Not cooling enough
What you see
The air from the indoor unit is barely cool, or the room never reaches the set temperature.
Likely causes
Dirty filters, the wrong mode or setting, an outdoor unit with no space around it, then low refrigerant from a leak, a fan fault or the compressor.
Safe to try
Clean the filters, set Cool mode, close doors and windows, and clear the area around the outdoor unit.
Technician
A qualified technician checks the pressures, looks for leaks and tests the fans and compressor before adding any refrigerant.
