Why is my Mars Air Conditioner not cooling well?
- K
  Katie BartlettAug 3, 2025
  If your Mars Air Conditioner isn't cooling well, there are several potential causes. First, check if the air filter is blocked with dust or animal hair and clean it according to instructions after turning off the unit. Ensure the exhaust hose is correctly connected and not blocked, disconnecting and checking it after turning off the unit. Also, make sure all windows and doors are closed. The temperature setting might be too high, so try decreasing it. The room area might be too large for the unit's capacity, so double-check the cooling area. Finally, remove any heat sources from the room if possible. If none of these steps help, you may need to call a service technician to inspect the unit and top off refrigerant.
