2 feet from the house is a lot. I'm on my second home with heat pumps, and both, as well as every other one I've seen is less than a foot from house. First home, I built a roof like shown above. It worked well. Given there isn't much you can do about the distance away from house, I'd leave maybe a foot clearance on the sides of the unit(s) and then put a wall to the house attached to the roof you are building. That will keep the majority of snow from blowing behind the unit, and still allow more than enough airflow.
