Preventing Mold In AC Unit and in Ducts

When choosing an AC system to prevent mold, humidity control is the key factor. The best units combine strong dehumidification, high-quality filtration, and UV technology to stop mold growth before it starts.

Key Features for Mold Prevention

1. High-Efficiency Dehumidification
   • Choose an AC unit with a dehumidification feature built in to efficiently remove moisture from the air.
2. High-MERV Air Filters
   • Filters with a MERV 15+ rating trap mold spores, dust, and allergens before they circulate in your home.
3. UV Germicidal Lamp
   • A UV light inside the AC unit kills mold and bacteria on the evaporator coil, preventing buildup.
4. Proper System Sizing
   • An oversized AC cools too quickly without running long enough to dehumidify properly, increasing mold risks.
5. Proper Air Distribution
   • Undersized Duct Work is very common and it leads to restriction of proper air flow thus reduces the ac units ability to remove humidity.

Best AC System Types for Mold Control

• Variable-Speed ACs – Adjust cooling capacity for precise humidity control.
• Duct Design and Layout – Proper air flow is key to circulating air effectively in order to extract humidity from the air.
• Whole-House Dehumidifiers – Work alongside your AC for extra moisture control.

Important Considerations

• Regular Maintenance – Change filters, clean drain pans, adequate water drainage, and schedule professional tune-ups.
• Address Moisture Sources – Building envelope leakage, Fix leaks, improve ventilation, and manage indoor humidity levels.
