Yes, Mitsubishi mini splits are energy efficient. Mitsubishi has expanded on inverter technology to make it very energy efficient. They've designed all their systems to use less energy vs. traditional HVAC systems. Even among mini-split manufacturers, Mitsubishi has some of the most efficient systems.
They're more efficient in lots of ways:
- Their inverter allows the system to adjust its speed and output based on the temperature needs of the room. That allows the system to operate a lower speeds & consume less energy. An added benefit is you maintain a consistent temperature in your room.
- Inverter-driven systems get to temperature much quicker using less energy.
- Mitsubishi systems usually have higher SEER and HSPF ratings than other mini splits.
- Their patented “flash injection” process on their Hyper-Heating INVERTER (H2i) systems. The flash injection uses a bypass circuit to reroute refrigerant. Refrigerant flows back to the indoor coil and the compressor to enhance heating.
