Actually, a whole house AC running on a normal dedicated 2 phase 220V line
has a LOT more air drying capacity than a portable, "regular", 120V
dehumidifier.

The house AC is around 4-10x more powerful and typically more efficient than a
portable unit. It also dumps the collected water to drain, while the
portable would have to be emptied or setup with a hose.

AC and dehumidifiers freeze up or lose efficiency when the house gets too cold
so the owner may have to alternate some heat cycles with the furnace to keep
the temperature above 65F in order for the AC to function well. That's why
they rate AC at a really high temperature such as testing at 85F in 85%
humidity. IF they tested those at 60F they'd barely work. .
