You are in roughly the same climate zone as I am. For my shop I have a window style heat pump mounted high in the North wall of my shop. It never produces heat hot enough to cause a fire, but heats, cools, dehumidifies, and filters the dust out of the air in my shop year round. It runs whenever I'm in the shop working or whenever the outside temperatures will go below freezing. I set the temperature to about 50 during the Winter when I won't be working there, and raise it to 65-70 when I'll be there or when finishes are drying. In the Summer i leave it at 75 just about all the time. Since there is never a surface of it hot enough to ignite combustibles, I feel that it is the ideal heating, cooling, and dust filter system that can be had, and it's all in one single cabinet.
Some are installing mini-split systems in their wood shops. If you do this, be sure to add a shop made filter box in the intake and use some high quality furnace filters to keep the inside of the mini-split clean. It will double as a shop air cleaner too.
