If you have a basic understanding of how your air conditioner in Washington, D.C. works, then you understand that the refrigerant in your system plays a vital role in the cooling process. Refrigerant is a heat transfer fluid that is evaporated in the indoor coil of your air conditioner. As the refrigerant evaporates, it draws heat out of the air surrounding and passing over the evaporator coil. The heat is released outside as the refrigerant is condensed, and the cycle continues until the desired temperature is met.
What you may not realize, though, is that “refrigerant” is an umbrella term covering many different heat transfer chemical blends. R-22 is one of the most common refrigerants used in air conditioning systems today. It is also being entirely phased out of use and production in accordance with the Clean Air Act of 2010. 2020 will mark the completion of the R-22 phaseout.
