How to Clean a Dirty Moldy Window Air Conditioner

Mold can grow in many areas in your home, particularly where it is dark and humid. So it should come as no surprise that air conditioners are one of the places where mold can be found. Unfortunately, AC units represent a particularly risky place for mold to grow, since they push air through the house.

This means that a moldy air conditioner will actually blow microscopic mold spores into the air you breathe, spreading the spores throughout the rest of your home. Since mold presents multiple health risks, its important to prevent mold from developing in your air conditioner, and to eradicate it if it does appear.

Detergent And Baking Soda

Similar to our laundry detergent method, this is a little more heavy-duty because of the added baking soda. All you need is one tablespoon of laundry or dish detergent, half a tablespoon of baking soda and one cup of water. Increase these ratios as needed.

  • Turn off the AC or heating.
  • Mix the solution in a large basin. Increase the ratios depending on how large your basin and air vents are.
  • Unscrew the air vents and submerge it into the cleaning solution.
  • Let it sit for 15 minutes.
  • Use a HEPA vacuum to clean out the inside of your air vents.
  • Use the same baking soda and detergent solution to clean out the inside of the air vents. You may need a long-handled mop to get deep into the vents.
  • After 15 minutes, use a scrubbing brush to scrub off the mold, mildew or dirt on your air vents.
  • Dry thoroughly.
  • Use a dry cloth to dry the inside of your air vents, too.
  • Once everything is dry, reattach the air vent.

    Mould, when left long enough, can also cause significant problems that will affect the efficiency of your air conditioner. In some instances, a build-up of mould can even lead to blockages within the air conditioning drains. The end result can be an expensive and inconvenient breakdown when you need your cooling system the most.

    Air Conditioner Featured Outside Of Home

    Leaving the air conditioning running in your home will not only cool your home, it will help remove moisture from the air and help circulate and filter the air.

    Question: In the process of selling my home, the buyers requested a home inspection. My problems started when the mold inspector reported elevated spores were four to five times the amount found outside. After paying a contractor to clean and treat for molds, the follow-up test showed the levels were even higher. The buyer refused to complete the deal. What made the mold grow so fast, and did we get ripped off by the contractor? A.N., Evansville, Ind.

    Answer: With a little investigation, I was able to gain some additional information about the sale of your home. It seems that soon after the initial inspection, the home was left vacant with the utilities off. The resulting enclosed dark and damp environment created an almost perfect situation for mold spores to grow.

    In the summer, a closed house with the air-conditioning turned off will have higher humidity levels than an air-conditioned home. A vacant house also receives little or no sunlight through closed shades and no air movement with the fan off and the doors locked.

    If you had simply left the air conditioning running, it would have cooled the home and removed moisture from the air and circulated and filtered the air.

    In my opinion, the remediation contractor failed you in that he did not warn you of the potential for recontamination.

    What Causes Mold To Grow In Air Ducts

    Mold grows in ductwork when two things are present: moisture and warm temperatures. A warm, humid environment has the ideal conditions for mold to form. A humid climate along with poor ventilation, or anything that traps moisture in your walls and causes condensation, can lead to mold in air ducts.

    Here are some of the HVAC problems that can contribute to these conditions and ultimately mold growth:

    If your AC unit is oversized for the space you have, one of the problems that it can cause is mold in air ducts. Larger units can cool small spaces too quickly and turn off before dehumidifying the air, leading to excess moisture. This moisture can build up in your rooms and ductwork. If you see mold shortly after a new installation, check to make sure youve got the proper sized equipment for the space you have.

    Setting your AC on a very low temperature can sometimes lead to mold around the vents. When the cool air from the vents meets the warm air in the room, the temperature difference can cause moisture in the air to condense on surfaces in and around the vents. If that moisture builds up and never gets a chance to dry out, it can lead to mold growth. This is called the temperature differential and usually takes about 20 degrees of difference for moisture to form. If you dont notice it for a while, the moisture can make its way into your air ducts.
