Possible Causes

Room too large or too humid for capacity, Doors/windows open, Dirty coils reducing efficiency, Low refrigerant charge or weak compressor

Safety: Unplug before cleaning.

Steps:

1. Check room conditions: Close doors and windows. Reduce other moisture sources if possible.
2. Clean filter and coils: Improve heat exchange by cleaning dust from coils.
3. Verify capacity: Ensure the Ariston unit’s rated capacity (L/day) is appropriate for the room size and humidity load.
4. If performance remains poor: A technician should check system pressures and compressor performance for possible refrigerant or compressor issues.
