    Why is my COMFORT-AIRE PSH-141A Air Conditioner not cool enough?
    • S
      Shannon FergusonAug 3, 2025
      If your COMFORT-AIRE Air Conditioner isn't cooling enough, several factors could be at play. First, ensure all windows and doors are closed to keep the cool air from escaping and remove any heat sources from the room. Check that the exhaust air duct is properly connected and not blocked, allowing it to function as intended. Also, make sure that the temperature setting isn't too high; try decreasing it. Lastly, a dusty air filter can restrict airflow, so clean the air filter. If the unit has overheated, allow it to cool down before switching it on again.

      Anna ChavezAug 20, 2025
      The COMFORT-AIRE Air Conditioner might be shutting off in heating mode due to the automatic overheat protection function. When the temperature at the air outlet exceeds 158°F/70°C, the device will automatically stop to prevent overheating.
