It is currently defrosting.
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.
If the steps above are not the issue, it may be another problem or a malfunction.

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 the details of the air conditioner and the problem through the [Inquiry Form].
