How Does A Mini Split Heat Pump Work? 

A mini split heat pump uses a small amount of energy to pump heat from one place to another.

A heat pump moves the heat out of your house on a hot day and moves heat into your house on a cold day.

Because a heat pump can be reversed, you do not have to install a different system to heat and cool your home.

Heat pumps are efficient because they just move heat around rather than generate it.

A mini split is a heating and cooling system that does not require duct work.  A mini split has an outdoor compressor and an indoor unit which is called an air handler.  A conduit that goes through an exterior wall connects the compressor with the air handling unit.  Some models allow the use of multiple air handling units that all connect to the same compressor.

You can think of a mini split system as a group of air conditioners that all share the same compressor.  Each air handling unit can be assigned to a different room and controlled by its own thermostat.

A mini split system is easier to install than other heating and cooling system for at least two reasons.

The first reason is that only a small hole needs to be made in an exterior wall for a conduit to connect the internal and external units.

A mini split system comes with a variety of lengths of conduit that provides much flexibility when it comes to installation.  Some systems will allow you to locate the outdoor unit as far as 40 – 50 FT away.

Second, indoor air handlers can be suspended from a ceiling, mounted in a drop ceiling, or hung on a wall.

Floor-standing models are also available.  Air handlers can be remote controlled making them easier to control when they are mounted in a hard to reach location.

Since there are no ducts, mini split systems are great for retrofit add-ons to houses or homes with integrated heating systems such as baseboard heating.   They are also a great choice to overcome the problem of not being able to extend ductwork for a room addition.

Because they have no ducts there is no energy loss associated with the ductwork.  Ductwork losses can account for more than 30% of energy consumption for a conventional system.

The most important advantages of a mini split are its flexibility and compact small size, which is ideal for conditioning individual rooms, and which negates the need to use window mounted air conditioners.

A mini split can independently condition the air in as many as 4 different rooms using only one outdoor unit.   An independent thermostat dictates the temperature required by different rooms that allows you to save money by only conditioning the air in those that are occupied.

A mini split system provides a new way to solve some of the challenges of climate control.  Without incurring high cost remodeling, a mini split system can maintain consistent and predictable indoor temperatures, humidity levels and comfort.
