Ductless mini split heating and cooling systems

Have you heard the term "Ductless heat pump" or "mini split" before? Maybe you have been wondering what is that silly looking thing on the wall of the homes I am seeing on House Hunters international on HGTV, well wonder no more.
A Ductless mini split heat pump system is a more modern style of heating and cooling system that has been used around the world for many years but has only become popular in the US in the past few years(although Sky Heating has been installing these for over 10 years now). In the rest of the world over 70% of heating and cooling systems are a form of a ductless mini split, we are one of the only parts of the world that uses ductwork to heat and cool a home. Ductwork has the potential to leak energy, to leak air and to pull in air from unconditioned spaces like a garage, attic or crawl space. Nobody wants to be heating their crawl space while breathing in air from their attic with ductwork. We also have cars with up to 4 heating zones yet most homes only have 1 heating zone? Its amazing that a car that is maybe 120 sq feet and used an hour a day has more comfort than a house that is 10X the cost, 10-40X the size and used up to 24 hours a day. With a ductless mini split a wall head goes into each room of the home or the main areas of the home depending on cost.
Each of these wall heads can independently heat or cool, so the living room can be set to 72 degrees when company is over, the guest bedroom can be set to save energy at 60 degrees and the master can be set for 68 degrees for the ideal sleeping conditions. With a ducted system the whole house is whatever temperature you set the thermostat. This is also saves energy because you only heat or cool the areas that you need to rather than wasting energy and heating the entire home when only when room is being used at a time. Ductless mini splits are also up to double the efficiency of standard heating systems like gas furnaces or basic heat pumps. Ductless mini splits both heat and cool so you get both benefits out of one unit and they are incredibly quiet, usually they produce less noise than a refrigerator!
Sky Heating and Air Conditioning even uses a Daikin Ductless mini split to heat and cool our office.
