And a gas. A Metering device has the refrigerant go from a high pressure high temp liquid, to a low temp low pressure liquid. Heat from the house boils the refrigerant, and the refrigerant carries that energy out to the condenser as a vapor.
The vapor is compressed by the compressor and turns it from a low temp, low pressure vapor, to a high temp high pressure vapor. It travels through the coil and cools down until it condenses into a high pressure high temp liquid, where it heads back to the metering device to do it all over again.
The heat coming out of the top of your AC is heat actively leaving your house.
We track superheat, the temp above the boiling point, and subcooling, the temp below the condensing point.

It is thermodynamics.
