You already did include it. We were talking about a dehumidifier that
uses say $30 worth of electricity a month. That $30 includes the heat
that's generated by the compressor motor. Essentially all that $30 winds
up as heat in the room.

I'm sure you know but it may not be obvious to all that the $30 for operation of the equipment does not include the heat generated by phase change of the water being condensed.

Air conditioners use a given amount of electricity to produce a given amount of work.

But they move about 5 times as much heat as the work that is input. Some of that heat is latent heat.
