Refrigerant Issues: Therefore, Air conditioners use Freon as a refrigerant to soak up the warmth and humidity from the space air. Because it does, it turns from a high-pressure gas to a low-pressure liquid then reverts once it cools again. As air conditioners age, the metal can erode, resulting in a Freon leak, therefore the unit won’t cool the air effectively. Uncontrolled leakage of Freon also can cause refrigerant poisoning if not taken care of promptly. Hence, they should be checked by the experienced technicians and make proper gas filling in the Air-conditioner. Samsung Service Center in Tarnaka Hyderabad
