If your Bosch air conditioner releases an unusual odour when turned on, it could be a sign of mould or mildew growth caused by moisture collection within the unit.
To address this, turn off and disconnect the unit for safety reasons. Remove the air filters and clean them with mild soap and water, then let them dry fully before reinstalling.
Next, check the drain pan and condensate lines for obstructions or standing water, which can harbour mould. Clean them carefully to guarantee adequate drainage.
Regular maintenance, including professional servicing, is required to avoid future odour problems and maintain maximum air quality.
