KEEP MOULD OUT OF YOUR A/C WITH THESE SIMPLE STEPS
Indoor air quality is crucial for a healthy home, and your air conditioning system plays a big role in that. While A/C units keep us cool and comfortable, they can also become a hidden source of mould if not properly maintained. Mould growth inside your air conditioner can release spores that circulate throughout your home, potentially causing allergic reactions, respiratory issues, and other health problems.
Why Does Mould Grow in Air Conditioners?
Mould thrives in damp, dark environments—and your air conditioner can be the perfect breeding ground. Moisture accumulates inside your unit, especially in parts like filters, coils, and drain pans. If the system isn’t cleaned regularly or runs infrequently, mould can develop and spread spores into the air you breathe.
5 Easy Ways to Prevent Mould in Your A/C
1. Run Your Unit Regularly
Even when you’re not actively cooling your home, running your air conditioner periodically helps reduce moisture buildup inside the system. This is especially important during cooler months when your unit might sit idle. Keeping air circulating helps prevent damp conditions that mould loves.
2. Use the “Dry” or “Dehumidify” Setting When It’s Humid
Many modern A/C units have a “dry” or “dehumidify” mode designed to remove excess moisture from the air without cooling it too much. Using this setting helps keep both your home and your air conditioner dry, reducing the risk of mould growth.
3. Clean or Replace Your Filters Every 1–2 Months
Filters trap dust, dirt, and moisture, creating a prime spot for mould if left dirty. Regularly cleaning or replacing filters prevents buildup and keeps the air flowing cleanly through your system. Rinse reusable filters with water and allow them to dry completely before reinstalling.
4. Keep the Area Around Your Indoor and Outdoor Units Clear
Good airflow around your A/C unit is critical. Indoors, avoid blocking vents or returns with furniture or curtains. Outdoors, remove leaves, branches, and other debris around the unit to prevent airflow restrictions, which can cause moisture buildup and mould growth.
5. Book Regular Professional Servicing
Even if your system seems to be working fine, scheduling professional maintenance helps catch hidden mould and other issues early. Technicians can clean parts of your system that are difficult to access and ensure everything is running efficiently and safely.
