How can I clean mold behind AC unit?« Back to Previous Page

After the heavy rainfall we had last month, I noticed a persistent mold growth behind the central air conditioning unit in our bedroom. It's been there for at least two weeks now, and it smells awful and seems to be causing my allergies to flare up. The AC unit is located on an exterior wall of the master bedroom. How can I effectively clean this area to prevent the mold from coming back?

Cleaning mold behind your AC unit can be a bit tricky and it’s important to do this properly to prevent the mold from coming back. Here are some steps you should follow:

Firstly, ensure that you have a good understanding of what's involved as per UAE regulations. In Dubai, it is crucial to follow guidelines set by the Environment Agency – Abu Dhabi (EAD) for handling and disposing of mold-contaminated materials.

Before starting, make sure to turn off the AC unit and remove any visible debris or dust from around the unit. Wear protective gear like gloves and a mask to protect yourself during the cleaning process. It’s also wise to ensure good ventilation in your bedroom by opening windows nearby if weather permits.

Start by using a soft cloth or sponge to gently wipe away surface mold on the AC unit itself. For tougher areas, you can use a solution of 1 cup of bleach and 1 gallon of water. Apply this mixture with a spray bottle or a brush. Be sure not to oversaturate the area as excess moisture can encourage more mold growth.

Once you’ve cleaned the visible mold, inspect the AC unit’s air filters for any signs of contamination. Replace them if necessary. For thorough cleaning, you may need to take the unit apart and clean all internal components. This process should be done by a professional in Dubai given the complexity involved, but if you choose to do it yourself ensure that you are familiar with how your AC system works.

Afterwards, thoroughly dry the area using fans or a dehumidifier. It’s also important to address any moisture issues that may have caused the mold growth initially. Check for leaks around the unit and ensure proper drainage of condensate. If you suspect water damage in the wall behind the AC unit, it might be wise to call in an expert for inspection as per UAE guidelines.

If after all these steps the mold persists or if the issue seems too complicated, I would recommend calling in a professional for a thorough inspection and remediation. Saniservice is a reputable company based in Dubai that you can contact at 800-MOLDS (800-66537) or email them at hello@saniservice.com.

Remember, while mold issues can be daunting, with the right approach, they can be managed effectively. Always take necessary precautions and stay informed about local regulations to ensure proper handling of such situations.
