How Ductless Mini Split Systems Work
Ductless mini splits are designed to efficiently transfer heat between the indoor and outdoor units without the need for bulky ductwork. They use a slim conduit, typically routed through a three-inch wall or ceiling opening, to connect the outdoor compressor to the indoor air handlers. This conduit contains refrigerant lines, power cables, and a drain line. Below are a few more key insights about mini split systems:
Key Components for Ductless Mini Split HVAC Systems
- Outdoor Unit: Located outside, this unit manages the heating and cooling process by housing the compressor, condenser coil, and fan.
- Indoor Unit(s): Wall, ceiling, or floor-mounted units equipped with an evaporator coil and fan to condition the air in individual rooms or zones.
- Refrigerant Lines: Responsible for transferring refrigerant, these lines allow heat to be absorbed from the indoor air and released outdoors or the other way around.
- Controls: With a remote or thermostat, homeowners can control temperature, fan speed, and additional settings for a more customized experience.

Cooling Process
With a mini split system, heat is swiftly removed from your space, keeping the room cool and comfortable all day long.
- Heat Absorption: Warm air from the room is pulled into the indoor unit, where it flows over the evaporator coil, allowing the refrigerant to absorb the heat.
- Heat Transfer: After warming up, the refrigerant is transferred through the refrigerant lines to the outdoor unit.
- Heat Release: In the outdoor unit, the heat is released into the outside air. A fan aids this process.
- Refrigerant Recycling: After cooling, the refrigerant cycles back to the indoor unit, ready to absorb additional heat.
Heating Process
Mini split systems efficiently convert outdoor air into warmth, keeping your indoor space comfortable regardless of the external temperature.
- Heat Absorption: The outdoor unit extracts heat from the outside air, even in cold temperatures, and transfers it to the refrigerant.
- Heat Transfer: The refrigerant’s temperature is raised by the compressor, and it travels to the indoor unit to release the warmth indoors.
- Heat Release: Inside the unit, the evaporator coil transforms into a condenser, emitting heat into the room, with a fan working to distribute the warmth.
Mini Splits vs. Heat Pumps
Although ductless mini split systems and heat pumps share many similarities, they are not quite the same.
- Mini Split System: A mini split system is a ductless HVAC solution, including both indoor and outdoor units connected by refrigerant lines. These systems can be heat pumps, but they can also be air conditioners without heating capabilities.
- Heat Pump Systems: A heat pump is an energy-efficient HVAC system that transfers heat to regulate temperatures, offering both heating and cooling capabilities. Compatible with mini splits and ducted systems, heat pumps can reverse the flow of refrigerant to adapt to the seasons, providing comfort year-round.
- Heating and Cooling: Heat pumps offer both heating and cooling by reversing the flow of refrigerant. In contrast, mini split systems may either provide only cooling (if not a heat pump) or both heating and cooling (if equipped with heat pump technology).
All mini splits are ductless, but not all have heat pump capabilities. Some mini splits are strictly for cooling. For those who want both heating and cooling in one system, mini splits with heat pump technology are the perfect solution. However, heat pumps are not limited to mini splits—they’re available in both ductless and ducted HVAC systems as well.
