Re:Do heat pumps work in cold climates?

This and other comments here are very useful for me. Been thinking of getting a heat pump for the areas of the house that aren't reached by the pellet stove. It regularly gets to -20C here but not usually for very long so I think we'd be fine. Also we could use it for cooling for the few weeks a year when it's 30C+.

Here we ofter have summer temps around +30C and winter -20C, in both I am very happy to have our heat pump. Our unit is operational down to -25C but for the handful of weeks where it does get that low we do run the gas furnace a little just to top up.
We installed three mini splits in total for a ~2k sq ft 1800s draughty home. Before we had them our central air gas furnace, which is ~20 years old, would burn through upwards of $600 a month of gas in winter. With heat pumps we pay $180 a month equalized and we run heat or cool all year except for maybe a month in spring and fall where it's perfect 22c outside.
Without this magical tech we'd be broke or cold in the winter and uncomfortable all summer.
Were you able to install it with your existing furnace or did you have to replace the furnace?
They mention mini splits, which could very well be installed in addition to or even in lieu of a traditional central HVAC.
