Do heat pumps work well in Denver’s climate, without a backup furnace?

For a new home in climate zones 4 or 5 (all areas of Colorado except for the mountain areas), a cold-climate heat pump system will work very well without a backup furnace. However, for an existing home in these areas with a gas furnace, it will probably be more cost-effective to keep the existing furnace as a backup.
