The rainy season in Singapore brings cooler weather. However, it can also cause aircon problems if you do not take care of your unit. High humidity, sudden temperature drops, and long wet periods can affect your aircon’s performance. So, here is a simple guide to help you keep your aircon clean, safe, and efficient during rainy days.
1. Check and Clean Your Air Filters
During the rainy season, the air becomes more humid. As a result, dust and moisture can build up on your filters faster.
What to do:
Remove your air filters.
Wash them with mild soap and water.
Let them dry completely before placing them back.
Why it helps:
Clean filters improve airflow and prevent your aircon from overworking. In addition, they help your unit cool faster.
2. Keep the Outdoor Unit Clear
Heavy rain and wind can blow leaves, dirt, and small debris into your outdoor condenser. Because of this, the unit may struggle to release heat properly.
What to do:
Check the condenser area often.
Remove anything blocking the unit.
Why it helps:
Good ventilation prevents overheating. Furthermore, it helps your aircon last longer.
3. Watch for Signs of Leaking
The high humidity during rainy days means your drainage system may collect more water. Eventually, this can lead to leaks inside your home.
What to look for:
Dripping water
Damp walls
Water trails near the fan coil unit
What to do:
If you notice leaks, call an aircon technician right away. Otherwise, the leak may worsen and damage your walls or flooring.
4. Use Dry Mode on Wet Days
When humidity is high, your aircon works harder. Fortunately, most units include Dry Mode.
Why it helps:
Dry Mode removes extra moisture without using too much electricity. Therefore, it is perfect for rainy, humid days in Singapore.
5. Do Not Cover Your Outdoor Unit
Many homeowners cover the condenser when it rains. However, this can trap moisture and cause rust or electrical problems.
Better option:
Leave your outdoor unit uncovered so it can release heat properly. On the other hand, make sure there are no large objects blocking it.
6. Get Regular Aircon Servicing
Even with proper care, your aircon still needs professional servicing—especially during the rainy season. After all, a trained technician can spot issues before they turn into bigger problems.
A technician can check:
Drain pipes
Refrigerant levels
Coil cleanliness
Electrical connections
Fan and blower condition
Overall, regular servicing keeps your aircon safe, clean, and long-lasting.
