Ductless systems are growing in popularity because they have the benefits of separate zones, lower operating costs, easy installation, flexibility, and more. If you have heard about these systems, often known as mini-splits, but aren’t sure how they work, here is a simplified breakdown.

Ductless mini-splits consist of two main parts, an indoor unit and an outdoor unit. The indoor unit is called the handling unit. This unit is usually located high on a wall or suspended from the ceiling. The handling unit sucks air from inside your room and blows it over cold evaporator coils. There is coolant in the coils that evaporates and absorbs energy, which lowers the temperature of the surrounding air. The gas that was created then goes to the outdoor unit.

The outside unit is called a condenser unit and has a compressor that changes the coolant back from a gas into a liquid, thus releasing the heat. A fan then blows the warm air outside away from the unit. The compressed coolant, now a liquid, returns to the indoor unit. The process is then repeated over and over again, lowering the temperature of your home. When you need heat in the winter, the system simply runs in reverse, condensing inside and evaporating outside, which will warm your home.

In a mini-split, all of this happens at the location where the air is needed, so there is much less energy lost from moving the air through the vast network of ducts that is required for regular HVAC systems. This makes ductless much more efficient. Multiple indoor units can be connected to a single outdoor unit to provide heat and AC to the whole house. The handlers are independently controlled to provide maximum comfort where you need it.
