Anyone in a cold climate have any experience with these units? Cold climate meaning upstate NY area, or equivalent. I realize that in the winter we're not going to get much if any heat out of the unit, but from March - May, and Sept - Dec., I'm thinking that an ASHP could be a good supplement to our existing propane furnace. We currently do have central air, a forced hot air LP furnace, etc., so this would essentially be a drop in unit.
