Humidity: The Real Enemy
The main problem during the monsoon isn't just the temperature; it's the high humidity. When the air is saturated with moisture, it feels heavy and sticky. This moisture prevents your sweat from evaporating effectively, which is your body's natural cooling
mechanism. As a result, a room at 27°C can feel much more uncomfortable than a dry room at 30°C. Standard air conditioning cools the air, but to truly feel comfortable during the monsoon, your primary goal should be to remove this excess moisture. High humidity also creates the perfect breeding ground for mould and mildew within your AC unit and in your home, which can lead to musty smells and health concerns.
Your Secret Weapon: Dry Mode
Most modern air conditioners come with a feature often marked by a water drop symbol: the 'Dry Mode'. This is your most valuable tool during the rainy season. Unlike the regular 'Cool Mode,' which focuses on lowering the temperature, Dry Mode's main job is to function as a dehumidifier. It operates by running the compressor and fan at a lower speed, allowing the air to spend more time passing over the cold evaporator coils. This process maximises moisture condensation, which is then drained away. The result is drier, more comfortable air without making the room excessively cold. This not only improves comfort but is also highly energy-efficient, as the compressor isn't working continuously.
Find the Temperature Sweet Spot
Cranking the AC down to 18°C is a common mistake during the monsoon. While it might seem like the fastest way to get comfortable, it's counterproductive. An extremely low temperature can over-cool the room, making it feel cold and damp, and can even cause condensation to form on your walls and furniture. For the Indian monsoon, the ideal temperature setting is generally between 24°C and 26°C. This range is cool enough to be comfortable while allowing the AC to run efficiently and effectively remove humidity. If the room still feels sticky, resist the urge to lower the temperature further and use Dry Mode instead.
Fan Speed and Swing Settings
When using Dry Mode, the AC will typically run the fan at a low speed automatically to maximise moisture removal. If you're using Cool Mode, setting the fan to 'Auto' is a good choice, as it allows the unit to adjust the speed based on the room's conditions. Avoid using only the 'Fan Mode' without any cooling, as this will just circulate the humid air, potentially making the room feel even muggier. To ensure the conditioned, dry air is distributed evenly, turn on the 'Swing' mode. This keeps the air vents moving, preventing pockets of warm or damp air from lingering in corners of the room.
Essential Monsoon Maintenance
The combination of dust and high humidity during the monsoon can quickly lead to problems. The most critical maintenance task is to clean your AC's filters regularly—at least every two weeks. A dirty filter restricts airflow, forcing the unit to work harder and reducing its ability to dehumidify. Clogged filters also trap moisture, creating an ideal environment for mould and bacteria to grow. Additionally, ensure the outdoor unit is clear of any debris like leaves or twigs that might be blown around during storms, as this can block airflow and cause the unit to overheat. Finally, check that the condensate drain pipe is clear and not blocked, which can cause water to leak back into your room—a common monsoon complaint.
