Ductless AC and heating systems use a pair of indoor and outdoor units to warm or cool specific areas of your home. These energy-efficient units are easy to install and offer a flexible, low-cost solution for zoned heating and cooling. Best of all, there’s no ductwork needed.
Single-Zone Ductless
Single-Zone ductless systems control the temperature in one area of your home by connecting one outdoor unit to one indoor unit.
Multi-Zone Ductless
Multi-Zone ductless systems control the temperature in multiple rooms or your entire home by connecting one outdoor unit to multiple indoor units.
Single-Zone Ductless Products
Ductless systems allow for flexibility. A single-zone (also called a mini-split) ductless system allows you to control the temperature of one room by connecting an outdoor unit to an indoor unit, with no ductwork needed. An outdoor mini-split unit is placed outside your home and is connected to an indoor mini-split unit by small cables and a refrigerant line through a hole in the wall.
