Ductless heating and cooling definitely has its perks—energy efficiency, easy installation and clean air quality, to me a few. This 9,000 BTU mini-split system from Perfect Aire makes even the stuffiest or chilliest room in the house as comfortable as can be without the need for ductwork. The air or heat goes directly to the source without the interference of dust-collecting ducts, so you can easily and efficiently control the room temperature independently from the rest of the house. What a win for older homes with antiquated systems, or smaller spaces that need supplemental comfort.
