Can I safely clean AC coils without replacing them?« Back to Previous Page

After the rain last month, I noticed a strange moldy smell coming from the corner near the air conditioner in the living room. It’s concerning because my children play there often, and I’ve been worried about it affecting their health. Is there a safe way to clean the AC coils without having to replace them?

Absolutely, cleaning your AC coils is a sensible and effective way to tackle the moldy smell without having to replace them. In Dubai/UAE, ensuring indoor air quality is crucial due to our climate conditions. Mold growth can indeed pose health risks, especially for children who spend more time indoors.

Firstly, it’s vital to understand that regular coil cleaning should be part of your AC maintenance routine. This task requires some know-how and tools, which I’d recommend you consider getting a professional to do. However, if you're keen on tackling this yourself, here are the steps:

1. Preparation: Ensure the unit is switched off and unplugged from power. Clear the immediate area of any obstructions so you can access the AC system easily.

2. Cleaning Tools: You’ll need a coil cleaner solution (available at local hardware stores), gloves, and a soft-bristled brush or vacuum hose attachment. Avoid using harsh chemicals or abrasive tools that might damage the coils.

3. Coil Access: Locate your AC unit’s filter and remove it to access the evaporator coil. Some units may require you to detach the front panel or cover plate.

4. Cleaning Process: Apply the coil cleaner as per the manufacturer's instructions, typically by spraying directly onto the coil or dipping a cloth in the solution and wiping the coil gently. Use your soft-bristled tool to loosen any debris or mold before cleaning with the solution.

5. Drying: After cleaning, allow the coils to dry completely. In some cases, you might need to use a fan or dehumidifier to speed up this process.

6. Reassembly and Testing: Once everything is dry, reassemble your AC unit and switch it back on to ensure proper functioning.

For more serious cases of mold growth or if you find the task overwhelming, I’d recommend calling in an expert. Here’s a local contact: Call 800-MOLDS (800-66537) for professional inspection and cleaning services. They can also help identify any underlying issues causing moisture buildup.

Remember, maintaining indoor air quality is key to your family's health. Regular coil cleaning combined with proper AC maintenance practices should keep those pesky smells at bay.
