Understanding Refrigerant and Its Role 24 Hour Ac Company Residential Ac Repair Air Conditioning Repair Contractor Heating Ac Service Near Me Air Conditioning And Heating Services

Before we dive into the refill process, let’s understand what refrigerant is and its function. Refrigerant is a substance that absorbs and releases heat, enabling the AC system to cool the air. It circulates through the system in a closed loop, undergoing a phase change from liquid to gas and back again. This process is what removes heat from the air inside the vehicle or building and releases it outside.
