Was thinking of buying an AC unit after suffering last summer, after looking at this conversation about heat pumps, I read they'd work just as well for cooling and only cost marginally more, and you would see a drop in monthly heating cost with them. Also heard Calgary is too cold for them to be reliable on the coldest days.
Anyone have experience?
Would a duel system where my existing furnace just jumps in for short periods when a heat pump isn't keeping up?
Assuming the grid keeps getting greener (because I think that's a fairly safe assumption ), would running the heat pump for 70% of my heating in the winter offset the extra usage I would create by adding cooling.
poke holes in this thinking.
