If it's stopping by itself during cold days in the winter, the outside unit may be performing the "defrosting function", which will briefly stop the indoor unit to heat up the outside unit.
When the outside unit gets too cold, the air conditioner will automatically stop and run the defrost. After around 10 minutes, the outside unit will warm up and the indoor unit will run normally again.
For cold settings the air conditioner may not cool properly when the temperature is too high. Set the function to "冷房(Cold air)" and the temperature to "20ºC" check if there is cold air coming from the vent.
When it's hot the air conditioner may also takes time when changing from hot to cold air.

The filter on the air conditioner must be cleaned periodically so the dust won't clog the drainage system and will also avoid problems with performance and bad smell. For more information regarding the cleaning, click here.
When the air conditioner is on the cool air function, due to the difference in temperature, the moisture in the air will start to condensate and turn into liquid water.
Usually, the water will be gathered by the air conditioner draining system (and expelled through the drain hose). But, if there is any problem with the hose installation, water may start to leak.
After receiving the request, we will contact the tenant to inform and schedule a visit to fix the problem with the leaking. Please, inform us through the [Inquiry Form].
※For this kind of maintenance, we will need the cooperation of the tenant above and the time that will take for the repairs will depend on the tenant availability. We ask for your understanding.
When using a function (cold / hot air) after a while without using it, a bad smell may come from the unit.
Not cleaning the filters periodically may also cause bad smell due to the dust and the dust gathering moisture and mold. Try removing the filters, washing with water and drying under sunlight.
