Here's How Ductless Works
Ductless splits, also called "Mini-Splits" pump cooled or heated refrigerant directly to the wall or ceiling-mounted air-handling unit.
Here's how the system works in a single room application:
- The indoor unit uses refrigerant to cool or heat air and quietly pushes the chilled air it where you need it in your living space.
- Refrigerant and electrical lines connect the outdoor unit to the indoor unit through a 3" opening in the exterior wall.
- The outdoor unit's state-of-the-art heat pump cools or warms refrigerant and sends it back inside to the air handler, which continuously monitors the room for changes in temperature and sends conditioned air to the areas of the room that need it.
Or if you're using ductless as a whole home solution, up to 9 indoor units can be installed using the same outdoor unit.
The Components of a Ductless System
Also referred to as an evaporator or air handler, this can either be a high wall, low wall (above) or ceiling unit. There's even a ducted option.
The line sets consists of a power cable, condensate drain, refrigerant and suction tubing all connected to the indoor unit through a 3" hole.
Each outdoor unit, or condenser, can interface with up to 9 indoor air handler units and is designed to tolerate the weather and elements.
Zoning Options That Help Save You Money
Ductless air conditioners and heat pumps can be installed so that one indoor unit corresponds to one outdoor compressor. The compressor carries refrigerant and power to the interior unit via a small pipe, running through a small opening, installed with very little impact to your home.
One outdoor compressor can power up to nine indoor units, each separately controlled by a wireless remote, offering you flexible options for configuring your comfort solutions. You can even choose to add units to your compressor in the future after you’ve installed just two indoor units (depending on the maximum number of connectable units), allowing for more streamlined expansion or renovation of your home as time and budget allow.
