The Importance of AC Refrigerant in Your Air Conditioner
Refrigerant, also known as coolant or Freon, plays a crucial role in the functionality of your air conditioner. It is responsible for absorbing heat from the indoor air, expelling it outdoors, and ultimately delivering cool air to your space. Whether you have a ducted or ductless air conditioner, refrigerant is used to cool your house effectively.
Understanding How AC Refrigerant Works
AC refrigerant undergoes a state change from fluid to gas and back again as it flows through the various components of your air conditioner. This process allows it to extract heat from the indoor air and release it outside, resulting in the production of cool air. In the case of a reversible AC system, refrigerant can also provide heating functions.
Identifying and Dealing with Refrigerant Leaks
Occasionally, refrigerant leaks can occur, causing a significant decrease in your AC’s cooling performance. If you notice that your air conditioner is not cooling as it should, experiencing higher energy bills, or observing water leakage, it is essential to check for possible refrigerant leaks.
Here are some signs that indicate a potential AC refrigerant leak:
