Why is my Arbaco ACW600C Air Conditioner not cooling properly?

If your Arbaco Air Conditioner isn't performing well, several factors could be at play. Ensure the unit isn't in direct sunlight; if it is, close the curtains or shades. Also, close any open doors or windows, especially if there are many people or a heat source in the room. This unit isn't designed for server rooms or rooms generating constant heat. Check if the filter is dirty and clean it if necessary. Make sure that neither the air inlet nor the air outlet is blocked by powering off the unit, unplugging it, and removing any obstructions. Finally, ensure the room temperature isn't lower than the temperature you've selected; try setting it to the lowest possible setting of 60°F.
