This in-depth guide explores what sets Daikin apart, how their mini split systems work, product features, types of indoor units, pros and cons, and tips for choosing the right system for your needs.
Who Is Daikin?
Daikin Industries, Ltd. is a Japanese multinational air conditioning manufacturer founded in 1924. With over 90 years of innovation, Daikin is recognized globally as a pioneer in HVAC technologies, especially in inverter-driven compressors and eco-friendly refrigerants. Their commitment to sustainability, comfort, and reliability has made Daikin one of the most trusted names in ductless systems worldwide.
—What Is a Mini Split Air Conditioner?
A mini split air conditioner (also called a ductless split system) consists of two main components:
- Indoor Unit: Installed inside the room to deliver cooled or heated air.
- Outdoor Unit: Located outside the home, housing the compressor and condenser.
The units are connected via refrigerant lines, power cables, and drain hoses. This system eliminates the need for ductwork and offers individual zone control, making it highly efficient and customizable.
—How Do Daikin Mini Split Systems Work?
Daikin mini split systems use inverter-driven compressors to adjust cooling and heating output based on the room’s needs. This continuous adjustment offers:
- Stable indoor temperatures
- Lower energy consumption
- Quieter operation
The system draws warm indoor air across evaporator coils, which absorb the heat using refrigerant. The heat is transferred outside, and cooled air is blown back into the room. In heating mode (via heat pump), the cycle reverses.
—Key Benefits of Daikin Mini Split Air Conditioners
✔ Inverter Technology
All Daikin mini splits come with inverter technology, which modulates the compressor speed to maintain a consistent room temperature and reduce energy use by up to 30–40% compared to non-inverter models.
✔ Zoned Comfort
Each indoor unit can be controlled independently, allowing you to customize temperatures in individual rooms or areas—perfect for families, offices, or multizone applications.
✔ Whisper-Quiet Operation
Indoor units operate as quietly as 19 dB, making them ideal for bedrooms, nurseries, libraries, or offices.
✔ Compact and Flexible Design
Daikin offers various indoor unit types (wall-mounted, floor-standing, ceiling cassette) that fit a wide range of interior designs and spatial constraints.
✔ Eco-Friendly Refrigerants
Daikin uses R-32 refrigerant in many of its models, which has a lower Global Warming Potential (GWP) than traditional refrigerants like R-410A.
