Lots of good advice here, talk with at least 3 installers, even if you're qualified to do it yourself. That will give you other professionals ideas to work with. Biggest thing I didn't see mentioned here is to calculate your recovery time, ie. when you open the door at 30 below, how fast do you want the space to get back to temperature. That will help dictate the size of unit you install. And it makes a difference how much insulation you put in, I have R50 in my ceiling and R20 in my walls and R16 doors in my garage (30 by 32 by 9) and a 6500watt electric keeps it cozy at -50. YES -50!
