An air conditioner that has sucked in cigarette smoke or other bad odours may simply be blowing them back out. If the bad smell does not go away, your air conditioner’s air filters, evaporator or condenser coils may need cleaning.
In order to clean the filters, consult your user manual, as each model may have different instructions. If you’re having trouble finding your manual, download it here using your product’s model number. To get the evaporator and condenser coils cleaned, please contact an authorised service agent.
