Having a ductless heat pump that uses inverter technology will save even more space and be more energy efficient compared to a ducted heat pump. Ductless models are already more energy efficient, and when you add on the option for inverter technology you only boost that efficiency more.

A monobloc heat pump is similar to a boiler in that it is a ‘one block’ system, with all of its components (except the hot water cylinder which is inside the home) inside a single unit that sits outside the home.

Typically, the outdoor unit houses the compressor and condenser, while the indoor unit contains the evaporator coil and an air handling unit that distributes air through the ductwork in your home.

In terms of cooling, heat pumps offer better energy efficiency than air conditioners since they use less electricity. They're more efficient at removing humidity and heat from the air than traditional AC units.
