When the refrigerant is in the evaporator coils, it is in a very cold, liquid state.

As the forced air pushes through the coils, the refrigerant absorbs the heat out of the air, cooling it; the liquid in the coils is transformed into gas as cold air is directed into the home.

The gas flows back to the compressor, which pressurizes it and pushes it through the condenser coils on the outside of the home so the absorbed heat can dissipate.
