Preventative Measures To Keep Mold At Bay

Regular maintenance and cleaning are key to preventing mold in your AC unit. Make sure to clean or replace air filters monthly. This keeps the air flowing smoothly. Clean all AC parts, like the drain pan and coils, every start of the season. An HVAC professional can perform a thorough cleaning.

Keeping indoor humidity levels low helps stop mold growth. A dehumidifier can reduce moisture in the air. Use it especially during hot, humid months. Ensure your AC unit is the right size for your room. A too-big unit can lead to short cycling, which doesn’t control humidity well.

Improving air circulation in your home is essential. Use ceiling fans to help move air around. Also, consider installing UV lights near the AC coils. UV-C light kills mold and germ in the air. This technology is used in hospitals for clean air.

Step-by-step Guide To Removing Mold From Ac Units

Safety should be your top priority before tackling mold in an AC unit. Wear gloves, goggles, and a mask to protect from mold spores. Make sure the AC unit is turned off and unplugged to prevent electric shocks.

Begin by cleaning the easy-to-reach parts of your AC. Use a soft brush and a mixture of water and mild detergent. Gently scrub the surfaces, such as the grills and drain pans, to remove visible mold. Avoid harsh chemicals that can damage the AC components.

For a thorough clean, the air ducts and internal parts require attention. A vacuum with a HEPA filter is perfect for sucking up mold spores. After vacuuming, use a damp cloth with an approved cleaner to wipe surfaces. This step ensures your AC runs efficiently and stays mold-free.
