This is a common misconception—appliances that cool (air conditioners, refrigerators, etc.) do not “use up” Freon. They actually cycle the Freon through its system—using the same amount of Freon over and over again through a sealed system. It is important to note that there are other causes for poor cooling that could have nothing to do with Freon levels. A service visit and appliance inspection from one of our highly trained and experienced appliance repair technicians will identify what is wrong and the best course of action.
