Kelvinator split AC cools but the room never reaches the set temperature.

Steps:

• Clean filters and coils: Wash filters and ensure indoor and outdoor coils are clean.
• Check airflow: Make sure all supply louvers are open and not blocked by furniture or curtains.
• Close room: Close doors and windows to prevent hot air infiltration.
• Verify setpoint: Set the temperature at least 4–6°C below room temperature and allow sufficient time for cooling.
• Sensor location: Ensure the indoor unit is not installed in a hot corner or directly above heat sources, which can mislead the sensor.

Technician tasks: If performance remains poor, have a technician check refrigerant charge and system capacity versus room size.
