How to Remove Mold from Air Conditioner Ducts

As soon as you spot mold in your air ducts, you are facing a serious problem that should be addressed right away. While many homeowners may want to learn how to remove mold from air conditioner ducts themselves, this problem does not have a quick fix and requires professional assistance. A thorough and effective professional duct cleaning requires special antifungal cleaners. You may also need air conditioner repairs to correct what’s causing the mold. If you don’t address the underlying cause, then cleaning can only produce temporary relief. If you live in Pennsylvania, New Jersey, or Delaware don’t hesitate to reach out to the experts at Oliver for help.

Causes of Mold How to Remove Mold from Air Conditioner Ducts

As a fungus, mold likes moisture and warmth. Warm air penetrating the duct system can cause water to condense in an air duct. This can happen if a duct has a hole or a poorly sealed seam. If someone likes to set the air conditioner at a very low temperature, condensation can occur at the vents. The air ducts become chilled, but warmer air outside the vent creates the conditions for condensation.

An air conditioner normally produces condensation as it cools the air. The drip pan that collects the expected moisture empties into a condensate drain. A clog in the drain will cause water to collect and may create the right conditions for mold spores to grow.

Mold may also grow because of:

  • High humidity and poor ventilation
  • An oversized air conditioner

Mold reproduces by releasing microscopic spores. You can’t see the initial growth because it starts so small. Once mold patches become visible in your air ducts or around vents, you have an air quality problem. Moldy air circulating through your home can impact your health.

Red Flags for Moldy Ducts

You may notice a stale or musty odor filling your house when you run the air conditioner. The bad smell can range from mildly unpleasant to almost foul. If the smell goes away when the central air or heat is off, you have a sure sign of mold in the ducts. Even if an odor has not developed, the mold will continually release spores into your air. Symptoms of indoor mold exposure include:

  • Irritated nose and throat
  • Itchy eyes
  • Headaches
  • Nausea
