Dirt build-up in the air filters, evaporator and condenser coils may lead to a drop in your air conditioner’s airflow. These filters need to be cleaned every 3 months or whenever there’s a drop in performance. If the air filters are dirty or clogged, the cool air produced by your air conditioner won’t circulate properly throughout the room. 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. You can also contact an authorized service agent to get your evaporator and condenser coils cleaned.
