    I'm thinking the bigger issue is a mismatch of equipment. With straight air conditioning you can get by with a mismatch, but a heat pump (which I'm guessing you have) is a lot more fussy.

    Yeah, what chrisevansac said.

    Yes, that is correct. It sucks air in from the duct that it's mounted to, humidifies it, and then blows it back into that same duct.

    When it gets too dry the horse hair curls up or something and makes the humidifier turn on.
