How To Clean Mold From Central Air Conditioner

Evidence Of Mold In Your Home Air Conditioning System

How To Clean Mold From AC Vents: Cleaning Mold From HVAC Vent

Because its so dangerous to have mold growing in your home, you have to be vigilant to spot signs of mold in your A/C equipment. Mold has a tendency to hide in most components of air conditioning systems where it isnt always easy to see. More importantly, if mold spores never actually sprout, you may not be able to detect them at all with the naked eye. The best way to know if your air conditioner, ventilation system, or general living environment are affected by mold is to have a certified HVAC company take a look.

HVAC professionals have the skills and necessary experience for identifying mold problems even when mold spores remain microscopic. Understanding this, you should still be on the lookout for the following indicators of mold development:

Is Mold A Problem In Your Home

If mold seems to plague your home, theres a problem somewhere.

Your Central AC System If you have central air conditioning, mold can build up in your ducts. This is especially true if your ducts are the wrong size and/or if your AC or heat pump is the wrong size. These issues might not allow the dehumidification process that goes with air conditioning to be complete enough. Water condenses on cold, dusty ductwork sheet metal, and mold spores have all they need to grow.

We highly recommend having the system looked at by an HVAC professional. Getting two opinions about what the problem is and how to solve it is a good idea.

Your Home or Building You should definitely try to eradicate mold in your home or building. If thats not possible right now, or until it is done, an air purifier designed to remove mold spores from the air is a good short-term solution. Once the mold has been removed, the air purifier will keep your air cleaner and more breathable.

How To Spot Black Mold In Your Air Conditioner

Is black mold in an air conditioner dangerous? Yes, so it is crucial to know how to spot it in your house.

Unfortunately, many people dont realize they have black mold in their house until they are sick. Below are some common signs to be aware of that could indicate black mold in your air conditioner unit.

How To Get Rid Of Mold In Your Hvac System

Despite regularly inspecting your system, you are still getting complaints about the smell , 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. If vacuuming dry coils, use a HEPA vacuum.
  • 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.

    How To Prevent Mold In Air Conditioner

    Fortunately, there are a few steps you can take to prevent mold from developing in your air conditioner:

    • Reduce moisture. The easiest way to avoid moisture build-up in an AC unit is back when you purchase it. Look for an AC unit with humidity control. Many modern units vent water vapour with air. If you have a unit that is designed to collect water in a reservoir, empty it regularly.
    • Avoid organic debris. In addition to water and air, mold needs organic matter to breed. Clean or replace your air conditioners filter regularly, and vacuum the interior to clear out any dust and debris. Dont give mold any food to live on!
    • Keep unit running while on vacation. Mold tends to build up when the air conditioner is not running and the air is still. Keep your unit running, even when on vacation. To reduce energy consumption, you can set the target temperature higher so it runs less often, but dont shut it off altogether.

    Unfortunately, air conditioners represent a particular problem area for mold, since they push the air and mold spores through the house and into the air you breathe. The risk of black mold in particular makes it important to be vigilant about mold in air conditioners and nip problems in the bud.

    It may feel intimidating, but dont feel discouraged. Knowledge is power, and knowing to keep an eye out for mold in your air conditioner will help you keep your home healthy and happy.

    How To Detect Mold In Your Window Air Conditioner

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

    Most homeowners expect to discover mold in basements, leaky areas around roofs, and under carpets that are old or that have gotten wet at one time. But, not many are aware of the danger that lurks inside their air conditioner.

    The first sign of mold the homeowner typically recognizes is a musty smell that fills the room often without the visual detection that there are active mold spores present. Mold in a home can lead to serious health issues and it doesnt take long for the symptoms to begin.

    If you continue to smell this odor, rest assured there is mold somewhere in your home. However, if the smell is stronger when you turn the unit on, chances are there is mold growing in it somewhere, even if you are unable to find where at the time.

    Extensive mold removal and repair cost can accumulate just as fast if the mold isnt detected early. If the discovery of mold is early enough and prompt action is applied, the homeowner can get a handle on the danger before it progresses too far.

    Chances are you will be able to see mold in your AC if you make a thorough inspection or if you remove the filter and examine it, there could also be visible traces there. Even if it is too soon to see active mold on or around the filter, yet the smell it there, do a detailed inspection of the coils and around the motor for any signs of onset growth activity.

    What Causes Mold In Your Air Conditioning Vents

    Pin on Your Air Specialist

    As long as theres moisture and the temperature is warm, molds will form in the air conditioning vents.

    Here are the common causes of mold on AC vents.

    Climate, Moisture & Humidity

    The main ingredient for mold formation is water vapor. And, in a humid climate, theres usually moisture in the air, which gets trapped in walls. The condensation process then happens, causing mold to grow on the air conditioning vents.

    Poor Ventilation

    Imagine air trapped in a house where theres poor ventilation. The moisture trapped in the walls will soon become stale since it cant escape, and in no time, there will be a musty odor.

    The stale moisture then forms mold around the AC vent in the bathroom and other damp places.

    Oversized AC Unit

    If theres one thing we encourage as HVAC professionals, every homeowner should install a suitable AC unit for their space. Theres always the correct size for every room.

    Installing an oversized AC unit in a small space encourages mold formation. Such AC will provide quick cooling but will turn off before removing the excess moisture from the house. This moisture will then cause mold in the air conditioning vents.

    AC Is Being Run Too Cold

    Low temperatures can also cause mold formation in the air conditioning vents. When this too cold air mixes with the rooms warmer moisture, condensation happens.

    This moisture build-up, in return, causes mold to grow in the AC vents.

    Symptoms to watch out for that may be linked to mold growth in your home include:

    • Aggressive coughing

    Everything You Need To Know About Dealing & Preventing Air Conditioner Mold

    Prevent Future Mold Growth

    There are several things you can do to stop mold from growing in the first place after you have cleaned your unit. First, you should leave your AC on at all times.
