Refrigerant is a specially formulated mixture that's sole purpose for transforming hot air into cold air. Refrigerant gas, previously known as “freon” (due to threats about the use of the name), is used for most home heating, ventilating, and air conditioning (HVAC) units in America. A special switch is designed to sense when there isn’t enough pressure (or when pressure is too high) and disengage the AC compressor clutch, which operates the compressor to pressurize the system. In conclusion, it's important to get a handle on the heat-transfer and air-conditioning cycle to truly understand freon and freon levels. All these should be sealed with duct sealer mastic.
