A ductless split system is a wise choice if you live in a home that does not have sufficient space for large ductwork inside the walls. Some older homes were not built with central heating and cooling in mind, so a ductless system can fit into one of these houses without much disruption. If you are building a new home, going ductless will give you more space and more freedom to design the interior you want.
Ductless mini splits help with indoor air quality. A system that uses ducts will have dust, dirt, and other debris begin to gather inside the ventilation system, and the air flow will pick it up and blow it into the house. On the other hand, a ductless heating system blows out air that is almost contamination–free.
If you are interested in reducing energy waste in your home, a ductless mini split system is also an excellent idea: without long stretches of ductwork, these heaters don’t lose energy through duct walls. You will have much more efficient heating.
Another thing to keep in mind: because ductless heating systems are heat pump, they also supply cooling whenever you need it as well!
