Monsoon Season & Your Aircond – What You Should Know
Introduction
When the monsoon season hits Malaysia, most people expect cooler days, cloudy skies, and frequent rain showers. While that’s true, many homeowners are surprised when their aircond starts behaving differently—cooling slower, creating more moisture, dripping water, or even consuming more electricity than usual.
Why does this happen if the weather is cooler? The answer lies in the unique combination of humidity, air pressure, wind direction, and moisture levels during the monsoon. These changes directly affect how your aircond works, making the rainy season a surprisingly challenging period for cooling systems.
In this guide, you’ll learn exactly what happens to your aircond during Malaysia’s monsoon season, the problems to watch out for, and what you can do to keep your unit running smoothly. And if you need professional help, you can always count on JB Cool Care at jbcoolcare.com.
Why Does Your Aircond Feel Weaker During Monsoon Season?
Even though monsoon weather feels cooler outdoors, your aircond often feels weaker indoors. The main reason? Extreme humidity.
Humidity during monsoon season can reach over 90%, and when the air is packed with moisture, your aircond has to work double to remove it before cooling your home.
So while the outside temperature drops, the moisture level skyrockets—and this moisture is what makes your aircond feel weak or slow.
Humidity: The Hidden Factor That Affects Cooling
When humidity rises, the air inside your home becomes heavier and more saturated with water vapor. Your aircond doesn’t just lower temperature—it also acts like a giant dehumidifier.
During monsoon season, your aircond must:
- Extract more water from the air
- Condense moisture faster
- Drain more liquid
- Run longer cycles
That’s why you may notice your indoor unit dripping more water or making more noise. The unit is doing extra work behind the scenes.
Rainy Season Creates More Indoor Moisture Than You Realize
Most Malaysians don’t realize how much moisture enters their homes during monsoon season. A few common ways include:
- Wet clothes drying indoors
- Damp floors from rainwater
- Moisture entering through gaps in windows
- Walls absorbing outdoor humidity
- Reduced sunlight preventing natural evaporation
When your room becomes damp, your aircond has to remove all that moisture before cooling the air, leading to slower cooling performance.
Low Atmospheric Pressure Makes Cooling Less Efficient
Monsoon weather brings low-pressure systems. Low pressure affects the refrigerant inside your aircond, making cooling slightly less efficient.
This means:
- Heat exchange becomes slower
- The compressor needs to work harder
- Cooling takes more time
- The temperature feels uneven
These pressure changes may be invisible to you, but your aircond definitely feels the impact.
Common Aircond Problems During Monsoon Season
The monsoon season doesn’t just affect cooling—it also increases the chances of certain aircond issues. Some of the most common problems include:
- Slow cooling
- Water dripping or leaking
- Mold growth inside the aircond
- Bad odors
- Noisy indoor or outdoor units
- Ice forming on the evaporator coil
- Higher electricity bills despite cooler weather
If you notice any of these symptoms, it’s a sign that your aircond needs professional attention.
Your Filter Gets Dirty Faster During Monsoon
Humidity binds dust, dirt, and fine particles together, making them stick to your aircond filter more easily. A dirty filter restricts airflow and forces your aircond to work harder.
Signs your filter is clogged:
- Weak airflow
- Uneven cooling
- Unpleasant smell
- Aircond takes longer to start cooling
- Increased energy consumption
Cleaning your filter every 2–4 weeks during monsoon is essential.
Dry Mode: Your Secret Weapon During Monsoon Season
Most Malaysians use “Cool Mode” all year—but during monsoon season, Dry Mode is far more effective.
Dry Mode helps by:
- Removing moisture quickly
- Reducing the sticky feeling indoors
- Preventing mold growth
- Making the room comfortable without overcooling
- Reducing electricity usage
If your room feels cold but damp, switch to Dry Mode for 20–40 minutes before returning to Cool Mode.
Your Outdoor Unit Works Differently During Heavy Rain
The outdoor unit (condenser) must release heat to cool your home. But during monsoon season, heavy rain and humid air make this harder.
Rain affects the outdoor unit by:
- Reducing heat dissipation
- Cooling the coil unevenly
- Affecting airflow if rain direction is strong
- Increasing moisture buildup
If the unit is installed in an enclosed balcony or tight space, this issue becomes even worse.
Water Leaking Issues Increase During Monsoon
High humidity creates more condensation on the evaporator coil. When combined with dust or clogged drainage, water leakage becomes very common.
Why leakage happens:
- Blocked drain pipe
- Full drain tray
- Mold growth
- Poor airflow
- Low refrigerant gas
If your aircond drips or leaks more during monsoon, it’s not a coincidence—it’s weather-related stress. A quick service from JB Cool Care can fix this.
Mold Growth Accelerates During Rainy Season
The monsoon season creates the perfect environment for mold:
- High humidity
- Damp rooms
- Reduced sunlight
- Moisture inside aircond components
Mold leads to:
- Bad smell
- Health issues
- Allergies
- Poor cooling
- Dirty coils
- Clogged filters
A chemical cleaning service helps eliminate mold and restore clean airflow.
Tips to Improve Your Aircond Efficiency During Monsoon Season
Here’s how to help your aircond survive the rainy season with ease:
- Clean filters regularly
- Use Dry Mode before Cool Mode
- Close all windows and doors
- Avoid drying clothes indoors
- Keep rooms well-ventilated when not cooling
- Check drainage pipes
- Ensure outdoor unit has good airflow
- Schedule regular servicing
These simple habits can improve cooling and reduce energy consumption.
When You Should Get Professional Help
If your aircond still struggles despite regular maintenance, it may indicate deeper issues:
- Low refrigerant gas
- Dirty evaporator or condenser coil
- Blocked drain pipe
- Faulty fan motor
- Weak compressor
- Mold inside the unit
- Sensor or PCB problems
A professional inspection can detect and fix these issues before they worsen. For reliable, fast service in Malaysia, visit jbcoolcare.com.

FAQs
1. Why does my aircond cool slowly during monsoon season?
High humidity slows down the cooling process because your aircond must remove moisture first.
2. What mode should I use during rainy weather?
Dry Mode is ideal for removing humidity before switching back to Cool Mode.
3. Why is my aircond leaking more during the rainy season?
Excess moisture leads to more condensation, which often causes drainage problems.
4. Does rain affect the outdoor unit?
Rain doesn’t damage the unit, but humidity makes heat release less efficient.
5. Who can help service my aircond during monsoon season?
