Old Window Air Conditioner Not Cooling

Window ac not cooling.

Old window air conditioner not cooling. In a properly working air conditioner a fan will draw air over the evaporator coils where it is cooled and then be re circulated back into the room. A window or room air conditioner that doesn t cool may need to be recharged with refrigerant but the chances are good it simply needs to be cleaned. One of the most common reasons for a window air conditioner to fail to deliver cold air is incorrect mode selection. If the window air conditioner s compressor and fans are running but the air conditioner isn t cooling possible causes include a failed compressor or the lack of refrigerant due to a leak in the sealed system.
