Navien announced the launch of three new HVAC products: the NAZ Air-to-Air Heat Pump, NAS Air Handlers and NAM Cased Coils. These products are designed to integrate with the NPF Hydro-furnace. The NAZ Air-to-Air Heat Pump is engineered to deliver performance with SEER2 ratings up to 19.0. Two SKUs cover a capacity range from 1.5 to 5 tons . Key features include long line set lengths up to 100ft, pre-charged for 25ft, Bluetooth connectivity, low GWP R-454B refrigerant, low sound levels, adaptive defrost and gold fin coil coating. 

The NAS air handlers are available in 2-5 ton capacities and feature a multi-position design. One model supports upflow, horizontal or downflow configurations with an optional kit. Designed for use with low-GWP R-454B refrigerant, they include a factory-installed refrigerant detection system. The NAS line features aluminum coil construction, quiet variable-speed SECM or ECM blower motors, and compatibility with 5–20kW electric heat kits. The NAM cased coils also support 2-5 ton applications and are designed for integration with Navien outdoor units and the NPF Hydro-furnace. These coils feature multi-position flexibility, are AHRI-matched and certified and include a factory-installed TXV and A2L refrigerant leak sensor. Each unit is leak-tested and pressurized, while germicidal light compatibility supports enhanced indoor air quality.
