Yes, they can (mine does) but I don't see Isaac paying thousands for a Cold Climate Heat Pump. I was talking about him adding a small window unit for less the $1,000 that would provide A/C in the summer and cheaper heating in shoulder season.
Also providing 100% of BTUs at 0 F doesn't mean it makes financial sense to use a heat pump when he has a furnace.
