- Unlike traditional single-stage air conditioners that run full blast or not at all, the NAA Series uses inverter-driven technology to operate across a wide range of capacities - it’s like having a dimmer switch instead of an on/off switch. Each NAA AC unit covers a range of cooling output, rather than a single fixed tonnage. This approach allows the cooling system to run longer at lower speeds, minimizing energy consumption while providing closer temperature and humidity control, and improving overall comfort.
- Inverter-driven compressor continuously adjusts capacity to match demand
- Streamlined NAA model lineup eliminates the need for multiple fixed-capacity models
- Quiet operation supported by variable-speed performance and efficient airflow
- Optimized compatibility with Navien indoor HVAC equipment for reliable system matching
- Uses eco-friendly R454B low GWP refrigerant
