Known for their world-class engineering, whisper-quiet performance, and zoned cooling capabilities, Daikin’s mini split systems deliver unmatched reliability for homeowners and businesses alike.
In this article, we’ll explore what makes Daikin’s ductless mini splits special, how they work, their key advantages, where they’re best used, and which models to consider in 2025.
—What Is a Daikin Ductless Mini Split Air Conditioner?
A Daikin ductless mini split air conditioner is a two-part HVAC system that provides heating and cooling without the need for air ducts. It consists of:
- Indoor Unit: Mounted on a wall, ceiling, or floor, it distributes conditioned air directly into a single room or zone.
- Outdoor Unit: Houses the compressor and condenser coil, usually installed outside the building.
These units are connected via refrigerant lines and a control cable, and they operate using Daikin’s advanced inverter compressor technology for precise climate control.
—How Does It Work?
Like all ductless split systems, Daikin mini splits operate using the vapor-compression refrigeration cycle:
- The indoor unit draws in warm indoor air and passes it over a cold evaporator coil.
- The refrigerant inside the coil absorbs the heat and evaporates into a gas.
- This gas is compressed in the outdoor unit and cooled back into a liquid, releasing heat outside.
- The refrigerant returns to the indoor unit to continue the cooling cycle.
Most Daikin mini splits are heat pumps, meaning they can reverse this process in winter to provide heating.
