I'm designing/building out my basement which will include a home office. I'm thinking about using a room air conditioner/heater for it instead of trying to tap off the main furnace. The idea of being able to more precisly control the environment in that room makes sense to me. The room is under 200 sq feet.

I'm curious if anyone has experience with these units and if anyone knows what brands/models are worthy of the investment. The type of device I was considering are the ones that sit in the room, often on wheels and have a single pipe that you need to run outside.
