- Why are variable-capacity heat pumps more appropriate for cold climates than single-stage heat pumps?
- Single-stage heat pumps cannot provide heating.
- Variable-capacity heat pumps can be oversized for cooling, but modulate down to prevent short-cycling and provide effective cooling and dehumidification.
- Variable-capacity heat pumps provide more heating and cooling than single-stage heat pumps, regardless of climate.
- Variable-capacity heat pumps cannot operate in warm weather.
