Heat pumps sold so fast in Maine, the state just upped its target

This is a most excellent place for technology news and articles.
Not at all. A mini split is a kind of heat pump, but refers to a specific kind of installation.
Most of these are "air source" heat pumps, but there are also ground source or geothermal pumps that exchange heat using a loop of liquid buried in the ground.
We're installing a "whole house" air source heat pump to replace our 40yo inefficient gas furnaces and add cooling. This will utilize our existing duct work.
If you don't have duct work (and can't without razing your house to the ground and rebuilding) a mini-split is the only option right?
