The air works well. It is loud and runs a lot. We use this in the upstairs of our farmhouse. Set up took some time (attaching the tubing was a pain). We use ours in a small, side-sliding window. I had to measure and order a new window fitting to make it work. I would find another product to heat the space. The temperature never gets up to the setting and if the air is not dry (enough), the reservoir fills up with water and leaks at the slightest movement.
