Mold in my central air conditioner.

Mold can be one of the negative effects of floods or can indicate a problem with your air conditioning system. Mold does have a tendency to grow inside air conditioners that sit unused for a while. You might notice mold in the air conditioner when performing routine maintenance like when cleaning or replacing the filter or removing debris from around the evaporator coils. It s likely that mold developed in the unit over the winter and you didn t notice it until you turned on.

Molds thrive when the humidity levels exceed 70 percent. One of the first signs that black mold is growing in your air vents is a distinct musty mildew like smell in specific rooms or even throughout your entire home. When black mold grows on walls floors carpets and so on it s relatively easy to spot. When mold grows within the central heating cooling and ventilation system there are high chances that every room connected to the vents receives generous amounts of mold spores.

Secure ducts check the ducts in the basement or attic for leaks while the blower is on. Mold spores naturally traveling in the air attach to damp areas then begin to grow. I often find mold on the exterior of air conditioning systems more often than the interior. As soon as you switch your heater or air conditioner on the microscopic particles start floating and blowing out with air into the room.

The outside of ducts more often than inside. Allow the solution to sit on these surfaces for approximately 10 minutes then rinse with water and a damp cloth. Mold is common in environments that have dirt dampness and darkness. Also clean the air conditioner front grille if it has mold on it.

Here are some common reasons that could be causing a mildew odor to develop in your ac. Reassemble the air conditioning unit and plug it back into its power source. 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 air is leaking out it also means that moisture is leaking in and forming mold within the ducts.

Let the unit filter grille and metal cover dry completely. Moisture is the building block for mold and mildew growth which can cause a musty smell from your air conditioners.
