monster dehumidifier
the dehumidifier is like twice the size i thought it was from the photos i was looking at last month. guess that's what i get for not looking at the specs:

one of the new guys working at the company specializes in airflow stuff, which is resulting in a wacky (but i think ultimately good) setup. instead of installing the dehumidifier near the furnace, where it would be difficult to get truly fresh air from the outside what with the dryer vent and bathroom exhaust vent and all, they decided it would be better to install the unit closer to the center of the house, pull in the fresh air from the completely opposite side of the house from the furnace, and plug directly into the studio. the idea is that the studio will be the first to get the fresh/dehumidified air, but it will then propagate through the rest of the house via the studio returns and we'll have fresh and dehumidified air everywhere.
this whole setup is proving to be a bit more involved than they originally thought, so the rest of the day today is going to be spent knocking out holes and running ductwork and stuff, and then they're coming back tomorrow to do the furnace/dehumidifier installation.
