The Pros and Cons of Ductless Mini-Split Heat Pumps
Increasingly, ductless heating and cooling systems are gaining popularity in the U.S. and around the world. They offer an energy-efficient and convenient way to condition part or all of a home, with much less energy waste than occurs in central forced-air HVAC systems.
While a ductless mini-split heat pump is ideal for heating and cooling a home addition, it also can be a whole-house solution.
When it comes to HVAC technology, ductless systems work similarly to common air-source heat pumps. They come with an outdoor compressor/condenser unit that’s connected to an indoor air handler or multiple indoor air-handling units with a conduit containing refrigerant and electrical lines. For heating, the mini-split transfers heat energy from outside to inside for heating, and vice versa for cooling, using refrigerant running through lines and coils.
Similarities with standard forced-air heat pumps and A/Cs end when it comes to air distribution. The ductless mini-split distributes heated or cooled air directly into the room where the air-handling unit is located, rather than through a network of ducts. For conditioning more than one room, homeowners have the option of installing multiple air handling units.
A ductless system experiences none of the energy waste that occurs when ducts leak or heat transfers through thin duct walls in forced-air systems. Mini-splits also offer independent, zoned heating and cooling. If you don’t want to condition a particular room, you can turn off the air handler serving that area. Ductless mini-splits offer a variety of installation options that can work with your indoor decor. Finally, they come with high efficiency ratings for both cooling and heating.
A ductless mini-split system may be more expensive than a standard heat pump system and may not be the best option for a home with ductwork installed. Otherwise, any minuses that ductless systems experience are common in regular heat pumps, such as struggling to provide comfortable heat in very cold temperatures.
