      Patrick MoodyAug 14, 2025
      If the heating mode on your Rotenso Air Conditioner isn't providing a comfortable temperature, it could be due to a drop in the outside air temperature, which reduces the amount of heat the unit can transport. It's recommended to use an additional heating device in such cases.
