs inside unit? And do you smell that musty odor?

    If so, those symptoms point to a clogged condensate drain line. When condensation forms on your evaporator coil, it drops into a drain pan and exits outside via a drain line.

    But if your drain line is clogged because dirt falls into the pan then water stagnates in your drain pan, which facilitates mold growth.

There are these straightforward single-stage heating and cooling systems, and then there are the more sophisticated multi-stage HVAC technologies that can save energy costs. Over the last several years, HVAC systems have evolved into different types including zoned systems, heating systems, humidity control and cooling systems. Irrespective of the purpose that these systems serve, Mold can establish colonies inside the ductworks. This article will show you the correct way on how to get rid of mold in air ducts.

    According to the U.S. EPA, you should routinely inspect your HVAC systems, not just for mold, but for moisture. Look at drain and condensate pans to make sure they are draining properly. If they are plugged, the moisture that accumulates will become a mold factory.

    How Does Water Get Into The Air Ducts

    Moisture inside the air ducts is a common occurrence. A leaky roof or ruptured pipes can easily transfer water into the air ducts. The ductwork installed on the roof often lacks a watertight seal, which allows a pathway through the seams and into the interior ducts and vents.

    Moisture in air ducts can also be caused by the accumulation of condensation near the cooling coils of air conditioning systems. In such cases, condensation is expected. The air temperature inside the HVAC is cooler than the surrounding air, leading to a buildup of condensation.

    Newer, more advanced HVAC systems are fitted with mechanisms that extract excess moisture to prevent the possible destruction of the ductwork. Issues with condensation, however, can still arise due to incorrect HVAC installation, improper air duct service and malfunctioning systems.

    Flooding, too, can cause moisture to build up inside the air ducts. Across the US, flooding is a known threat during every month of the year. Flash floods, river floods, ice jams, snowmelt and dam breaks are causes of flooding. Rainwater is one of the most common causes of floods.

    When HVAC systems sit at ground level, the equipment is exposed to rising floodwaters. The coils, fans and chambers become dirty when infiltrated with floodwater. To re-use the system safely, the many parts and cavities require a professional air duct cleaning or replacement by remediation experts.
