  Brianna SmithJul 31, 2025
  If your Trane Air Conditioner isn't cooling well, consider these potential causes: the air filters might be dirty, something could be blocking the air inlet or outlet of the indoor and outdoor units, the temperature setting may not be appropriate, windows and doors might be open, or the air flow rate and direction might not be set correctly. To resolve this, ensure the air filters are clean, remove any obstructions, check the temperature setting, make sure all windows and doors are closed, and adjust the air flow rate and direction appropriately.
